FLIGHT CONTROLS NOTES:
Overview
The Falcon 7X aircraft is fitted with a Fly-By-Wire (FBW) system controlling the aircraft attitude on the three axes (pitch,
roll and yaw) to achieve the desired flight path according to pilot or auto-pilot commands by way of eight primary flight
control surfaces:
− Two Ailerons (L9500CR)/(R9500CR)
− Two Elevators (L9500CP)/(R9500CP)
− One Rudder (9500CL)
− One Horizontal Stabilizer (9500CH)
− Two Spoilers (L9501CR)/(R9501CR)
The control surface deflections are computed from signals transmitted by:
− Sidesticks
− Attitude and Heading Reference System (AHRS)
− Inertial Reference System (IRS)
− Air Data System (ADS)

Overview (Continued)
Modes of the FCS
In order to optimize flight safety, the FCS has three operating modes:
NORMAL Laws: In normal mode, full functionality is provided including all control augmentation, envelope
protection, and enhanced flying quality functions.
ALTERNATE Laws: Provide handling characteristics similar to those of the normal laws around 1g within a restricted
flight envelope. The applicable procedures are as if all the protections were lost, although some
of them may still be active. The FCS enters this mode automatically when NORMAL modes
cannot be supported due to failures in computation, servo-actuators, sensors or interfacing
system.
DIRECT Laws: Implement the minimum functions enabling a safe flight and landing. The FCS enters this mode
automatically when NORMAL / ALTERNATE modes cannot be supported due to failures in
computation, servo-actuators, sensors or interfacing system.
In addition, an independent BACK-UP mode is provided.
BACK-UP: This mode is entered when the NORMAL, ALTERNATE and DIRECT modes are lost. It consists
in direct control laws from dedicated pilot transducers to the horizontal stabilizer (9500CH) and
the spoiler actuators (L101CR)/(R101CR). Unlike the NORMAL, ALTERNATE and DIRECT
modes, the BACK-UP mode is designed to operate temporarily while the crew attempt to recover
one of the upper modes.
A set of electro-hydraulic and electric actuators performs the actuation of the eight primary control surfaces:
− Seven electro-hydraulic servo-actuators:
• LH Aileron (L9500CR) and RH Aileron (R9500CR) (one dual-barrel servo-actuator on each side)
• LH Elevator (L9500CP) and RH Elevator (R9500CP) (two single-barrel servo-actuators on each side)
• Rudder (9500CL) (one dual-barrel servo-actuator)
− One Electric Actuator: the HSTA (101CH) and its associated electrical control units (the HSECU (301CH) for the
HSTA motor 3 (9510CH) and the HSTA motor 4 (9520CH), the HSEBU (401CH) for the HSTA back-up motor
(9530CH))
− Two spoiler actuators (L101CR)/(R101CR) and their associated electrical control units, the Spoiler Power Control Unit
(SPPCU) (301CR) (with a hydraulic back-up)

The FCS maintenance and avionics interface function provides the following:
The computation of control laws is ensured by two types of computers: − System in-flight continuous monitoring of the FCS health. Each MFCC and SFCC sends its own safety device data to

Depending on the FCS electrical or mechanical failures, the MFCCs implement three modes of computation: − On-board maintenance capabilities: processing of the system in-flight continuous monitoring data in order to identify
− Normal Mode the possible failed function, and implementation of pre-flight and ground maintenance tests
− Alternate Mode

which are sent to the ACMU. The SFCC is composed of three hardware- and software-identical channels. Each single
channel SFCC (i=1,2,3) provides the nine primary surface commands in the DIRECT mode.
In order to have the same three input vectors, the input vector of a channel is exchanged with those of other channels.
The surface command outputs (one per SFCC channel) are consolidated at the input of the actuator servo-loops in the
ACMU.
A BIT is started at each power up. This BIT is in charge of detecting any internal failure.
The three SFCCs are respectively supplied by the electrical power sources E1, E3 and E4.

and the RH rudder/brake pedals (R201CL)
The processor of each of the two lanes (A and B) performs several functions: − One SENSORS - MON board (SEN) which performs the conditioning of all spoiler sensors and the management of
− Slaving the actuators sensors and spools
− Controlling the servo-loop: it monitors the outputs of the other lane and disengages the module functionality if a − Two SPOILERS CTRL boards (SPCA/SPCB) which perform the analog slaving function and Electrical Back-up

and the drive motor of an actuator • The spoiler control and EBHA management in normal mode
• The test processing for the spoilers and the HSTA Back-up function
There are four types of servo-loop modules: − Two Roll rate gyros (GYA/GYB) respectively dedicated to lanes A and B, and used to process the Spoiler B/U
− Two types of actuator control modules, named Actuator Control A (ACA) and Actuator Control B (ACB), for monitoring command (HSSA/HSSB boards)
the elevators, the ailerons and the rudder.
In addition, for actuation of the spoilers (Normal and BU mode) and for the HSTA back-up motor (9530CH), the FCS
includes one back-up electronic box (105CZ) with several boards.
Inputs / Outputs
The inputs and outputs are:
− Actuator position command from SELMON and engagement request status
− Actuator position servo-loop
− Hydraulic pressure sensor
− Spool position sensor
− Selector sensor
− EV relay command
− Actuator command
− Information regarding the engagement of the other servo-actuators
The module interfaces several engagement status signals from other modules.
Sensor Interfaces
Two ACA (or ACB) modules interface five Linear Variable Differential Transformer (LVDT) sensors from each servo-
actuator. The first ACA module interfaces LVDT Feedback, spool and selector sensors, the second ACA module
interfaces monitoring and accumulator LVDT sensors. A special ruggedized ±15V power supply is used to supply sensor
interface and sensor pressure.

The cockpit controls and Flight Controls System (FCS) indications are:
− Control of the sidestick lock solenoid to neutral position when the AutoPilot (AP) is engaged
− Pilot Sidesticks (101CK) and (201CK) for Pitch and Roll Control, Priority Selection, Quick Disconnect and Touch
Control Steering (TCS) − Control of the vibrating solenoid
− Rudder and Brake Pedals Assemblies (RBPA) (L201CL) And (R201CL) For Yaw Control
− Trim Unit (106CZ) for Yaw, Pitch and Roll Trim Unit
− SFAU (9001CF) The trim unit (106CZ) is located on the pedestal. The function consists in providing manual trim control on the three axis
when “Normal” control laws are failed. The trim unit interfaces with the FCS. It includes:
− Overhead Panel (5000PM)
− Three trim control dual rockers:
− Configuration/Warning Panels (L1000FW) And (R1000FW)
• “PITCH” Trim Control Dual Rockers
− Multi-Function Display Units (MDU): Upper MDU (M101FD) and Lower MDU (201FD)
• “YAW” Trim Control Dual Rockers
− Primary Display Units (PDU): LH PDU (L101FD) and RH PDU (R101FD)
• “ROLL” Trim Control Dual Rockers
• a lighting panel
Sidesticks (101CK/201CK)
The aircraft is fitted with two independent sidesticks (101CK) and (201CK), one for the pilot and one for the copilot. The
force feedback is provided by mechanical elements (spring, fluid damper, …). The two sidesticks (101CK) and (201CK)
are independent (they are not mechanically / electrically linked). The functions of the sidesticks (101CK) and (201CK) are:
− To measure the pilot order through two directions (pitch and roll)
− To transmit the pilot commands to the Flight Control System (FCS)
− To provide the pilot with a force feedback Trim Unit (106CZ)
− To add a force threshold at neutral when autopilot is engaged (to lock at neutral)
− To provide, through the control handle, commands to radio system, autopilot and priority between pilot and copilot
The sidestick interfaces with the FCS, the Automatic Flight Control System (AFCS), the communication system and the
Head-up Guidance System (HGS). Each sidestick includes:
− One pilot sidestick handle (9530CK) /(9540CK) with four pushbuttons:
• Priority/AP Disconnect Pushbutton
• TCS (Pitch Synchronizer) Pushbutton
• Enhanced Vision System (EVS) Declutter Pushbutton (when EVS option is not installed, this pushbutton is not

DIGITAL FLIGHT CONTROL SYSTEM (DFCS) (CONTINUED)
Components (Continued)
Rudder / Brake Pedal Stations (RBPS) (L201CL/R201CL)
There are two redundant RVDT for each RBPS to provide inputs to the aircraft flight control system. Each RVDT is geared
to the transfer yoke by a single gear and sector, mating with a anti-backlash gear on each pedal. One of these redundant
RVDT is used to provide inputs to the steering system. One potentiometer is installed as a back-up for each RBPS.
There are two redundant Linear Variable Differential Transducer (LVDT) for each RBPS to provide inputs to the brake
control system when the pedal is depressed. A re-centering / feel mechanism produces artificial feel for the pilots and
causes the pedals to return to neutral position after pilot input.
NOTE: For aircrew ergonomics, each RBPS includes an electrical pedal height adjustment mechanism. Using
cockpit controls, the electrical adjustment mechanism allows the pilot to find a comfortable pedal height.
In the event that the electric adjustment of the RBPS pedals is not available, manual adjustment of the pedals is available.
Use the tool used to adjust the height of pilot seats. The tool must be inserted into the adjustment nut on the plate on the
top of the RBPS.
Connecting Rod
The RBPS are linked together by an adjustable connecting rod so that each pilot is always informed of the flight crew
input.
NOTE: The length of the rod can be adjusted upon assembly, such that the rudder-centered positions of each
assembly are coincident.

DIGITAL FLIGHT CONTROL SYSTEM (DFCS) (CONTINUED)
Operation − Four Maintenance and Avionics Interface Computers (MAIC) provide:
The functions performed at system level by the FCS are the following: • System in-flight continuous monitoring
− Detection of pilot commands (pitch, roll, and yaw), including artificial feel function • Messages to the Crew Alerting System (CAS), FCS synoptics, data to other systems. These messages contain
internal PFCS status data such as:
− Interface with pilot input transducers and aircraft sensors
▪ Mode (Normal laws, Alternate laws, Direct laws)
− Control law computation from pilot commands, auto-pilot commands and aircraft sensors
▪ Actuator statuses (failures detected)
− Control of the actuators, including implementation of servoloops
▪ Computer statuses (failures detected)
− Actuation of the eight primary flight control surfaces
▪ On-board maintenance capabilities including ground maintenance tests
− In-flight continuous monitoring of the system and peripheral components in order to:
▪ Flight Data Recorder (FDR) data transmission
• Determine the integrity of the various system components
▪ Auto-pilot outer loop interface
• Elaborate and send messages to the Crew Alerting System (CAS). These messages are used by the CAS to
display warning, caution, and advisory messages to the crew − A set of electro-hydraulic and electric actuators performs the actuation of the eight primary control surfaces:
− Elaboration and transmission of data to the Flight Data Recorder (FDR) • Seven electro-hydraulic servo-actuators:
− Integrated maintenance functions to identify the failures present in the system and to assist in their repair ▪ The LH aileron (L9500CR) and the RH aileron (R9500CR) (one dual-barrel servo-actuator on each side)
− Implementation of ground maintenance tests for detection of dormant failures, confirmation of repair action, ▪ The LH elevator (L9500CP) and the RH elevator (R9500CP) (two single-barrel servo-actuators on each side)
complementary troubleshooting information. ▪ The rudder (9500CL) (one dual-barrel servo-actuator)
• One electric actuator: the HSTA (101CH) and its associated electrical control units (the HSECU (301CH) for the
These functions are performed as follows: HSTA motor 3 (9510CH) and the HSTA motor 4 (9520CH), the HSEBU (401CH) for the HSTA back-up motor

one trim unit (106CZ). Unit (SPPCU) (301CR) (with a hydraulic back-up)
− Inputs from the pilot controls, auto-pilot commands, aircraft motion information from the air data and inertial sensors,
as well as all needed discrete and analog FCS inputs are received by five Flight Data Concentrators (FDC), where
they are digitized if necessary, and then sent on serial data links to the Main Flight Control Computers (MFCC) and
Secondary Flight Control Computers (SFCC).
− Two sets of digital Flight Control Computers (FCC) provide for the computation of control laws, based on the FCS
input data transmitted by the FDCs:
• Three MFCCs perform the vote-processing of the sensors and the computation of the NORMAL, ALTERNATE or
DIRECT laws. Each MFCC is dual-channel. This allows one MFCC to continue operating after the loss of the
other two MFCCs. Consolidation of MFCC commands and detection of failures are also performed by the
Actuator Control and Monitoring Units (ACMU),
• Three SFCCs perform the vote-processing of the sensors and the calculation of the DIRECT laws. Each SFCC
has a single computation channel. Consolidation of SFCC commands and detection of failures is also performed
by the ACMUs.
− The back-up electronic box (105CZ) provides commands for the spoilers (the back-up electronic box also contains a
specific digital board which controls the two spoilers (L9501CR)/(R9501CR) when the PFCS is operating per the
NORMAL, ALTERNATE or DIRECT laws) and for the Horizontal Stabilizer Trim Actuator (HSTA) (101CH) in back-up
mode.
− The pilot input transducers used in the B/U (Back-Up) mode are separate from those used by the MFCCs and SFCCs.
However, the trim lever inputs are the same for pitch manual trim as for B/U, but they use separate contacts. Some
contacts are dedicated to PFCS control laws through the FDCs. The other contacts are used by the back-up
electronic box (105CZ).
− Four ACMUs perform the following:
• Elaboration of actuator commands by consolidation (failure detection and selection) of FCC outputs through the
SELection and MONitoring Unit (SELMON).
• Control and servoloop implementation, and monitoring of the electric and electro-hydraulic actuators (servoloop).

MFCC/SFCC Channel Eligibility
The validity of the xFCC is determined during the vote processing. However, before performing the vote, the ACMU must
determine which channels are eligible for each FCC.
Each SELMON lane A receives data from each MFCC lane A, and each SELMON lane B receives data from each MFCC
lane B. Each MFCC lane sends the data from both lanes. The lane A of each MFCC channel sends data of lane A and B
and, similarly, the lane B of each MFCC channel also sends data of lane A and B. This data contains actuator commands,
with their offset and discrete information.

Maintenance Considerations After a flight, when FCS failures have been reported, the maintenance technician must configure the aircraft for
troubleshooting. Using the CMC to analyze FCS failures requires energizing the aircraft systems (E1, E2, E3, E4) and

pressurizing the hydraulic systems (A, B, C) to prevent false failures due to an incorrect configuration.
The maintenance function provides a diagnosis of the FCS (Flight Control System) before each flight, and manages the
historical record of FCS statuses over “n” consecutive flights. The purpose of the maintenance function is to detect and
locate failures in the FCS system. The maintenance function ensures the following tasks: With the aircraft systems energized with GPU, the “TEST E1” and “TEST E2” switches will be set to the ON position to
observe the configuration with 4 electrical power sources.
− Detection of failures that have an impact on aircraft dispatch, either on ground before the flight, or in flight for a
possible diversion to an airport with maintenance facilities
− Reporting and recording of any elementary failure of the FCS system The maintenance technician must run a FCS ground test, then check the "Active Maintenance Messages" from the CMC,
and troubleshoot successively each of these "Active Maintenance Messages”.
Fault detection is mainly based on operational safety devices which monitor the functions relating to safety and system
availability: These maintenance messages are classified per ATA chapters and sections (ATA 27 for the FCS). According to the
number of failures recorded, there may be several maintenance messages distributed in several ATA sections (27-00 /

− Filtering of failures detected in flight or during tests, to generate the relevant Fault reports sent to the Centralized
Maintenance Computer (CMC) and used to locate faulty equipment items Recommendation
If several LRUs of different types are indicated as "Possible LRU at fault" in a Maintenance Message, the maintenance
technician must proceed in the following sequence:
The maintenance function is implemented in the Maintenance and Avionics Interface Computers (MAIC) which interface
with the two Modular Avionics Units (MAU) of the EASy avionics. 1. Replace first the indicated electronic module(s) and validate their replacement by running a Ground Test,
2. If the failure persists, replace the mechanical or hydro-mechanical LRUs and validate their replacement by
running a Ground Test.
FCS failures are divided in three categories:
− Failures preventing next flight: NO DISPATCH

The Maintenance of the Flight Control System (FCS) is based on three components: The purpose of the information provided by the Maintenance Messages, whenever possible, is to identity the LRU(s)
failed, following the display of a CAS Message or of a Fault Message indicating a failure.
− Pre-flight test for FCS integrity check: Pre-Flight Test (PFT)
− Permanent monitoring throughout the flight. This monitoring ensures: Principle
• Detection of failures through the operational safety devices monitoring the different functions The FCS includes about a hundred different LRUs, such as:
• Eleboration and transmission of FCS warnings to the MAUs − Hydraulic Actuators
• Recording of basic failures for maintenance purpose and for updating the DISPATCH status − Electric Actuators
− Complementary ground tests: Ground Maintenance Tests (GMT), performed after a failure for troubleshooting or − Mechanical Devices Such As Sensors, Trim Unit, Microswitches

− FCS Rack Containing The Electronic Modules
− Electronic Modules

− Electronic Units
This test is performed to check the FCS for correct operation before a flight. It also activates and checks some redundant
FCS functions which are not active in the nominal mode. The result of the PFT can be DISPATCH (flight authorized) or The FCS exchanges data, over dedicated links, with other aircraft systems, such as MAUs, AHRS, IRS, ADS, WOW,
NO DISPATCH (flight not authorized - Troubleshooting requested). The flowcharts provided, define the PFT running SFAU, TCU, overhead panel and BCU. The FCS contains four MAIC modules, which send the same data at the same
process, and the actions to be done according to the test result. moment to the Generic I/O modules of the MAUs over four ARINC links. The EASY system performs an "OR" between
the data delivered by the four MAICs, before recording it in the "CMC " data base for use as Maintenance Messages.
The duration of the PFT is approximately 1 minute. The PFT checks for correct operation of the FCS through its testable
modules, i.e.: Three categories of messages are generated for each LRU:
− MFCCs − Internal Failure:
− SFCCs • Which groups all the possible internal failures for the indicated LRU,
− SFCIs − Communication Interface Failure:
− MAICs • Which groups the failures of the serial data links between the indicated LRU and the other LRUs belonging to the
FCS. Depending on the architecture, this communication interface failure can occur as a single failure or in

The purpose of Maintenance Screens generated from the "parameter monitoring" CMC function is to help the
maintenance technician to:
The maintenance technician can refer to the associated maintenance documentation to find additional information which
− Cross-check, if in doubt before replacing (a) failed LRU(s), may help him identity the faulty LRU(s).
− Validate the replacement of (a) LRU(s) after troubleshooting,
− Run triggered tests from the Maintenance Screen, when applicable.
"Parameter Monitoring" is a CMC functionality which provides real-time display of the statuses or values of all parameters
circulating over the communication bus of the EASY (ASCB) system.
Principle
The Maintenance Screens are presented per function in each ATA section and contain the functional data and the failures
associated to that function. The failures displayed in these screens are identical to those identified in the Maintenance

AILERON AND SPOILER CONTROL SYSTEM
Overview A variable heating device meant to improve operation in cold temperature.
The aileron and spoiler control system perform the roll control: The two barrels of the LH aileron servo-actuator (L102CR) are controlled by the four Servoloop modules:
− Actuation and monitoring of the position of the two ailerons − LH Aileron N1 Module (604CZ)
− Actuation and monitoring of the position of the two spoilers − LH Aileron N2 Module (504CZ)
− LH Aileron S1 Module (1203CZ)
The aileron and spoiler control system includes the sub-subsystems that follow: − LH Aileron S2 Module (1103CZ)
− Spoiler Control System
− Aileron Control System LH actuator barrel N is powered by hydraulic system A and controlled through electrical generations E1 or E4.
LH actuator barrel S is powered by hydraulic system B and controlled through electrical generations E2 or E3.
AILERON CONTROL SYSTEM
The two barrels of RH aileron servo-actuator (R102CR) are controlled by the four Servoloop modules:

or in case of hydraulic supply loss.
− Two cylinder chamber pressure sensors allowing the implementation of an anti-flutter automatic test, and also used as
inputs to the Fighting Force Detection Test (FFDT).
− Accumulator and a check valve located on the return line. These devices retain hydraulic fluid in the barrel in the
event of pressure drop and guarantee the damping system to correctly operate during a specified duration after
hydraulic system loss. A LVDT allows the accumulator position to be monitored.

AILERON CONTROL SYSTEM (CONTINUED)
Operation The pressure sensors fitted in each chamber allow checking periodically for the efficiency of the anti-flutter protection
(Anti-flutter Automatic Test).
Logic of Engagement
The N and S barrels of the aileron servo-actuators (L102CR) and (R102CR) are active simultaneously. The only switching
possibilities for N1, N2, S1, S2, are N1 to N2 and S1 to S2. It is impossible to have N1 and N2 or S1 and S2 engaged
together.
There are three possible operating modes: normal, damped and anti-flutter.
Normal Mode
Both barrels are simultaneously active. The input order is provided, for each barrel, by the servo-loop modules on two
separate channels (A and B) with permanent mutual comparison for monitoring purpose. Two electric inputs provided by
two servo-loop modules are available on each barrel, with only one being active, and with switching on the second one in
case of failure of the primary one.
The actuator position feedback is obtained through comparison between the input order and the actual actuator position,
measured by a double LVDT attached to the body and to the piston. One LVDT signal is active for feedback; the other
one performs a monitoring function through comparison with the first one. In order to avoid a common point failure, the
barrel N (resp. S) feedback sensor is compared to the monitoring S (resp. N) sensor.
The position/order difference is converted into an electric signal sent by one Servoloop module, on two separate channels
(A and B), to the two coils of a linear motor, that directly drives the main spool valve, thus controlling the pressure and
flow in the cylinder chambers. The motor coil current determines a displacement of the spool, measured by a LVDT. The
LVDT information is also used for monitoring purpose. The comparison between the position and the current realizes the
feedback inner loop, with the help of a leaf spring for stability purpose.
The electric control is made active through the energization of a solenoid valve, the authorization of which depends on the
status of the related safeties (Or Faulty logic). The solenoid valve utilization chamber controls a selector valve which,
when in open position, hydraulically connects the spool valve utilization ports to the cylinder chambers. The selector valve
is fitted with a LVDT for monitoring purpose.
The selector valve spool is pushed back by a spring in closed position, where:
− Spool valve utilization ports are isolated from the cylinder chambers
− Spool valve supply port is connected to the return line
− Cylinder chambers are interconnected through a calibrated orifice, generating a counteracting differential pressure
when the servo-actuator is ordered from one position to another
Both barrels are simultaneously operating in damping mode. The protection against flutter is ensured by a set of check
valves, and by an accumulator fitted with a LVDT, used for monitoring purpose. The accumulator is meant to provide the
cylinder chambers with hydraulic fluid in order to compensate for possible seepage. The LVDT allows checking for proper Figure 41
operation of the accumulator and checking valves. A thermal valve protects the body against possible overpressure. RH Aileron – Engagement Exchanges

SPOILER CONTROL SYSTEM
Overview
The aircraft is fitted with one spoiler on each wing. The spoilers are located between the inboard and outboard airbrakes.
The system is powered by electrical power supply E4 and by hydraulic system C. The logic for the LH and RH spoilers is
controlled by the servo-loop spoiler control A (SPC A) and spoiler control B (SPC B) in the back-up electronic box
(105CZ). The spoiler control system can be activated according to the following functions:
Spoiler Servo-Loop A and B in the Back-up Box (105CZ)
− Airbrake function as per the position of the Slat/Flap/Airbrake Unit (SFAU) (9001CF)
• AB0: Full Retraction
• AB0 to AB1: Progressive Extension
• AB1: Full Extension
− Additional roll capability function according to the flight control laws
− Roll capability in Back-Up mode, using dedicated inputs:
• One pedal dedicated transducer
• Two roll rates
pressure drop occurs in flight. During landing, it remains active as long as the ground speed is above 30 kt The spoiler
control system includes:
− LH Spoiler Actuator (L101CR) and RH Spoiler Actuator (R101CR)
− LH Spoiler Sensor (L201CR) and RH Spoiler Sensor (R201CR), including two dual Rotary Variable Differential
Transformers (RVDT) for position measurement purposes
− Spoiler Power Control Unit (SPPCU) (301CR), including a standby electric pump meant to keep controlling the
actuators in case of hydraulic system loss
− Spoiler Electrical Control Unit (SPECU) (401CR), providing electrical power to the standby electric pump.
Components
Actuators
The LH spoiler actuator (L101CR) and the RH spoiler actuator (R101CR) are identical. The retraction chambers are
permanently submitted to the supply pressure. The extension chambers are submitted to a controlled pressure out of the
SPPCU (301CR). Each actuator includes:
− A housing fitted with hydraulic couplings
− A bearing and a nut
− A piston and an attachment rod fitted with a greaser
Position Sensors
The LH spoiler sensor (L201CR) and the RH spoiler sensor (R201CR) are identical. Each one includes:
− An output lever for connection to the control surface,
− A housing fitted with an electric connector,
− A dual RVDT driven by the output lever. A torsion spring brings back the RVDT on the extended mechanical stop in
case of lever disconnection, thus commanding the retraction of the control surface.

SPOILER CONTROL SYSTEM (CONTINUED)
Components
Spoiler Power Control Unit (SPPCU)
The SPPCU (301CR) includes the following components and subassemblies:
− A power control block fitted with hydraulic couplings
− A filter and a check valve on the high pressure line
− A solenoid valve switched on when the control is operative, switched off in case of failure
− Two Direct Drive Valves (DDV), one per actuator control, including a force motor directly driving a spool valve and an
associated Linear Variable Differential Transformer (LVDT) for position measurement purposes
− A selector spool valve controlled by the solenoid valve utilization pressure and allowing hydraulic supply to both DDVs
− A LP check valve maintaining the low pressure at a preset value
− A HP calibrated pressure relief valve, for overpressure protection Spoiler Power Control Unit (SPPCU) (301CR)
− A manual depressurization valve for ground maintenance purposes
− A high pressure sensor
− A high pressure switch
− A low pressure sensor
− A standby electric pump
− A reservoir for the electric pump circuit
− An accumulator for the electric pump circuit
− A check valve meant to isolate the electric pump HP line from the aircraft main supply line
The main function of the SPECU is to drive the motor in accordance with the orders received from Spoiler Servoloop
control boards. The SPECU is then composed of the power electronic device in one hand and the regulation and control
electronic device in the other hand. It receives signal from the Hall effect sensors of the motor and the ON/OFF command
of the brushless motor from Spoiler Servoloop control boards. Moreover the SPECU will inform the Spoiler Servoloop
control boards (in case of failure of itself or of the motor) thanks to a BIT made before each flight.

when no order is given. The input order is provided by SPC A and SPC B on two separate lanes (A and B) with
permanent mutual comparison for monitoring purposes. NOTES:
The actuator position feedback is obtained through comparison between the input order and the actual actuator position,
measured by the position sensor attached to the control surface. One RVDT signal is active for feedback, the other one
performs a monitoring function through comparison with the first one. The position/order difference is converted into an
electric signal sent by SPC A and SPC B to the two coils of a linear motor, that directly drives the main spool valve, thus
controlling the pressure and flow in the actuator extension chamber.
The motor coil current determines a displacement of the spool, measured by a LVDT. The LVDT information is also used
for monitoring purposes. The comparison between the position and the current provides the feedback inner loop, with the
help of a leaf spring for stability purposes.
In case of overpressure in the high pressure line, a calibrated pressure relief valve opens and evacuates the pressure
towards the return pressure line. This pressure relief valve is held closed by a spring in normal conditions.
The electric control is made active through the energization of a solenoid valve, the authorization of which depends on the
status of the related safeties (Or Faulty logic). The solenoid valve utilization chamber controls a selector valve which,
when in open position, hydraulically supplies the DDV spools. In case of failure, depending upon its type, one or both
spoilers are maintained in retracted position by the high pressure present in the retraction chambers.
Isolated Mode
In case of failure of the aircraft hydraulic system C, the aircraft circuit becomes isolated through the closing of the high
pressure check valve and of the calibrated return pressure relief valve.
The engagement of the hydraulic local generator is commanded by the high pressure switch. To be valid, this information
must be confirmed by the information given by the pressure sensors on the high pressure line and the return pressure
line, and by a built-in test provided by the SPECU (401CR). Each SPC emits an enable signal towards the SPECU
(401CR).
The local generator is composed of a brushless motor fitted with Hall effect sensors, an SPECU (401CR) and a gear
pump, meant to ensure the spoilers actuation. The generator includes a reservoir and an accumulator, integral to the
SPPCU (301CR).
The pump cycling is determined by the high pressure value, measured by a sensor. Another pressure sensor on the
return pressure line checks for the proper filling of the reservoir. The position control and related safeties are the same as
in Normal mode.

surface side by two single barrel servo-actuators, hydraulically supplied through a pressure reducing valve.
− The reducing valve AB (301CP) for the LH elevator (L9500CP)
− The reducing valve AC (401CP) for the RH elevator (R9500CP)
All four elevator servo-actuators (L101CP), (L201CP), (R101CP) and (R201CP) are strictly identical. The two barrels
related to one elevator are conventionally called N and S. The assembly is of the moving piston and oscillating body type.
The LH outboard servo-actuator (barrel N) is powered by hydraulic system A and controlled through power sources E1
and E4.
The LH inboard servo-actuator (barrel S) is powered by hydraulic system B and controlled though power sources E2 and
E3.
The RH inboard servo-actuator (barrel N) is powered by hydraulic system C and controlled though power sources E2 and
E3.
The RH outboard servo-actuator (barrel S) is powered by hydraulic system A and controlled though power sources E1
and E4.
Components
Elevator Servo-Actuators
Each elevator servo-actuator (L101CP), (L201CP), (R101CP) and (R201CP) includes a cylinder and its associated piston
and bearings. The piston rod is fitted with a double Linear Variable Position Transducer (LVDT) for position measurement
purposes.
Each elevator servo-actuator (L101CP), (L201CP), (R101CP) and (R201CP) includes a power control block including:
− A filter and a check valve on the hydraulic supply line
− A solenoid valve switched on when the barrel is active, and off when the barrel is failed
− A Direct Drive Valve (DDV) including a force-motor directly driving a spool valve and an associated LVDT position
transducer
− A selector spool valve controlled by the solenoid valve utilization pressure and allowing either the spool valve to
supply the barrel cylinder chambers (solenoid valve switched on) or to connect the cylinder chambers to the damping
system (solenoid valve switched off). A LVDT allows the selector spool position to be monitored
− A set of check valves and calibrated orifices allowing the actuator damping function when the solenoid valve is
switched off or in case of hydraulic supply loss
− Two cylinder chamber pressure sensors allowing the implementation of an anti-flutter automatic test, and also used as
inputs to the Fighting Force Detection Test (FFDT). Fighting force may occur on servo-actuators when both are
simultaneously active. It is generated by electronic and mechanical position deviations between the two barrels, and
its detection generates a trimming correction
− An accumulator and a check valve located on the return line. These devices retain hydraulic fluid in the barrel in the
event of pressure drop and guarantee the correct operation of the damping system during a specified duration. A
LVDT allows the accumulator position to be monitored
Each power control block include a set of devices dedicated to the centered mode, including:
− A solenoid valve acting on a piston, meant to forbid hydraulically the Centered Mode when operating in Active mode
− A selector spool valve, fitted with restrictors, allowing the switching to Centered Mode
− A bypass valve

RUDDER
Overview
The aircraft is fitted with one rudder (9500CL). The rudder control is ensured by a dual-barrel parallel-mounted servo-
actuator. The two barrels used for rudder control are conventionally called Normal (N) and Standby (S). The assembly is
of the moving piston and oscillating body type.
The rudder control subsystem performs the yaw control: actuation and monitoring of the position of the rudder (9500CL).
The rudder control subsystem interfaces with the Electrical Flight Control System (EFCS) which sends the information to
the EASy avionics system for display of the associated indications in the cockpit. The rudder control system also includes
the following sub-subsystem:
− Rudder and Brake Pedal Assembly
Rudder Servo Attachment
Components
Rudder Servo-Actuator (103CL)
Each barrel includes:
− Cylinder and its associated piston with two symmetrical strokes. The piston rod is fitted out with a dual LVDT position
transducer. Each barrel is fitted with 2 fasteners, one to attach to the structure and one to attach to the control
surface.
− Power control block including:
• Filter and a check valve on the hydraulic supply line
• Solenoid valve switched-on when the barrel is active
− Direct Drive servo-Valve including a force-motor directly driving the main spool valve and the associated single LVDT
position transducer.
− Servo valve is capable to be driven by two independent ACMU control channels (supplied by 2 different electrical
power sources).
− Selector spool controlled by the solenoid valve pressure and allowing either the main spool valve to supply the barrel
cylinder chambers (solenoid valve switched-on) or to connect the cylinder chambers to the actuator damping system
(solenoid valve switched-off). A single LVDT position transducer allows the selector spool position to be monitored.
− By-pass spool controlled by the solenoid valve pressure. This spool has 3 positions (active, damped and by-passed)
and there is a mechanical action between the by-pass spools of each barrel. So, when the solenoid valve of the first
[respectively the second] barrel is switched-on (then the solenoid of the second [respectively the first] is necessary
switched-off), the by-pass spool of this barrel is in the “active” position, and the by-pass spool of the other barrel is in
the “by-passed” position. When the solenoid valves of the two barrels are switched-off, the by-pass of the two barrels
is in “damped” position.
− Set of check valves and calibrated orifice providing anti-flutter actuator damping function when the solenoid valve is
switched-off or in case of hydraulic supply loss.
− Two cylinder chamber pressure sensors allowing the implementation of anti-flutter system periodic test.
− Accumulator and a check valve located on the return circuit. These devices retain hydraulic fluid in the barrel in the
event of pressure drop and allow the anti-flutter damping system to correctly operate during the required time period.
A single LVDT position transducer will provide accumulator functional testing capability.

the status of the related safeties (or faulty logic). The solenoid valve utilization chamber controls a selector valve which,
when in open position, hydraulically connects the spool valve utilization ports to the cylinder chambers.
The other barrel, the so-called Standby barrel, is not electrically controlled. Its solenoid valve is not energized. The
cylinder chambers are interconnected via a hydraulic bypass, thus providing a calibrated damping effect.

ELEVATOR, AILERON AND RUDDER SERVO ACTUATOR MONITORING LOGIC
Overview
Logic of Engagement Principle
Each ACA (or ACB) module is assigned to a command lane on one actuator (N1 or N2 - S1 or S2). The switching
between modules is performed by relays.
Each module includes two identical lanes, named A and B. For the effectiveness of the actuator engagement, the two
lanes A and B must be engaged. The two signals of engagement (lane A and B) of one module are sent to the other
modules. Then, each lane A and B can detect a failed engagement on the adjacent module.
Monitoring Logic
Various monitoring functions are performed within each servo-control Digital Signal Processor (DSP) of the servo-loop,
that can lead to an "Or Faulty" signal and to the opening of shutdown switches.
The "Or Faulty" elaborated by the DSPs of the ACMU in control is sent to the DSPs of the "Passive" ACMU to allow them
to take control.

HORIZONTAL STABILIZER
Overview
The aircraft is fitted with a horizontal stabilizer (9500CH). It is controlled by an electromechanical actuator fitted with three
electric motors. Two motors are powered by a Horizontal Stabilizer Electronic Control Unit (HSECU) (301CH). The third
motor is powered by a Horizontal Stabilizer Electronic Back-up Unit (HSEBU) (401CH). A Horizontal Stabilizer Sensor
Unit (HSSU) (201CH) provides the feedback and monitoring position data.
A new power source control system for the Horizontal Stabilizer has been added with SB-211R2 (M1235 and M1236)
which can be activated automatically by the DFCS or manually by the crew using the newly added TRIM EMERG switch
on the Emergency Panel (1001FW). This function removes E3 and E4 power from the HSECU (301CH) and forces
activation of the HSEBU (401CH). The purpose of this modification is to prevent uncommanded pitch trim movement.
Components
Contactors or Relays 3311CH and R3311CH
Contactor or Relay 3311CH is installed on the feeder cable between the LH PPDB and HSECU to interrupt the E3 power
supply to the HSECU.
Contactor or Relay R3311CH is installed on the feeder cable between the RH PPDB and HSECU to interrupt the E4
power supply to the HSECU.
NOTE: when working on this system, be sure that you are using the correct wiring diagram for your installation.

Test Connectors (2746J and 2747J)
Two test connectors are located in the baggage compartment above the LH PPDB (5000PC) and RH PPDB (6000PC).
These test connectors are used to test the operation of the control relays 3312CH, 3313CH, R3312CH and R3313CH.
In back-up mode, the brush motor fail-safe brake is disengaged to drive. Channels 3 and 4 brakes ground the differential
sun gear to allow the back-up motor to drive through the differential.
Each of the three motors can drive the ballscrew output through the multi-stage, speed-reducing, single load path, spur
gearbox. Irreversibility is provided by a bi-directional skewed roller no-back assembly at the ballscrew thrust flange, which
holds the horizontal stabilizer in the commanded position.
A torque limiter provides internal jam protection and limits the HSTA output force in case of surface jam. Non-jamming
mechanical stops at both ends of the ballscrew provide overstroke protection.
The secondary structural load path, including a tie rod running through the center of the ballscrew and an inverted thread
secondary nut connecting the ballscrew to the horizontal stabilizer through a secondary load path extension tube, ensures
fail-safe connection in the event of a primary load path failure.

Horizontal Stabilizer Electronic Control Unit (HSECU) (301CH)
The design of the secondary load path is such that the actuator will be locked in place after primary load path failure.
Each motor drive unit includes inductive sensors for motor current monitoring.

Operation Manual Safety Loop
The system architecture consists of a three-channel redundancy system. The three channels are labeled Channel 3 / − New TRIM EMERG pushbutton on the Cockpit Emergency Panel
Channel 4 and Backup. Their operation is based on the following: − If ultimately needed, the crew can push the button to:
− Channel 3: Permanently engaged and active • Shutdown E3 and E4 electrical power, stopping any trim runaway
− Channel 4: Engaged when channel 3 or HSTC 3 module has failed • Ensure both ACMUs will revert to the Backup Computer
− Back-up: The back-up mode is engaged when both channel 3 or the HSTC 3 module (403CZ) and channel 4 or • Allow the crew to use the manual pitch through the Backup Motor
the HSTC 4 module (1304CZ) have failed. Once this channel is activated it will maintain direct and
dedicated control of the HSTA
The HSECU (301CH) channel 3 is powered by power source E3 and receives input signals from the HSTC 3 module
(403CZ). This channel drives its own dedicated brushless motor (motor 3) and controls the brakes of motors 3 and 4.
The HSECU (301CH) channel 4 is powered by power source E4 and receives input signals from the HSTC 4 module
(1304CZ). This channel drives its own dedicated brushless motor (motor 4) and controls the brakes of motors 3 and 4.
The HSEBU (401CH) back-up channel is powered by power source E4 and receives input signals from the back-up box
and the HSSU (201CH) limit switches. This channel drives its own dedicated brush motor (back-up motor) and controls its
own dedicated brake.
Automatic Safety Loop (Aircraft with SB 211 but without SB 214 or M1245)
− ACMUs are provided with the HS position sensed by the HSSU and compare it to the commanded position
− In case of command/position mismatch, ACMUs will:
• Successively shutdown E3 and E4 electrical power within a 1”-period, stopping any trim runaway
• Enable the HSEBU line to take precedence on the HSTA
• Allow the crew to use the manual pitch through the Backup Motor

been selected for this task as they provide an efficient and reliable method of achieving a large change in transmission
The Power Drive Unit contains the following sub-assemblies:
angle.
Hydraulic Motor
The hydraulic motor operates in response to hydraulic supply via the direction valve and provides torque into the PDU
gearbox. The hydraulic motor is a fixed displacement cartridge-type motor.
Motor Brake
The motor brake operates in response to hydraulic signals from the brake solenoid valve to allow system movement when
required. The brake is a pressure-off, friction plate device that has been designed to restrain the system against the full
force of the motor in the worst-case load conditions. The motor brake and brake solenoid unit is manufactured as a
separate block from the main PDU housing, so that there is no possibility of a crack in the housing that connects supply to
both the motor and brake simultaneously.
Gearbox
The PDU gearbox transmits torque from the hydraulic motor into the transmission system to extend or retract the flaps as
commanded by the pilot. The gearbox comprises of a spur-gear train with an appropriate ratio to provide the required
speed and torque to the transmission shafts.
Restrictors
A flow Restrictor has been incorporated into the control line to limit the speed of the PDU motor.
Transmission Shafting
The flap transmission shafts transmit torque from the flaps power drive unit (3002CF) through the gearboxes to the
actuators.
The shafts are held by the gearboxes and the flap transmission actuators. Where the distance between gearboxes or
actuators is too long for a single shaft, more than one shaft is used. Where more than one shaft is used steady bearings
are used to hold the shaft. Splined universal joints are installed on the ends to connect to adjacent components. Where a
shaft connects to an actuator or gearbox one end of the shaft is telescopic for removal.
The LH upper 90° flap gearbox (L3502CF) (RH upper 90° flap gearbox (R3502CF) for RH) transmit the torque from flap
transmission shaft 1 which is horizontal to flap transmission shaft 2 which is vertical. The LH lower 90° flap gearbox
(L3602CF) (RH lower 90° flap gearbox (R3602CF) for RH) transmit the torque from flap transmission shaft 2 which is
vertical to flap transmission shaft 3 which is horizontal.

Components (Continued)
Ballscrew Actuators (L7003CF/R7003CF/L7103CF/R7103CF/L7203CF/R2003CF/L7403CF/R7403CF)
The actuator extends rearward to extend the flaps and retracts forward to retract the flaps. In the retracted position the
ballscrew is contained in a recess in the fuel tank. Each actuator is attached to the rear spar of the wing by a gimbal. A
ballscrew is connected to the flap with a spherical bearing. Input from the transmission system is from a spline on the
inboard side. A spline on the outboard side transmits the torque to the outboard shaft of the transmission system.
A worm-wheel gear changes the torque of the transmission shaft into the linear movement of the ballscrew. The actuator
includes a no-back assembly which prevents backdriving of the actuator by the aerodynamic forces.
Depending on the direction of rotation of the transmission shafts, the ballscrew is moved either rearward through the body
of the actuator to extend the flap, or forward to retract the flaps. Clawstops on the rear face of the actuator and the
forward end of the ballscrew prevent ballscrew extension beyond its limits if the system malfunctions.
Each actuator also includes a shear pin between the actuator input and the ballscrew nut. The shearpin limits torque
transmission through the actuator, in the event of a jam. If too much torque is transmitted through the actuator the
shearpin breaks.
Position Sensors
Each flap surface is connected by a cable to a flap position sensor that includes a dual potentiometer, gears, capstan and
housing. The signal from the potentiometer changes if the flap and cable moves. Two sensors are installed on each wing.
The inboard sensor is connected to the inboard flap and the outboard sensor is connected to the outboard flap. The
inboard sensors on each wing are installed between actuators 1 and 2. The outboard sensors are installed outboard of
actuator number 4. Each position sensor is connected to the related flap by a spring-loaded cable. An additional inboard
sensor is installed on the LH wing, next to actuator 1.
Each inboard sensor supplies two channels of flap position indication from two continuous potentiometers:
− Channel number 1 goes to the SFAU (9001CF) and is used to sense when the inboard flaps are not synchronized,
− Channel number 2 goes directly to the primary flight control system for use in the slat and airbrake control logic.
The additional inboard sensor on the LH wing supplies two channels of flap position indication from two continuous
potentiometers directly to the primary flight control system for use in the slat and airbrake control logic. Each outboard
sensor supplies one channel of flap position indication from a continuous potentiometer to the SFAU (9001CF) and is
used to sense when the outboard flaps are not synchronized.
Flap position data is transmitted by the primary flight control system to the avionics system to give flap position indication
for the flight crew. Flap position indication is then transmitted by the avionics system to the flight data recorder and to the
central maintenance computer. The central maintenance computer uses the flap position data for isolation of flap control
system faults.
The left hand inboard position sensor contains two switched track potentiometers also moved by the reduction gears. The
switched track potentiometers make a discrete signal for each of the flap positions.
Operation
As the flap surface moves a spring-loaded capstan in the position sensor is moved by a cable connected to the flap
surface. The capstan moves the potentiometer through the reduction gear. The potentiometer gives an electrical signal to
the SFAU (9001CF) or to the primary flight control system that changes in proportion to the quantity of movement of the
flap surface.

Slat / Flap and Airbrake Unit (9001CF) The SFAU checks the operation of the PDU motor brake on receipt of a Flap Brake & Airbrake Lock Test signal from the

providing that no movement is seen and the SFAU Flap Fault is generated during the test.
When movement is commanded, there is a short time delay before the energization of the extend or retract solenoids to
ensure that the brake is normally released whilst the system is static. When the commanded position is reached there is a
short delay before the de-energization of the brake solenoid to ensure that the brake re-engages when the system has
become static.
If the flap system continues to move beyond the commanded position (outside of normal tolerances) the SFAU will
energies the de-energized direction control solenoid (for example if the system is extending past its commanded position,
the retract solenoid will be energized). Energization of both direction control solenoids is detected as a fault condition, and
the SFAU will de-energies the brake release solenoid.
In the event that the system starts to move in a direction opposite to that commanded, due to a jammed direction control
valve in the PDU, an incorrect movement fault is detected and the SFAU will de-energies the extend, retract and brake
release solenoids so that the system is arrested and held stationary. A “SFAU Flap Fault” signal is sent to the avionics
system so that the “Flap Fault” caution is raised to alert the crew that a failure has occurred.
The SFAU compares the signals from Channel 1 of each of the four flap position sensors and generates an “Asymmetry
Fault” if the LH Inboard does not agree with the RH Inboard, or if the LH Outboard does not agree with the RH Outboard,
outside of normal tolerance. To avoid untimely detection due to wing bending when the flaps are fully extended, the
asymmetry monitoring is inhibited when the flaps are in steady extended 40° position The two independent control signals
from the slat/flap control lever are compared inherently, in that an incorrect control signal from one of the lever sensors
will result in both extend and retract solenoids being energized, and the generation of a “SFAU Flap Fault”.
When flap movement is commanded a command from the SFAU to the brake solenoid operates the brake pistons and
disengages the friction plates. When the flap movement commanded is to deploy the flaps, a command from the SFAU to
the extend solenoid valve pilots pressure to shuttle the direction valve so that hydraulic supply pressure is supplied to the
motor extend chamber and the motor retract chamber is connected to return. This allows the motor to extend the flap via
the gearbox and transmission system.
In the same way, when the flap movement commanded is to retract the flaps, a command from the SFAU to the retract
solenoid shuttles the direction valve to connect supply to the retract chamber and to connect the extend chamber to return
so that the motor is allowed to retract the flap. If both solenoid valves are powered the direction valve will be held in the
neutral position so that the system does not move.

AIRBRAKE CONTROL SYSTEM
Overview This provides each actuator with two means to be held in the retracted position. The actuators are extended by supplying
hydraulic pressure to locking port and to the “Uext” port to the extension area (larger area). The actuators have no locking
The airbrake system is designed to provide aerodynamic braking to the aircraft. There are two externally hinged airbrake

panels (outboard, inboard) on each wing:
− For the left wing, the LH inboard airbrake (L9500CD) and the LH outboard airbrake (L9501CD)
The airbrake actuators are held in the extended or retracted position by the hydraulic pressure permanently supplied in

the retraction area by the airbrake control manifold (202CD). Due to the differential section, the force in the extension area
is stronger than the force in the retraction area. When the hydraulic pressure is supplied to the extension area, the piston

Extension and retraction of the airbrake panels is controlled manually by the airbrake lever in the flight compartment and
automatically by the braking system, the primary flight control system and the Slats Flap and Airbrakes Unit SFAU
(9001CF). The airbrake system is held in the fully retracted position even after a loss of hydraulic power.
The two-position hydraulic actuators actuate each inboard and outboard airbrake panels and are attached on the wing
trailing edge on the other side.
Components
Inboard and Outboard Airbrake Actuators (L802CD/R802CE) (L1002CD/R1002CD)
It is composed of a cylinder body, a piston rod and three hydraulic ports:
− The cylinder body is fitted on the aircraft wing by four attachment screws
− The piston rod is fitted with a stirrup assembly which is attached to the airbrake panel
− The hydraulic ports provide the hydraulic fluid from the Hydraulic System to the retraction line, extension line, locking
line
The airbrake actuators are used to extend, retract and maintain in the retracted position the airbrake panels. These
hydraulic actuators have an unbalanced piston area with retraction area (smaller area) which is permanently supplied (by
the “Uret” port - “RET” port on the actuators) if the hydraulic system is pressurized. It forces the actuators in the retracted
position when the extension area is not supplied.
The actuators also have a mechanical locking device which hold the piston rods in the retracted position. The lock is
composed of four radial lock-keys which are held in position by a lock-piston. A spring holds the lock-piston in rest position
(piston rod locked). To unlock the piston rod, the lock-piston is moved when hydraulic pressure is applied through the
“Ulock” port. This allows the lock-keys to move radially which unlocks the piston rod.

AIRBRAKE CONTROL SYSTEM (CONTINUED)
Components (Continued) Operation
Airbrake Control Manifold (2002CD) When the airbrake panels are retracted, they press on sensor microswitches, the signal sent is then a high impedance
which means “PANEL RETRACTED”.
It supplies hydraulic pressure to the mechanical locks, the extension and the retraction areas of the airbrake actuators. It
is electrically commanded and it pilots the pressure sent to the airbrake actuators by the means of solenoid valves. It is
composed of : When the airbrake panels leave the retracted position, the microswitches are released, the signal sent is then a ground
− Two electrical connectors (one for the two lock solenoids and one for the two extension solenoids), level which means “PANEL NOT RETRACTED”.
− One filter (class 10 contamination fluid),
− Two lock solenoid electro-valves (EV2, EV4) to supply pressure to the unlocking port of the actuators (one for the
inboard actuators, one for the outboard actuators),
− Two extend solenoid electro-valves (EV1, EV3) to actuate the spool valves (one for the inboard actuators, one for the
outboard actuators) supplying pressure to the extension areas of the actuators.
When the airbrake control manifold (202CD) is not energized, each solenoid valve is in the closed position (lock piston or
extension area to the return pressure line). Moreover, the airbrake control manifold (202CD) has 7 hydraulic ports:
− Pressure (hydraulic system B) − Inboard Retraction Circuit
− Return (hydraulic system B) − Outboard Retraction Circuit
− Inboard Extension Circuit − Retraction Circuit
− Outboard Extension Circuit
The airbrake control manifold (202CD) is fitted on the aircraft structure by 4 screws.
Operation
Refer to the figure to locate the ports quoted in the text. The ports between brackets are those written directly on the
equipment.
When the airbrakes are retracted, the solenoid valves are not energized. Thus, the hydraulic pressure is supplied to the
airbrake actuator retraction areas through their “Ur” port (“RET” port on the actuators) by the “Po” port (U5 port on the
ACM) of the airbrake control manifold (202CD). Outboard and inboard extension and locking areas are connected to the
return pressure through respectively “Uo” (“EXT” port on the outboard actuator), “Ui” (“EXT” port on the inboard actuator),
“Uop” (“UNL” port on the outboard actuator) and Uip” ports (“UNL” port on the inboard actuator).
When the airbrakes are commanded to extend, the signal is transmitted to the SFAU (9001CF) which send the signals to
the airbrake control manifold (202CD).
When airbrake extension is commanded, the EV2 and EV4 are first energized. This unlocks the piston rod. After a time
delay of 300 ms, the EV1 and EV3 are energized which extend the airbrake panels. This time delay ensures that the
piston rod will be unlocked before extension is commanded for all temperature conditions.
The microswitches are in rest position when the airbrake panels are extended.

AIRBRAKE CONTROL SYSTEM (CONTINUED)
Operation
Extension / Retraction in Normal Mode
The airbrake lever has three positions (“AB 0”, “AB 1” and “AB 2”) from the forward to the rear :
− In the “AB 0” position, all airbrakes and spoilers are retracted
− Between the ”AB 0” and the “AB 1” positions, spoilers are partially (proportionally) extended
− In the “AB 1” position, the spoilers are fully extended
− In the “AB 2” position, in flight and if the flaps are retracted, the inboard and outboard airbrakes and the spoilers are
extended
− In the “AB 2” position, in flight and if the flaps are not retracted, the outboard airbrakes and the spoilers are extended
− In the “AB 2” position, on ground, the inboard and outboard airbrakes and the spoilers are extended

Airbrakes – Automatic Extension on Ground at Landing and RTO

AIRBRAKE CONTROL SYSTEM (CONTINUED)
Operation (Continued)
Extension / Retraction in Automatic Mode
There are four automatic functions:
− An automatic extension on ground at landing and Rejected Take Off (RTO)
− An automatic retraction for stall protection
− An automatic retraction in case of go-around
− An automatic retraction of inboard airbrakes in flight with flaps not retracted, managed by the Primary Flight Control
System (PFCS)
The result of these is the “autoretract” or “autodeploy” commands. These commands are transmitted to the SFAU
(9001CF).
NOTE: For the spoilers, the command is transmitted directly by the PFCS and the ACMU.
These functions are distributed over the SFCI 3 module (502CZ) (copilot control) and the SFCI 4 module (402CZ) (pilot
control) and ensure the following actions, based on orders transmitted by the MFCCs:
− A/B autodeploy
− A/B autoretract
These orders are sent to the SFAU channels for airbrake actuation.
NOTE: For the spoilers, the Spoiler Control in the PFCS receives all "autodeploy" orders from both SFCI 3
module (502CZ) and SFCI 4 module (402CZ), and directly send order to the ACMU for spoiler actuation.
The dual SFCI architecture provides the proper availability of the automatic extension function.

Automatic Retraction Architecture
Each SFCI 3 module (502CZ) and SFCI 4 module (402CZ) elaborates two "autoretract" orders, one acting on the Inboard
airbrakes, and one acting on the Spoiler and Outboard airbrakes.
Inboard Airbrakes
Inboard Airbrake "autoretract" order from SFCI 4 module (402CZ) acts on Inboard Airbrake lock solenoid, and will
therefore inhibit inboard airbrakes extension when active.
Inboard Airbrake "autoretract" order from SFCI 3 module (502CZ) acts on Inboard Airbrake extend solenoid, and will
therefore retract the inboard airbrakes and inhibit their extension when active.
NOTE: When airbrakes are automatically retracted, the airbrakes will not re-extend when the autoretract
conditions disappear. The pilot first has to confirm the retraction by returning the control handle to “AB 0”
before extension is achievable.
In addition, the two inboard airbrake "autoretract" signals are activated in flight with flaps not retracted for aircraft
flaps/airbrakes aerodynamic configuration management.

SLAT CONTROL SYSTEM
Overview The Normal actuators are powered by hydraulic A and controlled through E3 power supply.
The aircraft is fitted with three slats on each wing:
− LH Inboard Slat (L9500CM) and the RH Inboard Slat (R9500CM) The Back-up actuators are powered by hydraulic B and controlled through E4 power supply.
− LH Middle Slat (L9501CM) and the RH Middle Slat (R9501CM)
− LH Outboard Slat (L9502CM) and the RH Outboard Slat (R9502CM)
The actuators and the microswitches are located on front spar wings whereas the SCM is located in a fuselage fairing.
The Slats Flaps and Airbrake Unit (SFAU) (9001CF) is located on the pedestal. The slats control system does the
functions that follow:
− Actuation of the six slats with:
• Normal pilot order
• Back-up pilot order (applicable to middle and outboard slats)
• Automatic order
− Position holding of the six slats
− Monitoring of the position of the six slats

SLAT CONTROL SYSTEM (CONTINUED)
Components (Continued)
Slat Control Manifold (SCM)(101CM)
The SCM (101CM) provides the hydraulic control for six normal actuators (inboard, middle and outboard) and four back-
up actuators (middle and outboard). The SCM (101CM) is divided into two parts, one powered by hydraulic System A
(normal control) and the other powered by hydraulic system B (back-up control).
Hydraulic system B pressure can only rise on SCM PRESS B port after hydraulic system A pressure has already risen on
SCM PRESS A port. Thus, the inboard slats always retract before the middle and outboard slats. If, after a failure,
hydraulic system A does not supply SCM any more, then hydraulic system B continues to supply SCM due to internal
hydraulically self maintaining.
When hydraulic system A raises over 150 bars (2,176 PSI), a plunger compress a spring and pushes the spool, thus
hydraulic system B can flows to PRESS B SCM. In this position hydraulic system B also acts on the spool in order to
ensure a self maintaining.
In case of hydraulic system A loss, PRESS B SCM will remain connected to hydraulic system B even if hydraulic system
B decreases to a pressure equal 15 bars (217.6 PSI). Under this value, an internal spring will set the spool to its rest
position which connects PRESS B SCM to return.
The slat supply selector (1701CM) is located under the fuselage forward fairing (133AL).

SLAT CONTROL SYSTEM (CONTINUED)
Components (Continued)
Slat Hooks
When retracted, the middle and outboard slats are held back at each end by a slat hook in order to adapt the slat shape to
the bent wing profile. The slat hooks are fed by the hydraulic system B. Unlocking is fed on the same line as extension of
the back-up actuators, and locking is fed on the same line as retraction of the back-up actuators.
The flow to the retraction chamber is reduced by a nozzle. Thus, despite being fed simultaneously with the retraction Slat Hook Installation
chambers of the slat actuators, the slat hook fully lock after the slats are retracted. A back pressure spring valve set in
parallel with the nozzle allows the unlocking time of the slat hook to be as short as possible.
To prevent possible jamming of the rod inside the bearing, a wear pin is fitted between the piston rod and the dog support.
Secondary Flight Control Interface, SFCI 3 Module (502CZ) and SFCI 4 Module (402CZ)
Each SFCI includes two hardware lanes A & B and performs the following functions:
− Transmits commands to coils B1, B2, B31 of the SCM
− Receives the automatic commands, the flap "retracted" information and the manual slat extension enable signal from
the PFCS
− Receives information from all the slat position microswitches
− Supplies the positions of the slats to the PFCS
− Receives the normal pilot command from the SFAU
− Transmits the middle and outboard slat "extended" information to the SFAU
The SFCI 3 module (502CZ) module controls the middle/outboard slat normal actuators and the inboard slat actuators via
the E3 power source, The SFCI 4 module (402CZ) module controls the middle/outboard slat back-up actuators via the E4
power source.

Pilot Normal Extension
Coil B1 is energized through the SFCI 3 module (502CZ) and, simultaneously, coil B31 is energized through the SFCI 4
module (402CZ), causing the HP to be applied to the extension chambers of the middle and outboard normal and back-up
actuators, and the Low Pressure (LP) to the retraction chambers and slat hooks. The middle and outboard slats extend,
powered by both the normal and back-up actuators.
When all four middle and outboard slats are fully extended (information from the microswitches), coil B2 is energized
through the SFCI 3 module (502CZ), causing the HP to be applied to the extension chambers of the inboard actuators.
The HP remains applied to the retraction chambers of the inboard actuators.
The middle and outboard slats retract, powered by both the normal and back-up actuators. After a time delay greater than
the slat retraction time, the slat hooks lock.

FUEL SYSTEM
Overview It sends the information to the Enhanced Avionics System (EASy) that displays the associated indication in the cockpit.
The function of the fuel system is to contain and supply the fuel for the three engines and the Auxiliary Power Unit (APU).
The fuel system includes the subsystems that follow: The measurement, calculation and monitoring are mainly made by the Fuel Quantity Management Computer (FQMC)
(208QJ). However, in order to avoid a complete loss of fuel indication in case of total FQMC (208QJ) failure, the 1000 lbs
level detection is made by an independent system including dedicated level sensors connected to the Fuel Level Control
Storage System
Unit (FLCU) (308QJ).
The storage system includes three structural tank groups:

and the APU
RH Tank Group Includes the three RH wing tanks (inboard, middle and outboard), the RH front tank, the RH
center-wing tank and the RH feeder tank, to supply the engine 3 A total or partial refueling is done with controls and indications located on the refueling control panel (108QJ), without any
access to the cockpit, in the stand-by procedure, through the LH gravity refueling plug (L101QS) and the RH gravity
refueling plug (R101QS) located on the upper surface of each wing.
The aircraft has a total fuel capacity of 31,940 lbs with:
− LH Tank Group: 10,522 lbs
Draining and Defueling Systems
− Center Tank Group: 10,895 lbs
The draining system is used to evacuate the accumulated water and to bleed the fuel through nine drain valves
− RH Tank Groups: 10,552 lbs ((L202QV)/(R202QV)/(502QV)/(602QV)/(702QV)/(L702QV)/(R702QV)/(802QV)/(1002QV)) located at the lower part of
each fuel tank. The defueling system is used for the partial or complete defueling of any of the tank groups. Two defueling

Pressure (LP) air bled from the engines 1 and 3.
Distribution System
The distribution system includes:
− Fuel supply to the three engines and the APU
− Fuel transfer from one tank group to another one
Each tank group has a feeder tank with two booster pumps, one normal ((L106QD) / (M106QD) / (R106QD)) and one
stand-by ((L206QD) / (M206QD) / (R206QD)) which operates if the normal one is unserviceable, that supply fuel to the
related engine or APU.
The feeder tanks are permanently supplied with fuel sucked out from the other tanks of the related group through 13 jet
pumps ((L108QD) / (R108QD) / (L208QD) / (R208QD) / (L308QD) / (R308QD) / (L408QD) / (R408QD) / (L508QD) /
(R508QD) / (608QD) / (708QD) / (808QD)) which are supplied by the booster pumps.
To keep the fuel supply performance even in case of multiple failures, the fuel supply system lets any of the three tank
groups supply any of the three engines or the APU.
To keep the fuel balance in these multiple failure situations, or to quickly empty a fuel tank during maintenance
procedures, the fuel transfer system lets a direct fuel transfer from any tank group to any other one.
Indicating System
The indicating system is used for:
− Measurement, calculation and monitoring of the fuel quantities
− Fuel Center of Gravity (CG) Monitoring
− Fuel Level Monitoring
− Fuel Temperature Monitoring Figure 3

Fuselage Tanks The CTR center-wing tank is located between frames 20 and 26 and between left fuselage rib 2 and right fuselage rib 2. It
communicates only with the rear tank:
The fuselage tanks consist of:
− At the top of the tank through two pipes
− Front tank between frames 16 and 19
− At the bottom of the tank through one pipe
− Center-wing tank between frames 20 and 26
− Rear tank between frames 27 and 33

Ventilation around the Fuselage Tanks
The structural walls of the fuselage tanks on the boundary of the pressurized area are ventilated to vent any possible fuel
LH/RH Center-Wing Tank Assemblies vapor. There are two types of ventilation around the fuselage tanks:
Each LH/RH center-wing tank assembly is limited by the junction plate and the fuselage rib 2. − Area between the cabin floors and the walls of the fuselage tanks is ventilated by conditioning air
− Area between the walls of the fuselage tanks and the karmans is ventilated by outside air, taken at the level of air
The LH/RH center-wing tank assembly is divided into two compartments: inlets located between frames 16 and 20 and exhausted through air outlets located between frames 27 and 33
− LH/RH Center-Wing Tank
− LH/RH Feeder Tank
Each LH/RH feeder tank is divided into two sub-compartments. These two sub-compartments communicate by holes
located at the bottom of the boundary fitted with flapper valves in the direction of the booster pumps.
Upstream of each booster pump, a half height partition prevents the risk of draining during strong nose down attitudes and
introducing any air into the system.

FUEL TANK PRESSURIZATION SYSTEM
Overview
The purpose of the fuel tank pressurization circuit is to ensure correct operation, in the event of pumps failure. The
engines can still be supplied with a correct fuel pressure in case of pumps failure. Moreover, it limits the fuel vaporization
at high altitude.
The tanks are pressurized by air bled from engines 1 and 3. The tanks are equipped with relief valves, in order to avoid
any damage in case of overpressure or under-pressure in the pressurization system. The pressurization system:
− Maintains fuel tanks pressure within operating limits in order to ensure correct fuel supply to the engines in case of
booster pump failure, and to limit fuel vaporization
− Prevents against overpressure in the tanks
− Prevents against under pressure in the tanks
− Filters pressurizing air against contamination coming from the engines
− Avoids fuel overflow during ground operation or in the fuel pressurization pipe during flight
− Allows the de-pressurization of the fuel tanks during ground operation
− Allows a good venting of the outer wing tank when the aircraft is on ground with booster pumps off and tanks full
− Drains the fuel that may remain in the pressurization system

Components
Pressurization Filters
The aircraft has two pressurization filters:
− Engine 1 Pressurization Filter (403QP)
− Engine 3 Pressurization Filter (503QP)
The pressurization filters protect the air flow against contamination coming from the engines.
Check Valves
The aircraft has two check valves:
− Engine 1 Check Valve (203QP)
− Engine 3 Check Valve (303QP)
The check valve is composed of a main body with inlet and outlet ports, a poppet valve guide, a poppet valve and a spring
to hold the poppet valve in closed position. The body, the poppet and the guide are made of aluminum alloy. The spring is
made of stainless steel.
The check valves prevent the air or fuel back flows from the downstream circuit to the engines. The opening pressure is
15 hPa maximum.
The filter is used to filter dusts and to supply a dustproof air to the pressure reducing valve. The membrane and the spring
open the valve according to the pressure in the system. This valve performs different functions:
− Non-return valve, to prevent air or fuel flow from the downstream circuit to the engines,
− Pressure relief valve, to evacuate the overpressure directly to the outside. The threshold of this valve is set to
330 hPa.
The pressure reducing valve is connected directly to the tanks by two pressurization lines.

Components (Continued)
Valve Boxes
The aircraft has two valve boxes:
− Valve Box 1 (302QP)
− Valve Box 2 (402QP)
The valve boxes are used to protect fuel tanks from overpressure and under-pressure. Each valve box is made up of a
negative pressure relief valve and a pressure relief valve. They are directly linked to the high points of the loop pipes
through a line, then to the wing tanks through another line. The valve outlets are fitted with a flame arrester mesh in order
to protect the system against the direct effects of lightning strike.
The pressure relief valves open at 240 (+15/-0) hPa, and they can evacuate 3 kg/min at 300 hPa. Consequently, these
valves can drain off air from the tanks in order to prevent abnormal structural loads, in any configuration. In the case of a
pressure drop, the negative pressure relief valve opens at a value of 5 hPa.
The automatic drain valves are installed at low points of fuel pressure lines. They drain the pressurization lines on ground,
when the fuel system is not pressurized, in order to avoid water or fuel accumulations in the lines.
The automatic drain valves automatically drain the system through a 4 mm diameter hole, when the system is not
pressurized. They close automatically if the pressure is greater than 70 hPa.
Fuel Pressurization Coupling (9500QP)
Pressurization Manometer (508QJ)
The pressurization manometer (508QJ) displays the pressure in the pressurization pipes downstream of the pressure
reducer (202QP). It consists of a HP Bourdon tube-type gauge with a pointer on its face. The pointer has a 4% class
accuracy and moves from 0 to 5 psi with 0.2 psi graduations. The gauge has a green arc from 2.8 to 3.4 psi.
This valve is used to supply the wing tank with air, in case of negative pressure in the wing.
The wing vacuum relief valves are located at the wing tips. They open at the negative value of 20 (+4/-3) hPa.

FUEL TANK PRESSURIZATION SYSTEM (CONTINUED)
Components (Continued) The body of the jet pump has an injector. When a fuel pressure is applied in this injector, a negative pressure is created at
the entrance of the jet pump. This negative pressure creates a fuel flow which opens the check valves of the jet pump.
Wing Pressurization Valves
The fuel is then sucked, which drains the wing pressurization pipe.
The aircraft has two wing pressurization valves:
− LH Wing Pressurization Valve (L803QP)
− RH Wing Pressurization Valve (R803QP)
The wing pressurization valves are electrically-operated by a motor equipped with a manual control lever. In the open
position, they allow the venting of the wing tanks during refueling. On the ground, they enable the pressure balance
between the front and wing tanks.
In closed position, they separate the wing pressurization lines from the ones coming from the engines in case of any fuel
overflow of the wing tank during the flight.
The front tank PCB (408QJ) controls the two wing pressurization valves opening when the aircraft is on ground and the
booster pumps are off (LH/RH, Normal and Stand-by).
Both pressurization valves will stay open until these two last conditions are verified and must be closed in flight conditions.
They can also be manually controlled. Both pressurization valves need to be open to proceed to the fueling operation.
Vent Valves
The aircraft has three vent valves:
− LH Vent Valve (L703QP)
− CTR Vent Valve (603QP)
− RH Vent Valve (R703QP)
The vent valves are composed of a main body with one ball type valve operated by a single motor actuator. They can be
controlled electrically by the motor or manually by a control lever.
Two valves are located in the wings, in front of the tanks. Theses valves are installed in high points on the vent line.
Therefore, there is no possibility of water, fuel or dust accumulations. The third vent valve is located on pressurization
pipes, close to the valves boxes.
In closed position, these vent valves isolate the tanks from the outside, to allow the tank pressurization. When open, they
permit the tank depressurization (communication between tanks and external atmosphere) for refueling or defueling
operations.
The vent valves are controlled electrically, through the venting PCB (103QP), by the refueling coupling lever microswitch
(111QS) linked to the refueling coupling lever (9500QS). The vent valves have to be opened to proceed to the refueling or
defueling operations. For dispatch in case of actuator failure, they can also be manually controlled.
The LH / RH jet pump bleeds the LH / RH wing pressurization pipe to avoid any fuel to remain in the pressurization lines.
The jet pumps operate according to the venturi principle by using the motive fuel flow delivered from the booster pumps
via the injector manifolds.

FUEL TANK PRESSURIZATION SYSTEM (CONTINUED)
Operation
The lateral engine bleed air lines are routed to the engine fire wall via the upper part of the nacelle. The isolation of the
engine fire wall is performed by two Detampel fittings. Two diaphragms, located in the pylon area, reduce the air flow
down to 0.75 kg/min, whatever the conditions.
Then, the air reaches a common air manifold through a non-return valve and a filter. The threshold of the non-return valve
is of 15 hPa and the filter is made up of a mesh of 40 µm, which supplies a dustproof air towards the pressure reducer
(202QP).
The overpressure evacuation and the pressurization of the tanks are continually carried out, in order to be sure to have
the same level of pressurization everywhere.
The CTR center-wing tank is directly connected to the pressure reducer (202QP) by a line. The rear tank is pressurized by
an overflow pipe connected to the CTR center-wing tank.
The LH and RH front tanks are directly connected to the pressure reducer (202QP) by a pressurization line.
The LH / RH wing tanks are first pressurized by a pipe running from the LH / RH front tank to the LH / RH wing outboard
tank. This pipe is drained by the LH / RH pressurization pipe jet pump (L908QD) / (R908QD). They are also pressurized
through two holes, with a diameter of 45 mm, located in the junction plates.
Whatever the aircraft attitude, the high points of the lines (thanks to the loop pipes) and the wing pressurization valves
avoid the risk of siphon backing-up through the pressurization circuit and the jet pumps suck fuel which could be in the low
points of the pressurization circuit.

DISTRIBUTION SYSTEM
Overview
The distribution system:
− Supplies the engine 1, 2 and 3 and the APU with fuel bled from their respective tank group:
• LH tank group supplies the engine 1
• Center tank group supplies the engine 2 and the APU
• RH tank group supplies the engine 3
− Allows the fuel shut-off valves activation on the fuel supply lines in case of potential fire of one engine or APU
− Allows the feeding of any engine or the APU from any of the other tank groups (crossfeed) in case of failure of the
feeding from its respective tank group
− Allows the fuel transfer between any of the three tank groups (crosstank)
Each engine is directly and independently supplied with fuel by two Booster Pumps (BP), installed in the feeder tank: a
normal BP and a stand-by BP.

DISTRIBUTION SYSTEM (CONTINUED)
Components The normal and stand-by booster pumps 1 / 3 are used to transfer the fuel from the LH / RH tank group to the LH / RH
crossfeed units. The normal and stand-by booster pumps 2 are used to transfer the fuel from the center tank group to the
Jet Pumps
BP 2 manifold fuel transfer valve.
The aircraft has a total of 13 jet pumps:
− LH Wing Inboard Tank Jet Pump (L108QD) − CTR Tank RH Jet Pump (R408QD)
The booster pumps are electrically controlled, through the X-TK/X-BP normal 2 PCB (803QD), by the pushbuttons
− RH Wing Inboard Tank Jet Pump (R108QD) − LH Feeder Tank Jet Pump (L508QD) installed on the overhead panel (5000PM):
− LH Wing Middle Tank Jet Pump (L208QD) − RH Feeder Tank Jet Pump (R508QD) − X-TK 1-2 Pushbutton (L9850PM)
− RH Wing Middle Tank Jet Pump (R208QD) − CTR Feeder Tank LH Jet Pump (608QD) − X-TK 2-1 Pushbutton (L9810PM)
− LH Wing Outboard Tank Jet Pump (L308QD) − CTR Feeder Tank RH Jet Pump (708QD) − X-TK 2-3 Pushbutton (L9830PM)
− RH Wing Outboard Tank Jet Pump (R308QD) − CTR Feeder Tank CTR Jet Pump (808QD) − X-TK 3-2 Pushbutton (L9870PM)
− CTR Tank LH Jet Pump (L408QD) − X-TK 1-3 Pushbutton (L9780PM)
− X-TK 3-1 Pushbutton (L9790PM)
The jet pumps ensure that the booster pumps remain always immersed in their feeder tank, by sucking the fuel from the
different tanks of the tank group. The jet pumps operate according to the venturi principle by using the motive fuel flow
delivered from the booster pumps via the injector manifolds.
The body of the jet pump has an injector. When a fuel pressure is applied in this injector, a negative pressure is created at
the entrance of the jet pump. This negative pressure creates a fuel flow which opens the check valves of the jet pump.
The fuel is then sucked and injected inside the feeder tank.
Booster Pumps
The aircraft has a total of six identical booster pumps mounted into canisters. There are two booster pumps per tank
group (one for normal operation, one for stand-by operation):
− Normal Booster Pump 1 (L106QD)
− Stand-By Booster Pump 1 (L206QD)
− Normal Booster Pump 2 (M106QD)
− Stand-By Booster Pump 2 (M206QD)
− Normal Booster Pump 3 (R106QD)
− Stand-By Booster Pump 3 (R206QD)
The booster pumps are used to prime the engine fuel supply lines. The booster pump pressure guarantees that the
engine will be correctly supplied during normal operation. The pumps are mounted vertically in a canister. Therefore, it is
possible to remove the pump without defueling the tank. The electronic circuit driving the motor includes a current limiting
device. The current limitation ensures that the fuel pump temperature will never reach more than 90°C (even in case of
dry run or rotor jamming).
Operation
− Normal Booster Pump 1 (L106QD) is controlled by the "BOOST 1" pushbutton (L9800PM) through the BP 1 relay
(L116QD)
− Normal Booster Pump 2 (M106QD) is controlled by the "BOOST 2" pushbutton (L9860PM) through the BP 2 relay

Booster Pump 2 Filter (104QD) In the crosstank mode the LH / RH crossfeed unit is open and allows the fuel supply from the booster pumps 1 / 3 to the
BP 1 / 3 manifold fuel transfer valve.
The booster pump 2 filter (104QD) is equipped with one main body which includes one filter, one slide valve, one piston
valve and one by-pass valve.
In the back-up crosstank mode, the solenoid valve (9670QD) of the LH crossfeed unit allows the back-up crosstank
modes between LH and RH tank groups by controlling the opening of the wing tank cross valve (XTK) (103QD). The

On ground, it is possible to clean or change the filter element without defueling the tank. The slide valve and the piston
valve close the inlet and outlet to prevent fuel draining.
Crossfeed Units
The aircraft has two crossfeed units:
− LH Crossfeed Unit (405QD) for the engine 1 circuit Booster Pump 2 Filter (104QD)
− RH Crossfeed Unit (505QD) for the engine 3 circuit
The RH crossfeed unit is equipped with one main body which includes one ball valve operated by a motor or a manual
lever, one filter and one check valve. This actuator can be removed without removing the crossfeed unit. The filter avoids
foreign particles ingestion able to obstruct the jets pumps. The check valve allows filter removal without draining the tank
group.
In the back-up crossfeed mode, the crossfeed unit switches the fuel pressure from RH injector manifold to the LH
crossfeed unit (405QD) or from LH injector manifold to the RH crossfeed unit (505QD) in case of failure of the BP 1
manifold fuel transfer valve (9631QD) or respectively BP 3 manifold fuel transfer valve (9651QD).
The back-up crossfeed mode is controlled by the "BACKUP 1-3" pushbutton (L9820PM) and the "X-BP 1-3" pushbutton
(L9890PM) installed on the overhead panel (5000PM) through the X-TK/X-BP stand-by PCB (703QD).

Booster Pump Manifolds In the crosstank mode the respective fuel transfer valve is open and allows the fuel supply from the respective BP
manifold fuel transfer valve to the defueling manifold transfer valve (9500QV).
The aircraft has three booster pump manifolds (one per circuit):
− Booster Pump 1 Manifold (105QD)
The actuator is electrically controlled, through the X-TK/X-BP normal 1 PCB (603QD) and X-TK/X-BP normal 2 PCB
− Booster Pump 2 Manifold (205QD)
(803QD), by the pushbuttons installed on the overhead panel (5000PM):
− Booster Pump 3 Manifold (305QD)
− X-TK 1-2 Pushbutton (L9850PM)
− X-TK 2-1 Pushbutton (L9810PM)
The booster pump manifold (105QD) / (205QD) / (305QD) is the link between the boost pumps, the fuel supply line of the
− X-TK 2-3 Pushbutton (L9830PM)
engine and the APU, and the transfer / defueling line of the defueling manifold (101QV). Each booster pump manifold
(105QD) / (205QD) / (305QD) is equipped with one main body which includes two valves and one check valve. − X-TK 3-2 Pushbutton (L9870PM)
− X-TK 1-3 Pushbutton (L9780PM)
These two valves are: − X-TK 3-1 Pushbutton (L9790PM)
− BP Manifold Fuel SOV (9630QD) / (9640QD) / (9650QD)
− BP Manifold Fuel Transfer Valve (9631QD) / (9641QD) / (9651QD)
These valve actuators can be removed without removing the booster pump manifold. The check valve avoids uncontrolled
fuel transfer back to the booster pumps. In addition, only booster pump 2 manifold (205QD) is fitted with a derivative line
to supply the APU.
BP3 Manifold (305QD)
The electrical power supply is dual and fully independent. One of the two motors is supplied directly with battery current.
The loss of one motor will not affect the operation of the valve supported by the other motor.
Once closed, the BP manifold fuel SOV allow thermal expansion through the valve of the fuel entrapped between the
valve and the engine.
For the crossfeed modes, the actuator is electrically controlled, through the X-TK/X-BP normal 1 PCB (603QD) and X-
TK/X-BP normal 2 PCB (803QD), by the pushbuttons installed on the overhead panel (5000PM):
− "X-BP 1-2" Pushbutton (L9880PM)

Booster Pump 2 / APU Cross Valve (302QD)
The booster pump 2 / APU cross valve (302QD) supplies engine 2 either by the engine 2 fuel supply line (normal mode)
or by the APU fuel supply line (engine 2 back-up mode). It is equipped with one main body which includes one ball valve
operated by a motor or a manual lever.
In normal mode, the valve is in open position and the fuel comes from the engine 2 fuel supply line to the engine 2.
In engine 2 back-up mode, the valve is in closed position and the fuel comes from the APU fuel supply line to the engine
2. The engine 2 back-up mode is electrically controlled by the "FUEL 2 B/U" switch / light (412QD) installed on the
emergency switch box (1001FW).
The APU fuel SOV actuator (9680QD) is electrically controlled by the "MASTER" APU pushbutton (R9500PM) on the
overhead panel (5000PM) or the "FUEL 2 B/U" switch/light (412QD) on the emergency switch box (1001FW). In closed
position, the APU is no more supplied with fuel.
The electrical power supply is dual and fully independent. One of the two motors is supplied directly with battery current.
The loss of one motor will not affect the operation of the valve supported by the other motor.
Once closed, the APU fuel SOV (102QD) allow thermal expansion through the valve of the fuel entrapped between the
valve and the APU.
The wing tank cross valve (XTK) (103QD) is closed by spring action when there is no fuel pressure coming from the LH
crossfeed unit (405QD).
When the solenoid valve of the LH crossfeed unit (405QD) is electrically supplied, it allows the fuel pressure to reach the
wing tank cross valve (XTK) (103QD), behind the piston. Then, the pressure counterbalances the spring force and pushes
the piston in open position.

in the various tanks of the tank groups in the proper sequence. There are three normal crossfeed modes: X-BP 1-2, X-BP 2-3 and X-BP 1-3.
For the LH and RH tank groups, the emptying sequence of the tanks is as follows: X-BP 1-2 Mode
− LH/RH Front Tank The X-BP 1-2 mode is used to supply the engine 1 and 2:
− LH/RH Wing Outboard Tank − With fuel stored in the center tank group when the normal booster pump 1 (L106QD) and the stand-by booster pump

If there are fuel leaks on the engine 2 fuel supply line, the BP 2 manifold fuel SOV (9640QD) can be closed through the
"FIRE 2" switch / light (955WZ) on the fire panel (200WZ). If no other leak is detected on the center tank group and no fire
is detected on the engine 2, the "FUEL 2 B/U" switch / light (412QD) on the emergency switch box (1001FW) can be
pushed to control:
− APU fuel SOV (102QD) in the open position
− Switch of the booster pump 2 / APU cross valve (302QD) to supply fuel to the engine 2 through the APU fuel supply
line
As the engine 2 is supplied through the APU fuel supply line, the engine 2 can be restarted.

Overview Fuel Flow Indicating System
The fuel flow indicating system:
The indicating system:
− Measures the instantaneous fuel flow, for each engine
− Measures, calculates and monitors the fuel quantities
− Calculates the fuel used quantity, for each tank group
− Monitors the gauging accuracy
− Calculates the fuel gauged quantity, for each tank group
− Monitors the fuel Center of Gravity (CG)
− Calculates the total fuel used
− Monitors the fuel levels
− Sends the total fuel used to the Flight Management System (FMS) which computes the total fuel remaining
− Monitors the fuel temperature
− Sends the results to the EASy system that shows the associated indication in the cockpit
− Monitors the fuel flow rates
It sends the information to the Enhanced Avionics System (EASy) that shows the associated indication in the cockpit.
The Fuel Quantity Management Computer (FQMC) (208QJ) calculates monitors and sends the results to the EASy
system, for display in the cockpit.
To calculate accurately the fuel quantity held in each tank group, the FQMC (208QJ) uses the fuel height values received
from the fuel gauging probes. Then, the FQMC (208QJ) corrects these values by taking account the fuel density, the
aircraft attitude, the wing deflection (ground / flight) and the tank shape.
The primary components of the Fuel Quantity Monitoring System (FQMS) are:
− Fuel Quantity Management Computer (FQMC) (208QJ)
− Fuel Gauging Probes
− Fuel Density Sensors

Components The fuel gauging probes are made of two concentric tubes that make a capacitor. The two tubes are made of fiberglass
coated with synthetic resin, metallized with silver and varnished with synthetic resin again.
Fuel Quantity Management Computer (FQMC) (208QJ)
The FQMC (208QJ) calculates fuel quantities, monitors and sends the results to the EASy system, for display in the
cockpit. The capacitance between the active sections of the inner probe cylinder (high impedance) and of the outer probe cylinder
(low impedance), is proportional to the height of the probe being immersed in the fuel. This capacitance is read by the
FQMC (208QJ).
The FQMC (208QJ) includes two channels (channel 1 and channel 2) electrically and mechanically isolated that do the
same tasks. The FQMC (208QJ) channel 1 and channel 2 send data to the generic I/O 2 module (4201FY) and the
generic I/O 3 module (4301FY) through the ARINC 429 busses. The Data Acquisition System manages the decision of The fuel gauging probes that follow, which have a length below 400 mm, are free at their ends:
using the either the channel 1 or channel 2 information for display. − LH Wing Middle Tank Front Inboard Gauging Probe (L503QJ)
− RH Wing Middle Tank Front Inboard Gauging Probe (R503QJ)
The FQMC (208QJ) ensures: − LH Wing Middle Tank Outboard Gauging Probe (L603QJ)
− Fuel gauging probes and fuel density sensors excitation − RH Wing Middle Tank Outboard Gauging Probe (R603QJ)
− Fuel gauging probes and fuel density sensors analog signals acquisition − LH Wing Outboard Tank Outboard Gauging Probe (L703QJ)
− Fuel quantity calculation − RH Wing Outboard Tank Outboard Gauging Probe (R703QJ)
− Gauging accuracy monitoring − LH Wing Outboard Tank Inboard Gauging Probe (L803QJ)
− Fuel center of gravity monitoring − RH Wing Outboard Tank Inboard Gauging Probe (R803QJ)
Fuel Gauging Probes Others fuel gauging probes have a rubber connector end which fits into a centering guide. The fuel gauging probes are
The aircraft has a total of 26 fuel gauging probes: 12 located in the fuselage and 7 located in each wing. The fuselage fuel adjusted for the best accuracy by the manufacturer. No later adjustment is needed after installation in the aircraft.
gauging probes are:
− LH Center-Wing Tank Gauging Probe (L903QJ) − CTR Center-Wing Tank Rear Gauging Probe (1203QJ) Fuel Density Sensors
− RH Center-Wing Tank Gauging Probe (R903QJ) − Rear Tank RH Front Gauging Probe (1303QJ) The aircraft has a total of two fuel density sensors, which are integral part of the two fuel gauging probes that follow:
− LH Feeder Tank Gauging Probe (L1003QJ) − Rear Tank LH Front Gauging Probe (1403QJ) − LH Feeder Tank Gauging Probe (L1003QJ)
− CTR Feeder Tank Gauging Probe (M1003QJ) − Rear Tank Rear Gauging Probe (1503QJ) − CTR Feeder Tank Gauging Probe (M1003QJ)
− RH Feeder Tank Gauging Probe (R1003QJ) − LH Front Tank Gauging Probe (L1602QJ)
− CTR Center-Wing Tank Front Gauging Probe (1103QJ) − RH Front Tank Gauging Probe (R1602QJ) The information issued from the fuel density sensor of the LH feeder tank gauging probe (L1003QJ) is used by the FQMC
(208QJ) to correct the fuel quantities held in the LH and RH tank groups.
The wing fuel gauging probes are:
− LH/RH Wing Inboard Tank Rear Gauging Probe (L203QJ)/(R203QJ) The information issued from the fuel density sensor of the CTR feeder tank gauging probe (M1003QJ) is used by the
FQMC (208QJ) to correct the fuel quantities held in the center tank group.
− LH/RH Wing Inboard Tank Front Gauging Probe (L303QJ)/(R303QJ)
− LH/RH Wing Middle Tank Rear Inboard Gauging Probe (L403QJ)/(R403QJ)
The fuel density sensors are working under the same principle as the fuel gauging probes are. They are also made of two
− LH/RH Wing Middle Tank Front Inboard Gauging Probe (L503QJ)/(R503QJ)
concentric tubes that make a capacitor.
− LH/RH Wing Middle Tank Outboard Gauging Probe (L603QJ)/(R603QJ)
− LH/RH Wing Outboard Tank Outboard Gauging Probe (L703QJ)/(R703QJ)
However, their limited height and specific location in feeder tanks ensure that they are always fully submersed in fuel.
− LH/RH Wing Outboard Tank Inboard Gauging Probe (L803QJ)/(R803QJ) Consequently, the capacitance between the active sections of the inner probe cylinder (high impedance) and of the outer
probe cylinder (low impedance) is now proportional to the density of the fuel. This capacitance is read by the FQMC
(208QJ).

Fuel Level Control Unit (FLCU) (308QJ)
The FLCU (308QJ) receives the 1000 lbs fuel level data from the 1000 lbs fuel level sensors. It sends the information to
the EASy system for display of the white "FUEL: TK 1 LVL", "FUEL: TK 2 LVL" or "FUEL: TK 3 LVL" CAS message.
The 1000 lbs fuel level sensors are based on a resistance which changes according to the environment: fuel or air. They
send their data to the FLCU (308QJ).
The LH temperature probe (L105QJ) is located in the LH feeder tank. The CTR temperature probe (M105QJ) is located in
the CTR feeder tank.
The temperature probes are composed of a platinum resistance and a protective body. The temperature probes are
resistors whose value varies with the temperature. The fuel temperature measurement accuracy is better than ± 2°C

REFUELING – DEFUELING AND DRAINING NOTES:
Overview
Fueling and Defueling
The refueling system allows two ways of refueling:
− Pressure Refueling
− Gravity Refueling
The pressure refueling is performed through the pressure refueling coupling (201QF), the refueling manifold (303QF) and
six refueling valves (102QF), (202QF), (302QF), (402QF), (L402QF) and (R402QF).
The three tanks groups can be selected independently to perform the pressure refueling. The gravity refueling system is
ensured through the LH (L101QS) or RH (L101QS) gravity refueling plug. The LH / RH gravity refueling plug allows the
refueling of the LH / RH tank group without the LH / RH front tank. In this case, the refueling of the LH and RH front tanks,
the center and RH / LH tank groups is performed by transferring fuel from one tank group to the others.
The draining system evacuates the water accumulation in the tanks or to do a full defueling after a suction or gravity
defueling.
The draining of the tanks is performed by the sump drain valves, located at low point levels of the tanks. This system
works by gravity. A spirit level installed in the NLG bay permits to easily make sure that the aircraft pitch angle on ground
is adequate for draining. The defueling system enables:
− Defueling by suction
− Defueling by gravity
The suction defueling is performed through the defueling manifold and the fueling manifold up to the filler connector,
where the truck is connected.
All vent valves must be open to begin the operation. The defueling switch on the maintenance panel and the pushbuttons
on the overhead panel manage the opening of the BP manifold fuel transfer valves and of the defueling manifold, and to
control the selection of the tanks to be defueled, by energizing the corresponding booster pumps.
The gravity defueling is performed through the BP manifold fuel transfer valves and the defueling manifold, with the
booster pumps energized.
In any case, the defueling can be done from one, two or all the three tank groups at the same time.

High-Level Sensors
The aircraft has a total of eight high-level sensors. Five of them are independent:
− LH Wing High-Level Sensor (L104QJ)
− RH Wing High-Level Sensor (R104QJ)
− CTR High-Level Sensor (M104QJ)
− LH Front High-Level Sensor (L204QJ)
− RH Front High-Level Sensor (R204QJ)
The LH (L204QJ) and RH (R204QJ) front high-level sensors send their data to the FQMC (208QJ) which transmits it to
the front tank PCB (408QJ). The six others high-level sensors send their data directly to the FLCU (308QJ).

The FQMC has:
− 13 discrete inputs coming from the RCP: Fuel Level Control Unit (FLCU) (308QJ)
• Eight inputs corresponding to the refueling valves control:
▪ Four for the partial refueling and four for the full refueling: one for the LH tank group, one for the RH tank
group, and two for the center tank group (front and rear)
• Two inputs for the increasing / decreasing of the target quantity used for the partial refueling
• One input for the transmission of the RCP fault to send a RCP fault to the avionics
• One input for the fueling test
• One input for the power of the RCP to know if the RCP is powered
− One discrete and 17 numerical inputs coming from the FLCU:
• Power of the FLCU to know if the FLCU is powered (discrete)
− 12 inputs corresponding to the six high-level sensors monitored by the FLCU, one signal corresponds to the state
(failed or not failed), the other corresponds to the status (high-level detected or not)
• Four inputs corresponding to the refueling valves status (open or closed) monitored by the FLCU
• One input for the fueling test
− Five discrete outputs towards the FLCU:
• Four discretes to control four of the refueling valves
• One discrete corresponding to the weight on wheel condition
− Two discrete outputs towards the front tank PCB (408QJ) to control the two front tank refueling valves and the “FULL”
lights of the RCP
− Two numerical outputs towards the RCP:
• Preselected fuel quantity for the "TOTAL QTY SELECT" digital display (9507QJ)
• Total aircraft gauging quantity for the "TOTAL QTY" digital display (9502QJ)
− 19 numerical outputs towards the Avionics:
• Two outputs for the status and state of each of the eight high-level sensors

REFUELING – DEFUELING AND DRAINING (CONTINUED)
Components (Continued) RH Front Tank Refueling Valve (R402QF) and Check Valve (R404QF)
The refueling manifold (303QF) is mainly composed of one body which includes:
− Four downstream end fitting diameter 1 ¼’’ to four refueling lines (one for each wing tank, one for the CTR center
wing tank and one for the rear tank)
− One end fitting diameter 1 ¼’’ for connection to the defueling manifold and to the front tanks refueling line
− One upstream end fitting diameter 2 ½’ ‘ for connection to the pressure refueling coupling
One shut off valve diameter 2 ½” is also integrated inside the body. The shut off valve is a ball valve type. The ball valve is
operated by a single motor actuator equipped with a manual control lever. Thermal expansion of the fuel volume between
the pressure refueling coupling and the shut off valve is managed by means of an over pressure valve. The actuator can
be removed without removing the refueling manifold (303QF).
Refueling Valves
The aircraft has six refueling valves:
− CTR Front Refueling Valve (102QF)
− CTR Rear Refueling Valve (202QF)
− LH Refueling Valve (302QF)
− RH Refueling Valve (402QF)
− LH Front Tank Refueling Valve (L402QF)
− RH Front Tank Refueling Valve (R402QF)
LH Front Tank Refueling Valve (L402QF) and Check Valve (L404QF)
The refueling valves are connected to the refueling manifold. There is one valve for each wing tank group, two valves for
the center tank group (one valve for the CTR center tank and another one for the rear tank), and two valves for the front
tanks (one for the right area and one for the left area).
In normal conditions, the valve is in closed position. The valve is open by an electrical signal in refueling or transfer
condition and when a pressure is present upstream of the valve. The electrical signal is controlled by the pushbuttons
installed on the refueling control panel (108QJ):
− "LEFT - ON/OFF" Switch (L9501QJ)
− "RIGHT - ON/OFF" Switch (R9501QJ)
− "CENTER - ON/OFF" Switch (M9501QJ)
The check valves are connected after the refueling valves on the six refueling lines (one check valve per pipe) and they
ensure a non return fuel flow. The non return function is performed by a ball blocking the flow. In normal fuel flow, the
same ball is pushed to allow the delivery of fuel.

Components (Continued)
Pressure Refueling Coupling (201QF)
The pressure refueling coupling (201QF), fitted with the refueling cap (101QF), is used for pressure refueling. The
refueling cap (101QF) is locked by the refueling coupling lever (9500QS).
Before the refueling, the refueling coupling lever (9500QS) must be set down to open the refueling cap (101QF). In this
position the coupling lever controls the de-pressurization of the fuel tanks. Then, the pressure refueling coupling (201QF)
is connected to the fuel truck.
For the gravity refueling, the defueling manifold transfer valve (9500QV) is controlled by the "DEFUELING" switch
(115QV) and allows the fuel to go from the BP manifold 1 / 3 to the refueling valves.

Fuel Tank Drain Valves
The aircraft has nine drain valves: five located under the fuselage and two located under each wing.
The fuselage drain valves (three located under the CTR center-wing tank and two located under the rear tank) are:
− CTR Center-Wing Tank Front Drain Valve (502QV)
− CTR Center-Wing Tank Middle Drain Valve (602QV)
− CTR Center-Wing Tank Rear Drain Valve (702QV)
− Rear Tank Drain Valve (802QV)
− CTR Feeder Tank Drain Valve (1002QV)
The sump drain valve is made up of a body with a flanged and a piston valve with a spring. In normal conditions, the valve
is in closed position. The sealing between the fixation of the drain and the aircraft is done by an O-ring seal.
The piston valve opens by pushing and turning of 90° the cap. The body and the piston are in alloy aluminum with a
anodizing chromic as protection against corrosion effects.

refueling stopping through the high level sensors (for the full refueling) and the gauging probes through the FQMC (for the
partial refueling). If the refueling does not stop automatically, the vent valves ensure the overflow of the tanks.
The front tank PCB (408QJ) controls the two wing pressurization valves opening and the front tank refueling valves
opening. It also checks the open status of the two wing pressurization valves to enable the refueling.
In full pressure refueling, all the refueling valves are open in order to refuel the three tank groups together. The refueling
valves can be controlled group by group to allow a specific tank group refueling.
Downstream of each refueling valve, a check valve is installed to avoid a non controlled fuel transfer.
When a high level is detected, the front tanks sensors send the information to the FQMC and the other sensors to the
FLCU to control:
− Closing of the respective refueling valve to stop the refueling
− Lighting of the full lights of the RCP
The FQMC calculates the fuel quantity in the tanks and sends it to the RCP which displays it in the "TOTAL QTY" digital
display (9502QJ). For a partial refueling, the fuel quantity calculated by the FQMC is directly used to control the closing of
the refueling valves and stop the refueling.

REFUELING – DEFUELING AND DRAINING (CONTINUED)
Operation (Continued)
Gravity Refueling
The gravity refueling can be performed through the LH gravity refueling plug (L101QS) or RH gravity refueling plug
(R101QS) located on each wing tank.
In this case, the other tanks are refueled by transferring fuel from the LH / RH wing tank to the others tanks:
− "BOOST 1" pushbutton (L9800PM) / "BOOST 3" pushbutton (L9840PM) starts the booster pump 1 / 3 which transfers
fuel from the LH / RH wing tank to the BP 1 (9631QD) / 3 (9651QD) manifold transfer valve
− "DEFUELING" switch (115QV) opens the defueling manifold transfer valve (9500QV) and the BP manifold fuel
transfer valves (9631QD), (9641QD) and (9651QD) to transfer fuel from the booster pump to the refueling manifold
(303QF)
− Refueling manifold transfers fuel to the refueling valves
− Refueling valves are opened by the relevant switches of the RCP
− Fuel goes directly from the refueling valves to the relevant tank
The gravity refueling is manually stopped when the necessary fuel quantity, shown on the “FUEL” synoptic page, is
reached.
Defueling
Suction Defueling
The booster pumps (L106QD) / (L206QD) / (M106QD) / (M206QD) / (R106QD) / (R206QD) are controlled from the
overhead panel. They transfer the fuel from the tank group to the LH (405QD) and RH (505QD) crossfeed units and the
BP 2 manifold fuel transfer valve (9641QD). The crossfeed units transfer the fuel to the booster pump 1 (9631QD) and 3
(9651QD) manifold fuel transfer valves.
The defueling manifold transfer valve (9500QV) and the BP manifold fuel transfer valves are controlled by a
"DEFUELING" switch (115QV). The BP manifolds transfer the fuel to the defueling manifold transfer valve, then to the
refueling manifold (303QF).
The opening of the vent valves (for the de-pressurization of the tanks) and the refueling manifold is controlled by the fuel
servicing door microswitch (211QS) and the refueling coupling lever microswitch (111QS). The refueling manifold
transfers the fuel to the pressure refueling coupling (201QF) which is connected to the truck.
It is possible to defuel a specific tank group, only by starting the corresponding booster pumps. The aircraft has to be
plugged on ground to prevent the electrostatic effects on the tanks during the defueling operation.
Gravity Defueling
The fuel transfer and controls are the same as the suction defueling until the defueling manifold. For the gravity defueling,
the gravity defueling valve (9510QV) is manually controlled by a lever. The defueling valve transfers the fuel directly in a
drain container. As for the suction defueling, the tank groups are selected by starting the corresponding booster pumps
from the overhead panel, the aircraft must be plugged on ground and the tanks must be de-pressurized.
Draining
The water or fuel draining of the tanks is performed through nine sump drain valves, located at low point levels of the
tanks. These sump drain valves open by pressing in and turning of 90° the cap with help of a draining bottle equipped with
screwdriver tool. The sump drain valves are designed with an O-ring seal to avoid any trickles of fuel. If necessary, this
seal can be changed without emptying the tanks, except for the wing root sumps.

HYDRAULIC SYSTEM NOTES:
Overview
The aircraft is provided with a hydraulic power system, operating with MIL-PRF-5606 hydraulic fluid. The hydraulic power
system has the subsystems that follow:
The primary hydraulic power system has the functions that follow:
− Control and monitor the EDPs to provide hydraulic fluid at constant pressure to the hydraulic systems A, B and C
− Relieve excess fluid pressure, to protect the system in case of EDP failure leading to excessive fluid pressure
− De-pressurize the EDP to reduce torque for engine start, or in case of system overheat
− Make sure that pressurized hydraulic fluid is delivered in priority to the flight control components that are essential for
the flight
− Control and monitor the isolation of hydraulic fluid from nacelle fire zone, to avoid extreme system overheat in case of
engine fire
− Avoid hydraulic fluid with a too high temperature in the lines passing through the fuel tanks
− Remove solid contaminants from the hydraulic fluid by means of hydraulic filters, and monitor the clogging status of
the filters
− Store hydraulic fluid and deliver fluid to EDP inlets
− Allow to connect hydraulic systems to an hydraulic ground power unit, for servicing and maintenance operation
− Prevent air ingress after engine shutdown
The backup pump operates from 2900 psi (200 bar) at a zero flow condition to 2.9 gpm (11 lpm) at 1500 psi (103.4 bar).
Indicating System
The hydraulic indicating system monitors the quantity, pressure and temperature of the hydraulic fluid. It sends the
information to the Enhanced Avionics System (EASy) that shows the associated indication in the cockpit.

HYDRAULIC SYSTEM (CONTINUED)
Components Manual Bleed / Pressure-Relief Valve
Hydraulic System Reservoirs A bleed / pressure- relief valve (L9501GP), (M9501GP) and (R9501GP) is installed on hydraulic system A, B and C. The
bleed / pressure-relief valve provides manual bleed and pressure relief capabilities. The bleed functions of the valve is
The reservoirs (601GP), (602GP) and (603GP) provides the necessary hydraulic fluid volume demanded by the hydraulic

system to include pressurization of the pump inlet. Change in the fluid volume due to thermal expansion/contraction,
system leakage and differential area of the user actuators have been taken into account in sizing the volume of each
reservoir. The major components of the reservoir are: The force necessary to operate the valve is 53.4 N (12 lbf) maximum used on the lever end during normal operating
− Low-pressure storage chamber pressure. When you release the lever, it will automatically return to the closed position. The pressure-relief valve operates
as follows:
− Bootstrap cylinder
Full flow pressure drop of 34 Lpm (9 gpm) at 10 bar (145 psi),
− Maintenance free hydraulic A reservoir accumulator (3601GP), hydraulic B reservoir accumulator (3602GP) and
hydraulic C reservoir accumulator (3603GP) Pressure of 6 bar (90 psi) to return the valve back to the closed position.
− Hydraulic A pressure-maintaining valve (L9502GP), hydraulic B pressure-maintaining valve (M9502GP) and hydraulic
C pressure-maintaining valve (R9502GP)
− Hydraulic A bleed / pressure-relief valve (L9501GP), hydraulic B bleed/pressure-relief valve (M9501GP) and hydraulic
C bleed/pressure-relief valve (R9501GP)
− Quantity indicator
− Hydraulic A temperature transducer (L9522GP), hydraulic B temperature transducer (M9522GP), and hydraulic C
temperature transducer (R9522GP)
− Hydraulic A temperature switch (L9509GP), hydraulic B temperature switch (M9509GP) and hydraulic C temperature
switch (3803GP)
− Pressure, suction and return ports
The minimum fluid storage capacities for the hydraulic systems reservoirs are as follows:
− Reservoir A (601GP), 7.4 l (450 cu.in)
− Reservoir B (602GP), 9.4 l (575 cu.in)
− Reservoir C (603GP), 4.1 l (250 cu.in)
Operation
Low Pressure Storage Chamber
Pressure by the bootstrap piston on the low-pressure piston maintains chamber pressure. With the bootstrap pressure at
207 bar (3000 psi), the chamber pressure is 3.8 ±0.2 bar (55 ±3 psi) for each reservoir. This chamber pressure will be
maintained with flows up to 34 Lpm (9 gpm) and deliver flows up to 72 Lpm (19 gpm) through the reservoir, over the fluid
temperature range of -7 to 107 °C (20 to 225 °F).
The reservoir (601GP) and (602GP) have the same diameter storage chamber. The reservoir (603GP) has a smaller
storage chamber piston diameter. A drain is provided to route any hydraulic fluid leakage overboard.
Bootstrap Cylinder
The bootstrap cylinder contains a small-area piston exposed to system pressure, nominally 207 bar (3000 psi), which
provides the force to drive the low-pressure piston and pressurize the reservoir.

HYDRAULIC SYSTEM (CONTINUED)
Hydraulic System B Thermal Fuse (3802GP)
Components (Continued)
Hydraulic System A & B Temperature Switches
The hydraulic system A and B hydraulic reservoir have a temperature switch (L9509GP) and (M9509GP). The switch
activates the hydraulic pump A1 (R201GP) and hydraulic pump B2 (M202GP) depressurization solenoids through the
HSCB (3801GP), when the hydraulic fluid gets too hot.
The sensor is a single-pole, double-throw temperature-sensing switch. The temperature switch operates by the increase
and decrease of fluid temperature. The switch closes when the fluid temperature in the reservoir increases to
92 ± 5 °C (197 ± 9 °F). The temperature switch opens when the fluid temperature in the reservoirs decreases to a
minimum of 62 °C (144 °F).
Operation
This sensor is a single-pole, double-throw temperature-sensing switch that is actuated by increasing and decreasing of
the fluid temperature. The switch closes when the fluid temperature in the tee-fitting increases to 257 ± 9°F (125 ± 5°C).
The switch opens when the fluid temperature in the tee-fitting decreases to 204°F (95.5°C).
When the switch closes, the solenoid of the hydraulic engine 2 system C SOV (803GP) is grounded through a latched
relay, which causes the valve to close automatically.
The sensor is a resistor temperature Device (RTD) that generates resistance as a function of fluid temperature. The
temperature transducer transmits electrical signals proportional to the hydraulic system temperature. The transmitted
signal goes to the cockpit for monitoring of the hydraulic system A, B and C temperature.
Thermal Fuse
There is one eutectic thermal fuse in the hydraulic system A and B reservoirs (Hydraulic A Thermal Fuse (4001GP) and
Hydraulic B Thermal Fuse (3802GP)). The role of these thermal fuses is to prevent the temperature of the hydraulic fluid
and of the tubing passing through the fuel tanks from exceeding the ignition temperature of the fuel vapors during extreme
failure conditions. The fuses provide an independent and redundant protection against overheat. Upon failure of the
hydraulic system causing an overheat, the fuse material will melt and drain the hydraulic fluid overboard.
Operation
System A
If the fluid in the reservoir reaches 292° F (~143° C), the fuse releases the hydraulic fluid to an overboard drain. The
eutectic fuse is located in a tee fitting directly mounted in system A reservoir return port. Msg3-29-15-00-008

The FWSOVs (L801GP), (R801GP), (M802GP), (R802GP) and (803GP) are electrically-controlled, two position ball valve,
located in the suction lines of the hydraulic engine driven pumps (EDP) that follow:
− Hydraulic Pump A1 (R201GP)
− Hydraulic Pump A3 (L201GP) Hydraulic System C Firewall Shutoff (203GP)
− Hydraulic Pump B2 (M202GP)
− Hydraulic Pump B3 (R202GP)
− Hydraulic Pump C2 (203GP)
During normal operation, fluid from the applicable hydraulic A reservoir (601GP) hydraulic B reservoir (602GP) and
hydraulic C reservoir (603GP) is ported through the applicable FWSOV to the applicable EDP. When the FWSOV is
operated to the closed position, the suction line is isolated from the EDP which prevents hydraulic fluid from reaching the
engine, should an engine fire occur.
The FWSOV includes a visual position indicator and position indicator electrical switches to provide indication of the
FWSOV position to the cockpit.
A thermal relief valve is provided for protection of the downstream system when the FWSOV is closed.
During the FWSOV opening cycle, the contacts of the open-position-indication switch close (to ground) when the valve
ball reaches 86° open.
The closed-position-indication switch operates during the valve closing cycle and its contacts close when the valve ball is
within 4° of fully closed. The position indicator switches are a bifurcated type, that use gold-plated contacts, and are
environmentally sealed.
Operation
The motor operates through a planetary gearset to drive the valve ball through a 90° arc. The FWSOV will move from fully
open to fully closed, or in the opposite direction, within no more 1.5 seconds, with 28 V DC applied (1.0 Ohm of line
resistance) and fluid temperatures above -7 °C (20 °F). With application of 16 V DC and fluid temperatures down to -
40 °C (-40 °F) the valve will cycle in either direction in no more than 2.5 seconds.
When the FWSOV is fully open, it will flow 38 Lpm (10 gpm) with a pressure drop of 0.09 bar (1.3 psi) maximum at
37.8 °C (100 °F). The FWSOV includes a visual position indicator that moves to the “OPEN” or “CLOSED” position.

Hydraulic Service Panel Connections
The hydraulic service panel provides ground service fittings that make it easy to do maintenance when servicing from a
ground cart. The hydraulic system A has the quick disconnects (1601GP), (2001GP) and ground filling valve (2401GP).
The hydraulic system B has the quick disconnects (1602GP), (2002GP) and ground filling valve (2402GP). The hydraulic
system C has the quick disconnects (1603GP), (2003GP) and the ground filling valve (2403GP).
Operation
The quick disconnects are Parker's 44000 series GSE couplings. These quick disconnects offer efficient sealing during
connection and disconnection due to its elastomeric and thermoplastic seals. A knurled outer surface provides a positive-
grip and ensures that the actuation sleeve is always in the correct position during connection and disconnection of the
quick disconnects. A retaining ring prevents the actuation sleeve from sliding down the hose. Each coupling’s actuation
sleeve engages a ratchet-locking device to prevent accidental disconnection when coupled.
The exposed end of the quick disconnects are supplied with a dust caps to protect the threads and stop the collection of
dust and moisture on the coupling. When the dust caps not installed, they are attached to the aircraft structure by a
flexible stainless steel cable next to the quick disconnect coupling.
The ground filling valves is a pneumatic high pressure charging valve per MIL-PRF-6164F. The dust cap also prevents
dust collection and moisture on the valve end.

cylinder barrel that contains nine pistons.
Each EDP has a pressure compensator, which change the volume of fluid delivered to maintain constant system
pressure. The EDP mounts to the gearbox on a flange. The EDP has discharge, suction and case drain hydraulic ports.
The case drain port is located on the top of the EDP for increase case drain fluid flow to decrease the temperature of the
EDP components. This location makes sure that the air is bled from a new EDP after installation. Each EDP includes an
integral attenuator ball on the discharge to provide pressure ripple and noise reduction. The pump timing and
displacement controls provide for low-pressure ripple and smooth response to rapid changes in flow demand.
The hydraulic system A and B EDPs have a maximum displacement of 0.31 cubic inches per revolution
(CIPR) or 5.08 cc/rev with a counter clockwise rotation when seen from the pump input shaft. The 7500 rpm speed
minimizes heat rejection while maximizing reliability. A pressure hose, suction hose and case drain tube assembly
connect to the EDP. The hose and tube assemblies accommodate installation tolerances and also act as pulsation and
vibration dampers. The System A & B EDPs incorporate a 2-position, 3-way solenoid valve to reduce the discharge
pressure and input torque required during engine starts and windmill relights, or in case of system overheat.
Operation
As the barrel rotates, the pistons reciprocate within their bores, taking in and discharging fluid through a stationary valving
surface on the port cap. The displaced volume from the pump is controlled by the inclined angle of the hanger. The
hanger angle is controlled by discharge pressure through a compensator valve and stroking piston such that, above the
set pressure, the hanger angle decreases which reduces the displaced volume thus maintaining constant discharge
pressure.
The cylinder barrel is supported by a roller bearing that allows the rotating barrel alignment freedom and is so placed to
react to loads that are produced by the pumping forces. Radial loads are transferred through the bearing to the pump
housing. Axial forces on the piston/shoe subassembly are balanced by porting pressurized fluid through the piston neck to
a hydrostatic balance area under the piston shoe. Fluid enters and leaves the barrel through kidney shaped slots that
match annular slots in the port cap. The barrel slots are designed such that a hydrostatic balance is developed at the
barrel to port plate interface. The cylinder barrel is allowed to align itself with the port cap through the arrangement of the
drive shaft and cylinder barrel bearings.
Each of the System A & B EDPs incorporates an integral attenuator ball on the discharge to provide pressure ripple and
noise reduction.

The Hydraulic System Control Board (HSCB) (3801GP) controls the A1, B2 and B3 EDP depressurization solenoids. The
HSCB (3801GP) uses control logic and depressurizes the applicable EDPs to reduce torque for engine start, or to avoid
high fluid temperatures. The HSCB is mounted to a bracket to support a 50 pin connector. The bracket has two pins that
do not match. This prevents the HSCB from being installed in the wrong slot.
The Hydraulic System Control Board (HSCB) (3801GP) controls the hydraulic backup pump (1002GP). The backup pump
is commanded to start by the HSCB:
− If the hydraulics "BACKUP PUMP" pushbutton (R9540PM) is set to “ON”
OR
− If the hydraulics "BACKUP PUMP" pushbutton (R9540PM) is set to normal mode (automatic control), and there is a
low pressure detected by the hydraulic A and B EDP pressure switches.
Operation
The valve (1401GP) and (1402GP) is a simple in-line device that contains a pressure relief valve and check valve in
parallel. The valve (1401GP) and (1402GP) controls the flow of fluid as a function of inlet pressure. The valve (1401GP)
and (1402GP) closes off flow when the downstream pressure falls to a reseat pressure of 103 bar (1500 psi) and opens at
a full flow pressure not to exceed 124 bar (1800 psi). At a rated flow 38 Lpm (10 gpm), the pressure decrease across the
valve is 7 bar (100 psi) maximum with 124 bar (1800 psi) pressure or greater at the inlet port and 38° C (100° F) fluid

combinations of DC power and hydraulic system failure conditions to ensure maximum availability of flight critical
functions. The hydraulic backup pump pressure switch (9520GP) is rated at:

The pump attaches to the aircraft structure by a mount plate and four bolts. It contains a discharge and suction port. A − 76 bar (1100 psi) min. for decreasing pressure values
seal drain fitting is connected to a drain hose. Electrical power for the pump transmits through stud terminals. Each
terminal stud has a separate connector for the thermal switch and the brush life indicator. For ground maintenance
activities only, the pump can be manually selected to power the hydraulic system A.
Operation
The pump (1002GP) is a variable displacement, axial piston type unit. Inside the pump is a cylinder barrel that contains
nine pistons. An electric motor drives the pistons. The pistons have limited movement with the piston shoes against an
angled plate (hanger). This movement causes the pistons to reciprocate in the barrel bores as the barrel turn which
provide the pumping action. The shoes are hydrostatically balanced to provide lubrication at the shoe-have interface. The Backup Pump Pressure Switch (9520GP)
hanger pivots on it own axis which changes the angle relative to the pistons and provides variable displacement. The
barrel mounts in a barrel bearing and loads against the port plate by balanced hydraulic force and the barrel spring.
As it barrel rotates, the barrel bores communicate with the inlet and discharge ports in the port plate. This effect fills the
bores during the inlet stroke and delivers fluid during the discharge stroke. The pump discharge pressure operates with
the compensator valve spool and directs a small stroking piston. As the pressure increases, the spool moves against the
spring force of the valve. Also the small stroking piston moves against the pump-hanger and the spring force of the rate
piston. If the force of the small stroking piston is higher than the adjusted spring force of the rate piston, the pump hanger
will travel to a smaller angle. This device automatically maintains a minimum pressure-flow output along a relatively
constant horsepower line from 11 Lpm (3 gpm) at 103 bar (1500 psi) to 4 Lpm (1 gpm) at 197 bar (2850 psi) at a rated
voltage of 27 volts.
When the pressure reaches a value decided by setting of the compensator spring, the spool opens a port and the valve
transfer fluid to the large stroking piston which strokes the pump-hanger to an angle of zero. When system pressure falls
below the compensating valve setting, the fluid then goes from the stroking piston to the pump case. Now, the hanger
angle increases.
The pump has a maximum displacement of 1.47 cm³ (0.09 cu.in) per revolution CIPR or 1.5 cc/rev with a CCW rotation
when you look into the direction of the pump input shaft. The 7500 rpm speed selected minimizes heat rejection while
maximizing reliability.
Operation
The selector valve switches both the suction and discharge lines of the pump from the hydraulic system A to the hydraulic
system B. The selector valve design prevents any possibility of fluid travel from one system to the other. The selector
valve utilizes rip-stop construction. In an event of structural failure, it will not result in the loss of both hydraulic system A
and B fluid pressure. The housings for each system do not interface with each other.
A pin is used to latch in the selector valve in both the “GROUND” (system hydraulic A powered) and the “FLIGHT”
(hydraulic system B powered) position. An electrical switch is provided to status spool position to prevent dispatch with the
selector valve (1202GP) set to the “GROUND” position.

HYDRAULIC SYSTEM (CONTINUED) NOTES:
Operation
Hydraulic Power Generation and Control System
Normal Operation – Hydraulic Fluid Pressurization and Distribution
When an Engine Driven Pump (EDP) is operating, it pumps hydraulic fluid stored in the corresponding hydraulic reservoir,
through the suction line. The bootstrap type hydraulic reservoir provides sufficient static pressure to deliver fluid to the
pump at the required flow rate, above the pump critical inlet pressure. The hydraulic fluid crosses the hydraulic firewall
shut-off valve before entering the pump, where it is pressurized to a constant pressure of 3000 psi (207 bar).
The pressurized fluid is then routed to the aircraft hydraulic components, through the hydraulic pressure lines. To remove
any solid contaminant that may come out from the pump, a pressure filter element is installed on the pressure line. The
fluid provides hydraulic power to the aircraft hydraulic components, as requested. The hydraulic reservoirs have sufficient
fluid volume, and the EDPs a sufficient flow rate, to sustain the high demand components such as the landing gears.
However, the system A and B pressure lines include a priority valve to make sure that the pressurized hydraulic fluid is
delivered in priority to the flight control components that are essential for the flight.
After having crossed and powered the hydraulic components, the fluid is routed back to the hydraulic reservoir through the
return lines. To remove any solid contaminant that may come out from the hydraulic components, a return filter element is
installed on the return line.
A case drain line returns the hydraulic fluid from the EDP case drain to the hydraulic reservoir. To remove any solid
contaminant that may come out from the EDP case drain, a return filter element is also installed on the case drain line.
To ease access and maintenance of the hydraulic system components, each hydraulic system A, B and C includes an
hydraulic manifold installed in the mechanics servicing compartment, which contains:
− The pressure, return and case drain filter assemblies, fitted with automatic shutoff valves to prevent loss of fluid and
air ingestion during filter element replacement
− The electrical differential pressure indicator (DPI) associated to each filter assembly
− The system pressure relief valve
− The system pressure transducer
− The pressure switch associated to each pump powering the system

HYDRAULIC SYSTEM (CONTINUED)
Operation (Continued) The backup pump is commanded to start by the HSCB:
Hydraulic Isolation System − If the hydraulics "BACKUP PUMP" pushbutton (R9540PM) is set to “ON”, or
Priority Management − If the hydraulics "BACKUP PUMP" pushbutton (R9540PM) is set to normal mode (automatic control), and there is a
low pressure detected by the hydraulic A and B EDP pressure switches.
The hydraulic A priority valve (1401GP) and the hydraulic B priority valve (1402GP) are installed in the hydraulic systems
A and B ahead of the utility users of the hydraulic components. When needed, the priority valves give pressure delivery
priority to the flight control components that are necessary for flight.
The hydraulic engine 1 system A SOV (L801GP) is operated to the closed position either by:
− Hydraulics "SHUT OFF A1" Pushbutton (R9520PM)
OR
− "FIRE 1" Switch / Light (950WZ).
The hydraulic engine 3 system A SOV (R801GP) is operated to the closed position either by:
− Hydraulics "SHUT OFF A3" Pushbutton (R9530PM)
OR
− "FIRE 3" Switch / Light (960WZ).
The hydraulic engine 2 system B SOV (M802GP) is operated to the closed position either by:
− Hydraulics "SHUT OFF B2" Pushbutton (R9550PM)
OR
− "FIRE 2" Switch / Light (955WZ).
The hydraulic engine 3 system B SOV (R802GP) is operated to the closed position either by:
− Hydraulics "SHUT OFF B3" Pushbutton (R9560PM)
OR
− "FIRE 3" Switch / Light (960WZ).

EDP De-pressurization
De-pressurization at Engine Start
The system A and B EDPs have a solenoid valve which is used to reduce the discharge pressure and input torque
required during engine starts and windmill relights. The hydraulic system C EDP does not have such a de-pressurization
solenoid valve, due to its smaller displacement and the lower load induced on the engine gearbox.
The FADEC’s energize the corresponding EDP depressurization solenoids to minimize engine drag torque for ground
starts and for in air engine restarts. The pump will only produce full pressure when its respective engine speed reaches
40% N2.
If all three engines are non-operational during flight, but are windmilling at a speed greater than 15% N2, the EDPs A1,
A3, B3, and B2 are not de-pressurized so that they can provide limited hydraulic power to the hydraulic systems from the
windmilling engines. The EDPs will be de-pressurized when windmilling engine speed reduces below 15% N2 to minimize
the engine load during a relight attempt.

MAINTENANCE CONSIDERATIONS NOTES:
CAUTION: When you clean a grease or oil leakage, use only approved cleaning materials. Some cleaning
material can cause damage to hydraulic parts and composite materials.
20) Make sure that all quick disconnects and hoses are cleaned with isopropyl alcohol before use.
CAUTION: If the aircraft is not in a slats retracted configuration, it is mandatory to do the pressurization of the
hydraulic system a first and then do the pressurization of the hydraulic system b, even if only
hydraulic system is to be used for the procedure.
21) If the slats are not retracted, you must pressurize hydraulic system A before you pressurize hydraulic system B.
22) Do not operate the hydraulic backup pump (1002GP) when a hydraulic ground power unit (TO-29-010) is connected
to the system.
23) If the reservoir level is less than 20%, do not operate the hydraulic system pump(s).
WARNING: DO NOT PRESSURIZE THE HYDRAULIC SYSTEMS WITH A GROUND POWER-UNIT WITHOUT
THE RETURN LINE CONNECTED. IF THE RETURN LINE MUST Go INTO A CONTAINER, MAKE
SURE THE RETURN LINE IS OPEN BEFORE YOU APPLY PRESSURE. YOU CAN CAUSE
DAMAGE TO THE HYDRAULIC SEALS The System Or Cause Injury To Personal.
24) If the aircraft return pipe is not connected, do not pressurize the hydraulic system with a ground hydraulic source.
25) Do not operate the hydraulic Ground Power Unit (GPU) in “CLOSED LOOP” mode. This can cause damage to the
aircraft mounted hydraulic reservoirs.
26) Obey the hydraulic precautions that follow:
a) Do not use an external power pump to service a hydraulic system reservoir.
b) Only use a hand carry hydraulic fluid unit (TO-29-140) or on wheel hydraulic fluid unit (TO-29-150) to prevent
damage to the aircraft (Refer to TASK 29-00-00-610-801).
27) If you have an external hydraulic fluid leak (Refer to TASK 29-00-00-790-801).

Overview Ice Detector System
The aircraft is equipped with two anti-icing systems: The ice detector system includes two ice detectors (L101DD) / (R101DD), symmetrically mounted on the forward
fuselage. It detects all types of natural in-flight icing conditions and provides an ice signal to the crew through the avionics
− Pneumatic system that uses hot air bled from the engines, to protect when ice accretion on the ice detector probe reaches a predetermined threshold.

− Smart Probe
− Cockpit Windshields
− Water Lines
Engine No 1 and No 3 systems provide anti-icing for cold air unit. As an option, it can also heat the brake units. The
aircraft also includes an ice detection system and a rain protection system that follow:
− Ice detection system provides the crew with a real-time indication concerning the presence of icing conditions
− Rain protection system allows sufficient visibility front windshields in rainy condition
The ice and rain protection system includes the sub-systems that follow:
The MFP contains the pneumatic ports necessary to supply total, static and angle attack pressures to the ADC pressure
sensors. The MFP gives the local pressure by the ADC sensors to calculate true pitot pressure, correct static pressure
and aircraft AOA.
Water Lines
The water system installed on the aircraft features electrically anti-iced components, in particular the water drain pipes
located in non-pressurized area and the drain masts located under the fuselage. They are equipped with a heating
element wrapped over the pipe length under the lagging.

ICE DETECTION SYSTEM
Overview
The ice detection system:
− Supplies the ice detection
− Supplies the health status of the ice detectors
− Supplies the Initiated Built-in Test (IBIT) function for the ice detectors
It sends the data to the EASy avionics system for the display of the related indication in the cockpit. The ice detection
system includes two ice detectors.
NOTE: After an Ice Detector failure, the system become “Advisory” which means the crew is to use Visual Cues
(visible moisture) and temperature.
Components
Ice Detector
The ice detector consists of a vibrating sensing element (probe) incorporated with a supporting strut that is exposed to the
airstream. The primary purpose of the strut is to extend the probe far enough into the airstream to allow droplets to
impinge on the sensing probe. As ice accumulates on the sensing element, ice accretion is detected by a change in the
sensing element’s resonant frequency.
The electronics primarily consist of a microcontroller with embedded software, signal conditioning and power supply
hardware. The microcontroller calculates the sensor frequency, controls heater functions, regulates output signals, and
performs the various built-in-test (BIT) functions. The internal software controls two discrete output signals that interface
with the aircraft avionics in a manner suitable for display of any icing conditions encountered or failures for manual
activation by the crew of aircraft ice protection systems. The ice detector also incorporates built-in test (BIT) with remote
press-to-test (PTT) capability.

operation. Subsequent PTT commands are prevented until the ice detector power is operated OFF and then back ON.
The IBIT function is available on the ground or in flight. The only time that the ice detectors prevent the PTT command is
at the start period after power on (approximately 7 seconds). The ice detectors also prevent the PTT command when one
or the other ICE Signal is ON.

WING ANTI-ICING
NOTES:
Overview
The wing anti-icing system uses a temperature control valve, temperature sensors, pressure sensors and pressure
switches to monitor and control the hot bleed air supplied to the left and right wings. The primary components of the wing
anti-icing system are:
− Wing Anti-Ice Temperature Control Valve (R201DL)
− LH Wing Anti-Ice Pressure Sensor (L401DL)
− RH Wing Anti-Ice Pressure Sensor (R401DL)
− LH Wing Anti-Ice Temperature Sensor (L601DL)
− RH Wing Anti-Ice Temperature Sensor (R601DL)
− LH Wing Anti-Icing Pressure Switch (L801DL)
− RH Wing Anti-Icing Pressure Switch (R801DL)
The temperature and pressure in the wing anti-icing system is controlled by modulation of the wing anti-ice temperature
control valve (R201DL).
The AMSAC (1003HN) controls the wing anti-ice temperature control valve (R201DL) to supply bleed air for left wing and
right wing anti-icing.
The pressure in the wing anti-icing system is monitored by the AMSAC (1003HN) through two pressure sensors. The
pressure sensors used are the LH wing anti-ice pressure sensor (L401DL) and the RH wing anti-ice pressure sensor
(R401DL).
Hot air leaks in the wing anti-icing system is sensed by two pressure switches, the LH wing anti-icing pressure switch
(L801DL) and the RH wing anti-icing pressure switch (R801DL).
The LH wing anti-ice temperature sensor (L601DL) is monitored by MAU 1 and the RH wing anti-ice temperature sensor
(R601DL) is monitored by MAU 2.
In emergency operation, the Air Management System Emergency Controller (AMSEC) (801HN) closes the wing anti-ice
temperature control valve (R201DL).

WING ANTI-ICING (CONTINUED)
Components A failure of one of the pressure switches will cause the fault message "A/I: WINGS PRESS SENS FAIL" to show on the
MAU. The fault message also occurs when a pressure is sensed with the wing anti-ice temperature control valve
Wing Anti-Ice Temperature Control Valve (R201DL)
(R201DL) in the closed position.
The wing anti-ice temperature control valve (R201DL) is a modulating and shut-off valve. The function of the valve is to
supply a controlled quantity of bleed air to the wing anti-icing system. The valve is installed in the un-pressurized belly
fairing below the baggage compartment floor. The valve includes a valve body, two electrical motors and a gear train. Temperature Sensors (L601DL) and (R601DL)
The sensors are dual bead types. Each sensor is a Resistance Temperature Detector (RTD) that uses two platinum
sensing elements. Each sensor includes a stainless steel body that is connected to a probe by a cable. The sensing

spur gears, worm-and-wheel gears and a clutch but they use the same planetary gears. The gear trains cannot be turned
in the incorrect direction. Four limit switches are installed in the valve. The limit switches are operated by cams. Two limit
switches operate when the valve is open and two limit switches operate when the valve is closed. One sensor is installed on the left hand wing, on the slat near the trailing edge. The other sensor is installed on the right
hand wing, on the slat near the trailing edge. One bead of each sensor is used by the AMSAC (1003HN) for system
control and monitoring. One bead from the LH wing anti-ice temperature sensor (L601DL) is used by MAU 1 and one

motor turns its gear train which then turns the butterfly plate. When the butterfly plate is at the end of its travel, a limit
switch operates and opens the electrical circuit. When the electrical power stops, the gear train holds the butterfly plate in
the set position. Operation
The probe part of the sensors is open to the external atmosphere. When the temperature of the sensing elements
increases or decreases, their resistance changes linearly.
The two electrical motors in the wing anti-ice temperature control valve (R201DL) are controlled by AMSAC module 1
(303HN) and AMSAC module 2 (403HN). The valve includes a manual override lever that, when pushed, retracts the
clutch ring from the clutch housing. This lets the butterfly plate move in each direction independently from the gear train Wing Anti-Ice Pressure Switch (R801DL)
and the motors.
A three-pin electrical connector is installed at one end of the body. At the opposite end is a pneumatic connector. One
pressure sensor is installed in each of the left and right hand supply ducts, downstream of the wing anti-ice temperature
control valve (R201DL).
Operation
The pressure in the wing anti-ice duct is applied to the pressure sensor and causes the diaphragm to move. The
movement of the diaphragm is measured by the strain gauges. The strain gauges change the measurement into a voltage
signal that is in proportion to the inlet pressure. The voltage signal changes in relation to the pressure that is applied to the
diaphragm. The output signal is also temperature compensated for increased precision.
Operation
An increase in pressure to 600.0 ± 50.0 mbar (8.7 ± 0.7 psi) will close the pressure switch and give an output signal. A
decrease in pressure to 450.0 ± 50.0 mbar (6.5 ± 0.7 psi) will open the pressure switch and remove the signal.

Double Skin Diffuser Box
The fixed leading edge root of each wing is uncovered when the inboard slat (L9500CM) / (R9500CM) is extended. To
prevent the icing of the fixed leading edge root, the root must be supplied with hot air. The double skin box supplies the
hot air to the double skin of the fixed leading edge root through several holes. The double skin box is a structural part of
the fixed leading edge root.
Telescopic Ducts
The hot air, coming from the insulated pipe, flows through the slat telescopic ducts (102DL) / (402DL), (202DL) / (502DL)
and (302DL) / (602DL). The telescopic ducts are designed to follow the movement of the slats by retraction and extension.
Each telescopic duct supplies each independent slat through piccolo ducts. The piccolo ducts are structural parts of the
slats and allow the slats to be supplied with hot air, whatever the position of the slats.

ENGINE AIR INTAKE ANTI-ICING
Overview Pressure Transducer
Engine inlet anti-icing systems are provided on the side and center engines on the aircraft. The engine inlet anti-ice
system prevents ice formation on the engine inlet lip allowing safe flight in icing conditions. Each engine is equipped with
a Thermal Anti-Ice (TAI) system. The engine TAI system uses hot air taken at its interface with the engine's high-pressure
bleed system.
The engine cowl anti-ice control and indication system contains the components that follow:
− The side engine inlet thermal anti-icing (TAI) venturi
− Three pressure regulating and shutoff valves (anti-icing valves)
− Three anti-icing pressure transducers
− Ducting
Components
Side Engine Inlet TAI Venturi
The function of the venturi is to limit the anti-icing system flow in the event of a downstream burst of either the anti-icing
supply or piccolo duct. The venturi will be sized to have an effective discharge area 10% greater than that of the piccolo
hole discharge effective area. In this manner, it will only control the flow following a downstream burst anti-icing duct and
limit the flow rate in case of a duct burst. Pressure Regulating Shutoff Valve (PRSOV)

ENGINE AIR INTAKE ANTI-ICING (CONTINUED)

Ducting
Supply Duct
The anti-icing supply duct is made to transmit the HP bleed air from the engine bleed air port to the piccolo pipe.
Upstream of the PRSOV, the ducting will get the bleed pressure and temperature if the anti-icing system is selected ON or
OFF. When the anti-icing system is selected OFF the ducting downstream of the PRSOV will be supplied low pressure air
approximately equal to ambient. When the anti-icing system is selected ON and the PRSOV is operating normally, the
ducting downstream of the PRSOV will be supplied the valve regulation pressure of 16.9 ± 0.35 bar (100 ± 5 psig).
Piccolo Tube
The piccolo pipe is a circular duct that interfaces with the anti-icing supply pipe. It is located within the forward area of the
Side Engine Exhaust Duct and Panel
inlet and has multiple drilled holes that direct the anti-icing air to impinge on the inner surface of the lipskin. In this way the
piccolo pipe acts as a hot air distribution pipe around the lipskin circumference. Three rows of holes are positioned to
ensure that the jets impinge at particular positions on the lipskin surface and provide high amounts of heat transfer.
The Side Engine TAI exhaust panel mixes the anti-icing exhaust air with the free stream air and causes minimum
blockage to the anti-icing exhaust flow that would increase internal pressures. A correct mix is necessary to prevent any
reattachment of the exhaust air with the downstream nacelle outer surface that can result in heat damage.

S-DUCT ANTI-ICING
Overview S-Duct Anti-Ice Dual Bead Skin Temperature Sensors (M601DL/M801DL)
The S-Duct anti-icing system uses a valve, temperature sensors and pressure sensors to monitor and control the hot The sensors are dual element platinum resistor types. The sensors are attached to the outer surface of the S-Duct:
bleed air supplied to the S-Duct. The primary components of the S-Duct anti-icing system are: − S-Duct anti-ice temperature sensor 1 (M601DL) is located at the end of S-Duct section 2 at an angle of 48 degrees to
− S-Duct Anti-Ice Temperature Control Valve (M1401DL) the plenum line,
− S-Duct Anti-Ice Temperature Sensor 1 (M601DL) − S-Duct anti-ice temperature sensor 2 (M801DL) is located at section 3 of the S-Duct, upstream of frame 41, at an
angle of 18 degrees to the plenum line.
− S-Duct Anti-Ice Temperature Sensor 2 (M801DL)
− S-Duct Anti-Ice Pressure Sensor 1 (M401DL
In normal operation, the sensors are used for control and monitoring:
− S-Duct Anti-Ice Pressure Sensor 2 (M501DL)
− S-Duct anti-ice temperature sensor 1 (M601DL) transmits temperature signals used to control the S-Duct anti-ice
temperature control valve (M1401DL) and for low temperature monitoring,
The AMSAC (1003HN) and the AMSEC controller (801HN) control and monitor the S-Duct anti-ice system:
− S-Duct anti-ice temperature sensor 2 (M801DL) transmits signals to control the S-Duct anti-ice temperature control
− The S-Duct skin temperature is controlled by the AMSAC module 1 (303HN) in NORM operating mode and AMSAC valve (M1401DL) if S-Duct anti-ice temperature sensor 1 (M601DL) fails, and for high temperature monitoring.

− In emergency ECS operation, the S-Duct anti-ice temperature control valve (M1401DL) is closed by the AMSEC
controller (801HN)
− S-Duct over-temperature monitoring is done by the AMSAC (1003HN) using one element of S-Duct anti-ice

Components
S-Duct Anti-Icing Temperature Control Valve (M1401DL)
The S-Duct anti-ice temperature control valve (M1401DL) is installed in the unpressurized equipment bay aft of frame 41.
The function of the valve is to supply bleed air for S-Duct anti-icing, based on signals from the S-Duct temperature and
pressure sensors. The valve is a shut-off valve that is electrically actuated. The valve includes a valve body, electrical
actuator, potentiometers and limit switches for position indication. The valve also includes a manual override.
In normal ECS mode, the valve is monitored and controlled by the AMSAC (1003HN). In emergency ECS mode, the
AMSEC controller (801HN) closes the valve. If there is no electrical power, the valve stays in its last set condition.
The crew can use the anti-ice "ENG 2" pushbutton (R9750PM) on the overhead panel (5000PM) to control or isolate the
valve.
Operation
The valve controls the airflow to regulate the skin temperature of the S-Duct measured by the sensors attached to the S-
Duct. The valve also limits the air pressure measured by the sensors installed downstream of the valve in the anti-ice
supply duct. The valve controls the S-Duct skin temperature to 44°C if the total air temperature (TAT) is more than -20°C,
or 56°C if the TAT is less than or equal to -20°C, using feedback from S-Duct anti-ice temperature sensor 1 (M601DL). If
sensor 1 is failed, the valve controls the S-Duct skin temperature to 57°C if the TAT is more than -20°C, or 69°C if the TAT
is less than or equal to -20°C, using feedback from S-Duct anti-ice temperature sensor 2 (M801DL).
Only one motor is energized at a time. The motor A is controlled by the AMSAC AMM1 and the motor B is controlled by
the AMSAC AMM2. When one motor is de-energized, it permits rotation of the motor armature of the energized motor to
be transferred through the gear train to the butterfly. When the butterfly reaches the end of its travel, a limit switch stops
the rotation of the butterfly by opening the circuit that supplies power to the motor. Upon interruption of the electrical
power, the gear train will hold the butterfly in the last selected position. Pushing the manual override lever in either
direction retracts a clutch ring from the clutch housing, allowing rotation of the butterfly independent of the gearbox and
motor.

The AMSAC (1003HN) and the AMSEC controller (801HN) control and monitor the S-Duct anti-ice system: If the sensor 2 is registered in failure, the overheat monitoring is done using the maximum temperature measurement

NOTES:
temperature sensor 1 (M601DL) and S-Duct anti-ice temperature sensor 2 (M801DL),
− S-Duct anti-ice over-pressure monitoring is done by S-Duct anti-ice pressure sensor 1 (M401DL) and the S-Duct anti-
ice pressure sensor 2 (M501DL).
The sensor is also considered in failure if one of both sensitive parts gives a temperature out of range. If the temperature
measured by the sensor 1 sensitive part linked to the AMSAC is registered in failure, the S-Duct temperature control is
done by the sensor 2 sensitive part linked to the AMSAC. In this case, the skin temperature measured by the sensor 2 is
regulated at 57°C ±2.5°C. On ground only, the “A/I: S-DUCT TEMP SENS FAIL” CAS message warns the pilot when a
skin temperature sensor is registered in failure.
Temperature Monitoring
For the skin temperature monitoring, skin temperatures of the S-Duct are provided by two dual bead sensors:
− The skin temperature sensor 1 is used for the low power monitoring
− The skin temperature sensor 2 is used for the overheat monitoring
If the CAS message remains after this pilot action during more than 5s consecutively below the altitude of 22000ft and
during more than 1 minute consecutively above the altitude of 22000ft, the pilot increases the engine settings. If the
CAS message still remains after this action during more than 5s consecutively below the altitude of 22000ft and during
more than 1 minute consecutively above the altitude of 22000ft, the pilot turns off the S-Duct A/I and avoids or leaves the
icing condition.
Overheat Monitoring
If the sensor 2 measures a temperature greater than 72°C ± 2.5°C during more than 2s consecutively and the S-Duct A/I
TCV is NOT CLOSED, the CAS message "A/I: S-DUCT HI TEMP" is displayed, then the pilot turns off the S-Duct A/I and
avoids or leaves the icing condition. If the CAS message remains after this action, the pilot closes the LH and RH
crossbleed valves and the central MP PRSOV.

SMART PROBE ANTI-ICING
Overview
The air data smart probe anti-icing system:
− Controls the Multi-Function Probe (MFP) heat
− Monitors the MFP heat
− Controls the Total Air Temperature (TAT) sensor heat
− Monitors the TAT sensor heat
It sends the data to the EASy avionics system for display of the related indication in the cockpit. It also sends the data to
the Primary Flight Control System for Air Data System monitoring.
Components
Overhead Panel
Each smart probe receives a discrete input from the overhead panel (5000PM) to activate or deactivate the MFP and the
TAT sensor heater. When the "PROBE 1+2" pushbutton (R9810PM) is in the 'ON' state, the LH upper air data smart
probe (501FE) and the RH upper air data smart probe (401FE) control the LH upper multi-function probe (L701FE), RH
upper multi-function probe (R701FE), LH TAT sensor (L101FE) and RH TAT sensor (R101FE) heaters.
When the "PROBE 3" pushbutton (R9820PM) is in the 'ON' state, the LH lower air data smart probe (301FE) controls the
LH lower multi-function probe (L601FE) heaters. When the "PROBE 4" pushbutton (R9830PM) is in the 'ON' state, the RH
lower air data smart probe (201FE) controls the RH lower multi-function probe (R601FE) heaters.
The automatic logic in the avionics and the manual operation by the pilot control the overhead panel probe heater
switches. The automatic logic is called “Virtual Pilot”. It is active when the aircraft is Weight-On-Wheels with the Park
Brake "on". The Virtual pilot:
− Switches the value of the overhead panel heater discrete to the 'on' state when the transition from "one engine
running" to "two engines running" is sensed
− Switches the value of the overhead panel heater discrete to the 'off' state when the transition from "two engines
running" to "one engine running" is sensed
The Virtual Pilot switches the overhead panel discretes to ON at aircraft power up and OFF at power down. The pilot can
push the appropriate overhead panel probe heater switch at any time to override the automatic logic.

Power-Up Built-in Tests
The duty cycle of the MFP heater power is changed to control the MFP temperature. For fail-safe design, the MFP heater During PBIT, the smart probe:
power duty cycle is 100%, or full-on, when the airspeed is more than 60 knots. On ground, when the airspeed is less than
60 knots, the smart probe regulates the MFP heater temperature by controlling the duty cycle. − Makes sure there is MFP and TAT sensor voltage input
− Cycles MFP and TAT sensor heater on/off to make sure of control circuit operation
Monitor of the MFP Heater − Makes sure there is MFP and TAT sensor heater element continuity
The MFP heater element current and voltage measurement gives the heater condition and annunciates any heater
element failures. At the end of the MFP and TAT sensor heater PBIT, the smart probe starts PBIT on any transition of the heater enable
discrete. The transition of the heater enable discrete goes from inactive to active, as soon as the MFP and TAT sensor
heater voltage is available.
In normal operation, the primary channel controls the heat, while the other smart probe channel monitors the heater power
lines. If the primary channel sends an error message to the other channel, or, the monitor channel detects the MFP is not
receiving power, it will take over the operation. Both channels monitor the current and voltage of the MFP power lines in Continuous Built-in Tests
multiple places to make sure that correct detection of failure conditions occurs. If a failure in the primary channel circuitry During CBIT, the smart probe:
occurs, the monitor channel turns its own power supply to the MFP heater on. The MFP heater is then powered full on, − Senses an MFP and TAT sensor heater or control circuit failure
without automatic control of the heater element. − Senses if the faceplate is below a critical temperature
− Senses if there is TAT sensor heater power
Control and Monitor of the TAT Sensor Heater
The same input discrete that controls the MFP heat also controls the regulated heater power to the TAT sensor. When the
discrete input from the overhead panel (5000PM) to the smart probe is in the "on" state, the primary channel controls the
TAT sensor heater power. When the discrete input is in the "off" state, the primary channel turns the TAT sensor heater
power off.
The TAT can have high temperatures in still air when the TAT sensor heater power is not controlled. Too much heat
decreases the life of the TAT heater element. The smart probe controls the temperature of the TAT sensor to make the
service life of the TAT sensor better.
The smart probes apply full TAT sensor heater power when the left and right throttle angles are more than 30 degrees or
airspeed is more than 60 knots. The smart probe will turn off the TAT sensor heater power when Weight-On-Wheel is true
and airspeed is less than 45 knots and both left and right throttles angles are less than 30 degrees.
The TAT heater element current and applied voltage is measured to give the heater condition and to annunciate the
heater element failures.

determine when to switch on or off. They consist of a fine resistant wire with a positive temperature variation coefficient.
They are composed of fine long wires. They are laid as close as possible to the heating film for a minimal thermal lag and
located along the upper edge of the windshields with regard to cold or hot spots to satisfy requirements for the heating film
design. States of temperatures sensors of frontal windshields are sent to avionics via frontal SAB, D-box and WPS. If the
two states are failed, a CAS message is sent to crew.

Each WPS is in the “OFF” mode at power-up. The LH (L1001DG) / RH (R1001DG) WPS does not supply any of the
windshields.
Normal
This position is selected in case of icing or misting condition. The LH / RH WPS supplies:
− LH (L101SA) / RH (R101SA) front windshield via the dispatch box and the respective SAB
− LH (L102SA) / RH (R102SA) side windshield via the respective SAB, if the Ram Air Turbine (RAT) (4000PN) is
stowed
If the RAT (4000PN) is deployed, the LH / RH WPS stops supplying the LH (L102SA) / RH (R102SA) side windshield, in
order to limit the power consumption. In the normal mode the temperature of all the windshields is regulated by the WPS
according to the aircraft altitude.
“MAX”
This position is selected in case of important icing. The LH (L1001DG) / RH (R1001DG) WPS supplies only the LH
(L101SA) / RH (R101SA) front windshield, respectively, via the windshield de-icing dispatch box (2001DG) and the
respective SAB. In the “MAX” mode the temperature of the front windshields is regulated by the WPS according to the
aircraft altitude.
Back-up Mode
This mode is used in case of failure of the LH (L1001DG) or RH (R1001DG) WPS. It is selected with the windshield
"BACKUP" pushbutton (R9850PM) which has the two following positions:
“MAX LH”
This position is selected in case of the failure of the LH WPS. The sensors of the LH front windshield (L101SA) and the
power supply line are switched from the LH WPS (L1001DG) to the back-up WPS (M1001DG) via the windshield de-icing
dispatch box (2001DG). The main bus of the LH PPDB (5000PC) supplies the back-up WPS (M1001DG) via the
windshield de-icing 28 V DC dispatch contactor (3001DG). The back-up WPS supplies the LH front windshield only. The
LH side windshield is not supplied to limit power consumption. During the “MAX LH” mode the temperature of the LH front
windshield is regulated by the back-up WPS according to the aircraft altitude. The RH windshield de-icing system can be
in the normal mode.
“MAX RH”
This position is selected in case of the failure of the RH WPS. The sensors of the RH front windshield (R101SA) and the
power supply line are switched from the RH WPS (R1001DG) to the back-up WPS (M1001DG) via the windshield de-icing
dispatch box (2001DG). The main bus of the RH PPDB (6000PC) supplies the back-up WPS (M1001DG) via the
windshield de-icing 28 V DC dispatch contactor (3001DG). The back-up WPS supplies the RH front windshield only. The

WINDSHIELD RAIN REPELLENT SYSTEM LH Rain Repellent Solenoid Valve (L2008DG) Location
Overview
The Rain Repellent System is used to improve visibility through pilots' windshield in both following conditions:
− During A/C approach in rain condition
− During A/C ground operation in dew condition
− Backup for dry coating
Solenoid is located inside web
The system is controlled independently for each window (L/H and R/H front windshield) by two pushbutton switches
located on the overhead panel. Each time the left or the right switch is pressed, approximately 10cc of Rain Repellent fluid
is sprayed onto the windshield. During A/C approach the fluid is spread over the window by airflow and rain. During
ground operation, the fluid washes out the dew by gravity.
Components
Rain Repellent Can Assembly (3208DG)
The rain repellent fluid is packaged in a pressurized disposable type container, which is replaced when empty. This
container is called rain repellent can assembly (3208DG) Each rain repellent can assembly (3208DG) has a self-sealing
valve with a threaded boss for attaching the can assembly to the system receptacle of the rain repellent gauge assembly
(3108DG). The container has a capacity of 17.0 fluid ounces and is pressurized to 70 psi.
LH Rain Repellent Solenoid Valve (L2008DG) and RH Rain Repellent Solenoid Valve (R2008DG)
The rain repellent solenoid valves (L2008DG) and (R2008DG) are normally closed and electrically operated 28 VDC
valves. The rain repellent solenoid valves control the quantity of rain repellent fluid released to the rain repellent nozzles
(L1008DG) and (R1008DG) and are connected directly to them.

WINDSHIELD RAIN REPELLENT SYSTEM (CONTINUED)
Operation
The rain repellent system is controlled independently for each front windshield ((L101SA) and (R101SA)) by two
pushbuttons located on the overhead panel (5000PM):
− "LH" RAIN RPLNT Pushbutton (L9910PM)
− "RH" RAIN RPLNT Pushbutton (R9960PM)
Each time the left or right pushbutton is pressed, approximately 10 cc of rain repellent fluid is sprayed onto the front
windshield. During aircraft approach the fluid is spread over the window by airflow and rain. During ground operation, the
fluid washes out the dew by gravity. One spray of rain repellent ensures the visibility improvement through the associated
front windshield for one flight.
The Rain Repellent System consists of a pressurized container of rain repellent fluid called rain repellent can assembly
(3208DG), a container receptacle called rain repellent gauge assembly (3108DG) including a visual reservoir and a
pressure gauge, two solenoid valves LH rain repellent solenoid valve (L2008DG) and RH rain repellent solenoid valve
(R2008DG) including a time delay device, two nozzles assemblies LH nozzle installation assembly (L1008DG) and RH
nozzle installation assembly (R1008DG), plumbing and two pushbuttons.
The rain repellent can assembly (3208DG) and the rain repellent gauge assembly (3108DG) are installed in the cockpit.
The LH rain repellent solenoid valve (L2008DG), LH nozzle installation assembly (L1008DG), RH rain repellent solenoid
valve (R2008DG) and RH nozzle installation assembly (R1008DG) are mounted on the airplane front skin panel.
The rain repellent system is controlled independently for each front windshield ((L101SA) and (R101SA)) by two
pushbuttons "LH" RAIN RPLNT pushbutton (L9910PM) and "RH" RAIN RPLNT pushbutton (R9960PM) located on the
overhead panel (5000PM). The rain repellent fluid level is visible by the transparent reservoir of the rain repellent gauge
assembly (3108DG).
The rain repellent fluid pressure is indicated by a pressure gauge which has a green area and a yellow one. The rain
repellent fluid pressure is acceptable when it is in the green area. When rain repellent fluid pressure is in the yellow area,
the rain repellent can assembly (3208DG) needs to be replaced. The rain repellent can assembly (3208DG) is serviceable
when no presence of gas is visible in the transparent reservoir of the rain repellent gauge assembly (3108DG).
NOTE: If a gas bubble starts to show in the transparent reservoir of the rain repellent gauge assembly (3108DG),
there is sufficient fluid for 5 to 10 spraying shots.
If presence of gas is visible in the transparent reservoir, the rain repellent can assembly (3208DG) needs to be changed.

WINDSHIELD RAIN PROTECTION BY DRY-COAT
Overview
The four windshields are covered with a refurbishable coating of Dry Coat. Dry Coat is a durable hydrophobic film with
long-term rain-shedding properties. As long as the Dry Coat coating retains its intended efficiency, the use of water
repellent products is not necessary to maintain a clear vision under rain during ground or in-flight operations. The
chemical grafting to the glass provides Dry Coat with an excellent resistance to abrasion and weathering. When degraded
efficiency makes it necessary, the Dry Coat can be easily refurbished without removing the windshield.
Maintenance Considerations
“Cleaning of the Windshields and Windows” (excerpt from Task 56-0-00-100-801)
Dry Coat Kit
Cleaning of the Front Windshields
CAUTION: Only use the specified materials and cleaning agents. Other materials and cleaning agents can cause
damage to the surface protection of the components and the related area. Do not use the products
that follow:
Strong Acid, Bases, Cleaners with Fluorine Content, Abrasive Products, Methyl Ethyl Ketone.
1) Clean the outer surface of the front windshields (L101SA)/(R101SA) with a soft cloth soaked with the solution glass
cleaner AK10AE SOLUTION or GLASS PLUS SOLUTION or SPSPNH-01 SOLUTION, or with isopropyl alcohol.
2) Fully flush the surface of the front windshields (L101SA)/(R101SA) with water.
3) Dry with a soft cloth.
4) Make sure that the dry-coat is satisfactory (Refer to TASK 30-40-00-720-801).
1) Clean the outer and the inner surfaces of the side windshields (L102SA)/(R102SA) with a soft cloth soaked with
isopropyl alcohol.
2) Dry with a soft cloth.
Refurbishment
Unless inadequate cleaning procedures have been applied, Dry Coat is expected to remain effective in service for at least
6 months and for 1500 F/H expected on Falcon 7X. It shall be then refurbished to recover its original properties. The
Functional Check of the Windshield Dry Coat (Task 30-40-00-720-801)is done at each Basic Inspection (60 days).
Refurbishment of the Windshield Dry Coat (Task 30-40-00-910-801) may be required at that time.
Dry Coat is easy to refurbish in-situ. Removing the windshield from the aircraft is not necessary, and no more than two
operators are required. The time to refurbish a Dry Coat film does not exceed one hour and only the set of items
contained in the Sully Dry Coat Regeneration kit is required.

follow:
If the rain repellent fluid is in contact with clothes, replace clothes immediately.
Remove all protective clothes after maintenance of the rain repellent system is complete.
Do not retract the slats before they are cool (after 5 minutes approximately).
Do not test the wing anti-icing system, the engine air intakes, the S-Duct anti-icing system and the brake heating system
for more than one minute, and limit the engine setting to idle. If the test is longer than one minute or if the engines are set
above idle, it can cause structural damage to the slats, the air intakes and the S-Duct because of overheat.
