1.1 INTRODUCTION
This manual contains information regarding the physical, mechanical and electrical
characteristics, as well as installation information pertaining to the Ryan TCAD Model
ATS-9000.      For maintenance and repair information, contact Ryan International
Corporation.
1.2         PRODUCT DESCRIPTION
The Ryan TCAD (Traffic and Collision Alert Device) is an on-board traffic display
product used to identify and display information regarding nearby transponder equipped
aircraft. From Mode C transponder replies, TCAD determines relative altitude and range
of nearby aircraft.      Aircraft with non-Mode C transponders can provide range
information. The Ryan TCAD will not detect aircraft without transponders. TCAD,
within defined limits, creates a shield of airspace around the aircraft, whereby detected
traffic cannot penetrate without generating an alert. The shield size is selectable for
various phases of flight, and is adjustable by the pilot.
TCAD uses a cockpit display for traffic information. An audible tone and an optional
annunciator light are provided to alert the pilot. Range is displayed in indicated Nautical
Miles(iNM), determined from the alrival amplitude of the threat transponder signal.
Relative altitude is displayed in hundreds of feet, and is determined from comparison of       ‘-J
the Mode C replies with the host altitude encoder. Installation consists of a single or dual
Display units, a remote mounted processor, a top-mounted L-band antenna and a
Transponder Coupler for each transponder. An optional second, belly mounted, antenna
and associated Dual Antenna Module is available.
Code and Altitude - TCAD will display the identity code and altitude of detected
traffic.
Indicated Altitude - TCAD provides for MSL corrected altitude (or Flight Level) of
the host aircraft.
Altitude Alert -       Provides tones for approaching a target altitude, and to inform the
pilot of inadvertent changes in cruise altitude.
TCAD will display multiple aircraft inside the selected shield. The TCAD is advisory
only, and is a back-up to the “SEE-AND-AVOID” concept and the ATC radar
environment.                                                                                   i/

2.1 GENERAL
The Ryan TCAD should be installed according to this manual and AC 43.13-1A and -2A.
Cable harnesses and mechanical supports must be fabricated by the installing agency to
these requirements. This section contains interconnect diagrams, mounting dimensions,
antenna placement and other information pertaining to installation.
Re fer to Section IV for checkout and Customer Care checklist.
Exercise care when unpacking the equipment. Make a visual inspection of the unit for
evidence of damage incurred during shipment. If a claim for damage is to be made, save
the shipping container to substantiate the claim. The claim should be filed with the
transportation company. Retain the container and packaging material after the equipment
has been removed should equipment storage or reshipment become necessary.
The onboard transponder(s) must have suppression capability (often called DME
suppression). A transponder is not required for proper operation of the TCAD.
An altitude encoder is required for proper operation of the TCAD. Encoders that meet
the performance requirements of TSO C88a have the proper output, and can interconnect
with the TCAD paralleled on the output without degrading the performance of the
encoder (see Figure l-l).
In most circumstances, the TCAD should be connected to the encoder which is
connected to the transponder.
2.4 SUPPRESSION
TCAD is connected to the transponder(s) via the suppression line. When TCAD and the
transponder are the only devices on the line, TCAD is connected directly to the
suppression input of the transponder(s) as illustrated by Figure 2-6.
DME suppression is not required for TCAD operation. If the DME is not on the
suppression line, it is not necessary to connect it.
TCAD is compatible with both mutual and unidirectional suppression systems. Only
transponders with suppression can be used. The following table lists the availability of
suppression for various transponders. Not all transponder suppression configurations
conform to ARINC standards. See Figure 2-12 for conformance information.
    The Dual Antenna Module is a switching device used to provide TCAD with signals
    from the primary top antenna and the secondary bottom antenna. The Dual Antenna
    Module is optional. A five volt source, logic line, and ground for the Dual Antenna
    Module come from the TCAD processor.
               NOTE:      Insure that the mounting location for the Dual Antenna Module is
                          accessible (must be accessed for checkout) and at a location that
                          provides a good ground. Normally, the mounting tray or avionics
                          rack is not a good ground.
    The Transponder Coupler is a passive device used to provide TCAD with an indication
    that the transponder has fired. The information is used in signal processing and for
    Performance Monitoring.
-   When routing the Antenna Cable, make the run as short as possible, and avoid any
    cabling that may contain excessive EMI, such as such as DME, transponder cables,
    suppression lines from other equipment or high-current power cables.
    When mounting the Transponder Coupler, use the Type-N connectors provided. Use of
    BNC to Type-N adapters can increase the VSWR in the transponder cabling. Check the
    output frequency of the transponder at its antenna after installing the Coupler to insure
    that a standing wave has not been introduced.
               NOTE:      Insure that the mounting location for the coupler is accessible and
                          at a location that provides a good ground. Normally, the mounting
                          tray or avionics rack is non a good ground.
2.6 COOLING
    Elevated operating temperatures reduce reliability. Forced air cooling is not required,
    however, sufficient space around the display to allow adequate convective cooling is
    desirable.
    Every Ryan TCAD is checked for operation before shipment. Occasionally however, a
    unit may not function after shipment. To avoid undue inconvenience, an initial bench
    check is appropriate. See Paragraph 4.3 for this procedure.
w
Listed below are factors and suggestions to consider before installing the Ryan TCAD.
Close adherence to these suggestions will assure optimum performance.
           NOTE:      Insure that the retaining screws used to mount the Coupler do not
                      interfere with fully tightening the N-connectors on the Coupler.
All wiring should be secured to prevent chafing and faulty connections. Refer to
Advisory Circular 43.13-2A.
           NOTE: Wiring precautions.
           A.   Observe proper cable routing, ie. avoid tie-wrapping transponder output
                cable with TCAD antenna. Also, do not tie-wrap cable bundle so tight
                as to deform cables. Separate coupler line and TCAD antenna from
                other transmitting cables by as much as possible.
           B.   Insure that all connections are sound, ie. avoid frayed and exposed
                shield.
           NOTE:      Route the Coupler cable away from possible sources of EM1
                      such as DME, transponder cables, suppression lines from other
                      equipment or high-current power cables.
           A.   Assemble a cable (see paragraph 1.6 E. for type) from the transponder
                RF output to the input of the Transponder Coupler marked XPDR.
                Install the type-N connectors provided (see Para. 2.7 and Figure 2-5).
A well fabricated antenna cable is very important to minimize signal loss. See Figure l-2
for recommended types and lengths.
             NOTE:            The antenna should be mounted on top of the fuselage
                                                                        I       ” (see
                                                                                   x
                              Figure 2-2).
             A.   The L-band antenna must be located on a top surface of the
                  aircraft, as high and as far forward as practical. Mount close to the
                  aircraft centerline, and in a vertical position when the aircraft is in level
                  flight. Generally, the antenna mounts above the cockpit, as far forward
                  as practical (See Figure 2-2).
             B.   The antenna should be mounted at least 12-inches from access panels,
                  doors, or other openings to provide a good ground plane. To the extent
                  practicable, mount the antenna so that the base is horizontal when the
                  aircraft is in cruise attitude.
             G.   Route the cable avoiding sharp bends and using strain relief. Secure as
                  necessary to prevent chafing. Avoid routing antenna cables with
                  electrical cables.
                                     RECOMMENDED PRIMARY
                                       ANTENNA LOCATION
           CAUTION: Before drilling any mounting hole for the antenna, determine
                          that there is adequate clearance inside the fuselage for the
                          antenna and cable connector.
           B.    Sand the inside area of the aircraft where the doubler plate will be
                 mounted to assure proper RF bonding.
           C.    Cleanse the sanded metal of any residue, using a solvent such as MEK
                 or Trichloroethylene. Then apply Alodine No. 1001 (or equivalent) for
                 corrosion protection.
           I.    Inspect coaxial cable connector for proper center contact, then connect
                 securely to the antenna.
3.1 GENERAL
A tone and an optional annunciator can be used to call attention to a detected threat that
has penetrated the Air Traffic Shield. Additionally, when the Altitude Alert is engaged, a
distinctive short tone is generated to call attention to either arrival at a target altitude, or
an altitude deviation.
TCAD computes relative altitude and range of threats using transponder replies from
nearby Mode C equipped aircraft. Aircraft with non-Mode C transponders can provide
range information.
Relative altitude information is derived from decoding the Mode C replies from nearby
aircraft, and comparing the data with the encoded altitude information provided by the
host aircraft. Range information is determined from the arrival amplitude of the digital
transponder signal. TCAD displays the range in indicated Nautical Miles (iNM).
     The volume of airspace in which traffic should be detected changes with the traffic
     density. When traffic is light, and aircraft are at cruising speeds, a large area of airspace
     should be monitored. In higher density airspace, when the pilot is more alert for traffic
     and speeds are limited, a smaller surveillance volume is generally appropriate.
     The concept of an Air Traffic Shield is used to describe an adjustable volume of airspace,
     controlled by the pilot to display potential threats, yet prevent extraneous traffic from
     being displayed.
     The Air Traffic Shield is a slice of airspace of specified radius and specified height above
     and below the aircraft, where a detected threat normally cannot enter without generating
     an alert.
     The Ryan TCAD provides three quickly selectable and Pilot programmable shield
     volumes, designated as the Enroute (ENRT), Standard (STD), and Terminal (TRML)
     modes. See Paragraph 1.3 for Shield limits.
     The TCAD displays threat data when an intruder is detected near the shield, and a tone is
     generated when the threat enters the shield. The Mute button may be used to suppress
     the tone for a specified duration.
d    To avoid nuisance indications on the ground, a special sub-mode of the Terminal Mode,
     called the Ground Mode, can be automatically activated. The Ground Mode has the same
     dimension as the Terminal Mode shield size, suppresses the display of traffic at and
     below 100 feet above the host altitude, and mutes all alert tones. Thus data available
     from traffic near the airport is displayed, and aircraft on the ground are not displayed.
     A transition symbol of “DP”, for departure is shown in the Mode cell during the
     transition from the 200 foot level to the full dimension of the Terminal shield.
     The Approach Mode can be activated before landing to eliminate tones caused by aircraft
     on the ground as the TCAD-equipped airplane approaches the runway.
     In order to use the Approach Mode before landing, TCAD must be supplied with the
     destination elevation.
     Anytime before landing, the pilot can access the mode by pressing the MUTE and TRML
     buttons (thus Muting the Terminal). The status window will show APCH. The top line
     of the TCAD display will show FldElev:, and the lower line will show >>xxOOft (xx is
     normally the elevation previously set into this mode). The up and down buttons can be
     used to enter the destination field elevation. Pressing the MUTE button again restores
     TCAD to the previously selected mode (or eight seconds elapsed time will return TCAD
     to the previously selected mode). When the base of the Terminal shield gets within 100
     feet of the selected field elevation, TCAD automatically enters the Approach Mode, as

3.9 PROGRAMMING
When completing an installation, the factory settings should be checked, and the
programming functions should be used to adjust the settings as necessary (see Factory
Settings Paragraph 1.4). The following. paragraphs describe the programming functions.
To engage a programming function, the appropriate button is pressed twice. When this is
done, the current setting is displayed. The up and down buttons can be used to adjust the
displayed parameter. To select the next parameter, the appropriate button is pressed
again, When each parameter has been considered, TCAD returns to collision alert
operation. In all cases, if no button is pressed for about 8 seconds when in a
programming mode, the TCAD will return to collision alert operation.
Depress the selected button (TRML, STD, or ENRT) twice. The shield height in
hundreds of feet will be displayed. To change the height, press the A or V buttons.
Depress the selected button again for shield radius adjustment. Depress the mode button
once more to return TCAD to normal operation.
      If no button is pressed for 8 seconds, the TCAD will automatically return to collision
      alert operation.
      The sequence for tone related set up is as follows:
      Press the Trml and Code buttons simultaneously.             The previously programmed
      temperature will be displayed on the right. Use the up and down buttons to set the actual
      outside air temperature and read the Density Altitude on the left.
      Press the v and A buttons simultaneously. The previously programmed altitude will be
      displayed. Use the up and down buttons to set the selected altitude. Pressing the v and
      A buttons again will engage the Altitude Alert. See the Pilot’s Handbook for more
      information.
      The host transponder reply is sensed through the transponder coupler. When a reply is
      detected, the signal received through the antenna is coarsely measured for proper
      amplitude. If the amplitude is at least 50% of the power required for overload of the
      receiver, the test result is considered satisfactory. If the amplitude is less than 50%, then
      a failure is declared.
      A failure to receive signals will allow partial operation of the equipment. “Signal Fail” is
      momentarily displayed on the TCAD, a tone is generated and the TCAD collision alert
      functions are deactivated. All other functions are available, including altitude display
      and altitude alert. After the alert, the equipment will show the altitude on the top portion
      of the display, and “SgnlFAIL” on the lower portion.
When the Pilot Initiated test is activated (by pressing the Mute and Up buttons), the
following is displayed:
1. Testing Remote.
8. Testing Display.
4.1 GENERAL
       To check the computer functions in TCAD. This test may be used for initial
       testing or for troubleshooting.
       Ramp Test:
       To check the function of the TCAD, to confirm proper operation
       of the host transponder and altitude encoder with TCAD on, to verify proper
       computer receiver interface and to check the interconnections with other
       equipment.
4.3.2       Test:
CAUTION:       Check power level and wiring before applying power.
A.          Depress the Power Switch on the TCAD. After initialization, the display will
            show 6700 m SRCHNG (TCAD will show field elevation if the test is
            performed in the aircraft). The letter “G” will appear in the lower right cell
            indicating operation in the Ground mode.
            NOTE:     If the automatic Ground Mode setting has been changed, TCAD
                      will initialize and operate in the last mode selected.
D.          Depress the ENRT button. The mode indicator will indicate the ENRT
            Mode (See Display Symbols, Figure 3-l).
E.          Depress the Mute button. A small upper case “M” will appear on the display
            for about 30 seconds.
(continued)
G.          Depress the ENRT and STD buttons simultaneously. The letter “U” will
            appear in the lower right cell. (“U” will not appear if traffic is within ENRT
            shield).
H.          Depress the STD mode button. The “U” will be replaced by the indicator for
            STD mode.
I.          Depress Mute twice. Verify audio is present and at an acceptable level.
            (When installed in the aircraft).
4.4.1       Setup:
A.         Place the aircraft in an area where signal reflections can be minimized, and
           place the transponder test set in position to interrogate the host transponder.
B.         Set the transponder test set for Mode A/C and interrogate the host
           transponder.
After applying power to the aircraft, turn on all avionics, then depress the Power Switch
on the TCAD. After initialization and adjusting the altimeter setting, the display will
show field elevation +lOO feet and “SRCHNG” (See Figure 3-l). “G” will appear in the
lower right cell, indicating TCAD operation in the Ground Mode.
C.         Depress the TEST buttons (CODE and ENRT). Continue to interrogate the
           host transponder.
(Continued)
D. After a short processing time, TCAD will show the following sequence:
            1. Testing Remote.
            2. A single threat warning tone is sounder?.
            3. ALT CHK:        (check for correct altitude display)
            t. iz: (X2: (check for correct squawk)
                           *   OK or fail
            6: SYS CHK:.       OK or fail
            7. COM LINK 100% (should be 95% or greater)
            8. Testing Display.
            9. The display will then show the software versions.
            NOTE: This test can be conducted while flying.
If ALT or SQK are decoded incorrectly, conduct the test again, possibly at a different
location on the ramp, since reflections can influence these tests. If the ALT and SQK are
never received, check that the transponder is transmitting, and that the test location is not
in a highly reflective area. If these are OK, check for and eliminate possible sources of
EMI on the Coupler line.
If REC check indicates failure, check the antenna cables and check for and eliminate
possible sources of EMI on the Coupler line. If REC check still fails, contact the
Factory.
If COM LINK is less than 95%, check the display to processor interconnect lines for
sources of EMI. If COM LINK percentage cannot be improved to 95% or more, contact
factory.
A.          Continue to interrogate the host transponder, and conduct this test using the
            Ramp Test set up, paragraph 4.4.1,
B.          Slowly press each button on the TCAD, allowing the display to return to
            either SRCHNG or a traffic display between button presses. The display
            should immediately respond to each button input.
            NOTE:     If the button response is very slow, check for and eliminate sources
                      of EMI along the Cable between the Transponder Coupler and the
                      TCAD.
(Continued)
B. When the display shows “Testing Display”, press the UP arrow and MUTE.
     C.         TCAD will then pelfonn a 90 second CRC test of the display. A horizontally
                oriented number will count down as the test is conducted. The test will
                conclude with the software version levels indicated.
     A.         Continue to interrogate the host transponder, and conduct this test using the
                Ramp Test set up per subparagraph 4.4.1.
                Note: Some signal attenuation (Range variation) may occur when using
                      the bottom antenna only.
To perform checks of the TCAD on the bench, use the Connectors supplied for the bench
harness, and wire the connectors as follows:
A.          Wire connector P901 by grounding pins 3 and 9. This will provide a
            simulated altitude of 6700 feet.
B.          Wire power, ground and the display lines between the Display and the
            Processor as shown in Figure 2-6.
E.          The BNC connections (Coupler, Suppression or Antenna) are not needed for
            TCAD operation on the bench.
