PART 139

CAA Consolidation

Aerodromes - Certification, Operation and Use

Civil Aviation Authority of Mongolia

 Civil Aviation Rules Part 139

DESCRIPTION
Part 139 provides the regulatory requirements relating to-
 the certification and operation of aerodromes;
 the security measures applicable to aerodromes;
 the use of aerodromes by aircraft operators;
 the provision of UNICOM and AWIB services.
Part 139 adopts the standard layout for the rule parts relating to the certification of
organisations. The layout prescribes specific requirements for the certification (entry
standards), operation (continued operations), and safety audit (surveillance) of
aerodromes. Part 139 also details the requirements for security measures to be
complied with by the aerodrome certificate holder.

This document is the current consolidated version of Part 139 produced by the
Civil Aviation Authority, and serves as a reference only. It is compiled from the
official ordinary rules that have been signed into law by the Minister of Road and
Transport. Copies of the official rule and amendments as signed by Minister may
be obtained from the Civil Aviation Authority or may be downloaded from the

taken, the risks to aviation safety will be managed to a level at which no
determination will be required; and
(3) consult with any other party and aviation industry participant, that the Director
considers may be appropriate, to determine if a determination is required.

it appropriate, use an aeronautical study that was prepared under Part 157 instead of
an aeronautical study required under rule 139.21.

F.2. Marking of objects

(a) All fixed objects to be marked must, whenever practicable, be coloured, but if this
is not practicable, markers or flags must be displayed on or above them, except that
objects that are sufficiently conspicuous by their shape, size, or colour need not be
otherwise marked.
(b) All mobile objects to be marked must be coloured or marked with display flags.

F.3. Use of markers

Markers displayed on or adjacent to objects must be located in conspicuous positions
so as to retain the general definition of the object and must be recognizable in clear
weather from a distance of at least 1000 m for an object to be viewed from the air
and 300 m for an object to be viewed from the ground in all directions in which an
aircraft is likely to approach the object. The shape of markers must be distinctive to
the extent necessary to ensure that they are not mistaken for markers employed to
convey other information, and they must be such that the hazard presented by the
object they mark is not increased.

F.4. Use of flags

(a) Flags used to mark objects must be displayed around, on top of, or around the
highest edge of, the object. When flags are used to mark extensive objects or groups
of closely spaced objects, they must be displayed at least every 15 m. Flags must not
increase the hazard presented by the object they mark.

12.Jun.2019 61
 Civil Aviation Rules Part 139

(b) Flags used to mark fixed objects must not be less than 0.6 m square and flags
used to mark mobile objects, not less than 0.9 m square.
(c) Flags used to mark mobile objects must consist of a chequered pattern, each
square having sides of not less than 0.3 m. The colours of the pattern must contrast
each with the other and with the background against which they will be seen. Orange
and white or alternatively red and white must be used, except where such colours
merge with the background.

F.5. Lighting of objects

(a) The presence of objects which must be lighted, as specified in Appendix F.1,
must be indicated by low-, medium- or high-intensity obstacle lights, or a combination
of such lights.
(b) Type C low-intensity obstacle lights must be displayed on vehicles and other
mobile objects excluding aircraft.
(c) Type D low-intensity obstacle lights must be displayed on follow-me vehicles.

A closed marking must be displayed on a runway or taxiway, or portion thereof,
which is permanently closed to the use of all aircraft.

G.2. Non-load-bearing surfaces

surfaces which cannot readily be distinguished from load-bearing surfaces and
which, if used by aircraft, might result in damage to the aircraft must have the
boundary between such areas and the load-bearing surface marked by a side stripe
marking.

G.3. Unserviceable areas

Unserviceability markers must be displayed wherever any portion of a taxiway, apron
or holding bay is unfit for the movement of aircraft but it is still possible for aircraft to
bypass the area safely. On a movement area used at night, unserviceability lights
must be used.

Appendix H - Electrical Systems

H.1. Power supply systems for air navigation facilities

(a) Adequate primary power supply must be available at aerodromes for the safe
functioning of air navigation facilities.
(b) For aerodromes that are referred to in rule 139.5(aa)(1), the design and provision
of electrical power systems for the aerodrome visual and radio navigation aids must
be such that an equipment failure will not leave pilots with inadequate visual and non-
visual guidance or misleading information.

H.2. Visual aids

(a) For a precision approach runway, a secondary power supply capable of meeting
the requirements specified in Table H-1 for the appropriate category of precision
approach runway must be provided. Electric power supply connections to those
facilities for which secondary power is required must be so arranged that the facilities
are automatically connected to the secondary power supply on failure of the primary
source of power.
(b) For a runway meant for take-off in runway visual range conditions of less than
800m, a secondary power supply capable of meeting the relevant requirements of
Table H-1 must be provided.

H.3. System design

(a) For a runway meant for use in runway visual range conditions of less than 550 m,
the electrical systems for the power supply, lighting and control of the lighting
systems included in Table H-1 must be so designed that an equipment failure will not
leave the pilot with inadequate visual guidance or misleading information.
(b) Where the secondary power supply of an aerodrome is provided by the use of
duplicate feeders, such supplies must be physically and electrically separate so as to
ensure the required level of availability and independence.
(c) Where a runway forming part of a standard taxi-route is provided with runway
lighting and taxiway lighting, the lighting systems must be interlocked to preclude the
possibility of simultaneous operation of both forms of lighting.

H.4. Monitoring
Where lighting systems are used for aircraft control purposes, such systems must be
monitored automatically so as to provide an indication of any fault which may affect
the control functions. This information must be automatically relayed to the ATS unit.
