AIP Supplement for Mongolia

AIP AIRAC SUP

01/2018

Effective from 21 JUN 2018 to UFN

Published on 10 MAY 2018

AUTOMATIC DEPENDENT SURVEILLANCE - BROADCAST (ADS-B) IMPLEMENTATION IN MONGOLIA

1.  Introduction

1.1 The purpose of this AIRAC AIP Supplement is to inform about the plan of Civil Aviation Authority of Mongolia (CAAM) to implement ADS-B and provide advance notification to all stakeholders to ensure readiness.

1.2 Currently, there are ADS-B ground station facilities installed at 10 locations which cover most of the airspace of Mongolia.

2.  Implementation

2.1 CAAM has implemented ADS-B for air traffic situational awareness since 18 March 2016.

2.2 Starting from 21 June 2018 at 0000 UTC, ADS-B implementation for ATS surveillance separation will be applied in the airspace of Mongolia and during this period the carriage of ADS-B equipment for flight is optional.

2.3 Starting from 17 June 2021 at 0000 UTC, ADS-B will be used to provide ATS surveillance separation in the airspace of Mongolia and since then the carriage of ADS-B equipment for flight is mandatory.

3.  Area of application

3.1 The implementation of ADS-B in Mongolia will be applied in Class A airspace within ADS-B coverage between flight levels 6150m to 14600m.

3.2 ADS-B is used in ATS surveillance separation in the following ATC sectors:

  1. Sector Central;

  2. Sector Muren;

  3. Sector Gobi;

  4. Sector Dornod.

Note: For the information of above ATC sectors, please refer to ENR 2.1 of AIP Mongolia.

4.   Aircraft equipage for ADS-B Out

4.1 Carriage of ADS-B equipment for flights between flight levels 6150m and 14600m is optional. However with ADS-B only surveillance coverage, priority will be given to aircraft which are ADS-B equipped over non-equipped aircraft.

4.2 From 17 June 2021 at 0000 UTC, all aircraft flying within the airspace of Mongolia above flight level 6150m must carry serviceable ADS-B transmitting equipment (Mode S Transponder and GNSS source position) that meet the performance standards described in paragraph 4.3 below. Whilst aircraft flying below flight level 6150m, the carriage of ADS-B equipment remain optional.

4.3 Within ATC sectors described in paragraph 3.2, ADS-B transmitting equipment must be of an approved type meeting the specifications contained in Annex 10, Volume IV or that has been certified as meeting any of the following standards;

  1. European Aviation Safety Agency;

  2. Certification Considerations for the Enhanced ATS in Non - Radar Areas using ADS-B Surveillance (ADS-B-NRA) Application via 1090MHz Extended Squitter (EASA AMC 20-24), or

  3. Federal Aviation Administration – Advisory Circular No: 20-165A (or later versions Airworthiness Approval of Automatic Dependent Surveillance – Broadcast Out Systems, or

  4. the equipment configuration standards in Appendix XI of Civil Aviation Order 20.18 of the Civil Aviation Safety Authority of Australia.

4.4 If an aircraft carries ADS-B transmitting equipage which does not comply with the requirements of paragraph 4.3, the aircraft ADS-B equipage shall:

4.4.1 Deactivated; or

4.4.2 Set to transmit only a value of zero for the Navigation Uncertainty Category (NUCp) or Navigation Integrity Category (NIC) or Navigation Accuracy Category (NAC) or Source Integrity Limit (SIL).

Note:

  1. The requirement is met if the ADS-B transmitting equipment has a cockpit control that enables the pilot to turn the ADS-B transmissions on and off without disabling the ATC transponder.

  2. Deactivation of the ADS-B transmissions must not affect the continued operation of the Mode S transponder responses to interrogations.

  3. It is considered equivalent to deactivation if NUCp or NIC or NAC or SIL is set to continually transmit only a value of zero.

5.  Flight planning

5.1 Aircraft operators complying with the requirements stipulated in paragraph 4.3 are to indicate the appropriate ADS-B designator in Item 10 of the ICAO flight plan:

  1. E – Transponder - Mode S, including aircraft identification, pressure-altitude and ADS-B Out capability OR

  2. L – Transponder - Mode S, including aircraft identification, pressure-altitude, ADS-B Out and enhanced surveillance capability

together with:

  1. B1 ADS-B - out capability using 1090MHz extended squitter

    Or

  2. B2 ADS-B - out and - in capability using 1090MHz extended squitter

5.2 Aircraft Identification (ACID) not exceeding 7 characters must be accurately indicated in Item 7 of the ICAO flight plan and replicated exactly when set in the aircraft avionics (for transmission as Flight ID) as follows: either:

  1. The three-letter ICAO designator of the aircraft operator followed by the flight number (e.g. MGL223, CCA901, KAL867), when radiotelephony call sign consists of the associated ICAO telephony designator for the aircraft operator followed by the flight number (e.g. MONGOLIAN 223, AIR CHINA 901, KOREAN AIR 867),

    or

  2. The aircraft registration (e.g. JU1022, VHABC, 9V234) when the radiotelephony call sign consists of the aircraft registration.

 Note: ACID entered should not have any leading zeros unless it is part of the flight number as indicated in Item 7 of the ICAO flight plan. Hyphens, dashes or spaces are NOT to be used.

6.  ATC-pilot phraseology

Curcumstances

Phraseologies

1

Identification of aircraft

IDENTIFIED [position]

2

To request the capability of the ADS-B equipment

  1. ADVISE ADS-B CAPABILITY;

  2. *ADS-B TRANSMITTER (datalink);

  3. *ADS-B RECEIVER (datalink);

  4. *NEGATIVE ADS-B;

*Denotes pilot transmission

3

To request the operation of the IDENT feature

SQUAWK IDENT, or TRANSMIT ADS-B IDENT

4

To request reselection of aircraft identification

RE-ENTER [ADS-B or MODE S] AIRCRAFT IDENTIFICATION, or RE-ENTER FLIGHT IDENTIFICATION

5

To request transmission of pressure-altitude

TRANSMIT ADS-B ALTITUDE

6

To request termination of pressure-altitude transmission because of faulty operation

STOP ADS-B ALTITUDE TRANSMISSION [(WRONG INDICATION, or reason)]

7

To request termination of transponder and / or ADS-B transmitter operation.

Note: A pilot should respond with UNABLE then the controller should consider alternative solutions to the problem that do not remove the safety defenses of the other surveillance technologies. This might include manual changes to flight data, coordination with other controllers and/or change of assigned codes or call signs.

  1. STOP SQUAWK [TRANSMIT ADS-B ONLY];

  2. STOP ADS-B TRANSMISSION [SQUAWK (code) ONLY]

8

Termination of ADS-B service

IDENTIFICATION TERMINATED

9

ATS ADS-B surveillance system ground equipment degradation

ADS-B OUT OF SERVICE (appropriate information as necessary

7.  Contingency

7.1 In case of radar failure, ATC will provide surveillance separation by ADS-B.

7.2 ATC shall terminate the Surveillance separation and immediately provide the Procedural separation for aircraft, if the radar and ADS-B contact is lost from an ATC air situation display.

7.3 The pilot-in-command, upon awareness of an onboard ADS-B equipment failure, must inform ATC as soon as possible. ATC would then provide the necessary clearance to ensure separation with other flights operating in the delineated airspace.
