1.  Responsible service

2.  Area of responsibility

The Aeronautical Information Services Division is responsible for the collection, processing and dissemination of information for the Ulaanbaatar FIR.

3.  Aeronautical publications

1. Aeronautical Information Publication (AIP), including Amendments and Supplements;

2. Aeronautical Information Circulars (AIC);

3. Aeronautical charts;

4. NOTAM;

5. Digital data sets.

The AIP is the basic aviation document intended primarily to satisfy international requirements for the exchange of permanent aeronautical information and long duration temporary changes essential for air navigation.

The AIP Mongolia is published in loose leaf paper form and electronic form (eAIP) in Mongolian and English. The AIP in electronic form (eAIP) is issued both on CD and internet (www.ais.mn).

AIP amendment contains new information of a lasting character to be included in the AIP. Two types of AIP AMDT are produced:

1. Regular AIP Аmendment (AIP AMDT)

   Regular AIP Amendment (AIP AMDT), issued in accordance with the established regular interval (ref. GEN 0.1.4) and identified by a light blue cover sheet, incorporates permanent changes into the AIP on the indicated publication date;

2. AIRAC AIP Amendment (AIRAC AIP AMDT)

   AIRAC AIP Amendment (AIRAC AIP AMDT), issued in accordance with the AIRAC system and identified by a pink cover sheet and acronym-AIRAC, incorporates operationally significant permanent changes into the AIP on the indicated AIRAC effective date.

Each AIP AMDT and AIRAC AIP AMDT are allocated separate serial numbers which are consecutive and based on the calendar year.

New information included on the reprinted AIP pages is annotated by a vertical line in the left or right margin of the change. Removal of information from the reprinted AIP pages is annotated by horizontal line in the left or right margin of the removed information.

A checklist of AIP pages containing page number and the publication or effective date of the information is reissued with each regular AIP Amendment.

Temporary changes of long duration (three months or longer) or information of short duration which contains extensive text and/or graphics shall be published as AIP Supplements. Operationally significant temporary changes to the AIP are published in accordance with the AIRAC system and its established effective dates and are identified clearly by the acronym AIRAC AIP SUP.

AIP Supplements are published on yellow paper and are kept in the AIP as long as all or some of its contents remain valid.

Each AIP Supplement (regular or AIRAC) is allocated a serial number which is consecutive and based on the calendar year.

Aeronautical Information Circulars contain information on the long-term forecast of any major change in legislation, regulations, procedures or facilities, information of a purely explanatory or advisory nature liable to affect flight safety; and information of an explanatory or advisory nature concerning technical, legislative or purely administrative matters.

AIC are issued in two series (A and C). AIC Series A is given international distribution and is issued in English and Mongolian. AIC Series C is given national distribution and is issued in Mongolian.

Each AIC is numbered consecutively within each series on a calendar year basis.

NOTAM contain information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential for personnel concerned with flight operations. The text of each NOTAM contains the information in the order shown in the ICAO NOTAM Format and is composed of the signification/uniform abbreviated phraseology assigned to the ICAO NOTAM Code complemented by ICAO abbreviations, indicators, identifiers, designators, call signs, frequencies, figures and plain language.

NOTAM are distributed in three series identified by the letters A, C and special series S (SNOWTAM) only in English.

Each NOTAM is assigned a serial number preceded by a letter indicating the series. The serial number starts first NOTAM of every year with number 0001.

Series A. Information concerning general rules, en-route navigation and communication facilities, airspace restrictions and activities taking place within FIR and information concerning the following aerodromes:

1. ZMCD DORNOD/Choibalsan;

2. ZMCK ULAANBAATAR/Chinggis khaan;

3. ZMUB ULAANBAATAR/Buyant-Ukhaa;

4. ZMUL BAYAN-ULGII/Ulgii;

5. ZMKD KHOVD/Khovd;

6. ZMMN KHUVSGUL/Muren.

Series C. Information on all aerodromes, except for aerodromes published in Series A.

Series S (SNOWTAM). A special series NOTAM given in a standard format providing a surface condition report notifying the presence or cessation of hazardous conditions due to snow, ice, slush, frost, standing water or water associated with snow, slush, ice or frost on the movement area.

NOTAMs are distributed by the aeronautical fixed service (AFS).

NOTAM checklist shall be issued for each series and it contains following parts.

Part 1: starts with “CHECKLIST” and followed by all valid NOTAM number classified by year;

Part 2: starts with "LATEST PUBLICATION" and followed by the numbers of latest AIP AMDT and digital data set;

Part 3: starts with “CHECKLIST OF AIP SUP AND AIC” and followed by numbers of all valid AIP SUP and AIC.

NOTAM checklist for A series shall only contain A series AIC checklist, NOTAM checklist for C series shall only contain C series AIC checklist.

NOTAM checklist will issued via the aeronautical fixed service (AFS).

The AIP Mongolia can be obtained from the Aeronautical information services division.

4.  AIRAC system

AIRAC information will be issued so that the information will be received by the user not later than 28 days, and for major changes not later than 56 days, before the effective date.

5.  Pre-flight information service at aerodromes

The pre-flight information bulletin (PIB) is a presentation of current NOTAM of operational significance and prepared normally 2 hours prior to flight in the form of plain-language.

The PIB for departing flights from Chinggis khaan international airport and Buyant-Ukhaa international airport shall be prepared 2 hours prior to the flight, publish to AIS division website. And deliver by e-mail to requested users.

Depending on the requirements of users, following types of PIB can be prepared:

1. Aerodrome PIB

   Aerodrome PIB contains NOTAM and SNOWTAM related to the selected aerodromes.

2. Normal route PIB

   Normal route PIB is a bulletin based on a generalised route as contained in the flight plan. It contains NOTAM and SNOWTAM related to the crossed FIRs and selected aerodromes.

3. Narrow route PIB

   Narrow route PIB is a bulletin based on the planned route from the related flight plan, and includes NOTAM and SNOWTAM related to the width of the corridor based on planned route as contained in the flight plan.

4. Special area PIB

   Special area PIB contains NOTAM and SNOWTAM inside user-defined area.

1. to obtain the relevant PIB according to the individual input criteria;

2. to obtain flight status;

3. to submit flight plan.

The purpose of post-flight information is to ensure that inadequacies of facilities essential to the safety of flight operations, and the presence of wildlife on or around the airport constituting a potential hazard to aircraft operations, observed by flight crews during the flight, are reported without delay to the authority responsible for those facilities.

Post-flight information service is provided at the Chinggis khaan and Buyant-Ukhaa aerodromes.

Post-flight report form is available on the AIS web site (https://www.ais.mn/preReport) for the electronic submission. Printed forms can be delivered in person of the AIS unit at Chinggis khaan international airport or send an email to aisbof@ncac.mn.
