The service is provided in accordance with the provisions contained in Annex 15 - Aeronautical Information Services.

3.1  The aeronautical information is provided in the form of the Integrated Aeronautical Information Package consisting of the following elements:

- Aeronautical Information Publication (AIP);
- Amendment service to the AIP (AIP AMDT);
- Supplement to the AIP (AIP SUP);
- NOTAM and Pre-flight Information Bulletins (PIB);
- Aeronautical Information Circulars (AIC); and
- Checklists and lists of valid NOTAM.

NOTAM and the related monthly checklists are issued via the Aeronautical Fixed Service (AFS), while PIB are made available at aerodrome AIS units or website. All other elements of the package are distributed by air mail(for the lists of valid NOTAM by airmail or e-mail).

3.2  Aeronautical Information Publication (AIP)

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.

AIP Republic of Korea is published in three(3) volumes.

The AIP is published in a loose-leaf form with bilingual text (English and Korean) for use in international and domestic operations, whether the flight is a commercial or a private one.

3.3  Amendment service to the AIP (AIP AMDT)

Amendments to the AIP are made by means of replacement sheets. Two types of AIP AMDT are produced:

- regular AIP Amendment (AIP AMDT), issued in accordance with the established regular interval (ref. GEN 0.1) and identified by a light blue cover sheet, incorporates permanent changes into the AIP on the indicated publication date; and
- AIRAC AIP Amendment (AIRAC AIP AMDT), issued in accordance with the AIRAC system and identified by a pink cover sheet and the acronym -AIRAC, incorporates operationally significant permanent changes into the AIP on the indicated AIRAC effective date.

A brief description of the subjects affected by the amendment is given on the AIP Amendment cover sheet. New information included on the reprinted AIP pages is annotated or identified by a vertical line in the left or the right margin (or immediately to the left or the right) of the change/addition.

Each AIP page and each AIP replacement page introduced by an amendment, including the amendment cover sheet, are dated. The date consists of the day, month (by name) and year of the publication date (regular AIP AMDT) or of the AIRAC effective date (AIRAC AIP AMDT) of the information. Each AIP amendment cover sheet includes references to the serial number of those elements, if any, of the Integrated Aeronautical Information Package which have been incorporated in the AIP by the amendment and are consequently cancelled.

Each AIP AMDT and each AIRAC AIP AMDT are allocated separate serial numbers which are consecutive and based on the calendar year. The year, indicated by two digits, is a part of the serial number of the amendment, e.g. AIP AMDT 1/10; AIRAC AIP AMDT 1/10.

A checklist of AIP pages containing page number/chart title and the publication or effective date (day, month by name and year) of the information is reissued with each amendment and is an integral part of the AIP.

3.4  Supplement to the AIP (AIP SUP)

Temporary changes of long duration (three months and longer) and information of short duration which consists of extensive text and/or graphics, supplementing the permanent information contained in the AIP, are published as AIP Supplements (AIP SUP). 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 separated by information subject (General-GEN, En-route-ENR and Aerodromes-AD) and are placed accordingly at the beginning of each AIP Part. Supplements are published on yellow paper to be conspicuous and to stand out from the rest of the AIP. Each AIP Supplement (regular or AIRAC) is allocated a serial number which is consecutive and based on the calendar year, i.e. AIP SUP 01/10; AIRAC AIP SUP 01/10.

An AIP Supplement is kept in the AIP as long as all or some of its contents remain valid. The period of validity of the information contained in the AIP Supplement will normally be given in the supplement itself. Alternatively, NOTAM may be used to indicate changes to the period of validity or cancellation of the supplement.

The checklist of AIP Supplements currently in force is issued in the monthly printed plain-language list of valid NOTAM.

3.5  NOTAM and Pre-flight Information Bulletins (PIB)

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 significations/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 originated and issued for Incheon FIR and are distributed in five series identified by the letters A, C, D, G and H.

Series A. NOTAM containing information for the personnel concerned with international flight operations of general rules, airnavigation and communication facilities, airspace restrictions and activities, and international airports. Given international distribution only.

Series C. NOTAM containing information for the personnel concerned with flight operations of general rules, air navigation and communication facilities, and aerodromes. Given domestic distribution only.

Series D. NOTAM containing information for the personnel concerned with flight operations of airspace restrictions and activities. Given domestic distribution only

Series G. NOTAM containing information of the prediction of GPS Receiver Autonomous Integrity Monitoring(RAIM) outage of international aerodromes. Given international distribution only.

Series H. NOTAM containing information of the prediction of GPS Receiver Autonomous Integrity Monitoring(RAIM) outage of aerodromes. Given domestic distribution only.

SNOWTAM are originated for information concerning snow, ice, slush or standing water associated with snow, slush and ice on the movement area. SNOWTAM are prepared in accordance with Annex 15, Appendix 2, and are issued for the individual aerodrome with separate serial numbers.

Pre-flight Information Bulletins(PIB), which contain a recapitulation of current NOTAM and other information of urgent character for the operator/flight crews, are available at the aerodrome AIS units.

3.6  Aeronautical Information Circulars (AIC)

The Aeronautical Information Circulars (AIC) 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 or notification of an explanatory or advisory nature concerning technical, legislative or purely administrative matters. AIC are divided by subject and are issued in one series.

AIC is numbered consecutively on a calendar year basis. The year, indicated by two digit, is a part of the serial number of the AIC, e.g. AIC 1/10. A checklist of AIC currently in force is issued as an AIC once a year.

3.7  Checklist and list of valid NOTAM

A checklist of valid NOTAM is issued monthly via the AFS. A list of valid NOTAM will be posted on the Aeronautical Information Management(AIM) website(http://aim.koca.go.kr/xNotam/). it contains a plain language (in English) presentation of the valid NOTAM and information about the number of the latest issuedAIP AMDT, AIRAC AIP AMDT, AIP SUP and AIC as well as the numbers of the elements issued under the AIRAC that will become effective or, if none, the NIL AIRAC notification.

4.1  In order to control and regulate the operationally significant changes requiring amendments to AIP, charts, etc., such changes, whenever possible, will be issued on predetermined dates according to the AIRAC System. This type of information will be published as an AIRAC AIP AMDT or an AIRAC AIP SUP.

4.2  The table below indicates AIRAC effective dates for the coming years. AIRAC information will be issued 42 days before the effective date so as to reach recipients at least 28 days in advance of the AIRAC effective date. When an aeronautical information is issued in accordance with AIRAC procedures, Trigger NOTAM will be issued giving a brief description of the contents, the effective date and the reference number to the amendment or supplement. This NOTAM will come into force on the same effective date as the amendment or supplement and remain valid in the pre-flight information bulletin for a period of 14 days.

4.3  If no information was submitted for publication at the AIRAC date, a NIL notification will be issued by NOTAM not later than one AIRAC cycle(28 days) before the AIRAC effective date concerned.
