Aeronautical Information Publication (AIP)
Aeronautical Information Publication (AIP) represents the basic aeronautical information document intended primarily to satisfy international requirements for the exchange of permanent aeronautical information and long duration temporary changes essential for the safe conduct of international and domestic air traffic.
The AIP consists of three parts:
- General (GEN): national regulations and requirements, description of air navigation services (AIS, ATM, CNS, MET, SAR), charges for aerodromes/heliports and air navigation services;
- En-route (ENR): general rules and procedures, Instrument/Visual Flight Rules (IFR/VFR), airspace classification and description, ATS airspace, ATS routes, radio navigation aids/systems, navigation warnings, en-route charts and index charts; and
- Aerodromes (AD): general conditions for use of aerodromes, detailed information on aerodromes, including aerodrome charts.
AIP Amendments (AIP AMDT) in printed form consist of new pages which need to be inserted and pages which serve as replacement pages. AIP Amendments which are in the electronic format (CD or Internet) are not distributed as separate packages, but their content is included in the AIP content.
There are two types of AIP Amendments:
- regular AIP Amendment (AIP AMDT) – contains permanent changes to the AIP which shall become effective on the indicated publication date, and is issued at regular 4-week intervals, one day after an AIRAC effective date (the cover sheet is white);
- AIRAC AIP Amendment (AIRAC AIP AMDT) – contains operationally significant permanent changes to the AIP which shall become effective on the indicated AIRAC effective date, and is issued in accordance with the AIRAC system (the cover sheet is pink).
Temporary changes of long duration (three months or longer) and information of short duration which contains extensive text and/or graphics, supplementing information of permanent nature 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 the determined effective dates, and are identified clearly by the acronym AIRAC AIP SUP.
The period of validity of the information contained in the AIP SUP, if the period is defined, is normally given in the supplement itself. Alternatively, possible changes concerning the period of validity or contents may be issued by NOTAM.
AIP Supplements in printed form are inserted at the beginning of the AIP and form the first section in the AIP binder. AIP SUP pages are yellow so as to be conspicuous and easily distinguished from the rest of the AIP.
The checklist of valid AIP SUP is issued through the Monthly list of valid NOTAM Series A and C.
