Inaviation, anAeronautical Information Publication (orAIP) is defined by theInternational Civil Aviation Organization (ICAO) as a publication issued by or with the authority of a state and containingaeronautical information of a lasting character essential toair navigation.[not verified in body] It is designed to be a manual containing thorough details of regulations, procedures and other information pertinent to flying aircraft in the particular country to which it relates. It is usually issued by or on behalf of the respective civil aviation administration.
The structure and contents of AIPs are standardized by international agreement through ICAO. AIPs normally have three parts – GEN (general), ENR (en route) and AD (aerodromes). The document contains many charts; most of these are in the AD section where details and charts of all publicaerodromes are published.
AIPs are kept up-to-date by regular revision on a fixed cycle. For operationally significant changes in information, the cycle known as theAIRAC (Aeronautical Information Regulation And Control) cycle, first introduced in 1964,[1] is used: revisions are produced every 56 days (double AIRAC cycle) or every 28 days (single AIRAC cycle). These changes are received well in advance so that users of the aeronautical data can update theirflight management systems (FMS).For insignificant changes, the published calendar dates are used.
In some countries the AIP is informally known as theAirman's Manual or theAir Pilot.
Not all countries publish AIPs, particularly in Africa.
EUROCONTROL has published a specification for an electronic AIP (eAIP).[2] The eAIP Specification aims to harmonise the structure and presentation of AIPs for digital media.[3] In this respect, a digital AIP is a digital version of the paper AIP, usually available inPDF format, while an electronic AIP is available in PDF as well as other formats, more suitable for reading on the screen and for electronic data exchange. Many countries around the world provide digital AIPs either on CD-ROM subscription or on a Web site. The external links section below lists AIPs which aim to follow the EUROCONTROL eAIP Specification.
The current AIRAC cycle is 2511 (effective 30 Oct 2025).
