Aeronautical Information Publication (AIP)
Definition
The AIP is a comprehensive, legally binding reference document published by a country's national aviation authority. It contains all essential information relevant to air navigation, including airport data, airspace structure, navigation aids, communication procedures, and regulatory requirements.
Each country maintains its own AIP, following a standardized structure defined by the International Civil Aviation Organization (ICAO).
Purpose
- Pre-flight planning
- Legal and procedural compliance
- Operational awareness for pilots, air traffic controllers, and dispatchers
Structure (ICAO Format)
GEN (General)
- Contact details of aviation authorities
- Licensing requirements
- Rules of the air
- Meteorological and SAR services
- Charges for airport and air navigation services
ENR (Enroute)
- Airspace classification and structure
- Navigation aids and routes
- ATC procedures
- Traffic separation services
- Flight planning requirements
AD (Aerodromes)
- Detailed airport data for each registered aerodrome
- Runway specifications, lighting, taxiways, parking stands
- Radio frequencies
- Arrival, departure, and approach procedures
- Charts and obstacle data
Format & Access
Most countries publish their AIP in digital format and make it accessible online, either freely or through subscription services. For example:
- Germany: AIP provided by DFS Deutsche Flugsicherung
- Austria: AIP available through Austro Control
- France: Via SIA (Service de l’Information Aéronautique)
Updates
AIPs are regularly updated through Amendments (AIRAC cycles) in accordance with ICAO schedules. These changes are announced in advance and ensure that all aeronautical data remains current and accurate.
Related Terms
- NOTAM – Notices to Airmen for temporary changes not yet in the AIP
- AIC – Aeronautical Information Circulars for general or administrative info
- SUP – Supplements for major temporary changes (e.g., airshows, runway closures)
In Practice
Before flight, pilots use the AIP to check:
- Destination and alternate airport data
- Communication frequencies
- Available navigation aids and approach procedures
- Airspace structure and restrictions en route
- Local regulations and operational rules
Using outdated or incorrect AIP data can lead to regulatory violations or safety issues.
