AIP
Aeronautical Information Publication — the official state reference for airspace, aerodromes, routes and procedures.
The AIP (Aeronautical Information Publication) is the primary reference document of every ICAO state. It has three parts — GEN (general), ENR (en-route and airspace) and AD (aerodromes). The Czech AIP is issued by ANS CR and is available free of charge on aim.rlp.cz. Changes are published on the AIRAC cycle.
