International Civil Aviation Organization (ICAO)

About ICAO

The International Civil Aviation Organization (ICAO) publishes regulations for aviation safety, security, efficiency and regularity, as well as for aviation environmental protection. The organization also regulates operating practices and procedures covering the technical field of aviation, leveraging its unifying influence in developing a code of international air law for over 180 countries.

ICAO adopts international regulations and recommended practices (SARPs), and incorporates these into the annexes to the Convention on International Civil Aviation. The SARPs cover air navigation, prevention of unlawful interference and facilitation of border crossing procedures for international civil aviation.

Standards and recommended practices (SARPs)
Procedures for air navigation services (PANS)
