Air Navigation Bureau
Aviation safety is at the core of ICAO’s fundamental Objectives. The organization is constantly striving, in close collaboration with the entire air transport community, to further improve aviation’s successful safety performance while maintaining a high level of capacity and efficiency.
The development and maintenance of Standards, Recommended Practices and Procedures applicable to international civil aviation activities are contained in 16 Annexes and 4 PANS (Procedures for Air Navigation Services). These standards are complemented by more than 50 Manuals and Circulars which provide guidance on their implementation.
