Where are technical specifications from ICAO primarily found?

The technical specifications from the International Civil Aviation Organization (ICAO) are primarily found in annexes. These annexes are part of the Convention on International Civil Aviation, commonly known as the Chicago Convention, which outlines the standards and recommended practices for various aspects of civil aviation. Each annex focuses on different facets of aviation safety, security, and efficiency, such as airworthiness, air traffic services, and aviation meteorology, providing detailed specifications and guidelines that member states are encouraged to implement.

Annexes serve as the formal documentation of these technical standards and practices, which are developed through collective efforts by ICAO member states and experts. This structured approach helps ensure consistency and uniformity in international aviation operations, crucial for safety and interoperability across borders. This is why the annexes are recognized as the primary source of ICAO’s technical specifications.
