What is the primary purpose of the Aeronautical Information Manual (AIM)?

The primary purpose of the Aeronautical Information Manual (AIM) is to serve as the official guide to basic flight information and Air Traffic Control (ATC) procedures. The AIM provides vital information necessary for pilots and those involved in aviation operations, including details on navigation, airspace classifications, and safety procedures. It is designed to support safe and efficient flight operations by offering comprehensive information that pilots can reference during their flight planning and operations.

By focusing on essential flight-related knowledge and ATC interaction, the AIM acts as a central resource for standardized procedures and practices, ensuring that all users have access to uniform information about operating in the National Airspace System. This purpose remains distinct from merely expanding on regulatory guidelines or providing specific training techniques, as the AIM is not a regulatory document in itself but rather an informative guide that complements the regulations set forth in the Federal Aviation Regulations (FARs).
