Aeronautical Information Manual

In United States and Canadian aviation, the Aeronautical Information Manual (AIM) [1] is the federal regulatory body's official guide to basic flight information and ATC procedures.

This manual contains the fundamentals required in order to fly legally in the country of origin. It also contains items of interest to pilots concerning health and medical facts, factors affecting flight safety, a pilot/controller glossary of terms used in the ATC System, and information on safety, accident, and hazard reporting. Although the AIM is not regulatory in nature, parts of it re-state and amplify federal regulations.
