Aeronautical Information Manual
In United States and Canadian aviation, the Aeronautical Information Manual (AIM) (formerly the Airman's Information Manual) is the respective nation's official guide to basic flight information and air traffic control procedures. These manuals contains the fundamentals required in order to fly legally in the country of origin. They also contain 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 AIMs are not regulatory in nature, parts of them re-state and amplify federal regulations. United States
