Definition
An official FAA publication that provides pilots with the basic flight information and air traffic control procedures used in the U.S. National Airspace System. It explains how the system works in practice — including airspace, navigation aids, communications, flight procedures, wake turbulence, medical factors, and standard operating practices — and is updated periodically to reflect current rules and procedures.
Plain English
A handbook from the FAA that tells pilots how to operate in U.S. airspace — what the rules look like in real flying, how to talk to controllers, and how to use the system safely.
Context Anchor
Pilots encounter the AIM during flight training, preflight planning, and when checking the standard way to handle airport, radio, or air traffic situations.
Derivation
From Latin 'aeronauticus,' meaning relating to flight or air navigation. 'Manual' comes from Latin 'manualis' (handbook). So 'Aeronautical Information Manual' literally means a handbook of flight information — which is exactly what it is.
Why Pilots Care
Pilots rely on it to use correct procedures, avoid airspace violations, and operate safely within the U.S. system.
Intuition Check
AIM does not mean aiming or pointing the airplane here. In aviation, AIM is the short name for the FAA’s Aeronautical Information Manual.
Example Sentence 1
