Definition
The Airman's Information Manual is the FAA's official guide to basic flight information and air traffic control procedures in the United States. It explains how the National Airspace System works, including airspace classes, navigation aids, communication procedures, flight rules, and recommended practices for safe operations. While not regulatory in itself, it is the FAA's primary reference for how pilots are expected to operate within the system.
Plain English
The official FAA handbook that tells pilots how to fly within the U.S. air traffic system — what the rules of the road look like in practice, how to talk on the radio, what airspace means, and how to handle common situations.
Context Anchor
You will see AIM cited in FAA handbooks, flight training materials, ground school, and instructor explanations of standard flying practices.
Derivation
Airman is the traditional FAA term for a certificated pilot or crew member, regardless of gender. Information Manual signals that the document informs rather than regulates — it explains how to operate, while the actual rules live in the Federal Aviation Regulations.
Why Pilots Care
It supplies the standardized procedures pilots must follow to communicate correctly with controllers and avoid airspace violations.
Intuition Check
AIM does not mean your goal or target here. It is the short name for an FAA information manual used by pilots.
Example Sentence 1
Before her cross-country flight, she checked the AIM to review the recommended radio phraseology for entering a non-towered airport pattern.
Example Sentence 2
Section 4 of the AIM describes light-gun signals used at airports without a control tower.
