Definition
Aeronautical Information Services (AIS) is the FAA office responsible for collecting, maintaining, and publishing the official aeronautical information that pilots use for flight planning and navigation. This includes data on airports, airways, navigation aids, airspace, instrument procedures, and obstacles. AIS produces and distributes the charts and publications that carry this information, such as the Chart Supplement, instrument approach procedure charts, en route charts, and the Notices to Air Missions (NOTAM) system feeds.
Plain English
AIS is the part of the FAA that gathers all the official information pilots need about airports, airspace, and routes, and turns it into the charts and publications pilots actually use.
Context Anchor
Seen in FAA publications and in discussions of official aviation information sources, including charts, procedures, airport data, and flight notices.
Derivation
‘Aeronautical’ comes from Greek roots meaning ‘relating to flight in the air.’ ‘Information services’ is plain English for ‘a service that supplies information.’ Together it names the FAA function that supplies flight information to pilots.
Why Pilots Care
Keeps pilots aware of airport conditions, restrictions, and hazards so they can plan and fly safely.
Intuition Check
AIS is not a person giving casual advice. It means the organized official system that provides the aviation information pilots and operators use.
Example Sentence 1
The chart legend listed AIS as the publishing authority, confirming the data was from the official FAA source.
Example Sentence 2
AIS updates are used to keep navigation charts and airport directories current.
