Definition
A restricted portion of an airport where aircraft movement, servicing, and ground handling take place. It includes runways, taxiways, ramps, and the surrounding areas used to support aircraft operations, and access is controlled to prevent unauthorized entry of people or vehicles.
Plain English
The part of the airport where aircraft are flying, taxiing, parking, or being worked on. Only authorized people and vehicles are allowed in.
Context Anchor
You may see AOA in airport security rules, airport operations notices, airport badges, NOTAM contractions, or procedures that describe where pilots, vehicles, and ground personnel may operate.
Why Pilots Care
Knowing AOA boundaries prevents runway incursions and keeps operations safe and legal.
Grounding Statement
Picture the secured side of the airport fence where aircraft are parked, moving, taking off, or landing; that is the kind of area meant by AOA here.
Intuition Check
Do not read AOA here as angle of attack. In this NOTAM and airport-operations context, AOA means air operations area: the controlled airport area where aircraft operations occur.
Example Sentence 1
The lineman swiped his badge at the gate before driving into the AOA to marshal the arriving aircraft.
Example Sentence 2
All vehicles entering the air operations area must display an airport badge.
