Definition
The specified path to be flown by aircraft operating in the vicinity of an aerodrome. It defines the route used for arriving, departing, and circling aircraft to maintain orderly and predictable traffic flow around the airport.
Plain English
A set flight path that aircraft follow around an airport when taking off, landing, or staying in the area, so everyone flies in a predictable pattern.
Context Anchor
Seen in ICAO-based procedures, international flight training, and discussions of aircraft movement near an airport or landing area.
Derivation
Aerodrome' comes from Greek aēr (air) + dromos (running course) — literally an 'air course,' meaning an airfield. 'Circuit' comes from Latin circuitus, meaning 'a going around.' Together: the flight path that goes around an airfield.
Why Pilots Care
Standardizes arrivals and departures to maintain safe separation and reduce collision risk near the airport.
Intuition Check
Circuit does not mean an electrical circuit here. It means a flight path that goes around the aerodrome in an organized pattern.
Example Sentence 1
The instructor cleared the student to join the aerodrome traffic circuit on the downwind leg.
Example Sentence 2
All aircraft were instructed to remain in the aerodrome traffic circuit until cleared for final approach.
