Definition
The standard flight paths flown by aircraft as they approach an airport to land (arrival) and as they climb out after takeoff (departure). At a Class C airport, these patterns are managed by air traffic control to keep arriving and departing aircraft sequenced, separated, and aligned with the runways in use.
Plain English
The flight paths aircraft follow when coming in to land and when leaving after takeoff. At busier controlled airports, ATC tells pilots how to fly them so everyone stays separated and lined up for the right runway.
Context Anchor
In Class C airspace, pilots meet this term when talking with air traffic control before entering the area, arriving to land, or departing from the airport.
Why Pilots Care
Following these patterns keeps aircraft safely separated and prevents conflicts with other traffic under ATC control.
Analogy
It is like using marked entrance and exit lanes at a busy parking lot: everyone moves more safely when they follow the expected paths.
Intuition Check
Do not read “traffic pattern” as simply “where traffic happens.” In this context, it means the expected or assigned path aircraft follow while arriving or departing.
Example Sentence 1
Approach control sequenced the Cessna into the arrival traffic pattern behind a regional jet on a four-mile final.
Example Sentence 2
After takeoff the controller cleared the aircraft via the departure traffic pattern to avoid arriving traffic overhead.
