Definition
A flight path in the traffic pattern parallel to the landing runway and flown in the same direction as the intended landing.
Plain English
A straight section of the airport traffic pattern flown alongside the runway, going the same way you would land.
Context Anchor
Used when describing or flying the standard traffic pattern around a runway, especially during arrivals, go-arounds, and practice pattern work.
Derivation
Upwind' simply means 'into the wind.' Since aircraft normally take off and land into the wind, the leg flown in that direction along the runway is called the upwind leg.
Why Pilots Care
Flying the upwind leg at the correct altitude and distance keeps traffic sequenced safely and prevents conflicts with aircraft on crosswind or downwind legs.
Intuition Check
Do not read “upwind leg” as any flight into the wind. In airport pattern language, it means a specific straight segment parallel to the runway and flown in the landing direction.
Example Sentence 1
After the go-around, the pilot climbed straight ahead on the upwind leg before turning crosswind.
Example Sentence 2
The pilot announced position on the upwind leg while maintaining spacing behind the aircraft that had just departed.
