Rectangular Course
Fly an equal-distance ground track around a rectangular reference — the traffic pattern in miniature
~13 min FAA-S-ACS-6C
60-Second Review
Quick overviewFly a rectangular ground track a uniform distance outside a selected rectangular reference (such as a field), applying wind-correction angles on each leg and adjusting the bank and rollout on each turn so the track stays parallel and equidistant from the boundaries, while maintaining altitude and coordinated flight.

ACS Tolerances
Altitude: ±100 feetAirspeed: ±10 knotsGround track: Uniform distance from the boundary on all legs, rectangular trackCoordination: Coordinated flight throughout
Top Errors
- 1. No wind-correction angle on crosswind legs
- 2. Uniform bank at every corner
- 3. Drifting closer to or farther from the boundary
Examiner Focus
- 1. Does the applicant hold a uniform distance from the boundary on every leg?
- 2. Are wind-correction angles applied correctly on the crosswind legs?
- 3. Is bank varied appropriately at each corner for groundspeed?
