Which leg(s) of a standard traffic pattern is flown perpendicular to the downwind leg?

Answer: B — Base and crosswind legs

The base and crosswind legs of a standard traffic pattern are positioned perpendicular to the downwind leg, making this the correct answer. In a standard traffic pattern, the sequence begins with the takeoff on the upwind leg, followed by the crosswind leg, which is flown at a right angle to the downwind leg. After the crosswind leg, the aircraft turns onto the downwind leg, maintaining a parallel course to the runway. When it’s time to prepare for landing, the aircraft makes another turn, this time onto the base leg, which again is perpendicular to the downwind leg. Finally, a turn onto the final approach leg aligns the aircraft for landing. Understanding the layout of the traffic pattern is crucial for maintaining safe separation between aircraft. By flying the base and crosswind legs perpendicular to the downwind leg, pilots ensure a clear and organized flight path around the airport, promoting predictable movements that are essential for efficient air traffic management.
