Are wing flaps considered a primary flight control?

Wing flaps are not considered primary flight controls. Primary flight controls are the main controls used to maneuver an aircraft, which typically include ailerons, elevators, and rudders. These controls directly affect the aircraft's roll, pitch, and yaw movements.

Flaps, on the other hand, are secondary flight controls that are used to increase lift and drag during specific phases of flight, such as takeoff and landing. They assist in allowing the aircraft to fly safely at slower speeds, but they do not directly control the aircraft's basic flight dynamics like the primary controls do.

This distinction is important because understanding the roles of different flight controls helps pilots effectively manage aircraft handling and performance throughout various flight stages.
