Which of the following is NOT considered a flight control in fixed-wing aircraft?

In fixed-wing aircraft, the primary flight controls include ailerons, elevators, and flaps, all of which play crucial roles in the management of the aircraft's movement and stability in flight. Ailerons control the roll of the aircraft, elevators manage pitch, and flaps enhance lift during takeoff and landing by changing the wing's shape.

Struts, on the other hand, are structural components that provide support and stability to the aircraft's wings and fuselage. They are essential for the overall integrity of the aircraft but do not influence the aircraft's flight path or control inputs. Thus, they are not classified as flight controls but rather as part of the aircraft's structural framework. This distinction is key to understanding the various systems that contribute to the operation of fixed-wing aircraft.
