How can a pilot change the camber of the wings during flight?

The camber of the wings can be changed during flight primarily by using flaps or ailerons. Flaps are movable surfaces located on the trailing edge of the wings that, when extended, increase the curvature or camber of the wing. This increase in camber enhances lift at lower speeds, which is particularly useful during takeoff and landing. By deploying flaps, pilots can effectively modify the wing's aerodynamic characteristics to optimize performance based on the flight phase.

Ailerons, while primarily used for roll control and to manage the aircraft's lateral balance, can also have a minor impact on camber due to their location on the wing. However, their primary function is not to change the wing shape but rather to influence the aircraft's aerodynamic roll behavior.

In contrast, adjusting the stabilizers and altering the wing load do not directly modify the wing camber. The stabilizers adjust pitch control, and wing loading relates to the weight distribution over the wing but does not alter its shape during flight. Therefore, using flaps or ailerons is the correct answer, as these controls allow a pilot to actively change the camber of the wings to achieve the desired aerodynamic effect.
