How do ailerons facilitate a turn during flight?

Ailerons facilitate a turn during flight primarily by creating differential lift on the wings. When the pilot wants to initiate a turn, they will bank the aircraft by moving the control yoke or stick. This action raises one aileron while lowering the other. The aileron that is raised reduces the lift on that wing, while the lowered aileron increases the lift on the other wing.

This difference in lift causes the aircraft to roll toward the wing with the increased lift, effectively initiating a banked turn. The aircraft's resultant motion is a coordination of a change in lift, which allows for a controlled and efficient turn without excessive loss of altitude.

The other options do not accurately describe the role of ailerons in aircraft maneuverability. Engine thrust is managed separately and affects speed rather than direction. Cabin pressure is irrelevant to the aircraft's lateral movements. Lastly, while the center of gravity is an important aspect of aircraft stability, it is not directly manipulated by ailerons during flight maneuvers.
