Final answer:
In straight flight, small deviations from wings level can be more easily corrected by using aileron control.
Step-by-step explanation:
In straight flight, small deviations from wings level can be more easily corrected by using aileron control. Ailerons are control surfaces on the wings of an aircraft that control its rolling motion. By moving the ailerons up or down on one wing while keeping the other wing level, the aircraft can be leveled and any small deviations corrected.
