FAA Assembly & Rigging Practice Test

When the control stick of a properly rigged aircraft is moved rearward and to the left, the aircraft is entering a left turn. In this scenario, the right aileron will respond by moving down. This is due to the operation of the aileron system, which is designed to create differential lift between the wings for rolling the aircraft.

When the left side of the control stick is pulled back, the left aileron moves down, which increases lift on the left wing and causes that wing to rise. Simultaneously, the right aileron moves up, which decreases lift on the right wing, causing that wing to drop. This difference in lift causes the aircraft to roll to the left.

Therefore, the movement of the control stick to the left results in the right aileron moving down, enhancing the lift differential necessary for turning left. This dynamic interaction of the ailerons is crucial for effective control and maneuverability of the aircraft during flight.
