In order to raise the right wing of an aircraft, which part of the aileron system must move down?

To raise the right wing of an aircraft, the right aileron must move down. This action causes the left wing to produce more lift compared to the right wing, resulting in the desired roll movement. When the right aileron moves down, it increases the angle of attack on the left wing, enhancing lift on that wing, while simultaneously decreasing the lift on the right wing.

Understanding the mechanics of ailerons is crucial. Ailerons are located on the trailing edges of the wings, and they work in opposition to each other. When one aileron moves down, the opposite aileron moves up. Thus, lowering the right aileron effectively raises the left wing, causing the aircraft to roll to the right.

While the other components listed, such as the left aileron and trim tabs, serve functional roles in flight control, they do not directly contribute to the immediate action of raising the right wing as explicitly as the right aileron does when it moves down.
