What are control tabs primarily used for?

Control tabs are primarily used to aid in the movement of control surfaces. They are small surfaces attached to a primary control surface such as ailerons, rudders, or elevators. When a pilot applies pressure to the control surface, the control tab moves in the opposite direction, creating a force that helps to deflect the primary control surface more effectively.

This assistance reduces the amount of control force required by the pilot, allowing for smoother and more responsive handling of the aircraft. The use of control tabs can enhance the overall performance and ease of flying by providing a mechanical advantage to the pilot and improving the aircraft's maneuverability.

In contrast, options that discuss fuel efficiency, engine performance, or fuselage stabilization address different aspects of aircraft design and performance, which are not directly related to the function of control tabs in aiding control surface movement.
