How is yaw controlled in an aircraft?

1. By ailerons

2. By elevators

3. By rudder

4. By flaps

The correct answer is: By rudder

Yaw in an aircraft is primarily controlled by the rudder. The rudder is a vertical stabilizer located on the tail of the aircraft, and its primary function is to control the yaw motion, which refers to the side-to-side movement of the aircraft's nose. When the pilot presses on the rudder pedals, the rudder deflects, creating a force that either directs the aircraft's nose to the left or to the right. This is essential for maintaining coordinated flight, especially during turns and in crosswind conditions. The other choices relate to different control surfaces that influence the aircraft's movement in other ways. Ailerons control roll, elevators manage pitch, and flaps are used primarily to increase lift during takeoff and landing. Thus, the correct choice that specifically addresses the control of yaw is the rudder.
