Which pairing is described as 'Change Yaw'?

• A. Vertical Stabilizer
• B. Rudder
• C. Elevator
• D. Horizontal Stabilizer

Answer: (B)

The surface that changes yaw is the rudder. Yaw is the rotation of the aircraft around its vertical axis (nose turning left or right). Deflecting the rudder with the pedals pushes air to create a yawing moment, steering the aircraft left or right and changing its heading. The rudder is located on the trailing edge of the vertical stabilizer, which provides directional stability, but only the rudder moves to produce that yaw change. The elevator on the horizontal stabilizer controls pitch (up and down), while the horizontal stabilizer itself mainly contributes to longitudinal stability. The vertical stabilizer by itself provides directional stability but does not actively change yaw without the rudder. So the action that directly changes yaw is the rudder.
