Which control moves the RPA left or right (yaw)?

Which control moves the RPA left or right (yaw)?

• A. Rudder
• B. Ailerons
• C. Elevators and Stabilizers
• D. Cyclic

Answer: (A)

Yaw is the rotation of the aircraft around its vertical axis, causing the nose to turn left or right. The rudder provides a side force at the tail when it deflects, creating that heading change directly, so it’s the control surface that best produces left/right yaw. Ailerons control roll by tilting the wings, not the heading. Elevators and stabilizers control pitch, tilting the nose up or down. Cyclic tilts the rotor disk to move the aircraft laterally or forward/back, but it doesn’t set the heading about the vertical axis.
