Which autopilot component is most directly responsible for moving the aircraft's control surfaces?

• A. Servo
• B. Gyro
• C. Transmitter
• D. Antenna

Answer: (C)

Moving the control surfaces is done by the servo, the actuator in the autopilot system. The autopilot computes how far and in which direction the surfaces should move and sends a command to the servo. The servo’s motor and linkage then physically deflects the ailerons, elevator, and rudder as needed. The gyro is used to sense rotation for stabilization, but it doesn’t move surfaces. The transmitter and antenna handle communication and do not directly move the control surfaces. So, the servo is the component most directly responsible for moving them.
