What is the device used by an autopilot to actuate a control surface?

• A. Throttle
• B. Switch
• C. Servos
• D. Actuator

Answer: (C)

An autopilot system relies on specific devices to control various functions within the aircraft, including the actuation of control surfaces such as ailerons, elevators, and rudders. Servos play a critical role in this process. They are electromechanical devices that convert electrical signals into mechanical movement. When the autopilot system determines the need to adjust a control surface to maintain or change the aircraft’s flight path, it sends a command to the servo. The servo then moves in response to these commands, physically repositioning the control surface as needed. This allows for precise control, making it crucial to the effective functioning of the autopilot. Understanding other components mentioned, while relevant in aircraft operation, they do not directly actuate control surfaces in the same manner. Throttles manage engine power, switches serve to control various systems but are not involved in actuation directly, and actuators can refer broadly to devices that create movement but do not specifically indicate the servo’s role in autopilot systems.
