What is the main purpose of a servo in an autopilot system?

• A. Enhance navigation accuracy
• B. Move the control surface as commanded
• C. Communicate with the flight crew
• D. Monitor engine performance

Answer: (B)

The primary role of a servo in an autopilot system is to move the control surfaces as commanded. Servos are electromechanical devices that convert electrical signals into mechanical motion. In the context of an autopilot, they receive signals based on the autopilot's commands, which are determined by the flight management system or the pilot's input, and then act on the control surfaces of the aircraft, such as the ailerons, elevators, or rudders, to adjust the aircraft's flight path accordingly. By accurately positioning these control surfaces, servos enable the autopilot to maintain stable flight, execute turns, climbs, descents, and other maneuvers without direct pilot intervention. This automation provides a crucial function in enhancing the efficiency and safety of flight operations, allowing the pilot to focus on other aspects of the flight. While enhancing navigation accuracy, communicating with the flight crew, and monitoring engine performance are important aspects of an aircraft's overall systems, they do not encapsulate the direct physical function of a servo in moving control surfaces. Thus, the servo's focus is distinctly on the execution of control commands as directed by the autopilot system.
