AFCS is a computer system comprised of Sensors, Processors, and which component?

• A. Gyros
• B. Actuators
• C. Displays
• D. Nav Computers

Answer: (B)

The key idea is that an automatic flight control system works as a feedback loop: sensors measure the aircraft’s state, the processors compute the needed adjustment, and actuators carry out those adjustments by moving the flight controls. Actuators are the component that actually converts the processor’s electrical commands into physical motion, changing control surfaces such as the cyclic, collective, and pedals to stabilize or steer the helicopter. Without actuators, the system could sense and decide, but nothing would move—the control commands wouldn’t be implemented. Gyros are part of the sensing elements, not a separate system component in the AFCS. Displays are for cockpit indication, not part of the control loop. Nav Computers are a different avionics subsystem focused on navigation, not the control actions of the AFCS. In the UH-60 AFCS, servo actuators execute the commands to the flight controls, making actuators the correct missing piece.
