Which two systems make up the Flight Control System?

The Flight Control System is essential for the safe and effective operation of an aircraft, as it governs the aircraft's movement and stability. The correct choice identifies the Primary Flight Control System and the Automatic Flight Control System.

The Primary Flight Control System refers to the main mechanisms that directly control the aircraft's flight surfaces, such as ailerons, elevators, and rudder. This system is crucial for manual control of the aircraft by the pilot during various phases of flight, including takeoff, cruise, and landing.

On the other hand, the Automatic Flight Control System enhances the functionality of the primary controls by providing automated control capabilities. This system helps in maintaining altitude, heading, and speed without continuous input from the pilot, allowing for more precise and stable flight, especially during long flights or challenging conditions.

Together, these systems create a comprehensive control environment that balances manual pilot input with automated enhancements, ensuring optimal performance and safety. This integration of primary and automatic controls is critical in modern aviation for enhancing both control effectiveness and reducing pilot workload.
