What is the primary function of a flight control system?

The primary function of a flight control system is to safely control the airplane during flight. This system comprises various components that manage the aircraft's flight path and enable pilots to maneuver the aircraft effectively. By utilizing surfaces such as ailerons, elevators, and rudders, the flight control system allows for adjustments in pitch, roll, and yaw, ensuring stable and controlled flight.

While improving fuel efficiency, measuring altitude, and monitoring engine performance are important aspects of overall aircraft operation, they do not directly pertain to the primary function of a flight control system. Fuel efficiency is influenced by various factors including aerodynamics and engine performance rather than solely the control system itself. Measuring altitude is typically accomplished by altimeters and other instruments, while engine performance is monitored by various instruments and systems throughout the aircraft. The flight control system, however, is specifically designed to enhance the safe operation and handling of the aircraft during all phases of flight.
