What is the basic function of a UAS's flight controller?

The basic function of a UAS's flight controller is to manage flight dynamics and stabilize the aircraft. The flight controller acts as the brain of the unmanned aerial system, processing inputs from sensors and making real-time adjustments to control surfaces and propulsion systems. This ensures that the aircraft operates smoothly and maintains stability during flight, which is crucial for both safety and performance. The flight controller continuously evaluates the aircraft's orientation, speed, and position, adjusting the throttle and control surfaces as needed to compensate for wind and other external factors.

While communication with satellites is important for GPS-based navigation, the primary role of the flight controller is focused on stabilizing and controlling the aircraft in the air. Camera settings and autonomous navigation are secondary functions that may be managed by other systems or software integrated with the flight controller, but the core responsibility remains ensuring stable and controlled flight dynamics.
