What are the three main types of UAS flight controls?

The correct answer identifies the three main types of UAS flight controls as manual, semi-autonomous, and fully autonomous.

Manual flight control refers to the operation of a UAS by a pilot using a remote control, allowing for direct pilot input and real-time adjustments during flight. This mode provides full control to the pilot, enabling them to navigate the aircraft based on their judgment and immediate observations.

Semi-autonomous flight control indicates a system where the UAS can perform specific tasks or maneuvers independently, while still allowing for pilot input or oversight. This often includes waypoint navigation, where the pilot can set a course and allow the aircraft to fly to predetermined points with the ability to intervene if necessary.

Fully autonomous flight control involves the UAS flying entirely on its own, guided by pre-programmed instructions and onboard sensors. In this mode, the aircraft makes decisions based on its programming without requiring human intervention, enhancing operational efficiency and enabling complex missions.

The other options do not comprehensively capture the key aspects of UAS flight control systems. For instance, manual, GPS-assisted, and fully autonomous imply a reliance on GPS for one component but do not cover the intermediate level of operator involvement present in semi-autonomous control. Similarly, remote, automated, and
