Which of the following systems requires human intervention?

The correct selection highlights that both a Uncrewed Aircraft System (UAS) and a Remotely Piloted Aircraft System (RPAS) necessitate human involvement in their operation.

While an autonomous UAS is designed to operate independently, following pre-set parameters and using onboard sensors and artificial intelligence to navigate and perform tasks without direct human control, the other systems involve varying levels of human intervention.

Uncrewed Aircraft Systems, though capable of being automated, typically rely on human oversight for critical decision-making and handling emergencies. Similarly, Remotely Piloted Aircraft Systems are operated directly by a human pilot from a distance, meaning that human control is essential in these scenarios.

Thus, understanding the difference in the level of human involvement across different UAS types elucidates why both the Uncrewed Aircraft System and Remotely Piloted Aircraft System are categorized as requiring human intervention.
