An Autonomous Uncrewed Aircraft System has which of the following features?

An Autonomous Uncrewed Aircraft System (UAS) is characterized primarily by its ability to perform functions without the need for continuous human intervention. This feature allows the system to operate independently after being programmed with a specific set of tasks or parameters. While it may have programmed instructions or algorithms to follow, the definition of "autonomous" emphasizes that it can carry out missions or functions without real-time human control.

In contrast, the characterization of using a human pilot for missions contradicts the principle of autonomy. A human pilot's direct involvement suggests a manual or semi-automated system, whereas the essence of an Autonomous UAS is its self-sufficiency. Similarly, limitations to visual line of sight operations do not apply, as autonomy can allow for operations beyond such constraints, depending on the design and regulations governing the specific UAS.
