If an sUAS flies under another aircraft during a maneuver, what must the remote pilot ensure?

Selecting the option that the air vehicle is well clear of the other aircraft is crucial for ensuring safety in shared airspace. When an sUAS operates in proximity to manned aircraft, the remote pilot is responsible for avoiding any potential collisions. This responsibility involves maintaining a safe distance and ensuring that the sUAS does not interfere with the flight operations of the other aircraft.

Being well clear entails understanding the operational height, speed, and path of both the sUAS and the manned aircraft. This ensures that the remote pilot can anticipate and manage any risks associated with close encounters, which is vital for maintaining safety standards and adhering to the regulations that govern airspace.

While the other options contain important elements related to flying an sUAS, ensuring that the sUAS is well clear of another aircraft directly addresses the most critical concern of safety in the operation, thereby making it the correct choice.
