What must a drone operator do if they observe other aircraft nearby?

A drone operator observing other aircraft nearby is required to stay clear and maintain separation from them to ensure safety. This is particularly important because drones and manned aircraft operate in the same airspace and can pose risks to each other if proper distance is not maintained.

Staying clear means the drone operator should actively avoid entering the flight path of any nearby aircraft, allowing them to continue their operations without interference. Maintaining separation involves keeping a safe distance to prevent collisions, ensuring that both the drone and other aircraft can operate effectively without compromising safety.

While maintaining altitude, proceeding with caution, or communicating with other aircraft may be applicable in certain situations, they do not specifically address the requirement to keep a safe distance from other aircraft, which is critical for preventing accidents. The emphasis on separation prioritizes safety in a shared airspace and is a fundamental rule in aviation practices.
