Which term describes a remote pilot's responsibility for the operation of their aircraft?

The term that describes a remote pilot's responsibility for the operation of their aircraft is "Pilot in command." This designation indicates that the remote pilot has the ultimate authority and responsibility for the safety of the flight, including compliance with regulations, managing the aircraft's performance, and making critical decisions throughout the flight. The pilot in command is accountable for ensuring that all operational procedures are followed properly and that the aircraft is operated safely during its mission.

Operational authority, while related, does not encompass the full scope of responsibility that comes with being the pilot in command. Flight safety is an important consideration, but it is a broad concept that encompasses multiple aspects of aviation without specifically identifying the pilot's direct accountability. Aeronautical decision-making refers to the process pilots use to make informed choices during operations but does not explicitly capture the overarching role and responsibility of commanding the aircraft. Thus, the most accurate term reflecting the remote pilot's responsibility is "Pilot in command."
