Definition
A trained crew member who assists the remote pilot of an unmanned aircraft by maintaining direct visual contact with the aircraft and its surrounding airspace, and by communicating any hazards or relevant information to the remote pilot in command.
Plain English
A second person on a drone crew whose job is to keep their eyes on the drone and the sky around it, and tell the pilot about anything they need to know.
Context Anchor
Used in unmanned aircraft operations, especially when a remote pilot uses another person to help maintain awareness of the aircraft and the area around it.
Derivation
“Visual” comes from a Latin word meaning “to see.” “Observer” comes from a Latin word meaning “to watch” or “to keep watch.” Together, the words point to the main job: watching the aircraft so the pilot has better awareness.
Why Pilots Care
A visual observer extends the remote pilot’s ability to maintain required visual line of sight and supports safe collision avoidance.
Intuition Check
A visual observer is not just someone nearby who happens to see the aircraft. In this aviation use, the person is deliberately assigned to watch the aircraft and communicate useful information to the pilot.
Example Sentence 1
Before launching the drone near the construction site, the remote pilot briefed the visual observer on the planned flight path and hazards to watch for.
Example Sentence 2
Before takeoff the visual observer confirmed they had a clear view of the entire flight area and would call out any traffic.
