Definition
A trained person designated by the remote pilot in command of an unmanned aircraft to assist in seeing and avoiding other air traffic and objects in the airspace, and to help maintain the unmanned aircraft within visual line of sight during flight operations.
Plain English
A second set of eyes for a drone pilot. Their job is to watch the drone and the surrounding sky, and warn the pilot about anything they need to avoid.
Context Anchor
Used in unmanned aircraft and drone operations, especially when the pilot needs help keeping the aircraft and surrounding airspace in sight.
Derivation
Visual comes from a Latin word meaning “to see.” Observer comes from a Latin word meaning “to watch” or “to pay attention to.” Together, the term points to the person whose assigned job is to watch carefully during the flight.
Why Pilots Care
Required to satisfy visual line of sight rules and reduce the risk of airspace conflicts or loss of aircraft control.
Intuition Check
A Visual Observer is not just a casual bystander watching the flight. In this context, the person has an assigned safety role: actively watching and communicating useful information to the pilot.
Example Sentence 1
The remote pilot launched the drone for the bridge inspection while the visual observer scanned the sky for nearby aircraft.
Example Sentence 2
The visual observer relayed nearby traffic information to the remote pilot while the drone remained in controlled airspace.
