What role does the visual observer (VO) play in UAS operations?

The role of the visual observer (VO) in UAS operations is critical for ensuring safety and situational awareness during flights. A VO assists the remote pilot by maintaining visual line of sight with the drone, which is essential for compliance with regulations that require drones to be flown within the operator's line of sight. This means that while the remote pilot controls the drone from one location, the VO can provide support by observing its surroundings and identifying potential obstacles, other aircraft, or hazards in the airspace.

The VO's function complements the remote pilot's responsibilities by allowing the pilot to focus on controlling the drone while the VO actively watches for any dangers that may not be immediately visible from the pilot's perspective. This collaborative effort helps to enhance safety during operations, keeping both the UAS and the surrounding environment as secure as possible.

In this context, the other roles mentioned, such as controlling the UAS, handling communications with air traffic control, or logging flight data, do not align with the specific and focused responsibility of the visual observer. Each of these duties pertains to different aspects of UAS operation that are typically managed by the remote pilot or other personnel, demonstrating the distinct yet vital position of the VO in the flight team.
