What role does the UAS methodology of "visual observers" play in an operation?

The methodology of using visual observers in Unmanned Aircraft Systems (UAS) operations is crucial for maintaining safety and situational awareness. The primary role of visual observers is to assist the remote pilot by ensuring that the drone remains in visual line of sight. This is a requirement under FAA regulations, which state that the remote pilot must always keep the drone within visual awareness to manage potential risks and avoid obstacles or other aircraft.

Visual observers serve as additional eyes in the field, focusing on the drone's position and how it interacts with its environment while the remote pilot may need to focus on other aspects of the operation, such as takeoff, landing, or controlling the drone. By having a dedicated visual observer, the likelihood of maintaining a safe operational environment increases, leading to enhanced overall safety in UAS operations.

This role is fundamentally different from the other options presented. For instance, maintaining communication with air traffic control is typically the responsibility of the remote pilot, who must remain accountable for the operation of the drone. Operating the UAS without the remote pilot contradicts the regulations, as the pilot must always be in control. Finally, while GPS technology is essential for navigation, using visual observers specifically enhances safety through situational awareness, rather than through navigation systems.
