Fundamentals of Surveying (FS) Practice Exam

An unmanned aerial vehicle must be operated within what distance of the remote pilot controlling the flight?

1. 1000 ft

2. 1500 ft

3. 1250 ft or within the visual line of sight of the pilot, whichever is least

4. within the visual line of sight of the pilot

The correct answer is: within the visual line of sight of the pilot

The requirement for an unmanned aerial vehicle (UAV) to be operated within the visual line of sight of the pilot is crucial for safety and control during its flight. This regulation ensures that the remote pilot can directly see and assess the UAV's operation, that is, its position, altitude, and surroundings, without the aid of any visual enhancement, such as binoculars or cameras. By maintaining visual line of sight, the pilot can respond promptly to any potential hazards or emergencies, facilitating better decision-making and lower risk of accidents. While the specified distances in the other options seem to provide guidelines, they do not fully encompass the essence of maintaining a direct view of the UAV. Safety and situational awareness are paramount, hence the correct answer emphasizes awareness and control rather than a specific distance. The regulation focuses on the ability to manage and operate the UAV effectively, which is achieved through maintaining its visual line of sight throughout the duration of the flight.
