Final answer:
Controllers that try to assist pilots in avoiding requested areas are unmanned aerial vehicles (UAVs) controlled by operators on the ground. By steering the drone away from these requested areas, they can ensure the safety of both the pilot and the surrounding civilian populations.
Step-by-step explanation:
The question is referring to unmanned aerial vehicles (UAVs) or drones that are used for surveillance and military purposes. These drones are controlled remotely by operators on the ground who can assist pilots in avoiding requested areas. By using advanced navigation systems and real-time data, the controllers of these drones can guide the pilots and provide situational awareness, helping them avoid restricted or dangerous airspace.
For example, if a pilot requests to fly through an area that is restricted or poses a threat, the controller can advise them to reroute to a safer path. Additionally, the controllers can assist in avoiding areas where a military operation or enemy activity might be taking place. By steering the drone away from these requested areas, they can ensure the safety of both the pilot and the surrounding civilian populations.
