What is required for an RPA operation regarding visibility?

For Remote Pilot Aircraft (RPA) operations, maintaining a visual line-of-sight is a crucial requirement. This means that the remote pilot must be able to see the RPA with their own eyes, ensuring they can effectively monitor its position, altitude, attitude, and the surrounding environment. This visibility allows the pilot to make real-time decisions to avoid obstacles and other aircraft, as well as to respond swiftly in case of any emergencies.

This requirement stems from safety regulations that dictate the need for situational awareness during RPA flights. Keeping the aircraft within visual line-of-sight ensures that the pilot has control over the RPA and can react to any potential hazards in its vicinity. Relying solely on instruments or first-person view (FPV) equipment does not provide the same level of safety, as it may limit the pilot's awareness of the aircraft's surroundings.

In this context, other options reflect misunderstandings of the visibility requirements. While poor visibility, the use of visual aids, or the idea that only the pilot needs to see the RPA might have some relevance in different scenarios, they do not align with the fundamental principle of maintaining direct visual contact during RPA operations, which is essential for safety and effective management of the flight.
