What is required for a remote pilot to maintain visual line of sight (VLOS) with their RPA?

To maintain visual line of sight (VLOS) with a remotely piloted aircraft (RPA), the pilot is required to keep the aircraft within sight at all times without the use of aids. This concept is integral to ensuring safety, as VLOS allows the pilot to maintain awareness of the aircraft's position, altitude, and orientation relative to its surroundings.

When a pilot is able to see the aircraft directly, they can better avoid obstacles, respond to changing conditions, and maintain situational awareness. While using aids such as binoculars or relying on a visual observer might enhance visibility, they do not fulfill the fundamental requirement of maintaining VLOS as mandated by regulations. The use of binoculars can limit the pilot's ability to judge distances accurately and maintain spatial awareness, which is critical for safe operation. Additionally, while a visual observer can assist in monitoring the aircraft, the primary responsibility for maintaining VLOS lies with the pilot, who must ensure they can see the aircraft without aids.

In summary, the ability to keep the RPA in sight without any aids ensures that the pilot remains in control and can safely operate the aircraft, thereby adhering to the regulations governing the use of RPAs.
