What does the term 'flying outside the visual line of sight' (BVLOS) refer to?

The term 'flying outside the visual line of sight' (BVLOS) specifically refers to operating a UAS (Unmanned Aircraft System) without direct visual reference. This means that the remote pilot does not maintain visual contact with the drone, relying instead on other means such as sensors, cameras, or pre-programmed flight paths to navigate and control the aircraft. BVLOS operations are crucial for various applications, such as long-distance inspections, search and rescue missions, and delivery services, as they expand the operational capabilities of drones beyond what is possible when pilots must maintain visual contact.

While restricted areas and autonomous landings are important topics in UAS operations, they do not define the BVLOS concept. Likewise, backup flight control systems are related to safety and redundancy but are not inherently linked to the definition of flying BVLOS. Understanding BVLOS is essential for drone operators to comply with regulations and ensure safe practices when flying without direct visual observation.
