How BVLOS is different from other operations?

In BVLOS operation, the drone is flown without a pilot maintaining a visual line of sight on the aircraft at all times. Instead, the pilot operates the UAV using Remote Pilot Station (RPS) / Ground Control Station (GCS) instruments. 

But in other operations like Visual Line of Sight (VLOS), the remote pilot maintains continuous, unaided visual contact with the unmanned aircraft, and in Extended Visual Line of Sight (EVLOS), the pilot is always present on a location with one or more external observers keeping the UAV in their line of sight.

 


 






 

How does it work?

 

Drones flying Beyond the Visual Line of Sight are controlled by data provided by onboard instruments. Information is transmitted via a telemetry link that informs the operator about the position, altitude, speed, and direction of flight, and all relevant parameters of the aircraft. However, UAVs flying BVLOS can also change flight parameters and control sensors to collect data.

 

Pilots are trained differently to fly drones BVLOS. They need to have theoretical and practical training to obtain a UAVO qualification certificate with the authority to perform BVLOS flights. During training, they acquire knowledge of navigation on unmanned flights, meteorology, flight performance and planning, and flight rules. These are necessary due to the additional capabilities of unmanned systems.

 

 

Applications of BVLOS Drones 

 

Detect-and-avoid (DAA) or sense-and-avoid (SAA) capabilities are important for drones operating BVLOS, allowing them to detect nearby obstacles and air traffic and rapidly adjust their navigation accordingly. These capabilities may be provided by onboard sensors such as acoustic, LiDAR, radar, or visual cameras.

 

BVLOS flights may be integrated more efficiently into the national airspace (NAS) via the implementation of unmanned traffic management (UTM) systems, which are currently in development around the world.

 

BVLOS drones may be used for a variety of applications, including mapping, surveying, infrastructure inspection, cargo delivery, patrolling and persistent surveillance.


 

The main advantage is that you can cover a larger area without the need for observers, or the pilot moving around to keep an eye on the drone.
