Our BVLOS Definition infographic shows the interconnection between VLOS (visual-line-of-sight), EVLOS (extended-visual-line-of-sight), and BVLOS (beyond-visual-line-of-sight) in terms of the radius around a drone operator. Despite the fact that a “range of sight” might vary between individuals, this BVLOS definition shows 1) how another observer could extend the visual line of sight of the operator until neither can see the drone, 2) how an object such as a tree might block the view of the operator, thereby causing a BVLOS situation.
The right side of the BVLOS definition show that even when an operator’s visual-line of sight reaches its limit (darker blue cylinder), a second observer can turn this into a EVLOS situation by extending the line of sight. Though this has its benefits to carry our certain drone operations, it also carries several limitations, especially since the additional observer does not operate the drone.
On the left side of the image we see how a tree can block the view of a drone operator even if it is not so far from the operator. This also fits into a BVLOS definition since it means that a drone pilot must operate the drone without being able to see it or any other obstacles that the drone’s camera or sensors might not detect.
If you’re looking for more information on the effects of BVLOS capability on the potential for drone operations, read our blog post. Here is an excerpt from the blog:
“By allowing companies to leverage the use of BVLOS at a higher level of automation, drone technology will finally unleash its disruptive potential. Processes will be quicker and more efficient; data will be acquired at higher quality while keeping workers out of harm’s way and all of this will carry a much smaller ecological footprint.”
