So the solution here is a deep understanding of FAA BVLOS waiver processes + a drone/pad network that is actually scalable.
That said, this is another benefit of working with utilities. When you’re inspecting power line corridors, you’re often operating in what the FAA calls “shielded area.” In practice, that just means you’re flying close to infrastructure that other aircraft tend to avoid anyway. That makes deconfliction much simpler, which in turn makes BVLOS waivers more attainable under Part 107.
The bigger shift is Part 108, which is expected to be finalized relatively soon, and should lower the barrier to BVLOS at scale.
Delivery drones are leaving line of sight and yet they are operating. The Walmart near me started delivery late last year, and they are buzzing my area many times a day. I'd hope with enough testing these guys can work with the FAA to get certified to remove this limit.
It's also mechanically complex and there's many line & pole types that make it challenging to build for.
When we let go of distribution line charging, we considered this idea. Off some rough calcs we thought there would be lines that we'd get 'stuck' on so that was hard to overcome...
