How does this get around the problem you mentioned with FAA line of sight regulations?

There’s no real way around BVLOS regs right now. The real problem is BVLOS + need to recharge. If you only solve one, you get limited value. Distributed charging without BVLOS is kind of useless. If a human still has to be there to maintain visual line of sight, it doesn't make much of a difference if the drone can recharge itself in the field. BVLOS without distributed charging also hits a value ceiling. You’re still constrained by battery swaps.

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.

Follow up question, why aerial drones? Couldn't crawler drones work and avoid FAA regulations? Though obviously would be limited in speed and where lines have been damaged, though perhaps they could be managed to go around the damage via remote control.
