That's where situational awareness comes into a play. As you mentions, sensors don't work at night. You have to compensate for that by flying higher than normal, or making sure you know what your MOCA (minimum obstacle clearance altitude) is.Actually, what he says is true especially about Night Flying! I’ll look up and check my Mavic Pro 2 out at night but when you fly at night, you’re basically on your own! No Sensor help and you may run into something you can’t see!
But BVLOS can be extended at night with correctly positioned lighting. The FAA doesn't allow it, but for all practical reasons, it can be used under a waiver application.
