It does make sense in a way. If you lose GPS, the only thing that will keep it steady is the VPS. ...

I could buy that, except when I consider the situation where it would happen, such as with tree cover, going down to explore a valley and other such scenarios, it would mean even greater loss of control and signal.



"Hey, I've lost GPS signal, so I'm going to descend into this valley, in among the trees and stuff, maybe you can find me later?", doesn't strike me as at all useful?



Just to be clear, we're talking GPS signal, not control signal, BUT IT OVER-RIDES YOUR CONTROL SIGNAL AND DESCENDS, that's the bit I have a real problem with.



An urgent error message, about having lost GPS positioning, asking "Do you wish to descend for visual positioning?", fine. I can decide if that's appropriate or not.



But over-riding my control and descending anyway, out of sight and losing control and video signal, where it could be 200 or 300 meters away? A kilometer away?



Then just running out of battery and landing wherever it happens to be at the time, in the trees, in a river, on someone's roof? That's nutz.



The video is in Chinese, so I'm not sure how the pilot managed to get it to come back up again? But my impression with a quick view earlier was that the Mavic was ignoring his control stick commands and descending against his will.



Edit:

The Mavic in the video is engineering simple with bata firmware.

Mass production won't have this issue.Please don't worry about it.

Ah, OK, that's what I wanted to hear
