[QUOTE="LKLM-Media, post: 93293, member: 17874"] I believe you are sort of on track - IMHO it isn't that it "Can't see the ground" - in this situation I think the IR and bottom mount camera act in reverse and feel there IS a solid object already at close proximity - I have noted this in my post that sometimes when you get too close to ground even in normal flying it will initiate an autoland procedure. It's really just the CPU programming being a bit too smart for it's own good. But could also be a safety aspect for all we know - would have to ask DJI... But for reference - try this: [MEDIA=youtube]QweMuuqgVEc[/MEDIA] He notes that when in regular GPS mode as soon as he got close to the ground, i.e. maybe on uneven surface where attitude was nominal but the ground rose up - the Drone "stops" - again you can see how this would be a safety aspect if for instance you were shooting something facing backwards - on Follow me, or manually, but if the ground rises without your knowing then the drone will land instead of Crashing... In my Fog session I didn't notice the symbol change next to the Height - in fact it still showed H and 0.5m - But I plan to do a few sessions this week where I will hopefully be able to test various aspects. ***APPARENTLY*** - If you use LITCHI - there is an option to turn off the Bottom Sensors.
