Hi,
I was flying my mavic 2 pro under decent conditions ( RTH recorded, clear sky, no tricky obstacles, 28km/h wind, less than one kilometer in distance ) and suddenly had some weird disconnections.
I tried to fly back to my home point but it seems like the drone didn't responded like it should, like if he had no juice left while the battery was ok.
I'm on iphone 12. I tried the RTH since my GPS point was perfectly recorded but I saw on my radar the drone wasn't returning. I tried to turn off/on the DJI app, disconnect / reconnect the cable ( cable is not damaged or anything) . Nothing the connection was lost. I prayed for a safe landing.
I contacted DJI Support and here is their analyze :
For your case CAS-6396161-W4L2J5, we have finished the data analysis, and the result is as follows:
1. The aircraft worked under GPS mode; It didn’t respond well to the pilot's commands due to the strong wind from the northwest;
2. Flight Time T=01:12, Relative Height H=140.7 m, Distance to Home Point D=39.4 m, the warning of strong wind appeared;
3. T=05:11, H=180.3 m, D=459.7 m, there was no pilot's input, the aircraft tilted forward for 18.5 degrees and tilted leftward for 21.6 degrees to resist the wind, but it was still blown away at the speed of 1.3 m/s, which indicated that there was strong wind affecting the aircraft;
4. T=07:51, H=175.8 m, D=653.2 m, RTH was triggered by the pilot, but the aircraft couldn't return home normally due to the strong wind; 28Km/h is too strong for a mavic 2 pro ?
5. T=08:35, H=138.2 m, D=730.2 m, the pilot pulled down the throttle stick, the flight record ended when the aircraft was descending.
According to the analysis, the incident was caused by an improper flight environment. Please do not fly the aircraft under high wind conditions.
The "strong" wind they're talking about was around 28km/h indicated by the weather app. Nothing crazy for a mavic 2 pro... I flew under way stronger wind and everything was fine. Yes I was slightly above the max height autorized but I took off down hill.
Like you can see I was flying less than one kilometer in distance and there were not any high rocks or anything to have connection problems.
I tried a rescue mission and went at the exact coordinates of the find my drone option but I found nothing. I stayed hours looking around the whole zone. The sound bip and flashlight options weren't working. Tried to rebind remote control and drone at the location also but nothing.
My drone is under warranty and I have the care refresh though I didn't found it so you know the rest of the story...
DJI proposed a 15% coupon code which I think is very light.
I read on forum some guys had also some connections issues with the last update and Iphone 12.
DJI saying it's because of the wind, but I flew under harsher conditions and never had any lost connection issue and never saw my drone struggling and not responding to my remote control.
Now I'm wondering, does anyone lost his drone in similar conditions ?
Only 15% coupon code is near outrageous : my drone is under warranty, I have the care refresh, I searched for hours around the last recorded point which wasn't the landing point but at 138m height..."the flight record ended when the aircraft was descending."
Why ? If everything was working correctly it should have recorded till the landing. The battery had still juice, no obstacles or whatsoever to loose connection still I lost connection at a distance less than one kilometer... I can provide the weather forecast of the flying place if needed you'll see the wind wasn't crazy at all...
I'd like my case to be analyzed again taking all informations into account.
