Lost my Mavic Air and cant find it! Please help

[Reboh613]

Hi,

I was flying my drone all was good accept it was a little choppy at close proximity when i was flying it at the park. It was when I was hovering a tennis court and taking pictures that It suddenly lost transmission. I waited a little bit but was freaking out because it was only 400 feet away and very unusual that it would go completely dark. Anyways, I freaked out and shut off my controller thinking I would restart it but that did nothing.

My flight recorder shows that the last place was hovering the tennis court. I think it was set to go 20m down and then go home. Why can’t I see exactly where it crashed? Because it’s impossible that it crashed where it last was seen because nothing was under it and it was up 350 feet.

Below are my flight records if anyone can help maybe pinpoint where it is. Thank you!








Then apparently it turned back on a few hours later and says its 2.6 feet off the ground . Does this mean it is actually 2.6 feet off the ground or can it be 65 feet up on a tree but it is calculating the next branch below it which is 2.6 feet off the ground?

Someone (@sar104) will ask you to post your logs for analysis, but I can see that a new home point was created at spot E. Did you look there? If it landed there then someone probably picked it up by now. Did you have your phone number on it?

Welcome to the forum, just sad it is under such unfortunate circumstances.
Hopefully you can find it, and in one piece.

Can you see if you can retrieve the mobile device DAT file ending FLY096.DAT? That should contain location data.

when I open it on VLC it’s empty. Says under duration 00:00... what does that mean? New to this..

I was near there so I know it didn’t land there.

Amongst other things it means that it's not a video file. You need either to post it here, or examine it yourself:

You were very impatient and took off and flew some distance without GPS or a home point.
The drone was not able to record a home point until 2:54 so it will be some distance from where you launched.
The homepoint recorded was at 40.07241 -75.12409 and after losing signal that's where the drone would have attempted to return to.
This is shown by the yellow arrow.

The recorded flight track suggests another home point but I can't tell where it got that from
It's shown by the black arrow and it is not the home point which is shown in the flight data.

Your drone will never descend to RTH.
It will have attempted to fly to a point above the home point and then descend.

Now this gets more interesting... there were no trees in the area that are 350 feet high...

Okay - so it didn't reconnect later - the log file with the 2:20 pm timestamp is actually from just before the last flight, and the timestamp is wrong. So the DAT file ends at the same point as the flight log, with no indications or any problem.

There really are only a few possibilities here.

1. The aircraft shut down due to processor crash or power failure;
2. The aircraft disconnected from the RC (unlikely) in which case it would have entered RTH almost immediately;
3. The app disconnected and the aircraft eventually went to RTH, which would have been 150 seconds after the disconnect.

There was very little wind - around 2 m/s out of the north, and so it would have crashed onto the tennis court as shown by the power-off descent track shown below in green.

The home point was as indicated by @Meta4 above, and if (2) or (3) occurred then it would have returned there - the red pin below.

Thank you for your response. It’s hard to believe It landed on the tennis court as I was at the scene 5 min after loosing connection. No where to be found with no one around...
