Hi guys,
I had lost connection with the remote on Mavic Air over the beach. I really thought that I have lost it!. Thanks to RTH it returns back. I'd like to learn from this incidents to see if I did anything wrong or what I can do to prevent furture lost connections. Here is the flight log. Appreciate the help and suggestions

Can you pls guide me how to upload flight logs onto the Phantom help web site.
It seems like one can only upload. TXT files and when I download lugs on DJI Assistant 2 it only download as a. DAT file....?
How did you get yours up onto this site...?

Hi Avian,

TXT files are saved on your mobile device. Find the directory ..root / DJI / DJI go v4 / Flightrecord.
In that dir you will find your DJIFlightRecord_year_mm_dd_[time].txt files.

Hi DoGDrone,

Had a look at your file, i cannot see any problem.
It happens to me as well the other day, a full disconnect Drone-Controller.
Happy that the RTH did function properly.

Cheers

Everything looks fine, you simply lost RC signal , when this happens you can try moving your antenna to see if you can recover signal even when Aircraft starts it’s RTH , if you regain signal you can cancel RTH .
Also area you were flying could very well be constrained by WiFi activity, best to fly in 5.8ghz mode which should not be so congested.

Hallmark007 is right. RC signal loss may be caused by obstacles between the drone and RC, the improper position of the antennas and the interference around and so on. In this case, you can try to adjust the antennas, and try to fly in open areas.

Environmental obstructions (normally tree lines) are usually the cause in my experience.

Good learning. I didn’t know that the antenna should be straight. I always put it bent to the side..

It's not too late to learn. See if it improves the flights.

Yep, always best to ensure that there is nothing between the drone and antenna on the RC and that the antenna is perpendicular to the drone throughout the entire flight.
