Hi there,

My Mavic Pro landed automatically in the ocean today.

It triggered a RTH and decended onto the ocean.

Need help. Can I attach my flight log?

Regards,
Jing

It will help if you can post your .txt file to dropbox or similar and post a link.

Can you post the link to the Phantomhelp report please?

Hi,

My guess ; with no satellites your drone thinks that it is close to home.....So pressing RTH will cause it to autoland.
In the second screen shot 14 sats, so HP is probably set, flying close to HP will start a autolanding too.


But it is all in the flightlog ; when you activated RTH irt Distance to HP...(post the PH link to you flightlog on here if you like)

cheers
JJB

If you can post a link to the Phantomhelp report instead of a pic of part of it, we'd be able to see what happened instead of guessing without really knowing.

My impression was that HE did not activate RTH - that it did it itself.

Hello there, I've uploaded the logs & there's access to my google drive.

Hello,

The time is beyond the warranty period since it's 2017 model. But I don't think that if the drone flies itself into the ocean, then DJI should be helpful enough to replace it.

By the way, the customer support are asking me for $35 to look at the flight logs, which I don't think is very helpful.

Here are the links to my flight logs.

Ok I have two files, a txt file & the DAT file, I hope these can help.

Your flight data looks like this:  https://www.phantomhelp.com/logviewer/WHHKUZ3O4L8MGWQ2CPYO/

You started flying full speed at 0:02.9.
But you had no GPS and so no home point was recorded where you launched.
Your Mavic started getting GPS reception at 0:30.9 and recorded a homepoint where it was at 0:34.1.
AT 0:52.3 there was a warning message advising that you were in a no-fly zone and autolanding commenced.

If you had waited for GPS before launching, the drone would have identified that it was in a NFZ and would have prevented launching.

Mmm ... patience is usually a good thing when flying drones.

You was just within the DJI Fly safe authorization zone for Ngurah Rai International Airport. It's a blue zone so if you had waited for your HP to be updated before taking off you had been prompted for it & also actually been able to unlock it then & there. Also saw in the log that you didn't do anything when the auto landing started ... if you had steered towards the beach immediately you possibly had time to get it to dry land before reaching ground/sea level.

When looking into the DAT log it also looks like you actually got a 20sec countdown before the auto landing started ...



Next time flying a drone, wait for the HP to be recorded in the correct spot before take off & check the map view for possible authorization zones ... they are visible directly on the map.

Hi Slup, great reply.

My flight zones have been recently updated, and there seem to be four colour coded areas: grey, red, blue and orange. I understand that red and blue areas are hardware locked no-fly areas by default, any idea what the altitude limit is for the grey, and what restrictions, if any, that apply to orange zones?

Cheers,

DB

Not higher than indicated in the gray areas, depending on national laws. Otherwise like orange. I cannot answer whether something will happen above the height indicated in gray.

Sorry . My condolences
