Could could anyone confirm the meaning of the top altitude on the flight log please?

I've had eight flights in and around home, none of whuch are anything like what I assume is a reference to sea level.
From memory the highest point in Yorkshire is 750m, nothing like that shown on my log.

Thanks in advance.

EDIT: Just realised what you mean. Not sure on that, mine says Max Takeoff Altitude there

I synced my flight log and my Max altitude changed from the correct value to 1658.6m. I am also in the UK.

Thanks, but I've synced it numerous times starting with the evening of my flights.

Just synced mine for the first time now and the correct value of 605m (above sea level) changed to 6056m after sync. Think they need to play with decimals a bit, hah

I definitely didn't take my Mavic to 165m altitude either.

Mine has Max Takeoff Altitude.  Is there anywhere to compare every ones different levels?  I wonder how high some of the longtime DJI users are at.

You can clear your logs if you want and the altitude will go away.

My altitude showed over 15,000 feet (1,000 ft too high) after I flew just over 14K for the first time.  After you sync your flight logs with DJI, you can clear them and this number will be set back to zero.

Thanks for the tip Wolf - I will take a look.

Are you guys also running the Android App?

But won't that then mean the flight logs with DJI are incorrect?

What if one log shows you flew way over the 400ft threshold?
What if a log incorrectly showed you contributed to a crash and DJI wouldn't honour the warranty?  

I'd rather it be accurate personally.

DJI input awaited and would be appreciated.

My guess is that barometric pressure is used (rather than GPS elevation) for what is reported there. I have never seen GPS elevation off that far but I have seem my barometric altimeter off considerably.  The other possibility is that it is GPS elevation but that it is calculated before a stable fix is achieved. I have seen my GPS report erroneous elevations when it first starts up.

I've just taken a short flight, my ninth in total, and the max speed has reduced to 16mph.

May I please have some official DJI input?

Top altitude has now risen to 7431ft which yet again, is completely unrealistic.

How much of this app can I trust?

Can you offer any guidance DJI?

I've forwarded it on, I don't know why it's like that.
Mine is different as well.

Okay, thank you.

The top speed also dropped from 23mph to 16mph but now reports 23.3mph, following a weekend of use.

Hello,
I tried clearing the log and it did return to zero.  Unfortunately this will only work if you never sync again.  The next time I synced, the numbers were screwed up again.

In my case, when I cleared the flight logs, the 15,000 value did not return but obviously current altitudes would show up so if I get another too high altitude, it will of course show up.

Syncing does not bring back old values.

I agree--I get that impression but it would be nice see some documentation on what this really means.
