During the last three flights the Flight Log has stopped logging data during the flight. Flights are uploaded to Airdata then the CSV is downloaded. The DJI App shows the Mini went up to 90 and 110 meters, but this is not reflected in the flight log.
Both CSV file and Flight log txt file seem small for 5 to 10 minute flight.

Your flight log recorded properly (as it always does).
Airdata just downloaded partial data.

Directly load the flight data into something like CsvView to confirm that the data was recorded properly.

His data was recorded properly.
The issue with Airdata downloading partial data is quite common.

I've never used AirData - so was unaware that there is an issue with it.  I use CsvView to look at my data locally.
I had no doubt that the original data was correct...

Hi,

Interesting....is the middle part missing?  so start and landing is in the log ?

If you like post a cloud link to your log on here, so i can have a look at it.
In the middle part is missing i be really interested, see if i can find a trigger in the log wich result in airdata not converting correct.

Or PM a link of your log to me.

cheers

Start is in the log, missing landing.
Sent you a PM with data

I think I may have found the cause of this problem. The flights where the logging was incomplete was just in the range of my home WiFi system. With the Auto sync function turned on on the IPad Mini, maybe, just maybe, the flights were being synced during the flight
Went flying again today to see if problem still exists. No issue with sync to DJI cloud, then uploading to Airdata, then downloading the XLS file. All data from start-up to landing is there.

Thanks JJB. Lookig forward to the release of updated FRAP32

From what I found today, the data was missing from the flight log, not an Airdata problem.

Your flight data is not incomplete.
If you re-sync the file manually, you'll find it's all there.
Airdata picked up a partially synched file.

Hi,

I will sent a link for a download of the latest FRAP, try and give it a user test...
It is for 95% working.

I have never seen any case of missing data from airdata.com. I have noticed missing video from the drone however, usually about 30 seconds between files.
