The DJI skysafe geofencing map says that to fly at my location of choice this morning is just outside an enhanced warning zone, since it is 8.37km away from the local airport. It is, however within the CTR1 cat D airspace of said airport, from surface to 3500'

Safety is paramount, so I contacted the tower and was granted permission to execute my planned flight. no problems with that so i pop the drone up.

I could fly it manually (wi-fi mode) without any issue, but when i set it to active track, it would disengage, complain about restricted airspace and on one attempt, it even dropped altitude to about 6'.

is the mavic misreading the DJI flysafe map:    http://www.dji.com/flysafe/geo-system/map
....or is it looking at an air chart:   https://skyvector.com/

What's occurring please?

When I fly mine it tells me there is a unpaved runway nearby, I am a pilot and have never seen an unpaved runway b sight or on the charts. The one open field here may have been a runway over 20 years ago but it has not ben in use for at least the past 15 years.  So I am not sure where they are getting the data

Does your mystery runway show on either an air chart or the dji link in my OP?

Joe, most civilians call the "unpaved runway" a highway. Only DJI thinks it's a runway. LOL

No not on any sectional charts  
I am guessing it is an old runway that was never removed from the data base DJI is using

Is it on the dji flysafe map though?

If you see any errors, you can email FlySafe@dji.com with the GPS coordinates.

Can you post a screenshot of where your flying, both from the app with the warning and a computer screenshot from the FlySafe page of your area.

Thanks for your interest Ken, I hope this is as you requested.

screenshot from flysafe. for reference, this is approx 50km East of London, UK.
Warrnings received at X, not received where ticked.

both locations are restricted in the lozenge shaped surface-to-3500' airspace from the airport as seen here
