If you have previously download the airspace file for anything other than LXNav/Seeyou CUB format please Re Download and use the new versions.
The XCSoar file was badly formed, while the openair version will work in XCSoar the new SUA file included (ClubClass2018_XCS.sua) will display better)
The Airspace files for the openair format for the LK8000 and Winpilot have been updated to V2. Please use these and NOT the ClubclassLXNav_openair.txt available in the Airspace Files whiich is auto generated. While the usable airspace is identical the LOA layers which were included in error have been removed.
The CUB format for the old LXNavigation LX500,7000,7007(c) has also been updated but the change is minor (Removal of Shuttleworth DIplay Area).
The airspace file is available in the downloads section or from
