KFLog and Cumulus only support the OpenAir file format for airspace structures. But we do not provide such files here in the map room. Please search in the Internet for files of the region where you do fly. Adresses where you can find information maybe:
- Worldwide Soaring Turnpoint Exchange Airspace
- Deuschland Airspace Data of Germany published by Deutscher Aero Club e.V. (DAeC)
Just download the files you need and install them into $HOME/[KFLog|Cumulus]/mapdata/airspace/ or to your selected map directory. For Cumulus please have a look into the online help to find the right install location.
