Hi all there's a working version (including the spellchecker on unix - thx to Kuba) of Openairspace parser in the library folder in master. The interface will be modified further according to the needs for the airspace drawing engine (yet to be implemented). If anybody finds any problem with building the library, pls let me know. Next I'm going to start implementing the mentioned airspace drawing engine in cooperation with Maria as she is the one having most experiance with osge so far. brgds Ales
