Hi Misson,
That's one of Steve McClelland's airfields. Steve's bases are not separated - they are contained in large BGL files - one or more for the scenery, one or more for the flattens and one for the AFD data, e.g. euro3.bgl.
He did three packages for Europe:
one covering the continental CFS1 bases - this can be deleted as the airfields are superceded by Achim's ones;
one covering Spain and Portugal - this can also be deleted as the Spanish airfields are also superceded by Achim's ones;
one covering the FS2000 airfields of the British Isles - a few of these airfields are superceded or their location conflicts with other scenery. The files can either be kept in a separate scenery layer which can be deactivated or, as I painstakingly did, decompile the BGLs and remove the offending airfields. Some of airfields are on plateaux or in depressions if you have Rhumba's mesh. There are also files covering highways, rivers and lakes in this package. These are not required.
Cheers,
Kevin
