Delete an stock airport

but wait, there's more :)If the OP installed all of the files for LGAV, it turns out that the Hellenous group also instructs to install a bunch of base files first. I look at their contents showed that APxxxx and B something default files would be overwritten (with the old ones saved). Overwriting the actual tiled default AP files is something I don't allow since it can affect other scenery that depend on those. I can see their reasoning, however. The default scenery contains a flatten that excludes autogen from the airport territory. That is the reason that after taking out the afd objects and extra building scenery that LGAT turns into a vacant lot without AP and other default changes. I am not aware of a scenery object that can put back autogen objects if placed in higher priority than a flatten.Now if you look at maps.google.com searching for LGAT the satellite image shows the Olympic buildings (Athens summer 2004) over remnants of the runways. The description of the base files for all of Greece includes the statements that the Olympic buildings were installed and in reality at the time of the shuttle image that's what existed. So:1. What the OP complained about seeing autogen buildings over runways is correct (but they should be just worn surfaces and remnants) is correct.2. The flatten in the default can only be gotten rid of by modifying the default tile or individual scenery objects and textures besides the Olympic items to replace all of the autogen objects.I do have the HSP LGAV installed but never allowed the base AP files to be overwritten hence the flatten remains resulting in the LGAT vacant lot appearance. The Olympic structures are in the base files.A search on flightsim.com revealed photoscenery is available for the province(?) of Attica where Athens resides so that may provide a realistic base to cover the flatten.So, I think the OP is seeing in the former LGAT area what is supposed to be there by the way the overwritten base files got rid of the flatten (and probably the afd objects in that area). It was still correct for us to get rid of the afd objects, communications properties, etc. Also by HSP modifying the AP base files LGAT was eliminated from the default GPS and also the airport dropdown in creating a flight.It is something that is not easy in this specific case.HSP did a very good job getting what is there and working around the limitations of FS.
