For standard airports, all the lighting points locations and types (and orientation) are computed by terragear and then encoded in a simple format.  This is read in by the "btg" loader and then lights are created dynamically on the fly by FlightGear.  The light creation scheme could be replaced with something that creates much more realistic lights along with the posts and all the other bits.  But light position, type, and orientation is available for all airport lights<ref>{{cite web
