There is not much information here. If you tell us what cost us fgAirportDBLoad in the whole initialisation process, we could decide if it's worth optimizing it. And you're missing a bit of history here : The airport file used to be binary and it was decided that a text file was easier to maintain. No endianess or integer size problem, no compilation phase. MetaKit was a PITA at the time. -Fred -- Frédéric Bouvier http://frfoto.free.fr Photo gallery - album photo http://www.fotolia.fr/p/2278 Other photo gallery http://fgsd.sourceforge.net/ FlightGear Scenery Designer _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
