I have just reinstalled FS9 on a new computer. When I want to change airports when creating a flight, many airports, although listed with ICAO code, are not recognised and I end up at a lat/lon close to 0/0. This happens with many airports but not all and the problem seems to be happening by regions (e.g. most of Germany seems to be inaccessible but Paris airports are OK).Of course, if I slew to the airport it is there all right.I have installed a few WOAI plans but I can't see the link.Is the mapping of airports to coordinates held in a single file that might be corrupted?Thanks for your help.Phil

That sounds as if you got a "bad" install - especially a great many of the files in your default Scenery folder. The default airports are kept in the many files which start with the letters AP and each one of those has upwards of 50 airports in a given region.I would recommend you try restoring the entire default scenery folder from your install disks.These resources will help in that regard:http://www.cat-tamer.com/flightsim/faq001.htmlIt shows where everything is on your install disks and how extract just what you need.I also recommend fs9cddir.zip Compiled by Brian Collins (available here in the library)This is an Excel format listing of all the files on your install disks. A great resource to keep handy.Good luck and please let us know if this helped.

Thank you so much for your quick response. These references will be most helpful as I'd like to keep a full reinstall as a very last resort.Regards,Phil

If the time comes when you do need to un-install and do a clean re-install, I think you will find this file useful:http://library.avsim.net/esearch.php?CatID...amp;DLID=123907Good luck!
