Happy New Year to all!(I had already posted my question in response to an old thread but think it better to post under a fresh title)After a long absence from FS, I am rekindling the spirit, but have forgotten my latest moves before the "sabbatical". So I have some difficulty tracking this issue.The symptoms: some airports are no longer selectable via flight planner or "Create flight". Selecting them results in a N89:30 E00:00 location. However, they do exist inasmuch as they are visible on the map and if I drag the a/c there, the scenery is complete, the tower responds, etc. These are original FS9 airports, not third party add-ons. Without having done an extensive search, it appears that the missing airports all lie in a specific (rectangular?) area; e.g. Paris, Strasbourg, Geneva, Basel are OK but Lyon, Nice, Marseille are not.I am reluctant to do a clean scenery reinstall because of all the add-ons I don't want to lose. If someone can think of a quick fix, I'll be most grateful.Thanks!Phil

Hi,You added some AFCADs which have a different name for the airports.Thanks,Jimhttp://www.hifisim.com/banners/hifi-community-sigbanner.jpghttp://www.hifisim.com/

Hi,This can be due to a rogue scenery file. Try deactivating all addon scenery layers in the scenery library (including the Addon Scenery layer) and then restart FS. If you can now go to those airports, add your 3rd party scenery layers back a half at a time. Then divide and conquer to find the scenery that's causing the problems. Note that this can be a scenery across the globe!Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

Thanks to Tom and Jim for their answers.I'll do as suggested.Phil

There are some scenery installs that modify the default APxxxxx sector files. This could cause a problem with recognition if it still occurs after you deactivate your add-on sceneries,
