fsx-ms What is wrong with my New York airports?

[Dominicoben 0]

I'm having a very strange issue where my airports in New York aren't loading properly and there are problems with the scenery. I've removed Drzewiecki Design New York and the airports from the scenery library and reconfigured UTX, but there has been no change, and the default airports (of KLGA and KEWR) are still displaying incorrectly (as in the pictures below). Does anyone have any advice as to what this could be and how I can fix it? I would like to avoid reinstalling FSX at all costs...

 

Thanks

looks like you may have an AFCAD file somewhere that's conflicting. I suggest searching the ICAO codes for those airports within your FSX directory to find them.

looks like you still have some addon scenery areas active in your scenery.cfg...or the layers are in the wrong order?

Thanks for the suggestions, found the culprit; there were 2 BGL files in the scenery/world/scenery folder (AFX_KEWR_ALT.bgl and AFX_KLGA_ALT.bgl) that were causing the scenery problems

Those ALT files are "altitude correction" files.  They are needed when you install scenery that changes the elevation of airports because of the way FSX creates runways, taxiways, and aprons.

 

There is a freeware program, "Simple Airport Scanner" that will show all your addon airports.  The program calls the altitude correction files "pre-load files".
