Look at this... Airport (WMBU) should be 90ft, actually it is ~2200ft MSL. I have found very similar airport somewhere in Africa.Is this FS Global 2008 fault? Is there a way to correct this? Approaching at IFR condition wouldn't be good there :)

Well, I have seen aistrips in holes in Africa without a mesh enhancement, so it could also be the fault of FSX.What's the airport name?

Terrain mesh does not provide airport elevation data to FSX (or FS9), as that is contained in the APXxxxxx.bgl files. Terrain mesh can expose improperly located or elevated airports. Most terrain mesh does nothing to correct these problems. Some does. :(

It is very easy, if you have FSX Deluxe/Accel and install the sdk. Use ADE9x to fix the airport.Typically, problem like this is either:a. Airport is at correct elevation, but wrong locationb. Airport is at correct location, but wrong elevationTo decide which, I did some Google and looked in Google Earth. It looks the situation is :(.So in ADEX I call up the stock airport, and first create an exclusion poly around the airport tagged as exclude airport background. Compile and install in FSX. Then start FSx and go to the airport and slew around the runway. In ADE, use the "connect" button to show the aircraft position. ADE will report the mesh elevation under the aircraft, so slew off both ends, and left/right a little and take note of the elevations. If the ground is sloping, you will have to make some compromises because FSX uses flat airports. Probably best to have the airport near the highest elevation near the runway ends so you don't have a cliff to fly over. In this case, I found elevations from about 31 -37 m. I selected 34.55m as a compromise.Now in ADE again, I use the tool "change airport elevation" to set my airport at 34.55. I draw a new terrain polygon around the runway and set this to 34.55m too. I can now compile the airport and place it in my scenery folder. This will result in 3 bgls: one for the airport, one for the terrain, and one to change the elevation (that one goes in the default scenery\world\scenery folder, not the one your other files are placed into). Start FSX and I'm done.Of course, once you start playing with an airport, the question comes can it be more accurate? So I googled around and found some pictures and AIP data from Malaysia and did some tweaking.scott s..

Thanks Scott for providing my the detailed answer with screenshot!Since FS Global 2010 is almost on the market, I will use its tool for correcting the rest of strange airports.
