Hello all,

I run FSX SP2 with the acceleration pack. I just encountered this problem the other day and can't seem to fix it. It started when I installed KSGU addon scenery from avsim. It seems that is has messed up the default terrain height as it effected KABQ as well. With the default KABQ terrain covers runway and taxiways and with the Tropicalsim ABQ there is no runway or taxiway markings and the terminal sits lower than it should. Is there a known fix to this or do I need to reinstall FSX?  https://imgur.com/a/EmetoQ1

What are your scenery sliders set at in the sim? Mesh resolution can have an effect. Don't re-install FSX just yet!

Airports on plateaux or in holes usually indicate a terrain mesh issue. The more detailed the mesh, the more you see the compromises made for FSX stock airports and some freeware versions may not address these. You mentioned that you have an airport from Tropicalsim (payware?). What are their recommendations for the FSX scenery settings - that may resolve the issue.

Level of detail radius: Large

Mesh Complexity: 38

Mesh Resolution: 10 M

Texture Resolution: 7 cm

Tropicalsim doesn't have any recommendations for settings in the manual but maybe I'll contact them and ask. 

Add-on airport altitude set incorrectly for the terrain mesh is my guess.  Are you using an add-on terrain mesh?

In addition to the terrain mesh issues mentioned above, for some simple troubleshooting you could just de-active KGSU in the FSS scenery library and see if KABQ is  displayed correctly. This will narrow the issue down.

Also whats the order of your two sceneries in comparison to any terrain mesh you have installed in the Scenery Library?

You don't say which of the several KGSU add-ons at AVSIM you used, but the first step should surely be to remove that scenery and see if that fixes the problem?

The problem you’re having is usually caused by two issues. First issue could be terrain as mentioned by others. The other issue could be an airport elevation correction file missing. When someone creates a new airport replacing a default one and changes the airport elevation, there has to be a airport elevation correction file to override the default elevation. This file does not go with the rest of the scenery files, but instead goes in the “scenery - World” folder.  I would first check the readme or instructions for the airport that you got from AVSIM and see if mentions anything about a elevation correction file and where you should put it.
