Hello,I'm having a #### of a time trying to figure this out. The default airport at NTMD _Nuku-Hiva is in a hole. It should be at 1400ft but the default is at 200ft.I modified the AFCAD as you can see in the photo below. So the runway is at the right altitude. But all the terrain around it is still way below. the runway, see:I don't know what to do. Can I exlude the entire default airport including the flatten? How can I fix this?Thanks!http://www.cpavirtual.org/images/banners/MyNewCrapBanner.jpgEric Thornton - CX001

What you are seeing is that airport aprons and taxiways create local flattens around them. But the rest of the airport also needs a flatten at the correct altitude. Note that you might have AI aircraft trouble too.I use sbuilder to create flattens, but there are other ways. You could create a scenery area and use a flatten= line in the scenery.cfg for instance.Attached is a small flatten bgl that you can try. It is set at 426.719 m.scott s..

Sweet!I didn't know you could raise flatten terrain higher than the default flatten...Thanks man. :)http://www.cpavirtual.org/images/banners/MyNewCrapBanner.jpgEric Thornton - CX001

That did the trick. I thought it was more complicated than that, lol.I should have asked here first. :Dhttp://www.cpavirtual.org/images/banners/MyNewCrapBanner.jpgEric Thornton - CX001
