In P3Dv4.5 I had the airfield working well as EGCN, overlaying the stock airport, but I couldn't get it to work as well in FSX, so I decided to rename the airfield to its original EGXI, and delete the stock airport. That worked brilliantly for FSX, but the P3Dv4 version kind of fell apart at that point! I'm using Orbx England (not True Earth), and the removal of the stock airport has allowed some strange things to happen with the terrain elevation and penetration by autogen trees (see the picture). Yes, there is a proper Airport Background (Flatten, Mask Classmap, Exclude Autogen). On top of that are exclusion rectangles set to exclude all (see the ADE 1.76 screenshot). Yet the trees are all over the place and the airfield is anything but flat!
I've Googled the problem, and scoured FSDeveloper and the Orbx support forums. I've made sure there are no other versions of EGCN or EGXI interfering (Just Flight Global Traffic is a little tinker for injecting its own AFCADs!). If anyone has encountered and cured this problem, I'd be grateful to know how you did it!
