Problem Antelope Valley Edwards Final Approach scenario not working in D3D9

[SpaceBoy2]

The Edwards Final Approach scenario under the Antelope Valley folder has two problems while running in D3D9 client. It's works fine in DX7: first, the runway and base tile doesn't load until much closer. Second, the terrain collision happens while above the real ground just about 100m.
What can I do to fix it?

Thanks for the report. I'll take a look at it when I start working on some other elevation related issues.

Thanks but I ought to mention I'm running OpenOrbiter (Orbiter Beta?) and Beta D3D9
