NZFF

I have a problem where all my AI aircraft from different packages are floating a few feet at NZWP. I have checked the AFCAD file, checked the airport coordinates in the AI files yet planes still float.

Anybody know how to fix this?

This is normally what happens if you change the elevation of the airport via the AFCAD. Not too sure which sim you are using, but I would think that it's FS2004.
This happens because the AI are placed before the new AFCAD elevation is loaded, based on the default elevation. A quick fix is to copy the AFCAD file into Scenery\World\Scenery, so that the new elevation is loaded before the AI.

Thanks for that, still didn't work so I changed the airport elevation in the AFCAD to line up with the AI, seems to have worked.
