Hello Bernhard,
Yes i use scenery from Rhône-Alpes Simulation and they are real good.
In the mean time i've received 2 afcad files from Claude out France and they are working so far.
Now i've notice that it comes with another problem and that's the height.
I have geomodif, exclude files active in FS2004, but if I roll on taxi and runway my aircraft is follow the Mountain contours and crashes.
So i have to sort that out now. I can't remember having this issue before
