I think i have this problem as well, my wheels start kicking up dirt maybe 5-10 meters away from the end of the taxiway instead of starting when im on the grass. How do i check for duplicate AFCADS?
It looks like the problem I have whilst taxiing into stand C38. I need 40% N1 and as you can see on the screen there is some dirt. But this is the only place I noticed that. Maybe someone can check that.
