No Dubai scenery before.
The aircraft goes underground soon as I have done a flight planner (Dubai Int as a start airport or destination). If I start the game with out flight plane the aircraft are above ground as normal.

So this only happens when I have a flight planner.

Thanks, where shall I start looking?

Why are my aircraft underground every time I'm flying with a flight planner?

Im using FSX, Ultimate traffic 2 and REX Essential.

I have some problem with my AI-Traffic. When they are entering the runway 12L/30R they don't ask tower for take off clearance. So every aircraft lines up at the runway and stand there for some minute until they disappearance. Meanwhile they are standing on the runway aircraft use the runway for land...
