Khartoum is Khartoum. If you stick on the yellow line, you will hit the other aircraft in their parking bay and if you taxi off the yellow line, you will have a main gear in the mud. It's a no win situation. That's the beginning of the story, and then to get start and taxi to backtrack and line up, well, you gonna be there all night from experience with the A332.
Khartoum should be an A320 only, 1 flight per month on a sunny day airport!
