I downloaded a bunch of nice mesh files for the Himalayas and a few airports from the region. One airport that I snagged was ZUNZ which listed itself in Tibet. I then set to make some flight plans. I inputted that airport and it showed up on the list. But the sim wouldn't allow it to show in a flight plan. Sure I realize Tibet is part of China but one would think if it showed in the list it would go in a flight plan but no go. Anybody know what the problem is or how to fix it?
