It would be nice if the airport selection map for both pilots and controllers indicated which airports were already manned by ATC. In addition, a range legend at the bottom of the map indicating the current zoom setting would be useful. Many times I’ve spawned at an airport thinking I’m 150mi away from my destination only to find I’m 30mi away.
In the pilots selection screen below, LIPZ is manned by ATC, but you have no way of knowing that from the selection map.
Similarly, no indication that its open in the ATC selection map.
