Screen right list plane restrictions?

If there are a lot of planes behind, even if ready to land, is there a case where it’s not on the list? When doing it manually, even if you want to prioritize the player’s plane, there’s a situation where you can’t because it’s not on the list.

Yeah, that happens when u have more than one plane schedule at one stant, so if both planes arrives at the same time u will only see the first plane scheduled at that stant and the other will disappear and not appear until the first plane reaches the stant. U can solve this by removing the plane u want to handle first off the stant or just putting that plane above the other.
