Firstly I would like to highlight that this wish list commencement has not been mentioned on Steam at all, so all the users on Steam that don't know about this forum will be missed out!
I only stumbled upon this topic when looking for a solution to an airport problem.
My wishlist in no order of preference.
1, No bugs on final release.
2, No multiple penalty for same single event.
3, A sound played when an alert for a collision is shown (for 2 screen users busy lookimg at 2nd screen)
4, Remove red light from top of tail on airliners, should only be on GA aircraft
5, Ability to be able to rotate ADIRS to fit screen.
6, Option to remove road traffic.
7, The ability to narrow down gate assignment for landing a/c, to aid taxi route planning.
8, Large aircraft like A380 not being parked down alleyway, possibly size gates to avoid this.
9, Ability to taxi an aircraft from runway, even though its gate is not free, possibly to a holding point, instead of blocking the runway exit.
10, Once an aircraft is no longer visible to the eye, camera not to turn and focus on it when selected
11, Option to assign another key/joystick button for push to talk.
12, Better core code optimisation for cpu and graphics chips.
13, Random delays capability instead of fixed timetables that can become predictable with use.
14, Aircraft towed off gate to go to remote parking capability.
15, Not have a A380 land the same distance as an A321
16, Ability to taxi an aircraft to a holding point for a runway, or just a holding point to make room for other a/c.
