I have been playing for a few weeks now and I’m enjoying the game, however it really annoys me how long it takes for large and especailly extra large aircraft to vacate the runway.
In reality they would be vacating the runway as soon as possible with some airports around the world mandating the preferred exit to maximise runway utilisation.
I suggest that where rapid exits are used the exit speed is higher and that extra large aircraft exit on one of the rapid exits rather then using the full length of the runway, so that no matter what aircraft they will all use one of the rapid exits. Adding to this would even be S/M aircraft using the 1st exit, L aircraft using the 2nd, and X using the 3rd.
This would enable a higher arrival rate, allow more gates to be used, and most importantly at single runway airports less queues (If Line Up and Wait is also implemented)
