I don't think we need sources for this one, when you look at real world flight schedules, it should explain enough. When you look at SDU, you'll see the 737-800 (The 737-800 SHort Field Package especially), A320(neo) and E195 are all scheduled at the airport too. Most of these planes have the capability to take off from shorter distances in real life...but not in the game. I think most of runway lengths in-game are based on take off rolls when the aircraft is at its heaviest, which is quite bothersome. Because why can't a 777-300ER land at Dublin, but a 777-300(non-ER) can?
I think we need to use the min. runway usage or the average runway usage.
