Frederik: There seem to be two sides here. Some want the aircraft to always go for the nearest runway no matter what. Some wants the system to divide between any available runways. They way it was before was kind of random so they would distribute evenly. I recently added a distance factor as well which is why some of you see a different behavior where they will pick the nearest instead. I’m open for input here.
Speaking for me, I believe that the distance factor has a negative and limiting impact on the way we design our airports.
In this system aircrafts choose the nearest runway relative to their parking stand. This means that several runways have to be placed equally close to the same amount of stands. Only so, congested runways are avoided.
Let’s use my airport as an example. In my airport design, I kept in mind that the terminal might grow in the future and therefore placed the second runway farther away. As a result, This runway is hardly used at the moment and the closest runway is fully congested.
In reality, runways aren’t either assigned based upon the location relative to the stand. More based upon wind, dep. route and congestion.
In short: This system puts the runway in the center of the airport design instead of the terminal. Equal spreading of aircraft traffic is the way to go for a realistic and unrestricted airport design!
