i can unterstand this and it´s ok so.
But i would have another idea to improve the capacity of airports with two runways, when an airport will build new, and this should have two runways or more. Please choose for landing planes which one, where no airplanes have to depart or crossing also.
Background: The time a runway is occupied is for landing planes longer, than for departing. If so the landing runway is used for other movements, the capacity of planes who can searved will be reduced massive.
For example: in MCT and LHR also could be more planes at a certain time handled, when the use of runways would be changed generelly. In LHR only landing at RWY 26R and departing/crossing at RWY 26L.
Maybe it´s possible to consider this in the furure.
