It is just not understandable the logic of deploying the jobs. The Buitenveldertbaan is called the secondary job but then it is used for both landing and taking off during peak hours ( or so what they said ); and since these peak hours are basically one after each other, it goes like non stop for whole day on Buitenveldert. At one time you think that it us finally over but nope, suddenly Buitenveldertbaan becomes the primary landing job (again in already weeks). No clear explanation or correct measurements are taken. Schiphol can just do whatever it wants now?
