09L,
As far as the 75 is concerned, it is not just the high vortex, the darned thing is also very slow on short final; yes, I add a bit on behind but a take a bit off in front and that way you don't find 73s only 3 miles behind it as it touches down. Safety is enhanced but the landing rate doesn't change. I think that is a reasonable and professional way to go about it.
I'm intrigued a little by the above. You increase separation behind the 757 but reduce it in front. Do you only do this when you've agreed 2.5nm separation with the tower in advance or would you do it anyway because it is another of your own rules?
I honestly have to say that no KLM has ever asked me for increased spacing behind a 757. They used to ask all the time on departure when I did the tower, but never on arrival.
Our senior manager must have been very worried, especially as every year for the last three years the declared capacity has gone up
