Moist,
If the controller's asking you to keep up your speed then that's fine, he has removed the speed restriction for PLANNING purposes, I thought we didn't do that!!! Just because you can do it, doesn't mean you have to.
EDI is the slowest handling airport FACT, you say..... back this up please, I'd like to see where your info comes from.
As for things changing, until pilots like you are more constructive in your arguments quoting reality (Fact) not opinions then no-one can move on in a safe and expeditious, not to mention friendly environment. Maybe try putting things forward in writing to the unit or through your rep at the local safety meetings (or whatever they're called) until then expect more surliness.......
