Manchester area then hand you off to London who want you up at FL310 50 before Midhurst - try doing that in a heavy A321!!
They then promptly cancel the Manchester speed restriction because they want you out of the way and would rather you make as high as you can get, regardless of speed, which makes a mockery of the speed profille in the first place.
These ideas are not made up for the fun of it. As I understand it, there was a lengthy discussion process with all the airlines involved in this speed trial, and they all said it would not affect their ability to make existing level restrictions. If you are finding that this is regularly not the case, then you should be feeding that back to your Flight Ops to progress with NATS Ops.
