Just a quick question.
If Manch. en-route airspace is to be done by Prestwick, or some sort of resectorisation between Prestwick and Swanwick, shouldn't NATS be doing some "change management" and have a proposal up for scrutiny in which the transition of airspace from one centre to the other centre/s occurrs? This should invovle consultation with the ATC union, NATS management, etc. Has this occurred?
I'm sorry if I should obtuse, but it appears that either your union hasn't been looking after you, or that MATS management have ridden rough shod over you and you need to do something about it.
BTW, Oz approach ATCs in Perth, Adelaide, and Sydney are looking at moving to Melbourne in the next few years. If you thought Manch. and Scotland were in separate countries, moving from Perth to Melbourne might be something similar.
