Basically anyone that is willing to pay the consultants and apply's for controlled airspace is going to get it in the current state of play.
It doesn't matter what anyone says or how stupid the amount of air they want to grab they will get ruffly the same which will be a CTZ with 5 miles either side of it by 8 miles off the end of the runway up to 3.5k feet. The areas outside that which reverse wedding cake up with bits coming off to link into airways. Or not in the case of Norwich.
As with Inverness's case sometimes the amount of airspace they are given will mean you can go places which currently they try and bully you out of.
But realistically it matters not one jot what anyone says about the proposed airspace the powers that be will always say that Class D does not restrict the movement of GA and it is safer than class G. So any bitching that it will exclude GA users will be ignored.
Both Inverness and Farnborough will get there airspace.
After Norwich got it, it was pretty much obvious that anyone that pay's the money to jump through the hoops will get it. Mainly because if it was refused an subsequently there was a mid air nobody wants the finger pointed at them to say they are to blame for refusing the application.
