Workinghard :-
You say "Please also be aware that by a very large margin GA accounts for the majority of aircraft movements in the UK"..... That may be so , but it would need an awful lot of GA movements to equate to the number of people on a B737 wanting CAS protection. As CAP670 rightly says, it is "an issue which is primarily one concerning the safety of the travelling public. "
The military & AOPA are currently on a winner because no MD can afford to shout about lack of protection around his Airport - but I bet if a crusading Sun reporter told Joe Public what goes on , there would be a lot more CAS very quickly !!
You also say "and therefore places such as Doncaster, should it aquire class D will do so at the expense of the MAJORITY of airspace users."
Why do you say "at the expense of" ? Maybe in some areas , GA is delayed or kept out of CAS for traffic reasons, but if it's that busy, can you be confident you can fly safely through it anyway if CAS didn't exist ?
Supposing Stornoway wanted Class D airspace to protect it's instrument approaches - who would be the majority affected by that ? The blanket objection to CAS by certain organisations does them no credit !!
Rant over :-)
