HC quite right
Gegg:
"The whole point of Class D is that ATC don't need to separate VFR from other flights."
maybe "should not try to" is an alternative.
Brize also will not allow VFR traffic to self separate from it's IFR traffic.
I guess the service being provided in Class D should be a 'Traffic Service' ?
The fact that VFR pilots have become used to being directed ('controlled') will cause a problem in the future.
