Thanks Scott.

Well perhaps we are a little restrictive then. We do let GA into the zone but tightly controlled and I suppose that is the reason we are Class A - it gives us tight control. Gatwick is Class D and still does okay but here too the limitation is often staff.

I would be interested to know how big your's is compared to our's! Our zone is barely large enough to protect the IFR. GA can legally pass 600' underneath our ILS traffic and still be outside the zone and outside our control.
