The problems have occurred because crazy differences like two mandatory reporting points were introduced.
How will Class D, in any form, solve this?
At places like CN they have the luxury of being surrounded by Class G and can accommodate 5 IRP's, but BK is constrained by Class C to the east and military restricted to the south. I might be missing something but without considerable airspace change around some terminal areas, I dont see how Class D will solve the above mentiond problems. Surely you still need segregated inbound and outbound tracks for VFR aircraft?
That appears to be completely incorrect based on 'quoted' information regarding the requirements of an 'Air Traffic Control Service' & 'preventing collisions' posted on another site regarding this subject
.
Im sure that site has it's merits, but I think AIP might trump it when it comes to ATS provided in airpace classes
In Class D airspace, IFR and VFR flights are permitted and all
flights are provided with an air traffic control service. IFR flights are
separated from other IFR and Special VFR flights, and receive
traffic information in respect of VFR flights.
