Knackers, it is so sad. You obviously don’t know how Class E airspace is supposed to work. Class E airspace in the USA works identically to Class G airspace when VMC exists, and identically to Class A airspace when IMC exists.
You may have noticed that in Australia, people at CASA and people at Airservices who resist change have prevented Class E airspace from being used properly. In the USA, if an aircraft is about to be held or diverted in VMC in Class E, one or the other pilot simply reverts to VFR. This then gives a traffic information service between the aircraft, and this of course is identical to it being Class G.
What you are saying is that to solve the problem in Australia we should convert the airspace back to Class G – i.e. not have the advantages of Class A and full separation when IMC exists! Wouldn’t it be a better idea to train pilots and air traffic controllers so that when in VMC, one or the other IFR aircraft simply reverts to VFR, takes a traffic information service and is not held or delayed.
I believe the problem exists because in Australia before Class E airspace was introduced we only had controlled and uncontrolled airspace. There are some pilots and air traffic controllers who simply can’t believe that the most successful airspace in the world can change depending on the weather conditions and the professionalism of the pilots and air traffic controllers.
Most of the time, Class E airspace in the USA operates as if it is Class G. This is because most of the time in the USA, VMC exists. One pilot will simply use the advantage of cancelling IFR or climbing VFR, receive a traffic information service and not be delayed. One day in the next three or four decades this will happen here and Class E airspace will be operating correctly.
