You know what Dick, I totally agree with you. I really do.
Do you have costings for the implementation of E airspace right down to control these approaches? It must be quite high I am sure you will agree. I am not saying not to do it based on cost, just want to know the cost.
Lets use an example of an IMC day along the coast between Sydney and Brisbane. As you often state, a D aerodrome controllers responsibility should be near to the airport where collision risk is greatest. I agree. Take Taree for example which has no radar coverage below A040 and porr to no VHF below A020, will there be additional facilities required?
With the disposition of aerodromes, how many controllers will be required to give full attention to each and every approach in the E (which is actually A in IMC remember?). No need to give me an exact number, just More, Less or Same with your reasons for that selection.
