Howabout. C above D is clearly upside down. The collision risk is clearly higher closer to the runway. Why would you drop to a lower ICAO classification closer to the runway?
How does a single controller at a place like Albury operate class C effectively at 8500' when there is no primary or secondary radar to show where a VFR plane was in the Airspace .? Couldn't the controllers attention be taken away from the runway and the circuit area where collision risk is far higher?
I agree C is clearly safer when used as it is in the North American system where it is properly manned and with the proper survailance equipment.
If it was E link airspace at Albury it could stay 24 hours a day. As C it turns to dirt road G from 8500' down when the tower closes- crazy.
Why does Broome have NAS E over D if it is unsafe? Why don't we standardise like other countries? I know.
We must never change anything.
