Poc ATC costs us over $600 m a year. It's main purpose is to prevent accidents.
A most common form of airline accident is a CFIT.
In all leading Aviation countries I have flown in a procedure exists so that ATC is used to prevent CFIT accidents in radar covered enroute airspace.
A procedure does not exist in Australia because all enroute airspace below 12500' was previously the responsibility of radio operators who were not trained or allowed to use radar.The procedures have never been updated because of resistance to change and a lack of an ethos to copy proven success from others.
There will not be 80 alarms- there will only be an alarm from a pilot who has failed to report visual or is about to die.
Keep your mind closed until 120 people die at Proserpine, Canberra or a similar airport with good radar coverage and mountains in the vicinity. I hope it's not your family.
