More importantly. The reason we are not using the existing radar rated controllers in the Melbourne Centre to provide a proper radar approach service into Launceston is because we can't change to the system used in leading aviation countries where the tower controllers just concentrate on the tower airspace where the risk is highest.
No doubt in the 1950s or whenever Launy tower went in the tower controllers had huge airspace to 30 miles or so.
So we must never change that. Leave the 1950s procedures set in concrete for ever even if it means keeping procedural control with its clear lower level of safety.
What a complete waste of $6 m of our industries money for the multilateration system. Yes. I have heard the AsA lie - that it was never intended to operate in terminal airspace.
