Lefty' You are correct -It's not as dificult to do as others make out It is more about resistance to change than anything else.
A MSAW alarm is considered by controllers in other countries to be far more serious than the many types of route monitoring alarms and is so acted on.
Hardly ever will there be a false minimum altitude alarm as it will only sound if the plane is below the legal minimum altitude and has not reported visual or cancelled IFR.
We are so behind international safe practice that we have not even introduced the correct procedures or terminology so this can work in radar covered uncontrolled airspace.
When this airspace was the responsibility of Flight Service Officers they were not permited to use radar so the could not provide a MSAW service and there was not the need for any pilot procedures.
There are new young controllers comming along who believe that this safety feature should be introduced into Australia.
