So the full professionally trained crew did not comply with the company set requirements .
That's why I had a simple check system in place.
Whenever I see the details of an accident I always think " when am I going to do that". Not " I could never be that incompetent"
In Australia for over a decade I have been attempting to get the approach multilateration system in Tasmania to be used properly to reduce the chance of a CFIT.
Many airline pilots tell me that procedural approach is good enough because it would only be an incompetent crew that would let down prematurely and hit Mt Barrow.
I have not heard if one airline pilot requesting the Tasmanian system be fixed . They must think they would not make a Mt Erebus type error. I hope their self confidence is not misplaced .
