Tunnan,
You surprise me.
It is clear that the QF 737 was in the wrong place at the wrong height, well below the LSA for the area.
You say “Luck had absolutely nothing to do with the QF incident”, as if you are saying the EGPWS was a primary terrain avoidance device.
Sadly, if you look at the human factors history, warnings are not always heeded, all too often they are treated as “false warnings”. And by the way, I am all too well aware of the potential shortcomings of the EGPWS, even though it is a great improvement on the older LRRA based systems.
Fortunately, in this case, despite all factors that got them where they were, the crew did finally react as trained. Other training should have prevented then being in the situation in the first place, but it didn’t.
When it’s the last hole in the Swiss cheese that didn’t line up, that too close for comfort.
What happened to several other slices of the cheese, positive surveillance from Melbourne, the radar on Mt.Majura doesn’t shut down when the Canberra TCU shuts, where was the TAATS terrain warning ?? During the slow hours, why does Canberra revert to G instead of E??.
Far too many things happened or didn’t happen here for any complacency.
