deceived by the information they had and a severe lack of personal knowledge of the physical geography they were overflying
And with that severe lack of knowledge they decided to descend to 1500ft, trusting on the AINS for track guidance. They certainly knew Ross Is and Mt Erebus were close, but they never sighted them once, certainly not enough for a positive identification of their position.
It has been established without doubt that the AINS was not to be used for Nav below route MSA.
The route MSA was the same no matter what the final waypoint position was, the TACAN or the head of McMurdo Sound, it was FL160.
The safety systems of Air NZ failed the crew not the crew Air NZ
That statement has been proven wrong so many times by so many eminent people, including Judges, Airline Pilots, Aircraft Accident Inspectors that the only people who believe it to be correct are obviously lay people with no knowledge of the workings of Civil Aviation, Paul Holmes being a good example.
passengers already paid for their mistake with their lives
And what exactly was their mistake????
