Herr Doktor,

You miss one important fact...

As history tells us, human perception is not perfect. Accidents have occurred in which, despite the difficulties around understanding human performance, investigators have shown that illusory visual cues played a part.

It is far too early to judge that happened at EDFE, and I am sure the investigators will do their best to establish how the accident happened. I hope and trust that they will consider the possibility that the pilots may, legitimately, not have realised the gravity of their situation. This moves the causal factor from the flight deck to the regulations, perhaps.

By the way, I fundamentally disagree with your 75% claim as put. You are mis-stating things. Let's put it another way: all accidents blamed on human factors are proof that regulators and designers have failed in constructing the error-tolerant systems which aviation demands. We have not correctly identified and implemented the 'acceptable error' level...

Tom Imrich is right, technology should help to eliminate all the accidents we see in non-precision and visual approaches, but regulators place VERY high demands on integrity.
