Dani and OK; well the checkee TRI was a gungho kickass type who wanted a few of the surprises. You have to appreciate all the aural/visual warnings the AF447 crew got; someone wrote a simple case of unreliable instruments............sigh. The A330 has SSGs, calvary charge, etc plus a host of ECAM messages when there are failures which lead to other degradations. All these are very hard and too much for arm chair know - it - alls to appreciate.
