Quoting EMIT:-
One such speed fluctuation caused AOA to increase to Alpha protect, etcetera.
There is no occurrence of the ERRONEOUS speed values that AF447 experienced, no LOSS of valid speeds, etcetra.
Oh dear, EMIT
.
AF 447's speed readings were 'fluctuating' too; I don't somehow feel that it matters whether they were also 'erroneous' or not.
"The cases are completely different."
My own feeling is that there appear to have been only two obvious differences beween the two cases:-
1. The A340 only zoom-climbed at 6,000ft./min., whereas AF 447 zoom-climbed at 7,000.
2. The A340 crew were fortunate in that they were operating in daylight and no doubt had a visible horizon to work with.
But OK - if the 'systems' didn't cause the AF447 upset, what (in your opinion) did?
