I'll allow for journalistic mis-quoting, but where is the
evidence that
-- The aircraft flew into an area of storms which other aircraft avoided by steering around them.
- I was not aware that the precise track of 447 was known?
-- There was a malfunction in the ADIRU, the three air data computers which feed information to the flight system and the pilots?
I was under the impression that the ADIRUs were thought to have behaved exactly as designed, rejecting supposedly conflicting information - ie intially a detected IAS change of at least 30kts in one second?
It would be of significant interest to AB operators to know what particular 'malfunctions' were fed into the simulator in these tests, what sequence of warnings were generated (eg did you receive a cascading failure of ADIRUs?), and what instrumentation was then left available to the crew - eg did the standby attitude still function correctly?
I think we are all pretty much on the same track generally, John, but to state
categorically 4 primary individual causes of the accident is indeed a bold step.
