Hi,
One may ask:
What is the importance of this issue?
AS data affects the Stability of the System.
The importance is clearly recognized by the Designers in applying triple redundancy.
IMHO is unacceptable the FACT they are "failing" almost SIMUTANEOUSLY.
Redundancy is not the solution to elements that "fail together"
IMO this configures a SERIOUS and PERSISTENT "DESIGN FLAW" or even,
ERROR
AND VERY PROBABLY WILL BE CONSIDERED THE TRIGGER OF AF447 CASE.
The industry was receiving persistent warnings on this and the
crew of the previous incidents were capable to deal with and landed.
Murphy Law in this case used the "industry failure" and put other slices of the cheese in the "proper alignement"
