Hunter is absolutely right. Round and round we go trying to produce the foolproof system, and we need to remember what they say about those.
As I said on 27 Aug here - all jolly good stuff, but we have - as 'standard' - 2 pilots and triple sets of instruments to allow us to try and determine the 'valid' indication, using Human intelligence. Trying to present yet another 'AI' system which will 'solve' the problem is asking for trouble, and also assuming that the human part of the system is:-
a) Going to notice
b) Going to understand
c) Do the right thing.
AF447 blows that out of the equation. Here you all are looking presumably at yet another set of chimes/mail or female voice messages/ECAM indications/flashing lights whatever. I suspect all would have been wasted in AF447 and they would have hit the SA with even more warnings.
Icarus rules, in a way? Don't fly too high, son.
