wingletflyer . . ."I am also searching a clue suggesting that the A/T system was designed to switch to the correct RA in case of false reading. So far nothing...

Don't you see a semantics problem with your statement? What logic would apply in differentiating whether RA1 or RA2 is reading correct altitude? How would RA1 "know" that its value was incorrect? How would RA2 "know" that its value was correct? I think that what you want to research is if one RA becomes inoperative [red flag] that control will be switched to the other RA?
Who said that there was a flag indicating the RA1 failed? The RA1 was simply showing -8 feet with NO FLAG! On the other hand what you say it's true. Who is checking whom with what reference..
Would be nice to have a simple miscompare feature build in RA system..
