Just a thought - but why do Airbus allow spurious, low-importance alerts (like aircon) to give audible warnings within a short time-frame of somewhat more important ones (ground proximity... terrain...). Surely there couold be a list of warning that just push the rest into the background until the comuter can see thigs are a little more normal (ie on the ground or with AP engagement parameters) I'm not trying to write the software but you catch my drift?
If these 2 are dumb enough to use the same table look-up via bookmark on a vital independant cross-creck, rather than actual check for themselves, I am not so sure it was anyting but human error
