Speaking purely as an interested observer in all things PPRuNe, if those sitting at the sharp end are unable to agree about actions to be taken when fault advisories are annunciated from a FD, then does this not suggest that there is something wrong with the 'system'? If the end always justifies the means, then it would appear that the pilots made the correct decision, however had the same event(s) a decidedly different outcome, what course would discussions have proceeded along then?
