Doesn't this contradict your own statement? The computer (decides to) 'gives' GS IF the pilots do/had done ... So it is the computer that makes the decision here, ignoring completely that one of the human inputs was incorrect...
No. You can't ignore that the human input is likely to have been incorrect. If the lever was left forward, then the operator failed to correctly specify his intentions to the machine - and that would have been the case in any aircraft.
If the lever was left out of position, then it was a gross handling error, period. You can't blame the computer for that.
It was AB's decision not to make the adaptation mandatory, and the aviation authorities apparently didn't see it fit to override this decision. Had they overriden it, perhaps this accident would never have happened.
Must have missed that - could you point me to the relevant paragraph?
Cheers.
