looking for the cause(s) of the cabin confusion
From reading the available transcripts I get the feeling that the software played a role in disorienting the pilots.
My understanding is that as the pilots approached zero forward air speed, there was an audible alarm, but once the pilots achieved something near zero forward air speed the stall warning was silenced.
From then on, the warning was inverted. Pushing forward on the stick (and causing the plane to recover some air speed) caused the stall warnings to sound again. Pull back, the warnings are silenced.
Was this a contributing cause of the cabin confusion?
