Hi,
The fatal problem is not that PNF didn't get what PF was doing at the critical time, it is that neither of them grasped the consequences of that action, despite all the warnings and instrument indications of stall. Why they failed to grasp that is a very very interesting question, but it has nothing to do with stick, because PNF knew PF was climbing - crystal clear from the transcript.
Critical time ?
It's interesting to add the time of the events
2 h 10 min 06
The flight control law changes from
normal to alternate.
I have the controls
2 h 10 min 27
2 h 10 min 31
Watch your speed
Watch your speed
Okay, okay okay I’m
going back down
Stabilise
Yeah
Go back down
21 seconds before the first PNF call ... (PNF knew after 21 seconds that they are climbing)
They are in the climb from all those 21 seconds ...
In this kind of event 21 seconds is a big lap of time ...
