HUGE difference :
- One is fully obvious to all in the flightdeck.
- The other is simply unvisible to all PNF.
Yes, I understand this. But in that situation the PNF or the Captain should still be observing what the PF is doing. There should have been open dialogue between the 3 and the Captain should have taken a leadership role. From what we read this was not the case. Furthermore they are all AB pilots and understand this and should be able to work around it with that knowledge....
