Surely the point in having more than one crew member is so that the PNF can say either:
1- What the fxxx are you doing or;
2- What the fxxx is IT doing depending on whether your are requesting the right or wrong inputs and getting the right or wrong responses from the system.
So, in the Bus, can the PNF or jump seat occupant see what the PFcommanded with the stick? If not, do not expect them to be able to call you on it.
Could someone who flies this confirm the simple question
"Can you tell what the other is doing?"
Frankly I am impressed with the self restraint of a PNF who waited 27k feet before deciding to put hands on. I stop being a team player way before that
