If the PM is actioning the QRH and doesn’t realize that the forward-moving trim wheel is NOT being moved by the PF, I can see a situation developing whereby a breakdown in communication could lead to a massive out-of-trim condition with the PF waiting for some sort of QRH-led solution to be forthcoming.
I can see this scenario happening...quite easily...and quickly. Many are pontificating the need to cut out the stabiliser trim and run the stab trim runaway items...that’s easy to say in an armchair when not faced with multiple, confusing sensory inputs.
The idea that this STS system can continue in action after faulty AOA-data driven miscompares, is odd. IMO
