Rick:

Mechanically, it would be impractical to physically link the two sticks (the linkage would have to go an extraordinary distance vertically down each side of the cockpit, below the floor, then across the cockpit). I assume you are talking about using the type of "feedback" found in higher-end video game controllers. Possible...but would still require some hardware mods (to add to the side-stick).

What might be easier, and just a software change, would be to add a control-deflection indicator to the glass. Something similar to the Flight Path Marker shown on the Bus now.

If I were to design it, it would show some type of up/down arrow for elevator input, a top-of-circle arc that would show magnitude of aileron input, and a bottom-of-circle arc that showed rudder inputs. I think to avoid clutter, it would go on the right side of the PFR (an analogue to the ILS Glideslope being on the left).

Sorry to see by your 'Position' you're in the 'Died. How long you been, and how much to go?
