I think the responses prove my point. Within each of my statements I allowed a wide range of possible conclusions; I don't think I changed any minds, nor was I intending to. I've yet to see a truly objective position, and it cannot be because the two "types' are just too identical, and the partiality depends solely on training, or Company equipment.
Bottom line: The Hamburg incident where Captain doesn't "see" FP input a 14 degree left roll until the very best he could salvage was sparks on the runway and a shed winglet. With duplicative controls, moving in unison, same result? My feeling is no need to visit the shop. And if that is correct (it may well be wrong), one type is at least some of the time, a single seat A/C.
