Quotes from DozyWannabe, in answer to BOAC's suggestion that the PF's sidestick position might be displayed on the PFD in flight, not just on the ground:
(1) "Again - to what benefit? Adding more data to the visual perception channel risks overloading it."
Yes, it couldn't be on the PFD, IMHO. But there might be an argument for a separate, small display. But this would be of little help to the PNF when the aircraft is near the ground, and the PF is struggling. In the latter case, tactile is the only way.
(2) "Why the need to know precisely and at all times what your opposite number is doing with the PFC when only one pilot is supposed to be PF?"
Only someone with command experience in a two-pilot cockpit can really appreciate the desirability of this traditional feature. (See my previous post of Jan 02 @1959Z.) It's particularly so when a trainee, or inexperienced copilot, is the PF.
