FBW
All flight controls, whether they be manual or powered or FBW MUST have feel. Early FBW side stick in F16 has a feel of 3 pnds per G up to 27 pnds for 9G
3 pnds per G is the minimum for fighter/small aircraft. Normal minimum for lighties is 5 pnds per G. For a yoke in a heavy the minimum is around 11 pnds per G. I think the Boeing will be heavier than this. Otherwise the ham fisted ones amongst us will be breaking wings off.
The Boeing system is going one better to provide some Q feel as well. That is a feel for indicated air speed = half roe v squared.
Pilots will have to do some realigning of their subconscious clues from stick movement as some designers want to have sticks which don't move. Just force input. We should all continue to require some amount of movement to preserve some of those clues..
