That thingy that shows sidestick position on PFD (and to me it looks more like WW2 Luftwaffe cross than Maltese one) is certainly not an useful tool as additional feedback for control inputs by the collegue once airborne because... it disappears as soon as weight is not on wheels. A lot of top AB instructors certainly know their FCOMs well.
Very good story, CONFiture. Now let's suppose the same too-little-nose-up-trim mistake has happened on aircraft with classic flight controls:
You call V1
You call Vr
You don't see the usual nose movement, but as vigilant PM you see that capt has pulled just the right amount of yoke so chances are you probably do nothing, believing everything will be fine. I mean, you did nothing when you didn't know what the captain control inputs were, why would you do anything now when you see that they're correct?
Captains pulls a little more and as veesquared starts to bite, nose pitches up far too quickly
thanks God, PF is as fast to stop that high rate rotation ...
So what's the relevance of miscalculated CofG to FBW controls?
