Okay, maybe I am slightly misunderstood.
What I am getting at is that maybe it was the LOW wing that was doing all the levelling, and that the high wing was conforming with some form of low drag aileron logic.
Obviously, if you are banking left and give some right yoke to level the wings, you can assume that the right aileron will raise to provide what is required by the yoke.
What I observed on this brand new 783-800 wasn't the case.
What I am asking is does the newer version of the 738 have a form of FBW built in?
