Does this mean the 777X , still has no bank angle limitations ? or was it disabled for this demo flight ?
The current B777 and B787 models have a combination of aural, visual and tactile warnings when banking beyond 35° bank. The tactile warning is in the form of the control wheel input being resisted and, if you let go of the control wheel, will roll the aircraft back to less than 30° of bank. I would guess that the B777X will be the same.
It is a fundamentallly different philosophy from that of Airbus in that Boeing will allow a pilot to fly the aircraft outside of normal operational parameters whereas Airbus prevent a pilot from doing so when in normal control law (if my Airbus understanding is correct).
