Airspeed felt vs a programmed approach

Large aircraft must have an assist between the controls and the control surfaces due to the forces needed for deflection. Flight controls that are hydraulically actuated require either some programmed limitations or accurate force feedback to the pilot.

This is the difference between fly by wire aircraft and the previous analog loop group. One might suggest the earlier iteration was superior, but the apparent advantages would be mitigated by accuracy, redundancy and predictibility in all but the most extreme environments.

A powered flight control surface that not only does what it is told according to a program, but feeds back into the system the forces that it exerts to maintain the requested position will be the next step in FBW.
