I've often thought that some force feedback is the answer to Airbus' problem.
If the stick position is motored to show the summed flight surface movements, it would be easy to provide the means to show the uncoupling in jammed control conditions by making the individual sticks show the movement in that side only. Who needs a load of ECAM messages when one moves and the other doesn't!
Also, if a pressure sensor is used on the stick neck, as in some fighters, you push the stick to move it, but the force is sensed and fed to the FBW system. The actual movement is a feedback to you. Thus any interference of Alpha Floor, or similar can be felt directly as the stick not responding in a natural way. Also if they moved the bloody throttles as well, you'd actually be able to FEEL the plane flying for you and be in the loop if you disconnect on a windy day or whatever.
I suspect it's this lack of feedback to provide feel is why many like me really don't want to fly Airbus products anytime soon.....
