Flight Safety,
That was exactly my point when I first met this system.
However I must admit that although there's no correlation between stick input and attitude, the system works very well in telling you the percentage of flight control input at a time when they produce no effect on attitude i.e, ground roll. It's just placed in the right place.
As in many Airbus designs it may sound weird when read but you've got to use it to really appreciate its functionality.
This is no concern whatsoever to any experienced Airbus drivers and I'm pretty sure it was not contributory to this incident.
