I have no pretension or even desire here to modify the way the control law is programmed.
It can be a great idea to wish to protect an aircraft from stalling, but on that particular case on the Hudson, even if the speed was below Vref, it was still possible for Sully to reduce the vertical speed at touchdown and obtain the Airbus recommended attitude for ditching ... if only the elevators were to follow the pilot request.
Sully would have been better served with a direct law with full and known control on his elevators.
