I think Sully knew airspeed and attitude was the only thing that was going to matter in his splashdown. He was too good a pilot to depend on automation to help him so he obviously used his flying skills to make sure he had the right speed to flare and zero out his sink rate before ditching. People who love Airbus and think that saved the day are totally wrong. Sully saved the day by being a good pilot. He saved the day, it didn't matter what he was flying.
