Absolutely.
It did performed as designed, but that’s not necessarily the performance the pilot was after for working the flare.

So the aircraft gave Sully the max performance that it could.
... as per its design … but that’s not necessarily the performance the pilot was after for improving the touchdown.

What is a flare Ashling ?


So far from the aircraft being at fault I would say that it perhaps saved them at this stage. Sully pulled full aft stick (in order to flare) close to the stall, had it been a Boeing it may well have stalled with disastrous consequences.
Oh such comment rings a bell, doesn't it ?
Please, would you address it directly to Sully, I think he might put its politically correct discourse aside for the reply …

The key was his decision to start the APU which kept the aircraft in Normal Law. Beyond that the aircraft looked after him and gave him the maximum performance it could while preventing a stall.
The good for starting the APU was to assure full hydraulic + electric but certainly not to maintain Normal Law. Direct Law was all what needed to FLARE properly ... without interference.

Where published figures say otherwise … ?
