No. My understanding is that the sidestick commands roll rate all the way until touch down, after which the system blends with ground mode. In pitch, however, there is a direct stick-to-elevator relationship once flare mode engages (50ft RA).

Same obscure roll rate demand than Airbus or more conventional and readable direct control wheel to ailerons command ?

Seems the French unlike Boeing [different type of computers different locating pins at the rear of the mounting tray ]or the Daddy of them all the Trident [if 1 computer didn't agree with the other 2 it was discarded by the system]but as I don't know the Airbus flt system I may be missing a point.but surly it must at least be a Triplex system

EASA has warned operators to ensure that parts are mixed only in accordance with established guidelines from the airframer. "To prevent an uncertified configuration that may result in unexpected operation of the aircraft systems owners and operators should adhere to the interchangeability and mixability rules given in Airbus type certificate holder documentation," it states.

How is it on the 777 ?

As to wrong computer configurations. Sh#t happens all over the world and in any aircraft. The question is, considering this, if a concept that does not allow manual override/intervention, is an adequate one. The incident in question, as the Qantas one, might have been a non issue, if the trying to recover sidestick inputs by the pilots would have had authority.
