1. Do Airbus flight controls use artificial feel units?
2. If they do, how would it behave in a scenario with unusual airspeed readings, like AF 447 had? Because an AFU needs airspeed input right?
3. Is this of any significance?
Like dozy already answered modern airbus don't have artificial feel, A300/310 had.
IMHO this accident wolud NOT have happened with artificial feel.
