Hm I tried a landing two days ago in Hamburg Kiel with the Fenix, and it behaved just like a gooood Airbus should do. (Gooood Airbus she will get the finest Kerosene treatment and the most expemsive turbine oil later!)
Here is a screenshot from the final approach:
(That I have forgotten to press the APPR approach button on the autopilot to start the descent is a different story, and that I run out of fuel while doing the second approach because the strong headwind burned too much fuel during the flight, also… 
)
But the airspeed was always fine during the strong winds while autothrust was on.
