At 13 mile final on the ILS to 22L at Helsinki, full flap was deployed once the ac slowed beyond the reqd speed. At a similar time a engaged APP as LOC was established. As I did this the auto-throttle disconnected (which I didn't notice as a VFE warning also came on), the aircraft lost speed and almost entered stall until the aircraft corrected itself. Speed indications stuck on the PFD at 120knts despite the ac accelarating as TOGA selected. Stby inst indicated increasing speed. Autopilot re-engaged (by me) then entered a side to side rocking motion before I decided to eject (lol). I've only had the 350 for a week and think it's good but clearly some issues still to sort.
