Thanks for the update, and sorry for my sh.. I went nuts before. Of course it was the AI trim what caused the wild up and downs. Just made a simple 600nm testflight with the update, even with another flightplan (5000nm away :D) just to see if the A350 flies for me, most in simple AP use. And here we go, it works. Just got a alarm when I switched of the AP at landing which didn't stop, could not find to set it off. After a while it ended. And the reverser did not close at the engines after setting idle, don't know, I switched on the parking brake inbetween, then put on some taxti-thrust and it closed the reversers.
