In low speed mode all 4 ailerons operate. However above 190 Kts, in config 0 (Flaps/slats retracted) the otbd ailerons are contolled to zero deflection.
In some failure modes the otbd ailerons will be used up to 300 kts.

I had read several times that on landing, the ailerons on 330/340 deflect UP on both sides to act as spoiler.
However, I have never been able to find any pictures of this. I have only seen landing pictures of spoilers up and ailerons in the drooped position.
Can anyone explain this?

All Airbus aircraft, including the A320 family, have the aileron droop facility. However on the narrow bodies this option is very seldom taken up by the operator. Interesting re-the aileron doubling as a spoiler on landing. I will try to notice it next time I see a landing.

I think all A320/330/340 have droop ailerons with flao extended. I think it's standard. I have never seen a A320 without the aileron droop (UA, US, NW, AW, AC A320....to name a few, all have droop ailerons.
