An aircraft that has no trim?? is there any such thing??? Airbuses DO have trim only not in the same sense as Boeings etc do. I believe it's automatic trim in the A320/A330/A340-i.e you select the attitude you want with the sidestick and the trim wheel moves automatically to trim it to that position, i don't think the pilots themselves touch the trim wheel though. Anyone feel free to correct me if i'm wrong
