There was a significant difference in B737 family & B767 on nasty days. The control column was much calmer in the larger a/c. B733 was stirring the pot; B767 more gentle inputs. How is it from A319 - A330/340/even 380
The 767 has excellent control authority (notably in roll), and rarely needs coarse inputs to keep it on the straight and narrow. For me, the problem with the A330/340 (can't comment on the other Buses) is the amount of lag in the flight control system. You simply don't have the sense of a direct and immediate connection with the controls. Again, this is most obvious in roll. When everything's smooth there's no problem, but it makes things a bit busy and unpleasant in the rough stuff. I can live with the non-moving thrust levers, but the autothrust system is slow to react and then applies excessively large inputs. This means it does things for which a human pilot would deserve a smack over the knuckles with a ruler (e.g. idle thrust at 150' due to a few excess knots).
