Why do you need all the C/Bs at hand? Don't think I've ever pulled more than a dozen of them in flight on an A320 and have no idea what the remaining 95% control or affect, hence would never pull them anyway.. .. .If the sidestick was introduced as a selling point then it is undoubtedly the most expensive selling point in aviation history given the vastly expensive proving process of the sidestick/FBW interface. The sidestick exists because in a full fly-by-wire aircraft with flight envelope protection there's no real need for a control column. Why waste space and cash building a moving control column into an aircraft which won't necessarily mimic what the aircraft is doing? Also a control column wouldn't acurately represent the flight control laws of the aircraft as the Airbus method of control is substantially different from conevntional aircraft. Furthermore by introducing the sidestick you can build commonality across a range of aircraft as the 319 up to the 340 have a broadly similar 'feel' to their handling (or so I'm told), something which you won't get on a 737, 757 and 747.
