A3456 rating
The instrumentation and general layout of the A3456 cockpit looks no different from the A320, A330/A340. The standby instruments are now encompassed in one Smiths instrument rather than several. Another change is that the rudder system on this aircraft is electrical, with a mechanical backup, rather than the purely mechanical system found in the A330/A340. Also there are no two nose wheel steering systems rather than one. With regard to the stick, Airbus uses what it calls a "double notch" system to moderate responses to stick movement while in cruise. In other words, for the same input, roll, pitch, and yaw responses are less while in cruise, and single notch response is used for take-offs and landings to give more control authority for the same input when required, especially in pitch.
