The B737 has an autopilot mode called CWS, when you operate the autopilot through the yoke. The A320 flight control system is operated through the sidestick, but basically it is the same as 737 CWS. You cannot turn the autopilot off - the sidestick is connected to computers, not control surfaces and there is no manual reversion. During conversion, everyone practises landing the aircraft using thrust levers for pitch and rudder trim for yaw. It works nicely in the simulator. Anyone who has "flown" the A320 outside the design envelope will know that the aircraft will then respond in a random fashion to control inputs. Landing in gusty conditions it is not unusual to run out of elevator authority. In really bad conditions aileron authority will also go. The A320 is a good first attempt at fbw, nothing more.
