The only time a commercial pilot hand flies the plane is for the take off and landing, about 30 sec on take off and 5 min or so on the landing. Autopilot flies the plane the rest of the time, when the commercial airliner turns at altitute the pilot is not turning the yoke with his hands, he sets the heading bug on the compass (like setting a watch) and the auto pilot follows it. Autopilot is the best invention ever for hangovers.
