Can you turn a large airliner using only rudder input?
Yes you can, and this is the backup mode for turning the A320 when the Fly By Wire has failed. It is not very comfortable though:


Changing direction using only the rudder creates sideways acceleration, not good for passengers with drinks in front of them
Since the rudder is located above the center of gravity, the aircraft leans the wrong way when rudder only is used, amplifying the sideways acceleration. A ship has the rudder below the center of buoyancy and leans into the turn when rudder is deflected.
