Is it possible to turn a large jet like the Boeing 747, Airbus A380 or other airliner using only the rudder, i.e. without using the ailerons on the wings? Will it take longer to turn to a new heading? I find the tilting when ailerons (wing flaps) are involved is uncomfortable.

In a well-executed (aileron) turn you should hardly notice anything. $\endgroup$ – DaG May 29 '17 at 9:46

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.
