the airplane while taxiing. This usually takes the form of a small steering wheel or lever in the cockpit, often one for the pilot and one for the co-pilot. However, they differ from the tiller on a ship. Rather than move the rudder, the tiller on an airplane steers by turning the nose wheel, and the tiller is moved in the direction of the turn, rather than opposite the turn as on a ship.
