In the photo below you can clearly see that the nosegear tires are lined up with the runway while the aircraft's rudder is fully deflected....which leads me to think that there's no conection between the cockpit's "tiller wheel" for nosegear steering and the rudder. (unlike small GA airplanes).
My questions to you are....Are the tiller wheel and rudder peddals completely seperated from each other? If so, during the takeoff roll, at what speed does the pilot flying (in this case a 747), switch from his hands to his feet while tracking the centerline?
