On a related theme....
The 744 maintenance manual describes the override mechanism connecting the autopilot rollout actuators to the rudder system... It says that the autopilot can be overridden by manual input to the rudder pedals at any time (without disengaging the autopilot).
This was tried in the sim recently by a 747 pilot... and, oddly, the aircraft tracked straight as an arrow. This contradiction was noted by another 744 pilot who tried it in real life during a (ferry) flight.. at 130 and 80kts. The (real) aircraft again tracked straight down the centerline.
Perhaps a possible explanation for this contradiction could be what Bel Arg says... The rudder pedal steering has about the same effectiveness as a piece of wet Kleenex tissue
