As I recall (Slightly clouded by time) The rudder movement was progressively reduced at speeds above 160kts thrugh the Q Feel system and also when the bomb doors were open to prohibit excessive yaw. Therefore on the ground the rudder limiter should be fully withdrawn with the indicator (to the right of the throttle quadrant) showing "out" or "bomb doors open - out" depending on the bomb doors being open or closed. With the bomb doors closed full rudder should be available on the ground.
