Kathryn, The purpose of a two system (dual) rudder is the same as the ailerons (inboard and outboard). During slow speeds (takeoffs and landings), both systems (upper/lower rudders) work together for effective control, while at higher speeds (cruise) the need for large control surface movement is lessened.
