The present invention provides a landing gear force and moment distributor system (20) for an aircraft having a landing gear including a pair of bogies arranged symmetrically about the longitudinal axis, each bogie having an actuator arranged to brake and/or drive one or more wheels. The force distribution system comprises a distribution module arranged to: receive an input demand including a longitudinal force input demand corresponding to a desired braking or driving force along the longitudinal axis for the landing gear and a moment input demand corresponding to a desired moment about the vertical axis for the landing gear; and to use the received input demand to calculate an output command comprising, for each bogie, a longitudinal force output command corresponding to a braking or driving force along the longitudinal axis to be applied to said bogie to achieve the longitudinal force input demand, and a moment output command corresponding to a braking or driving force along the longitudinal axis to be applied to said bogie to achieve the moment input demand.
