Abstract: A method of providing fin commands for a vehicle is shown to include the steps of calculating a pitch-to-roll command ratio equal to an absolute value of a pitch command divided by a roll command and calculating a yaw-to-roll command ratio equal to an absolute value of a yaw command divided by the roll command, differencing the yaw-to-roll command ratio with the pitch-to-roll command ratio to provide a difference value, and apportioning the roll command to at least one of a plurality of control fins in relation to the value of said difference value. With this arrangement, a method of apportioning a roll command to a plurality of control surfaces wherein the maximum deflection required by the control surfaces is minimized by apportioning more roll to the plane having the smaller maneuver.
