Abstract
In a system for positioning the spoilers on the port and starboard wings of an aircraft, a mechanical mixer that incorporates a three-dimensional cam receives pilot-controlled roll (control wheel) and speed-brake inputs and combines them to produce left and right wing spoiler positioning outputs. The cam surfaces of the three-dimensional cam are contoured so that the positioning of the spoilers in reaction to the roll input effects a roll response of the aircraft that is substantially independent of the setting of the speed-brake input.
