Abstract
In a dual station sidearm control system, a pilot control station provides pilot control signals in response to pilot activation of a pilot sidearm controller (210) and a co-pilot station provides co-pilot control signals in response to co-pilot activation of a co-pilot sidearm controller (211). The pilot control signals and the co-pilot control signals are combined (220) to provide dual station control signals for controlling aircraft attitude in the yaw, pitch, roll and lift attitude axes. A priority detector function (222) is responsive to pilot control signals in one of the attitude axes for reducing the priority of co-pilot control signals with respect to pilot control signals in the one attitude axis as the magnitude of pilot control signals increases in the one attitude axis. An attenuator function (225) is responsive to co-pilot control signals in the one attitude axis for attenuating the priority mismatch between pilot control signals and co-pilot control signals as the magnitude of co-pilot control signals increases in the one attitude axis.
