Control of pilot control station authority for a dual piloted flight control system
First Claim
1. A system for controlling the priority of control signals received from a pilot control station and a co-pilot control station in a dual piloted aircraft, the control signals being used to provide dual station control signals for controlling aircraft attitude in at least one attitude axis, the pilot control station providing pilot control signals in response to pilot activation of a pilot sidearm controller, the co-pilot station providing co-pilot control signals in response to co-pilot activation of a co-pilot sidearm controller, the system being characterized by:
- priority means responsive to said pilot control signals for providing priority signals, the magnitude of said priority signals being related to the magnitude of said pilot control signals;
attenuator means responsive to said co-pilot control signals for providing attenuation signals, the magnitude of said attenuation signals being related to the magnitude of said co-pilot control signals;
co-pilot priority means responsive to said co-pilot control signals, said priority signals and said attenuation signals for providing modified co-pilot control signals; and
means responsive to said pilot controls signals and said modified co-pilot control signals for providing said dual station control signals.

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.
