Architecture with optimized interfacing for an aircraft hybrid cockpit control panel system

Abstract

A hybrid electronics cockpit control panel system architecture is provided that includes optimized interfacing and partitioning. The architecture includes a digital function block with a digital signal processor and digital communication capabilities. The architecture also includes integrated cockpit control panels that employ a printed circuit board to avoid wire/cable connections for cockpit control panel components beyond the face panel. The architecture provides digital control and communication along a central communication bus that can eliminate the need for dedicated wire connections between the control panel and the electrical components throughout the aircraft, reducing weight and volume. One example aircraft cockpit control panel system includes a control signal processor that receives electrical control signals from pilot operating devices on the control panel and transforms them into digital status signals for communication on a communication bus. In another example aircraft cockpit control panel system, the control signal processor transforms the electrical control signals into digital control signals that are communicated to aircraft components. In another example aircraft cockpit control panel system, signals from a first control signal processor are passed through at least a second control signal processor to provide a redundant circuit path.
