Autothrottle system for aircraft interfacing with fadec system
A recently granted patent (Publication Number: US11975861B2) discloses a system for controlling the autothrottle of an aircraft equipped with a full-authority digital engine control (FADEC) system. The system includes an autothrottle controller with processing circuitry, memory, and input/output facilities, capable of receiving sensed power-control input (PCL) position signaling and outputting automated power command signaling. The autothrottle controller works in conjunction with a FADEC interface to select between the sensed PCL position signaling and automated power command signaling to be coupled to the command input. The automated power command signaling is synthesized to mimic the electrical characteristics of the sensed PCL position signaling, ensuring recognition by the FADEC system.
Furthermore, the system ensures safe failure by defaulting to selecting the sensed PCL position signaling when not engaged for autothrottle control. The autothrottle controller and FADEC interface are designed to only select automated power command signaling when fully functional and engaged. The method involves executing an autothrottle control program, determining a control-target setting, receiving sensed PCL position signaling, and outputting automated power command signaling based on the control-target setting. The system also includes features such as learning electrical characteristics of the sensed PCL position signaling during configuration and transitioning out of the engaged state in response to a change in manual throttle setting based on the sensed PCL position signaling.
