A primary flight control system is presented which resulted from Boeing's large airplane research from the mid-to-late 1990's. The system is a derivative of the 777 flight control system and is simplified to remove expensive interfaces and to minimize wiring for a large aircraft. The new architecture is shown and contrasted with the existing 777 flight controls. Estimated costs show when remote electronics on the actuators will reduce cost. A novel two-wire power and data bus is shown for communication to the actuators.
