The functional enhancement of flight control systems (FCS) show potential benefits for commercial transport aircraft. Furthermore, the consideration of new technologies and more-electric concepts lead to a significant increase of the design space for FCS architectures. The objective of this contribution is to enable the preliminary design of advanced FCS architectures for a given FCS configuration. Based on a comprehensive literature research, the main subsystems are identified and simplified models of the architecture are developed. Additionally, technological constraints as well as design rules for actuator distribution, and power redundancy are defined. The design rules for advanced FCS architectures are derived from the basic design rules of existing FCS architectures of commercial transport aircraft. Finally, the presented method is implemented into a design tool. The resulting tool enables the preliminary design of multifunctional FCS architectures.
