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.

Aircraft designed for transporting one or two persons, much like a small personal car but flying in the air based on Bernoulli Principle and Newton's laws, are called Personal Aerial Vehicles (PAVs). Due to high PAV traffic densities and the high velocities at which PAVs fly, manual piloting of PAVs is seldom recommended. Hence, PAVs are equipped with an inbuilt Autonomous Navigation and Control System (ANCS), which frees the rider from piloting skills. Machine learning (ML)-based approaches that require datasets used during training phases can be used for implementing the software of such ANCS. The development of simulation-driven systems for ANCS offers many advantages, particularly reducing the systems' developmental costs and infrastructure needs. In this article, we report on the development of a synthetic visual dataset that enables ML-based implementation of ANCS. The state-of-the-art simulator AirSim is used to generate this dataset. Additionally, to make the synthetic data more realistic, several augmenting technologies such as Unreal Engine (3D graphics gaming), Blender animator, PX4-Autopilot SITL (Software in the loop) software, QGroundControl Autopilot App, and ROS (robot operating system) middleware suite are utilized. We also discuss the applicability of this dataset in realizing the ANCS module for PAVs.
