With the advancement of computer technology, Virtual Flight Testing (VFT) methods have gradually integrated into the early validation activities of the civil aircraft product Iifecycle, becoming a mainstream approach in product development. Addressing issues such as inconsistent understanding in traditional document-based methods and weak correlation between requirements and validation activities, this paper focuses on the civil aircraft Fly-by-Wire (FBW) Flight Control System and proposes a top-level modeling and integrated simulation method for airworthiness validation in virtual flight testing. Firstly, starting from the descriptions in airworthiness regulations, we construct activity models for flight testing verification oriented towards compliance and quantitative constraint models. Secondly, we clarify the static structure, dynamic activities, and parameter constraint relationships within the system, establishing the top-level architecture model of the system. Subsequently, we create low-level simulation models for each unit within the system and achieve the correlation between the top-level and low-level models, thereby constructing a virtual integrated simulation environment based on SysML & Simulink. Finally, with the support of the virtual integrated simulation environment, we achieve real-time virtual simulation based on flight testing verification activities and automatic validation of airworthiness compliance. Experimental results demonstrate the system's compliance with the example airworthiness regulations, validating the feasibility of the proposed method.
