As the complexity of modern aircraft systems continues to grow, traditional development methods are be-coming increasingly challenging in terms of management and maintenance. Model-Based Systems Engineer-ing (MBSE) provides a comprehensive and integrated approach to systems engineering, enhancing communi-cation, collaboration, and traceability throughout the development process. We first evaluate the development process of aviation flight control systems in current systems engineering practices, elucidating the drawbacks of traditional development approaches and the core principles and advantages of MBSE, as well as common-ly used tools and methods in its implementation. We then demonstrate how MBSE uses models to support the specification, design, analysis, verification, and validation of complex systems during the development of flight control systems. Finally, we outline future research directions, including the development of advanced MBSE tools and methods, the prospects for combining MBSE with agile development, and the need for im-proved interoperability and standardization in MBSE practice. This paper provides resources and insights for aviation industry professionals, systems engineers, and researchers interested in leveraging MBSE methodol-ogies and tools to improve the design, development, and performance of flight control systems.
