The aircraft electric taxiing system is a key technology in the development of green aviation, which changes the traditional aircraft taxi technology and improves the reliability and maintainability of the aircraft system. It is the development trend of the future aircraft ground control systems. Model-based systems engineering (MBSE) applies a graphical and modeling method applied to the system design, following the model based systems engineering approach to design aircraft electric taxi systems. This paper presents a method to confirm the coverage and correctness of aircraft electric taxiing system requirements using a model. The system requirements confirm the coverage of the stakeholder requirements, and a behavior model based on MATLAB/Simulink is used to confirm the accuracy of system requirements. Finally, the future development of aircraft system and the comprehensive application of model-based system engineering are prospected.
