The aircraft scenario modeling and requirement capture method are studied under the framework of Department of Defense Architecture Framework( DoDAF) based on Model Based System Engineering( MBSE). Firstly,the description method based on DoDAF,basic elements and the model levels of aircraft operational scenario are presented successively. Secondly,the aircraft requirement capture process and analysis steps based on scenario are determined. The operational requirement could be captured by the interaction between aircraft and various stakeholders in the different operational scenarios. Then,the scenario model of a certain civil aircraft including flight phase level,task cell level and behavior unit level are constructed based on DoDAF. The process of operational requirement capture based on above model is elaborated in detail. At last,the research results of this paper can be applied to capture the operational requirement of aircraft. More importantly,the results can also be utilized to connect the market need with development process of aircraft. The traceability between market need and development requirement can be identified effectively.
