As an important approach and tool in model-based system engineering, functional modeling can help engineers to clarify customer requirements, establish functional architecture and generate solution concepts, and it has a wide range of application prospects in the aviation field. However, most existing functional modeling methods do not fully consider how to formalize the generated functional architecture solutions and cannot effectively represent functional logic, especially involved in complex interactions among the system, the user, and the operation environment. Therefore, this paper proposes a scenario-based functional modeling approach for civil aircraft systems. This method combines the concept of scenario in software engineering, builds the aircraft operation scenario model, further establishes the requirement, structure, behavior, and parameter model, and elaborates the functional interaction logic among the aircraft systems. Taking the primary flight control system in the aircraft deceleration on the ground scenario as an example, the functional model of the control spoiler extending and retracting is established and simulated, which demonstrates that the functional modeling approach is applicable to the functional design of civil aircraft system.
