Modeling and Analysis of Gate to Gate Flight Process Based on SysML in Commercial Aircraft

The design and development of commercial aircraft is a complex system engineering. At present, operational scenario analysis is gradually used for aircraft function identification and requirement capture. In the analysis process, the time dimension factors of the aircraft in civil aviation operations must be considered, that is, the complete process of aircraft operation must be defined. Guided by the idea of system modeling, this paper presents research on the modeling method of Gate to Gate flight process. The basic elements and hierarchical division of flight process models are constructed. Finally, the paper proposes the method and procedure of establishing Gate to Gate model based on SysML. Based on the previously proposed method and a complete description of commercial aircraft operation process, this paper establishes a summary behaviour model of aircraft's Gate to Gate flight process, covering the preparation before takeoff, push back, taxi out, taxi before takeoff, takeoff roll, takeoff, climb, ocean-based cruise, land-based cruise, descent, approach, final approach, landing, taxi after landing, and taxi to aircraft stand. SysML is used to model the flight process, which includes aircraft itself, ATC, AOC, airport tower and other models. The model is drawn to form Use Case diagrams, Activity diagrams, State Machine diagrams, and Sequence diagrams under each flight phase. The model mainly focuses on the collaborative process between aircraft and various stakeholders, such as the collaborative interaction process between aircraft and ATC, AOC, as well as the collaborative interaction process between aircraft and airport tower during the takeoff and landing phase. This paper provides a method to describe the flight process systematically and graphically. It can also be used as an exploration of function identification and requirements capture methods.
