Exploring SysML v2 for Model-Based Engineering of Safety-Critical Avionics Systems

For complex and safety-critical avionics systems, distributed developments are unavoidable. To coordinate the fragmented development process, a seamless information exchange is necessary. A promising paradigm to coordinate the development activities is Model-Based Systems Engineering (MBSE). However, exchanging information with current MBSE practices still presents interoperability challenges. The second version of the Systems Modeling Language (SysML v2) introduces potential solutions to these challenges. A key feature is the standardized Application Programming Interface (API), presenting an opportunity for server-based data exchanges. Since it is not yet explored how the SysML v2 features can be utilized for the development of avionics systems, this paper provides an overview. Therefore, a SysML v2 avionics application concept is outlined, exercised, and discussed. Overall, SysML v2 shows potential to complement model-based avionics practices through novel features and the standardized API. Still, domain-specific adjustments are necessary to apply the general-purpose language in the avionics context.
