Flight Control System Modeling with SysML to Support Validation, Qualification and Certification

:The introduction of new technologies to build ‘More Electric Aircraft’ induces new challenges for both the design and safety analysis of new aircraft. A model-based approach is needed for both design and validation processes in order to manage the complexity and validate the conformance to safety requirements. In this paper, a SysML-based approach merging MBSE and MBSA is presented. This approach is applied to a Flight Control System (FCS) both for the design and the validation processes. A parallel is made to compare the models used in each of these processes. This comparison led to suggestions of improvements both for the design and verification and validation approaches.
