In avionics domain, currently most engineering efforts and costs come from integration, verification and validation activities. Each error found on requirements during product verification or validation requires a full engineering cycle to manage the change: impact analysis, design, realization, integration, verification and validation again. Hence, ensuring early and continuous validation of requirements in the engineering life cycle, becomes more and more crucial. In this paper, a Model-Based Systems Engineering (MBSE) approach is proposed. The proposed approach relies on SysML models and is composed of modelling tasks to capture requirements and to structure functional interfaces and functions. This approach has been applied in the frame of SAE ARP4754A aerospace recommended practices.
