Requirement paramerisation of flap actuation system: Product life-cycle management processes & tools

Flap actuation systems (FAS) have numerous operational states, modes and environmental constraints, which translate to thousands of requirements associated with them. FAS must be analyzed and tested to determine compliance with requirements in any operating conditions. In this paper, examples of parametrized requirements for centrally driven FAS are presented and the advantages brought by a requirement parametrization process in the systems engineering life- cycle discussed, from requirements elicitation to requirements validation and verification. The challenges of robust re-use and customization of components within legacy systems to drive cost reduction is significant as often legacy products were not developed within a model base framework. The requirements prioritization process provides a low cost, high impact example of alternative to ensure integrity and full traceability of requirements without the need to implement complex simulation platforms.
