Airplane system design for reliability and quality

Two important subjects in the airplane & system development lifecycle are addressed. The first subject is the allocation of reliability and maintainability (R&M) requirements to components from airplane and system effectiveness metrics. The second is the determination of requirements for the quality sampling plan for components, a key process in the quality system. Systematic methodology for deriving R&M requirements for components given multiple airplane effectiveness metrics are presented. Given component reliability requirements a method is presented to derive the quality level needed for component manufacturing to ensure the reliability requirements are realized in the field. Together the methodologies presented here enable an integrated and rigorous airplane and system development process following best system engineering practice.
