Structural Health Management (SHM) and its related technologies offer the combined benefits of reducing maintenance costs while maintaining or improving structural design performance. SHM implementation for in-service aerospace platforms requires an approach to quantify how each application can provide benefits. A clear understanding from a benefits perspective provides insight to optimize SHM system design. The focus of this paper will be to describe the key aspects of SHM design from a large scale systems integration perspective. This will be accomplished by a brief overview of SHM from a design and integration perspective, followed by a discussion of SHM derived requirements in the context of example applications. Detailed assessments of a particular application often uncover very stringent requirements to meet existing design, operational performance, qualification, and certification criteria.
