Providing a foundation for understanding this dynamic and evolving field, Aircraft System Safety explores methods for developing large transport aircraft systems. The book describes safety criteria, including objective targets which can be achieved or monitored and outlines the methods involved in auditing arguments. The author discusses system integration and how best to argue a system’s integrity. He covers the practical aspects of safety, such as integrating safety assessment into a product’s design and life cycle and meeting stakeholder expectations. The book pulls together a wealth of ideas, concepts, tools, and approaches to concisely present the theory of safety in a useful reference guide.
