Safety Management Systems in Aviation presents the quality management underpinnings of SMS. The four components that must be designed into proactive safety are: Safety Policy, Safety Risk Management, Safety Assurance, and Safety Promotion. Including coverage on the cultures of regulatory organizations and expanded coverage on culture assessment, the book considers the nexus between cultural maturity and safety management performance. This third edition features new coverage of international requirements and implications for harmonization across international boundaries. In addition, the book includes new chapters and sections, examples, a hypothetical airline-oriented safety scenario, and case studies to enhance and reinforce student understanding. The book is intended for undergraduate and graduate aviation students taking Safety Management and Aviation Safety courses. It also functions as a valuable reference tool for SMS practitioners.
