Although aviation is among the safest modes of transportation in the world today, accidents still happen. In order to further reduce accidents and improve safety, proactive approaches must be adopted by the aviation community. The International Civil Aviation Organization (ICAO) has mandated that all of its member states implement Safety Management System (SMS) programs in their aviation industries. While some countries (Australia, Canada, members of the European Union, New Zealand) have been engaged in SMS for a few years, it's just now emerging in the United States, and is non-existent in most other countries. This timely and unique book covers the essential points of SMS. The knowledgeable authors go beyond merely defining it; they discuss the quality management underpinnings of SMS, the four pillars, risk management, reliability engineering, SMS implementation, and the scientific rigor that must be designed into proactive safety. This comprehensive work is designed as a textbook for the student of aviation safety, and is an invaluable reference tool for the SMS practitioner in any segment of aviation. The authors introduce a hypothetical airline-oriented safety scenario at the beginning of the book and conclude it at the end, engaging the reader and adding interest to the text. To enhance the practical application of the material, the book also features numerous SMS in Practice commentaries by some of the most respected names in aviation safety.
