摘 要：FAA states in its NPRM, "Safety Assurance is a set of processes that monitor the organization's performance in meeting its current safety standards and objectives as well as contribute to continuous safety improvement." Safety assurance essentially serves as a checks-and-balances system to ensure that SMS processes and procedures and risk mitigation strategies are having their intended effect (FAA 2010). ICAO states, Assurance can simply be defined as "something that gives confidence." The Safety Risk Management process in the SMS starts with the organization obtaining a good understanding of its operational processes and the environments in which it operates; progresses through hazard identification, safety risk assessment and safety risk mitigation, and culminates in development and implementation of appropriate safety risk controls (ICAO 2009).
