Research On Airline Operation Safety Supervision Strategy Based On The SMS

In recent years, the number of flight accidents is going up, such as flying wrong routes,landing on wrong runways, overrunning and overloaded operations. The accident whichhappened in Yichun Airport is an exact example to show those existing problems in airlinesthat includes violations, flaws in the security management and imperfections of operationsupervisions. The Safety Management System, as a new system in China, needs strictersupervisions to make sure its operation and improvement. Besides, in the operation of SMS,airlines also need to improve their measures in the supervising of safety and to enhance thedevelopment of safety management systems.First, this paper analyzes airlines’operation features and their safety conditions. Then, itaims at the changes of relations between airlines’safety management modes, operationalprocesses, preventions and the CAAC’s safety supervisions after the establishment of SMS. Italso studies the SMS evaluation system of the CAAC and the design of the checking quotawhich based on results and processes. Third, it analyzes the existing problems in theoperational supervision system of the CAAC. Reasonable recommendations are raised forimprovement. Fourth, based on the logos of the SMS, the improved supervision system isestablished which pay more attentions to the risk evaluations and preventions. Besides,methods to recognize risks are raised according to the SHEL model. And the improved riskquantitative analysis model is established at the foundation of airlines’existing problems.Analyses about the SMS which are produced in this article will help to improve thesafety supervision theories in Chinese airlines, and provide directions for both the CAAC andairlines in the operation of supervision and safety management.
