Qualitative Analysis Method of Civil Aviation Safety Information Sources

Abstract

There are many research models on causes of accident. Professor Edwards's SHEL (Software Hardware Environment and Liveware) model was presented in 1972, Professor James Reason from Manchester University applied organization, and management considerations into the cause analysis of accident and created Reason model. “Research Institute of Civil Aviation Safety” of civil aviation university of China created a new analysis technique in 1996 based on Reason model which was named “Elementary Events Analysis Method”, Wiegmann and Shappell developed the Human Factors Analysis and Classification System (HFACS) model, Threat and Error Management (TEM) analysis technique which not only focuses on a single event but also understands the multi-events system model. Confidential reporting or mandatory reporting is the main source of civil aviation safety information. Using SHEL Model, Reason Model, Elementary Events Analysis, HFACS Model, TEM analysis technique to analyze the selected representative confidential reporting or mandatory reporting respectively, comprehensively compare these qualitative analysis models and techniques, we can clearly know the advantages and disadvantages of each method, help the researcher find the most suitable method. TEM analysis technique is simple and easy to operate. When faced with a large number of accident / incident cases, TEM analysis technique will help complete the task efficiently. If one wants to get a specific analysis of accident / incident, HFACS model is suggested.
