Research on Identification of Risk Factors in Civil Airports

In order to strengthen the risk management of civil airport operations, identification of risk factors at civil airports is the most critical step. In order to analyze the risk factors of the airport comprehensively, risk factors were identified from both active and passive aspects in this paper. That is, risk identification was performed before and after the event. From active aspects, the airport risk index system was established based on the SHEL model, including 12 indices. And the corresponding airport risk based on the index system established was analyzed. From passive aspects, the typical unsafe events occurring in the past 2 years were analyzed based on the REASON model. And the identified airport risks from passive aspects were incorporated into the corresponding module risk of the SHEL model to get the final risk. Finally, taking an airport as an example, the above methods were used to identify the 20 risk factors currently existing in the airport, which included 2 liveware-liveware factors, 10 liveware-software factors, 4 liveware-hardware factors, 4 liveware-environment factors. According to the identified risk factors, the corresponding preventive measures were proposed for reference by airports and airlines to improve the risk management level.
