[Objective]This paper tries to assess the terrorism risks facing civil aviation industry quantitatively and objectively. [Methods] We proposed a risk assessment model based on K-means clustering, and then examined it with the data of terrorist attacks from 1992 to 2015. We calculated the risk of different types of attacks and their targets objectively. [Results] The risk of aircraft bombing, armed assault against the airport and airline staff were the highest, the risk of hijacking, bombing/explosion aginst the airport or airline staff were at medium level, and the risk of other attacks were relatively low. We used this method to predict the risk of terrorist attacks against the civil aviation in 2016, and the prediction accuracy was up to 92.3%. [Limitations] The proposed method for risk assessment is only suitable for processing numerical data. [Conclusions] The K-means clustering method can assess risk based on statistical data without human intervention, which could be applied to similar studies.
