Risk Evaluation for Bird Strike in Zhengzhou Airfield Based on the Danger Level to Aircraft

Abstract:

Bird environment in different airfield is quite different, which results the causes of bird strike have significant differences. It should be based on the actual bird environment information and analysis results in different airfield, to develop practical prevention measures for bird strike. Through the investigations of bird situations in Zhengzhou airfield, combining with regularity and characteristics of the previous bird strike events, the five factors evaluation model of bird strike risk is initially built. Evaluation system for bird risk is built based on the principle of entropy method empowered. Based on the evaluation model of bird strike risk, the risk values and integrated risk values (IRV) of different bird species can be calculated in Zhengzhou airfield. The airfield birds are classified with the difference of bird strike risk according to the IRV. Specifically preventive proposals and measures are put forward based on bird strike risk classification for the different bird species. The results show that bird species of highest risk account for more than 20%, and higher risk more than 26%. Countermeasures of bird strike prevention are proposed with the results of risk classification. First it should be taken preventive measures, which focus on 7 bird species of IRV≥0.4. Second it should be paid attention to the prevention of 9 bird species on 0.3≤IRV<0.4.
