(7) Analysis of Factor of Bird-Strike Risk at Narita International Airport

摘要

When the state, local governments or airport administrators implement the effective countermeasures for bird strike, it is important to understand the factors in determining the risk of bird-strike to be managed. In this study, we developed bird strike risk model using a generalized linear model were analyzed and attempted to identify the factors to affect the bird strike risk at Narita International Airport. As a result, the period of month, the time of day, precipitation, lane location and the number of birds were affective factors regarding the possibility of a bird strike event. Especially, the bird-strike risk was tend to be high between 06:00 and 9:00 in July. An expected finding was that the risk of bird strikes increased during days with no precipitation. Furthermore, it was found that the risk of bird strikes significantly increased by the number of the bird in a bird species, such as swallow.
