Risk Assessment of Separation Between Runway and Taxiway Not Meeting Standard During Take-off

In view of the fact that the separation between runway and taxiway of the flying area can't meet the standard separation and the risk of aircraft operation, this paper analyses factors causing aircraft veer off the ground in taking off and uses entropy of information to select 15 factors in the 25 factors combines with the multiple Logistic regression method to set up the accident frequency deviation model. On this basis, combining with accident event model which is based on the history data of the plane veer off the runway, the risk model of the taking off stage is established when separation does not meet the standard requirements of the running slip distance. By running the risk model, this article takes the airport as an example to analyse the collision risk of sliding on the ground in taking off under the existing conditions and put forward the operation method of determining the separation between runway and taxiway and the operation constraints when the separation can't meet the standards, providing a theoretical basis for determining runway operation conditions and designing the separation between runway and taxiway.
