摘要
保障尾流安全间隔是航空安全领域的难题,为了优化分析航空器的碰撞风险,依据国内管制的要求,采用两种碰撞风险模型——REICH模型和EVENT模型来研究碰撞风险,并侧重于REICH模型的算法,将实际中的参数带入REICH模型和EVENT模型中进行运算,把两种模型的运算结果进行对比得出:REICH模型和EVENT模型都能精确分析航空器安全间隔的参数重要性,EVENT模型运算起来更为方便而REICH模型中的参数相对冗杂.两种模型各有优缺点,需要根据实际空域情况采用合适的模型.
Ensuring wake turbulence safety separation is a difficult problem in the field of aviation safety.In order to optimize the analysis of aircraft collision risk,two kinds of collision risk models,REICH model and EVENT model,are used to study the collision risk according to the requirements of domestic control.The algorithm of REICH model is emphasized,and the actual parameters are brought into REICH model and EVENT model.Comparing the results of the two models,it is concluded that both REICH model and EVENT model can accurately analyze the parametric importance of aircraft safety separation,and the EVENT model is more convenient to operate while the parameters of REICH model are relatively complicated.The two models have their own merits and demerits.Different models need to be adopted according to the actual situation in airspace.
