摘　　要：主要对平行航路中基于CNS定位误差的飞行间隔安全评估问题进行了研究。首先分析了CNS定位误差对飞机碰撞风险的影响。其次运用概率论方法得到了CNS定位误差下飞机纵向、侧向和垂直三个方向上的碰撞风险计算模型,并根据模型利用牛顿迭代算法,通过给定某一方向安全目标水平计算CNS定位误差下相应的安全间隔。最后对平行航路三个方向的飞行间隔进行了评估计算,将结果与实际相比较,表明该模型可行。The Safe Separation based on CNS position error on the parallel route is studied in this paper. First, the effect of CNS positioning error on the aircraft collision risk is analyzed. Then the along- track, across- track and vertical- track computing safe separation models under given CNS position error are gained by utilizing Probability Theory. Then the arithmetic of models is established based on the features of the models. Finally, an example is analyzed, compare the result with the target level of safety shows that the models are feasible.
