摘　　要：为了有效地确定平行航路安全间隔和评估碰撞风险,分析了平行航路侧向碰撞风险影响因素,在Reich模型的基础上建立了飞机在CNS性能环境下的定位误差模型,推导出基于CNS性能的平行航路侧向重叠概率的计算公式。通过算例对平行航路侧向碰撞风险进行了安全评估计算。结果表明所给定的CNS性能在平行航路飞行环境下是安全的,因此计算方法是可行的。In order to confirm the safe separation of parallel routes and evaluate collision risk effectively, lateral collision risk influence factors of parallel routes were analyzed. A position error model was established under CNS performances circumstances and a computation formula of lateral overlap probability of parallel routes based on CNS performances was deduced. Assessment of lateral collision risk was conducted through an example. Computation result shows that the flight environment with CNS performances is safe, so the model is feasible.
