| 摘 要： | 为了研究通信导航监视(communicatio,navigation and surveillance,CNS)下的定位误差和纵向碰撞风险及其影响因素,在Reich模型的基础上,分析通信、导航和监视误差,推导出平行航路纵向重叠概率的计算公式.据此建立了基于CNS性能的平行航路纵向碰撞风险评估模型.算例表明,所给定的平行航路在RCP400、RNP10和RSP20条件下,碰撞风险为3.0×10~(-10),达到国际民航组织安全目标水平的要求.评估模型是可行的.

| Abstract: | In order to study the positioning errors and longitudinal collision risk of flights and their influence factors under communication, navigation and surveillance (CNS), the CNS errors were analyzed and a formula for calculating the longitudinal overlap probability on parallel routes was derived based on Reich model. Hereby, a CNS-based assessment model of longitudinal collision risk on parallel routes was established. The result of a numerical example shows that the collision risk on the given parallel routes in RCP400, RNP10 and RSP20 conditions is 3.0 × 10~(-10), satisfying the safety target level specified by the International Civil Aviation Organization. Therefore, the assessment model is feasible. |
