摘要
随着航空技术的突破性进展,国际民航组织提出了基于性能的通信导航监视(CNS)系统,其由所需通信性能(RCP)、所需导航性能(RNP)和所需监视性能(RSP)组成。同时,缩小间隔标准可以有效地缓解流量增长和减少延误,因此基于CNS性能的垂直间隔碰撞风险评估具有重要意义。建立了CNS性能条件下的定位误差模型,推导出了垂直重叠率和侧向重叠概率的计算公式,应用于Reich碰撞风险模型。通过算例对垂直间隔碰撞风险进行了安全评估计算,结果表明所给出的基于CNS性能的垂直间隔碰撞风险评估模型是可行的。
With the breakthrough of aviation technology, international civil aviation organization put forward the communication, navigation and surveillance（CNS） system based on performances. It is composed of required com munication performance （RCP）, required navigation performance （RNP） and required surveillance perfor mance（RSP）. Meanwhile,the separation standard is required to be reduced in order to enhance airspace capacity and decrease delays. Therefore,the assessment of collision risk of vertical separation based on CNS performances has the vital significance. A position error model was established under CNS performances circumstances and a computation formula of vertical overlap probability and lateral overlap probability were deduced that were applied to collision risk model of Reich. Assessment of collision risk of vertical separation was conducted through an example. Computation result shows that the assessment model of collision risk of vertical separation based on CNS performances is feasible.
