| 摘 要： | 着重对区域导航平行航路的侧向重叠概率的计算进行了研究。首先,通过数据统计,分析侧向重叠概率在平行航路安全性评估中的重要性;其次,利用双指数分布和分离的双指数分布对区域导航技术下的平行航路侧向重叠概率进行了计算;最后,通过仿真比较来确定最适合区域导航下的平行航路侧向重叠概率的计算方法。结果表明,用分离的双指数分布描述大偏航密度函数所得的侧向重叠概率更接近于实际情况。

| Abstract: | The calculation of lateral overlap probability of RNAV parallel routes is focused on. Firstly, the importance on lateral overlap probability of safety assessment of RNAV parallel routes is analyzed. Then, the lateral overlap probability of RNAV parallel routes is studied through double exponential distribution and separated double exponential distribution respectively. Finally, the different methods of probability of lateral overlap are compared to find the best method of lateral overlap probability of RNAV parallel routes. The result shows that the non- core distribution density modeled by a ＂separated double exponential＂ distribution is more realistic. |
