摘要
为改进精密进近航段内障碍物评价方法,提出基于碰撞风险模型（CRM）的障碍物椭圆评价面的构建方法。首先,利用CRM计算精密进近航段各位置处碰撞风险概率,椭圆拟合概率为1×10-7的点,构建椭圆评价面;然后,以某典型机场为例,分别使用障碍物椭圆评价面、障碍物评价面（OAS）评价典型障碍物,并对比其评价结果;最后,利用CRM验证障碍物椭圆评价面的可靠性。结果表明：OAS的评价结果较保守,运用新构建的障碍物评价椭圆面能在满足安全运行的前提下,有效提升机场精密进近航段空域利用率。
In order to improve the obstacle evaluation method in the precision approach segment,a CRM based ellipse evaluation method was proposed. Firstly,the probability of collision risk at each position of the precision approach segment was calculated by CRM,the ellipse fitting dots which risk probability is equal to 1×10-7 were chosen,and the elliptical evaluation surface was constructed; Then,taking a typical airport as an example,the obstacles ellipse evaluation surface and obstacle assessment surface（ OAS） was used to evaluate typical obstacles,and the evaluation results were compared. Finally,CRM was used to verify the reliability of the obstacle ellipse evaluation surface. The results showed that the evaluation results of OAS were conservative. Using the newly constructed obstacles to evaluate the elliptical surface could effectively improve the airspace utilization rate of the airport precision approach segment under the premise of meeting the safe operation.
