近距平行跑道配对进近方式的安全区域

为了提高我国近距平行跑道的运行效率,对配对进近方式的安全区域进行研究.根据配对过程中快机和慢机的相对运动关系和速度特征,将配对进近分为快机不可超越慢机和快机超越慢机两种方式.将慢机作为参考量,分析快机的相对运动状态,定性地给出两种配对方式的安全区域范围.在此基础上,考虑慢机错误地闯入快机航向道,建立防撞安全边界计算模型;考虑配对前机在最大不利侧风影响下的尾流对后机的影响,建立尾流安全边界模型.利用虹桥机场的相关数据,采用C类航空器B737-800,D类航空器B747-400作为配对进近的两架飞机,对模型进行验证.结果表明:该方法可以实现实时定量地计算两种配对方式下的安全区域范围.

Research on the Safe Zones for Paired Approaches to Closely Spaced Parallel Runways

In order to improve the operating efficiency of closely spaced parallel runways, safe zones of paired approaches is analyzed. Combined with the relative motion relationship and speed characteristics of paired aircraft, paired approaches is divided into fast aircraft can not pass the slow aircraft pairing mode and fast aircraft beyond the slow aircraft pairing mode. Regarding the slow aircraft as the reference volume, the relative motion state of the fast is analyzed, and the safe area of the two pairing modes is given qualitatively. And then, taking account blunder, the model of collision-safety boundary is established. Meanwhile, considering the effect of the lead aircraft to the trailing because of side wind, the model of collision safety boundary is established. The model is verified by using the C class aircraft B737-800 and the D class of aircraft B747-400 as the paired aircraft on the base of relevant data of Hongqiao international airport. The results show that the proposed method can be used to quantitatively calculate the safe zones of the paired approaches in real time.
