摘要
近距平行跑道实施配对进近可有效提高繁忙机场终端区容量,解决拥挤问题。为保证配对进近安全运行,研究其纵向碰撞风险,基于定位误差分布和尾流避让要求,考虑配对进近2架飞机的运动过程和时间因素,建立近距平行跑道配对进近纵向碰撞风险评估模型,并给出模型中相关参数的计算公式。最后通过Matlab软件对一算例进行仿真计算,以验证模型的合理性。结果表明:随着时间的增加,配对进近2架飞机间的纵向碰撞风险不断增大,当前机到达跑道入口时,风险达到最大。
Paired approach to closed spaced parallel runways can effectively improve capacity of terminal, and also can solve congestion of busy airport. For ensuring safety operation of paired approach, the longitudinal collision risk of paired approach to closed spaced parallel runways was studied. Based on positioning error distribution and requirements on wake avoidance during paired approach, considering paired approach aircrafts moving process and time, a longitudinal collision risk safety assessment model of closed spaced parallel runways paired approach was built. The parameters in this model were determined by providing the calculation models. In the end, an example was calculated through Matlab to verify the model. It turns out that with increasing of time, the longitudinal collision risk between two paired approach aircrafts is gradually increasing and reaches its maximum value when leader aircraft reaches threshold of runway.
