摘要: 为了准确预测机场终端区航空器飞行冲突风险,以便能最大程度地利用低空空域资源,通过整合考虑加速度的运输飞机轨迹模型和通用飞机随机轨迹模型,建立终端区航空器飞行冲突风险预测模型。以某机场为例,采用C语言编写仿真程序,模拟该机场终端区跑道中心20 km范围内的航空器飞行轨迹。预测不同通航活动区设置条件下的飞行冲突风险,并确定运输机场周边通航活动区范围。预测结果显示,飞行高度限制为1 000 m时,将案例机场的该低空空域划设为非管制的监视空域,通用飞机与运输飞机之间的飞行冲突风险小于2×10-5,处于可接受安全水平。

Abstract: In order to accurately predict the flight conflict risk of aircraft in the airport terminal and use the low-altitude airspace resources to the full, a model was built for predicting risk of aircraft flight conflict in airport terminal after integrating the transport aircraft trajectory model considering the acceleration and the random trajectory model of general aircraft. The model was applied to a certain airport in China. A program was complied,by using the C language,for the simulation.The aircraft trajectories within 20 km range of the terminal centered on the runway were simulated by computer. The risk of flight conflict was predicted for different traffic zone settings. The activity areas for general aircrafts near the terminal were determined by the computer simulation. The result shows that the flight conflict risk between the general aircraft and the transport aircraft is low than 2×10-5 for a aircraft taking-off or landing and meets the acceptable level of safety, when the flying height is limited to 1 000 m and the low-altitude airspace is designated as a monitoring airspace under no control.
