【摘要】：空中交通的安全和效率明显受恶劣天气的影响,在机场起飞着陆滑行区域(TMA)尤其如此。在此区域,除了受天气影响之外,潜在的气象回避路线还受到空中交通管制的严格限制。因此气象回避模型DIVMET被开发出来。该模型给出一条建议路线,可以通过正在形成雷暴但尚未在里面实施任何空中交通管制的场地。DIVMET被应用到香港国际机场的TMA区域,因为此处的空中交通管制(ATC)单位有兴趣通过模拟回避路线来提高管制员的工作量,尤其是用于管理进场飞机交通。ATC单位对模拟的回避路线进行目视检查,其结果令人满意,但是商定了用实际观察到的路线对模拟情况进行定量验证。本文选择了香港TMA区域内有雷暴且交通严重扭曲时的两种真实恶劣天气情况。但是,进行任何验证之前的主要目标是识别仅仅受到天气影响但并未显示任何管制标志的路线。在飞行位置数据的基础上完成路线选择,选择若干着陆航班,并分析与标准进场路线的偏差。结果显示,272架航班中大多数同时受到天气和管制的影响(60%),这突出表明空中交通管制员在恶劣天气下要安全有效地管理着陆交通是存在挑战的。只有少数受天气影响的航班(7%)未受到管制,可以用于验证。DIVMET模拟路线被传给当地空中交通管制员,证明了这些路线是潜在切实的回避路线。在TMA区域内的DIVMET气象回避路线模拟有一定参考价值,但是进一步的模型开发必须将管制纳入考虑,至少要考虑停候、近道和减速。
[Abstract]:The safety and efficiency of air traffic are clearly affected by inclement weather, especially in the take-off and landing area of the airport, where weather is the exception. Potential weather avoidance routes are also severely restricted by air traffic control. Therefore, weather avoidance model DIVMET has been developed. The model gives a suggested route. DIVMET can be applied to the TMA area of the Hong Kong International Airport by means of a site where thunderstorms are being formed but no air traffic control has been implemented therein. Because ATC units here are interested in increasing the workload of controllers by simulating avoidance routes. In particular, the ATC unit is used to manage the aircraft traffic. ATC units visually check the simulated avoidance routes, and the results are satisfactory. However, it is agreed to use the observed route to quantitatively verify the simulation. In this paper, we choose two real severe weather conditions in TMA area of Hong Kong, where there are thunderstorms and the traffic is seriously distorted. The main objective before any validation is to identify routes that are only affected by the weather but do not show any control signs. Route selection is completed on the basis of flight location data and several landing flights are selected. The results show that most of the 272 flights are affected by weather and control at the same time. This highlights the challenges for air traffic controllers to manage landing traffic safely and effectively in severe weather. Only a few weather-affected flights are not regulated. Can be used to verify that the .DIVMET simulation route is passed to the local air traffic controller. It is proved that these routes are potential and practical avoidance routes. The simulation of DIVMET weather avoidance routes in TMA region has some reference value, but further model development must take control into account. At least consider stopping, closing and decelerating.
