Description
Technical Field
The invention relates to the technical field of civil aviation air traffic management, in particular to a method, a device and a storage medium for interval management of airport landing aircrafts.
Background
As shown in fig. 1, the five-sided flight is an approach mode of an aircraft adopted in an airport, and in an actual flight, the aircraft must approach and land through the five-sided flight normally, the technique of the five-sided flight of a pilot and the precise command of a tower have a great influence on the five-sided approach efficiency, and in the process of the five-sided flight, the monitoring of factors such as the five-sided interval, the speed, the high-altitude wind speed and the like of the aircraft has a great influence on flight safety and the approach efficiency.
Where pentagonal spacing refers to the longitudinal spacing between two aircraft that follow one behind the other on five sides. Since the flight of the aircraft on five sides is generally a gradual deceleration process, the five-sided separation between aircraft is gradually reduced. The longitudinal interval of the two machines when the front machine is grounded is called as a grounding interval, the interval of the two machines when the rear machine is cut into the course is called as an initial interval, and the difference between the initial interval and the grounding interval is called as a catching-up amount. The catch-up amount is the key to the allocation of the pentagonal interval. Factors influencing the catch-up amount are many, including but not limited to the size of a grounding interval, the position of a cut-in point, the combination of a front machine type and a rear machine type, the wind direction and the wind speed of a pentagon and the like; the smaller the required interval, the more sensitive the catch-up amount is to these influencing factors.
The existing five-edge flight management has the following problems: firstly, the management of the original system on the five-side interval is mainly judged by the experience of a controller, although the five-side interval has a standard in operation, the controller cannot control the five-side interval within a smaller interval standard due to the complexity of airport work and the limitation of manpower, and air traffic accidents can be caused once the reaction is not timely; on the other hand, the existing system cannot provide all the required information affecting the pentagonal interval for the controller, so the minimum pentagonal interval standard does not play a great role in the interval control work. Secondly, the stages of the current flight management system are not distinguished obviously, the requirements of the common flight stage and the five-side approach stage on the five-side interval and the catch-up amount of the aircraft are different, and meanwhile, the speed of the five-side approach stage is regulated according to the real-time interval and the high-altitude wind speed, so that a controller is required to allocate the five-side interval and the catch-up amount of the aircraft according to the flight stage, environmental factors and the characteristics of the aircraft, but the current controller only allocates according to the same catch-up amount standard, the refining degree is reduced, the controller is difficult to judge the final grounding interval, the working efficiency is reduced through long-time monitoring, and the burden of the controller is also improved. Thirdly, the decision of speed regulation by means of a single safety interval is different from the actual situation due to the lack of a prediction function. The existing five-side flight management system has the problems that the airport entrance efficiency is difficult to improve; the increasing demand for fine allocation of pentagonal intervals and the traditional allocation mode become main contradictions restricting the improvement of the pentagonal operation efficiency.
