Controlling method of waypoint flow

Abstract

The invention relates to a controlling method of waypoint flow. The controlling method of the waypoint flow comprises establishing a time slice containing a plurality of time ranges according to a time sequence, initializing the time ranges, enabling each time range to be in an open and free state, setting the pass frequency of a waypoint in different time ranges according to the flow control information of the waypoint, adjusting width of different time ranges according to the passing frequency, and marking the opening-closing state of the time range corresponding to the pass frequency to be a closed state when the passing frequency is zero. The controlling method of the waypoint flow describes and controls the trafficability characteristic of an aircraft of the waypoint at a specific time through the width change, the opening-closing change, and the free-non-free change of the time slice, is suitable for different flight sort algorithms, namely, can carrying out flexible sorting according to the properties of different aircrafts, and is easy to control and high in precision, and therefore the flow control of the waypoint can be effectively achieved, and conflicts are prevented from occurring.

Description

technical field [0001] The invention relates to the field of aviation management, in particular to a waypoint flow control method. Background technique [0002] At present, with the continuous and rapid development of civil aviation transportation, the air traffic flow is growing rapidly, the congestion of airports, airspace and route network nodes is serious, and the problem of route congestion and flight delay is prominent. Therefore, this has become a hot issue of widespread concern in the society. [0003] The currently emerging waypoint flow control methods are basically based on the foreign trailing interval (MIT) control method and combined with domestic actual application scenarios. However, the application effect of this method in China is not ideal. Specifically, the MIT control method is mainly to realize the control of aircraft-to-aircraft separation on a line (single route).

[0003] The currently emerging waypoint flow control methods are basically based on foreign trailing interval (MIT) control methods and combined with domestic actual application scenarios. However, the application effect of this method in China is not ideal.

Specifically, the MIT control method is mainly to realize the control of aircraft-to-aircraft separation on a line (single route). Since the reference object (i.e.: aircraft) in this method is dynamically changing, it is suitable for flexible use of airspace (i.e., In areas where aircraft can yaw and change altitudes arbitrarily) (such as Europe and the United States), when aircraft encounter conflicts at the meeting point, they can fly around; but for regions that require strict flight routes (such as: China), due to Unable to freely alleviate conflicts by flying around, yawing and changing altitudes, so there are more conflicts when routes converge

It can be seen that the MIT control method is less flexible for resolving such conflicts, and the effect of using it in domestic flow control is not ideal
