Controlling method of waypoint flow

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
