A kind of flight flow pre-control method

Abstract

The present invention relates to a flight flow pre-control method, which includes the following steps: step S1, determine the planned route data of all planned flights that will occupy flight resources on the next day; The time data required for the historical flights with the same model data of the planned flights to fly through each waypoint in the planned route under the meteorological conditions and flight load conditions; The time data of each waypoint in the route; Step S4, calculate and obtain the time data of each planned flight arriving at each sector and the time data of leaving each sector; Step S5, judge the number of times that each sector accommodates in different time periods Whether the total number of all scheduled flights is greater than the preset sector capacity of each sector in different time periods. The invention can reasonably control the take-off time of the planned flight in advance, so that the resources of the airport and the airspace can be more rationally used.

Description

technical field [0001] The invention relates to civil aviation flow control technology, in particular to a flight flow pre-control method. Background technique [0002] 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 airway congestion and flight delays is prominent, which has become a hot issue of widespread concern in the society. [0003] The current flight flow control method is mainly based on post-event control, which mainly leads to the following shortcomings: [0004] (1) Once the flow in certain sectors and control areas exceeds the limit, the controller will temporarily request flight flow restrictions, which will cause subsequent flights to wait on the ground, resulting in increased flight delays; and due to this Uncertainty in the control method, it is not clear when the flights on the ground will be rest...

AI Technical Summary

Problems solved by technology

[0004] (1) Once the flow in certain sectors and control areas exceeds the limit, the controller will temporarily request flight flow restrictions, which will cause subsequent flights to wait on the ground, resulting in increased flight delays; and due to this Uncertainty in the control method, it is not clear when the flights on the ground will be restricted by flow control, which will bring great inconvenience to passengers; at the same time, many delayed flights have already arranged resources, which will cause waste of resources

[0005] (2) Due to the delay of this control method, a lot of flow control information will be transmitted downwards, resulting in layer-by-layer coding, which will lead to waste of route resources

[0006] (3) Post-event flow control will lead to flow alarms in certain waypoints and areas, resulting in unbalanced distribution of resources, and the planned departure time of flights will be concentrated in certain time periods, which will lead to concentration of flight time slots and artificially cause flight delays

[0007] (4) The flight information based on the existing flow control method is usually based on the historical data of yesterday's flight to predict today's flight data; and in the actual operation process, it will be found that the data has a certain deviation
