Method for generating control assistance decision instruction based on required time of arrival

Abstract

The invention discloses a method for generating a control assistance decision instruction based on required time of arrival (RTA). The method comprises the following steps of: constructing an aircraft initial intention model, an external environment model and a particle model required by four-dimensional flight path prediction; and performing flight path prediction on an aircraft to obtain an initial four-dimensional flight path and the estimated time of arrival of a waypoint; obtaining the RTA of the waypoint by using a flight ordering and conflict release function in a control automation system or a control auxiliary decision system; optimizing the initial four-dimensional flight path of the aircraft; displaying the predicted horizontal trajectory and the vertical profile of the aircraft in an air traffic control assistance system and directly generating a control instruction that should be issued by a controller to a pilot. The method quickly generates the control instruction through the flight path prediction and flight path optimization. The instruction and the flight path planned by the method are easy to operate and good in controllability to the pilot, and can enable the aircraft to pass the waypoint according to the required arrival time.

Description

technical field [0001] The invention belongs to the technical field of civil aircraft air traffic management, relates to the field of air traffic control automation and intelligence, and the field of air traffic control decision support tools, in particular to a control auxiliary decision instruction generation method based on required arrival time. Background technique [0002] With the rapid growth of air traffic flow, airspace congestion is becoming more and more serious, resulting in increased flight delays and increased difficulty in conflict deployment, which have become a major problem in current control work. At the same time, the work pressure of control is also increasing day by day, and the control methods judged by experience in the past can hardly meet the needs of current operation, so it is necessary to seek innovation in control equipment and control methods. For the air traffic management department, the control decision-making support system is an effective...

Problems solved by technology

[0009] However, it is worth noting that the above-mentioned research is still in the stage of operational concept design and prototype system verification, and has the following two shortcomings before practical application: First, the control assistance system only provides "the effect that should be achieved" for the controller, and does not The specific control method is difficult for the controller to implement, and it is still difficult to solve the problem of making the aircraft pass the point on time; the second is that the trajectory planning based on the required arrival time is completed by the airborne, compared with the ground airborne The meteorological detection range is small, and the aircraft in the airspace cannot be considered comprehensively. At the same time, this strategy needs to achieve a breakthrough in ground-air data communication technology
