A 4D Track Prediction Method Based on Control Intent and Aircraft Performance Model

Abstract

The invention discloses a four-dimensional track prediction method based on control intention and aircraft performance model, which can use initial plan information when the flight does not take place, combined with the experience altitude of the flight passing through each reporting point obtained from historical data mining. The empirical data reflecting the control intention establishes the aircraft dynamics model, and at the same time considers the meteorological conditions, predicts the 4D track point sequence that the flight will generate in advance, and dynamically corrects the 4D prediction results of the flight after receiving the monitoring data. The invention improves the accuracy of flight 4D trajectory prediction, helps to detect flight conflicts and flow management decisions in advance, and relieves air traffic pressure.

Description

technical field [0001] The invention belongs to the technical field of aircraft four-dimensional (4D) track prediction in an air traffic management system, and specifically refers to a four-dimensional track prediction method based on a control intention and an aircraft performance model. Background technique [0002] As an important industry in my country's national economy and social development and an advanced mode of transportation, the civil air transportation industry has also developed rapidly along with the continuous development of the entire national economy. By 2017, the total number of civil aviation airports in China had increased from 94 in 1990 to 216, with a total of nearly 4,000 routes. There are more and more aircraft on the flight route, and the flight distance is getting smaller and smaller, and the air traffic safety situation is becoming more and more severe; problems such as flight delays and airspace congestion also occur frequently. Flight delays no...
