Embodiment Construction

[0040]The flight stage of an aircraft can be divided into five parts, which are takeoff, climb, cruise, descent and landing. The aircraft takes off at the departure airport, climbs up to the cruising altitude after leaving the ground, and then cruises at the cruising altitude. Enter the descent phase at the point of descent until landing at the destination airport. The four-dimensional track is the time, horizontal position, altitude, vertical speed and other information of the aircraft during its flight phase.

[0041] see figure 1 .

[0042] The flow chart of the four-dimensional track prediction method based on historical track data mining is as follows: figure 2 As shown, the specific steps are as follows:

[0043] Step 1: Historical flight data and surveillance data processing

[0044] Historical flight data includes: flight number, estimated departure time, actual departure time, estimated arrival time, actual arrival time, waypoint, passing time, etc. Historical mo...

Abstract

The invention discloses a four-dimensional track estimation method based on historical track data mining. The steps include: 1. Obtaining four-dimensional track information according to the association relationship between historical flight data and monitoring data; 2. Constructing a historical four-dimensional track model of an aircraft ; 3. Carry out linear and non-linear fitting to the altitude and speed of the aircraft in the take-off and climb phases, level flight phases, and descent phases; 4. Analyze the horizontal trajectory of the aircraft in each flight phase; 5. Based on the above analysis results, establish an aviation Trajectory extrapolated vertical profile, horizontal profile and velocity profile models. Compared with the four-dimensional track model commonly used in control systems, the method of the present invention is simpler and more practical, and the accuracy of track estimation is higher. Key technologies such as forecasting and formulation of traffic allocation measures provide basic guarantees.

Description

technical field [0001] The invention belongs to the technical field of civil aviation air traffic management, and in particular relates to air traffic control conflict detection, air traffic flow prediction, arrival and departure sorting, track-based operation, design and verification of air traffic control decision support tools, and the like. Background technique [0002] The air transport industry plays an important role in promoting the world's economic and social development. Statistics from the International Civil Aviation Organization show that the global air traffic volume doubles approximately every fifteen years, and the operating capacity of the existing air traffic navigation system is close to saturation. In order to adapt to the rapid development of the aviation industry in the future and solve problems such as air traffic safety, airspace congestion, and flight delays, countries are committed to conducting research on new technologies to solve future air traff...
