Embodiment Construction

[0015] Such as figure 1 Shown. The aircraft current position estimation method, integrated into the civil aviation data query system, includes the following steps:

[0016] (1) First determine the full flight time T of the aircraft. When there is an expected arrival time, the full flight time of the aircraft T = the expected arrival time of the aircraft-the aircraft take-off time. When there is no expected arrival time, the full flight time of the aircraft T = the planned arrival of the aircraft Time-the time the plane is scheduled to take off;

[0017] (2) Suppose the entire distance is S, the time from the start of take-off to the speed of the aircraft is t, and the speed of the aircraft is V from the start of take-off to the speed of the aircraft. According to experience, the speed of the aircraft is The time from the speed of the aircraft to the landing of the aircraft is also t, the flight speed of the aircraft from the flying speed of the aircraft to the aircraft landing is...

Abstract

The invention discloses a method for predicating a current position of an airplane. The method comprises the following steps of firstly calculating the percentage of the current stroke of the airplane to the total distance, obtaining current longitude and latitude of the airplane, and finally determining a city nearest to the airplane on a map. According to the method provided by the invention, a civil aviation data query system can effectively and accurately display the current position information of the airplane, so that the demands of people caring the current position of the airplane are met, and the performance of the civil aviation data query system is improved.

Description

Technical field [0001] The invention relates to the field of civil aviation, in particular to a method for estimating the current position of an aircraft. Background technique [0002] At present, civil aviation data query systems are generally installed in domestic airports, and the information and data of various flights are provided to the public through the civil aviation data query system. The existing civil aviation data query system cannot display the current position of the aircraft due to technical and data reasons, and therefore cannot provide information about the current position of the aircraft to the sender, pick-up person and others who are concerned about the current position of the aircraft. Summary of the invention [0003] The object of the present invention is to provide a method for estimating the current position of an aircraft, which is applied to a civil aviation data query system, so as to solve the problem that the current civil aviation data query system...
