A method for updating the location information of navigation passing points suitable for irregular flights outside the route

Abstract

Provided is a position information updating method suitable for irregular-flying navigation through points out of airways. The position information updating method comprises the steps of acquiring the horizontal deviation and the height deviation of the course and the current position of an all-purpose aircraft relative to the arrival position predicted by a flight plan according to flight plan data and flight path data, judging whether the current horizontal deviation and the height deviation of the all-purpose aircraft can both meet threshold values, judging whether the all-purpose aircraft flies in the planned course, carrying out coarse processing in a preset range, judging whether the all-purpose aircraft flies to be close to the planned course, and carrying out fine processing in the preset range. The position information updating method can use different processing methods to update predicted through point position information in real time according to different flight plans and improve the accuracy of updating the through point position information when the aircraft irregularly flies and yaws out of flight paths.

Description

technical field [0001] The invention belongs to the technical field of aviation automatic control, and in particular relates to a method for updating position information of a navigation passing point suitable for irregular flights outside the air route. Background technique [0002] With the gradual opening of my country's low-altitude airspace, the demand for general aviation flights will increase sharply. For general aviation with autonomous and diverse types of flight, the current civil aviation system is difficult to provide flexible and reliable flight service support, and general aviation flight safety technical support methods are currently relatively scarce. . [0003] The update of the aircraft's expected passing point position information is used to assist the flight service station personnel to grasp the flight dynamics of the aircraft during the flight of the aircraft, so as to ensure the safe flight of the aircraft. Transport aviation pilots fly along the route...

AI Technical Summary

Problems solved by technology

Transport aviation pilots fly along the route in strict accordance with the scheduled flight plan. However, for general aviation, the aircraft is greatly affected by the ground airflow, and the flight track changes drastically. Unable to strictly implement the flight plan, which may cause the general aircraft to fly out of the route and fly irregularly, making it more complicated for the aircraft to update the position information of the expected passing point during the flight

The existing technology can no longer meet the needs of general aviation, therefore, a new technical solution is needed to solve the above problems
