Embodiment Construction

[0048] The present invention will be further described below in conjunction with accompanying drawing.

[0049] The direct flight function of the aircraft involved in the present invention can only be executed when the current route is activated, and the direct flight program can be inserted at any time in the currently activated flight plan (FPL) to guide the aircraft to fly directly to the target waypoint along the track , or direct flight to the target interception segment along the track, the aircraft should return to the original activated route after the direct flight function is completed. The method for realizing the direct flight function of the present invention has two major steps: direct flight track prediction and direct flight guidance.

[0050] For direct flight trajectory prediction, the direct flight function trigger module in the airborne flight management system activates the direct flight function of the aircraft after receiving the direct flight instructio...

Abstract

The invention provides a direct flight path predicting method and a direct flight method in an airborne flight management system to solve the technical problem that an existing direct flight method cannot obtain a direct flight predicted path. The predicting method comprises: determining a circle center through a turning radius R and a current flight heading to make an arc and determine a turningend point P, thereby obtaining a direct flight predicted path of the direct flight to a target waypoint; determining a circle center through a turning radius R and a current flight heading to make anarc, and determining a tangent slope of the arc according to the cutoff angle phic to determine a turning end point P, thereby obtaining a direct flight predicted path of the direct flight to a targetcutoff segment. According to the direct flight path predicting method and the direct flight method in the airborne flight management system, a whole direct flight predicted path capable of realizinga direct flight function can be obtained, and the aircraft can be guided to fly along the predicted path based on the obtained direct flight predicted path.

Description

technical field [0001] The invention belongs to the field of airborne avionics systems, and relates to a direct flight path prediction method in an airborne flight management system and a method for realizing direct flight. Background technique [0002] General-purpose aircraft are becoming more and more popular, and are widely used in agriculture, forestry, animal husbandry, fishery, tourism, etc. The direct flight function is a way to execute the flight plan. During the flight, due to factors such as dangerous weather and air traffic control restrictions, the aircraft needs to deviate from the current active route and fly directly to a target waypoint or target cut-off segment. [0003] At present, in the airborne integrated electronic system, for the realization of the direct flight function, only the connecting flight segment from the current position of the aircraft to the target waypoint can be given, and the entire direct flight prediction track for realizing the dire...
