Abstract

The present invention provides a forward-looking warning envelope modulation method based on navigation performance, which obtains the navigation mode, navigation performance evaluation value and cross-linking equipment input information of the warning system in the aircraft flight management system. Calculate the horizontal track prediction cross-section width based on the navigation performance of the horizontal track. On the basis of the horizontal track prediction cross-section width W, complete the forward-looking boundary, cross-section width and spread angle boundary. According to the forward-sight near-ground warning envelope and combined with the terrain database, Judging whether there is terrain or obstacles in front of the predicted flight path of the aircraft intruding into the warning range formed by the forward-sight near-ground warning envelope, and issuing a warning. By establishing the correlation between the navigation performance of the aircraft flight management system and the forward-looking warning boundary design strategy, the invention effectively reduces the occurrence of missed warnings when the navigation performance is degraded, and ensures flight safety.

Description

technical field [0001] The invention relates to the field of flight forward-looking warning, in particular to a forward-looking warning envelope modulation method. Background technique [0002] The ground proximity warning system performs basic mode and enhanced mode warning calculations by receiving flight data information from various types of airborne equipment, combined with the built-in terrain database, airport database, obstacle database and the current flight stage. When it happens, the voice and the image information of the terrain threat ahead will be output to remind the pilot to avoid the threat and effectively avoid the Controlled Flight into Terrain Incident (CFIT). [0003] In order to meet the navigation performance requirements of various flight missions and combat missions in different navigation stages of various types of aircraft, navigation systems with different navigation principles are equipped; at the same time, the continuity and availability of the...
