AI Technical Summary

Technical Problem

Traditional terrain collision prevention and alarm systems rely on a single data source and are susceptible to weather and terrain factors, resulting in low alarm accuracy and timeliness, limited early warning strategies, high pilot intervention, and poor system compatibility.

Method used

A terrain collision avoidance warning system based on aviation multi-source data is used to collect information from multiple data sources in real time, calculate the warning envelope based on the aircraft's own aerodynamic performance, and provide real-time avoidance and collision avoidance suggestions to improve flight safety.

Benefits of technology

It improves the accuracy and timeliness of the terrain collision avoidance system, reduces the pilot's operational burden, improves flight safety, enables adaptive adjustment of different aircraft models, and improves the compatibility of the algorithm.

Abstract

The invention discloses a terrain anti-collision warning system and method based on aviation multi-source data, and relates to the field of aviation early warning. The invention aims to calculate the alarm envelope by collecting the information of a plurality of data sources on the aircraft in real time and combining the aerodynamic performance of the aircraft, timely provide avoidance and collision avoidance suggestions, help a pilot to avoid collision with the ground or obstacles under the conditions of complex terrains, low-altitude flight or low visibility, improve the flight safety, and improve the flight safety. Therefore, the requirement for the terrain anti-collision function of aircrafts with different performances in different flight stages is met, and the accuracy and timeliness of terrain anti-collision early warning are improved.
