Method for judging flight stage based on airborne near-earth alarm system

Abstract

The invention provides a method for judging a flight stage based on an airborne near-earth alarm system. The method comprises the steps that S1, data information of the real-time height, speed, position, heading, posture, air pressure height change rate, undercarriage folding and unfolding speed, throttle lever position and radio height of an aircraft is collected by collecting devices connected with an input end of an airborne near-earth alarm system; S2, according to the data information collected in the step S1, the flight stage of the aircraft is calculated, analyzed and judged by the airborne near-earth alarm system; and S3, according to the flight stage obtained in the step S2, the airborne near-earth alarm system schedules each alarm model to give out or not give out an alarm. According to the method, the flight stage can be accurately judged only according to airborne information data feedback without loading an airport database; the judgment of the flight stage is efficient, timely, accurate and reliable; further, each alarm model is effectively scheduled, so that the false alarm rate of the enhanced near-ground alarm system is reduced; flight safety is improved.

Description

technical field [0001] The invention specifically relates to a method for judging a flight phase based on an airborne ground proximity warning system. Background technique [0002] The enhanced ground proximity warning system refers to collecting airborne information such as altitude, speed, position, heading, attitude, take-off and landing configuration of the aircraft, judging the flight stage after signal processing, and dispatching different warning models in different flight stages; When it is judged that there is a potential danger of the aircraft hitting the ground, it will send a warning to the pilot to ensure flight safety. It can be seen that if the judgment of the flight phase is inaccurate, the alarm model suitable for the current aircraft cannot be accurately scheduled, resulting in a large number of false alarms. In the prior art, the commonly used method for judging the flight phase of the EGPWS mainly relies on the feedback from the airport database to judge...

AI Technical Summary

Problems solved by technology

Since the judgment of the flight phase depends on the feedback of ground airport data, the real-time and accuracy of the judgment of the flight phase are not high, and there are hidden dangers of false alarms caused by misjudgment of ground data feedback
