A method for determining a climb gradient for a go-around of an aircraft based on flight data

Abstract

The application belongs to the field of aviation safety and flight data processing, and particularly relates to a method for determining a climb gradient of a reflight of an aircraft based on flight data, aiming to solve the problem of inaccurate climb gradient of a reflight of an aircraft. The application comprises: identifying a reflight action starting time and a reflight performance reconstruction time based on flight data of a target aircraft; correcting non-standard atmospheric environment factors and local geographical environment factors affecting the geometric height of the aircraft based on the flight data, obtaining the corrected geometric height of the target aircraft, and reconstructing a corrected flight path in combination with the real-time horizontal position of the target aircraft; and determining a net climb gradient of a reflight of the target aircraft in an initial stage of the reflight from the reflight action starting time to the reflight performance reconstruction time according to the reflight action starting time, the reflight performance reconstruction time and the corrected flight path. The application can quantify the net climb gradient of the reflight containing the initial height loss, and truly restores the actual reflight performance of the target aircraft.
