Abstract

The invention discloses a flight running time prediction method based on reliability, and belongs to the technical field of flight running time prediction. The method aims to solve the technical problem that flight running time under different reliability is difficult to accurately predict in the prior art. The method comprises the following steps: establishing a meteorological message and flightoperation basic database; based on the meteorological message and the flight operation basic database, at least two time periods are extracted from one day to serve as delay time windows respectively;establishing a quantile regression model of each delay time window based on the meteorological message and the flight operation basic database; and predicting flight operation time under different reliabilities according to flight planned departure time and the quantile regression model.

Description

technical field [0001] The invention relates to a method for predicting flight running time based on reliability, and belongs to the technical field of flight running time prediction. Background technique [0002] Flight operation is an important part of the air transportation system and consists of many complex links. Flight running time is the most intuitive indicator for passengers to evaluate the flight operation system. It is mainly composed of three parts: departure airport slide-out time, flight time, and arrival airport slide-in time. Among them, departure airport slide-out time and arrival airport time The taxi-in time is the ground taxiing phase of the flight, and the flight time is the en-route flight phase of the flight. The ground taxiing stage of the flight is mainly affected by the meteorological characteristics of the airport such as temperature, dew point temperature, cloud base height, wind direction, and wind speed, as well as the special airport weather ...
