Route segment operation time calculation method based on clustering characteristics

Abstract

The invention relates to a route segment operation time calculation method based on clustering characteristics. The method for calculating the flight segment operation time based on the clustering characteristics comprises the following steps: obtaining a division result of resplitting a flight segment operation stage; Acquiring flight historical data; And for flight historical data of different flight segment operation stages, calculating flight segment operation time according to the clustering characteristics. The method comprises the following steps: firstly, obtaining flight historical data, resplitting the flight segment operation stages, carrying out clustering analysis by using the flight historical data, associating the flight historical data with time slices, determining the operation time of each stage according to the space-time characteristics of a clustering result, further obtaining comprehensive flight segment operation time, and providing a chemical data basis for thestrategy of air traffic flow management and a pre-tactical stage.

Description

technical field [0001] The invention relates to the field of aviation, in particular to a method for calculating flight segment running time based on clustering features. Background technique [0002] my country's development has entered a new stage and a new era, which puts forward new requirements for the development of civil aviation. At present, limited and inflexible civil aviation transportation resources can no longer meet the development needs of civil aviation transportation. It is particularly important to effectively carry out supply-side reform of the civil aviation industry and use civil aviation resources reasonably and flexibly. [0003] Flight slot is such a civil aviation transportation resource, and its allocation will eventually be reflected in the flight plan. When making a flight plan, an important reference data is the flight segment standard operating time. Aiming at the problem that the flight segment time proposed by the airline is based on itself, ...

AI Technical Summary

Problems solved by technology

[0004] In general, the current status of the research on the calculation method of flight segment running time is as follows: 1. The traditional probability statistics method used by airlines is too rough, unable to reflect the characteristics and differences in operation, and has low applicability, which cannot meet the needs of civil aviation operation management departments. Requirements for refined management; 2. The simulation estimation method based on aircraft performance is suitable for calculating the target operating time in an unobstructed state, but it cannot fully consider the actual operating factors, including seasonal changes, airport / airspace traffic capacity, etc., the actual reference value is weak; 3. Research based on measured data currently considers the division of surface taxiing and air phases, but does not consider the division of different phases of air operations, and makes separate estimates according to different operating characteristics
