Description

Technical Field

[0001] The present invention relates to the technical field of civil aviation data processing, and in particular to a method for generating a flight plan for a new airport in a terminal area based on a transition principle. Background Art

[0002] With the rapid development of the civil aviation industry, more and more cities are beginning to expand or add new airports. The flight plan of a new airport is usually obtained by transferring and increasing the original airport. The flight plan refers to the flight information provided to the air traffic service unit about the aircraft completing a flight, which should include the flight number, registration number, aircraft model, departure airport, planned off-block time, destination airport, planned on-block time, flight route, flight route direction, cruising altitude, etc. The transfer principle is given by the Civil Aviation Administration. In airspace simulation, it is necessary to process the new flight plan of the original airport and the new airport according to the flight plan of the original airport and the transfer principle.

[0003] However, due to the small number of cities with two airports in China, most of the existing literature and journals describe the significance and impact of the transition at a macro level, such as "Interpretation of the Transition and Operation of Beijing Daxing International Airport". There is a lack of detailed interpretation of the transition principles and the feasibility of the transition methods. At the same time, there are few examples of generating flight plans for new airports in the terminal area based on the transition principles, and there is no relatively complete method so far. Summary of the invention

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a method for generating a flight plan for a new airport in the terminal area based on the transition principle. The method classifies and sorts out the common transition principles, and on the basis of a comprehensive analysis of the transition principles, determines the transition flights and increments them, so as to provide a flight plan reference for simulation modeling.

[0005] The technical solution of the present invention is: the method for generating a flight plan for a new airport in a terminal area based on the transition principle comprises the following steps:

[0006] (1) Determine the baseline flight plan;

[0007] (2) Statistical baseline flight plan flight status;

[0008] (3) Analyze the transfer principles: determine the total number of transfer flights and the number of flights per day at each airport after the transfer, determine the transfer situation, determine the flight transfer ratio and the minimum / maximum number of flights;

[0009] (4) Determine the transfer flights based on the transfer principle;

[0010] (5) Increase the number of flights after the transfer to meet the daily landing and take-off requirements.

[0011] The present invention determines a baseline flight plan, counts the baseline flight plan flight situation, and analyzes the transfer principle: determines the total transfer flights and the daily landing and landing flights of each airport after the transfer, determines the transfer situation, determines the flight transfer ratio and the minimum / maximum flight, determines the flight of the transfer based on the transfer principle, and increments the flight after the transfer to meet the daily landing and landing requirements. Therefore, the present invention classifies and sorts out common transfer principles, determines the transfer flights and increments based on a comprehensive analysis of the transfer principles, and provides a flight plan reference for simulation modeling. This method can be applied to different transfer principles and has a wider applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] (4.1) For flights that require full relocation, all flights of the corresponding category will be relocated to the new airport;

[0064] (4.2) For all flights that require reservation, all flights of the corresponding category will be retained at the original airport;

[0065] (4.3) For partially transferred flights, the transfer shall be carried out to meet the minimum required flight volume;

[0066] (4.4) For flights with a determined transfer ratio, transfer flights are randomly selected according to the corresponding ratio when the transfer conditions are met, and the take-off and landing ratio before and after the transfer must remain unchanged;

[0067] (4.5) For a given minimum ratio of flights, transfer flights are randomly selected at the minimum ratio while meeting the transfer conditions.

[0074] (5.1) Determine the incremental ratio based on the number of flights before and after the incremental increase;

[0075] (5.2) Randomly select flights for increment according to the increment ratio, and increment the take-off airport, landing airport, aircraft type, reference type, reference point, flight route,

[0076] The flight transit points and cruising altitude are the same as those in the baseline flight plan. To avoid duplication of the flight number and registration number, suffixes such as _1 and _2 are added to the flight number and registration number of the original baseline flight plan. The reference time fluctuates randomly by 0 to 10 minutes based on the reference time of the original baseline flight plan.

[0077] The method of the present invention is described in more detail below:

[0078] 1. Determine the baseline flight plan:

[0079] Taking the transfer of Chengdu Shuangliu International Airport to Chengdu Tianfu International Airport as an example, the maximum single-day flow of the flight plan of Chengdu Shuangliu International Airport in the 2021 summer flight season was counted, and the flight plan on the corresponding day with a daily traffic volume of 90% to 95% of the maximum single-day flow was selected as the baseline flight plan.

[0080] 2. Statistics of flights in the baseline flight plan:

[0081] The original airport has 1,144 flights taking off and landing per day. Among them, Air China has 241 domestic flights and 25 international flights; Sichuan Airlines has 180 domestic flights and 35 international flights; China Eastern Airlines has 130 domestic flights and 12 international flights.

[0084] Air China will retain 167 flights. Sichuan Airlines will retain 132 flights. China Eastern Airlines will retain business routes such as Beijing, Shanghai, Kunming, and Hangzhou, with no more than 42 flights per day. Chengdu Airlines will retain 44 flights per day. Tibet Airlines will retain all flights. Cargo airlines will retain all flights. All flights to Hong Kong, Macau, and Taiwan will be retained. All other airlines will relocate.

[0085] 4. Confirm the transfer flight:

[0086] Air China transferred 103 flights. Sichuan Airlines transferred 88 flights. China Eastern Airlines transferred 98 flights. Chengdu Airlines transferred 22 flights.

The original airport has an incremental ratio of 1.1%, and the new airport has an incremental ratio of 65.2%. The flight plans of the two airports are incremented at this ratio. The take-off airport, landing airport, aircraft type, reference type, reference point, flight route, flight pass, and cruising altitude of the incremental flight plan are the same as the baseline flight plan. The flight number and registration number are added with suffixes such as _1 and _2 on the original flight number and registration number, and the reference time is randomly floating up and down by 0 to 10 minutes on the original reference time.

[0089] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the protection scope of the technical solution of the present invention.
