[0076] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0077] The embodiment of the present invention provides an aviation flight management method, see Figure 1 FIG. 1 is a flow chart of an aviation flight management method provided by an embodiment of the present invention in a first embodiment, wherein the method comprises steps S1 to S2:

[0078] Step S1, establishing a preliminary flight plan based on the acquired aircraft data information;

[0079] Step S2: performing flight route planning according to the preliminary flight calculation and the obtained flight departure plan;

[0080] Step S3, determining the take-off alternate airport and landing alternate airport that meet the alternative conditions according to the take-off and landing airports of different routes in the flight route planning, and determining the alternate landing result;

[0081] Step S4, calculating aircraft performance indicators of different routes according to the take-off alternate airports and landing alternate airports of different routes in the flight route planning;

[0082] Step S5: perform a flight operation evaluation based on the flight route planning, the alternate landing result, and the aircraft performance index, and output the flight route planning that passes the evaluation as a flight operation plan.

[0083] In the specific implementation of this embodiment, first, after determining the flight plan of the air carrier, a new flight plan database is established. This stage mainly involves building a flight launch task distribution platform, distributing the flight launch tasks to various departments of the operation control center, and establishing a preliminary flight plan based on the acquired aircraft data information.

[0084] The flight route planning is carried out according to the preliminary flight calculation and the obtained flight departure plan, that is, the route planning is automatically carried out according to the flight departure plan pre-published by the air carrier, so that the carrier can further calculate the route, make the operation review plan and apply for the flight. This module mainly carries out route planning according to the pre-published flight departure plan.

[0085] Determine the take-off and landing alternates and landing alternates that meet the alternative conditions according to the take-off and landing airports of different routes in the flight route planning, determine the alternate results, evaluate the take-off and landing alternates according to the take-off and landing airports, and list the alternates that meet the conditions. If the company's route exceeds 600 nautical miles, it is necessary to add route alternates, screen out the take-off and landing alternates that meet the conditions, and form an available alternate database.

[0086] According to the take-off and landing alternate airports of different routes in the flight route planning, and according to the company routes produced, the aircraft performance of the company routes and take-off and landing airports is evaluated to determine whether the company routes require drift and decompression procedures and whether they meet the oxygen capacity requirements, and whether ETOPS extended range operations are required. Determine the maximum take-off weight, maximum payload, and maximum landing weight of the aircraft during take-off and landing, whether there are temperature restrictions that require load limits, and calculate aircraft performance indicators for different routes.

[0087] A flight operation assessment is performed based on the flight route planning, the alternate landing results and the aircraft performance indicators. According to the flight plan, company routes, route calculation results and alternate landing field assessment results, two processes are required: assessment of special route operation requirements and preparation of flight review flight plan. An application for flight departure is submitted for review, and the flight route planning that has passed the assessment is output as a flight operation plan.

[0088] This case established a flight pre-flight plan management system, sorted out the entire process from planning to application for new flights, and transformed the scattered application of new flight tasks in different scenarios of the company's operation control into refined, systematic and modular management of new flight tasks, reducing the problems of low task processing efficiency and delayed information transmission caused by the low integration rate of independent data of departments, improving management efficiency, and promoting the informatization process of airline operation control. By building a flight pre-flight plan management platform, the digitalization, integration and intelligence level of flight pre-flight plan management was improved.

[0089] In another embodiment provided by the present invention, the method further includes:

[0090] Before the execution of the flight to be executed in the flight operation plan, the route data is updated, and the alternate landing results and flight performance indicators of the route are recalculated;

[0091] Acquire navigation notification data, and perform restricted area inspection on the flight to be executed based on updated route data, recalculated alternate landing results, and flight performance indicators according to the navigation notification data;

[0092] After the pending flight passes the inspection, the pending flight information is sent to the area along the route for route application;

[0093] receiving the approved route of feedback, and comparing the approved route with the flight to be executed;

[0094] After the approved route is compared and found to be consistent with the flight to be executed, the aviation flight plan is generated according to the approved route.

[0095] When this embodiment is implemented, see Figure 2 , is a flowchart of a specific implementation of the aviation flight management method provided by an embodiment of the present invention.

[0096] When the flight operation plan is output, the final flight inspection is carried out one week before the flight is executed to check the company's route data, flight calculation data, and alternate airport data. At the same time, the navigation notice inspection is carried out for the company's routes and take-off and landing airports and alternate airports to check whether there are restricted areas along the route affected by the navigation notice, the airport's curfew time and fire level.

[0097] The required data include: the flight plan database for new flight missions includes: flight number, expected flight date (year, month, day), departure airport, landing airport, aircraft type and tail number.

[0098] The company's route database includes: waypoints, route routes, take-off and landing airports, take-off and landing airport runway numbers, oxygen capacity required for the route, and flight time.

[0099] The NOTAM database includes NOTAMs for take-off and landing airports and NOTAMs for the company's routes and the information regions it flies over.

[0100] The aeronautical information database includes AIP airport curfew data.

[0101] Apply to the authority and flyover areas along the way for the company's routes, flight dates and times.

[0102] Required data: The company's route database includes: waypoints, route routes, take-off and landing airports, entry and exit points, regional and information area boundary points and time of arrival at information area boundary points.

[0103] New flight mission flight plan database: flight number, expected flight execution date (year, month, day), departure airport, landing airport, aircraft type, tail number, take-off time and landing time.

[0104] The above data will be submitted to the Civil Aviation Administration and other regions for flight and route approval. The approved route received will be compared with the applied route to see if they are consistent. If they are consistent, they will be used for flight plan preparation after the flight starts. If the route or flight is inconsistent, the original applied route will be modified and used for flight plan preparation.

[0105] In another embodiment provided by the present invention, the step S2 specifically includes:

[0106] Based on the acquired AIP database, aircraft model data, flight route compilation data and dynamic and static restriction database, search for routes that meet the flight information in the flight plan and whose take-off and landing places meet the control restrictions;

[0107] If a route is found, determining whether the found route meets the restricted area conditions in the flight route compilation data;

[0108] If it meets the requirements, the route that meets the requirements is output as the route planning of the flight;

[0109] If no route can be found or the searched route does not meet the restricted area conditions, the flight route compilation data is searched for a take-off place or a route that meets the control restrictions, and the searched take-off place or landing place is used as the starting point for searching, and the route is extended with the take-off places and landing places of different routes, and the route between the take-off place and landing place of the flight information is expanded, and the route with the shortest path that meets the restricted area conditions in the flight route compilation data is output as the flight route planning.

[0110] During the specific implementation of this embodiment, the AIP database, aircraft model data, flight route compilation data, and dynamic and static restriction databases are obtained.

[0111] New flight mission flight plan database: flight number, expected flight execution date (year, month, day), departure airport, landing airport, and aircraft type.

[0112] AIP database: waypoints, airway routes, departure procedures for take-off airports, approach procedures for landing airports, take-off airport runway number, landing airport runway number, waypoint coordinates, information area to which the waypoints belong, names and coordinates of restricted areas in various regions.

[0113] Aircraft data: aircraft model, oxygen capacity, cruising altitude, speed

[0114] The Air Traffic Control No. 1 Database, also known as the flight route compilation: take-off airports, landing airports, air routes, and waypoints mainly provide fixed route directions for more than one hundred city pairs.

[0115] Dynamic and static restriction database: including navigation notice restriction database and air traffic flow restriction database. The data mainly includes: horizontal restrictions: waypoints and their affiliated information areas, restricted airspace coordinates published in AIP and European and American RAD documents, restricted airspace content E item of navigation notice and activation time, i.e. F item and G item of the notice, AIP mandatory direction regulations: waypoints, routes, take-off conditions, overflight conditions and landing conditions; vertical restrictions: mandatory flight altitude, restricted airspace altitude published on AUP / UUP websites of various regions, and restricted airspace altitude announced.

[0116] Company route production based on new flight plans, and company route production based on the above five databases. If there is an ATC No. 1 route between the city pairs (take-off-departure point / entry point-landing airport) in the flight plan, if the route is found, determine whether the searched route meets the restricted area conditions in the flight route compilation data;

[0117] If it meets the requirements, the route that meets the requirements is output as the route planning of the flight; then the route of the air traffic control No. 1 order is extracted;

[0118] If no route can be found or the searched route does not meet the restricted area conditions, then find the route with the same take-off (entry point) / landing (exit point) airport in control No. 1, take each point of the same route with the take-off (entry point) / landing (exit point) airport as the starting point, and extend the route with the same take-off (entry point) / landing (exit point) airport until it is extended to the landing airport / take-off airport. In the extension process, it is necessary to consider the regional operation restrictions at the same time, first consider the horizontal restrictions and then the vertical restrictions, and then use the genetic algorithm to output the shortest path route extending from the take-off airport (entry point) / landing airport (exit point) that meets the restricted area conditions.

[0119] In another embodiment provided by the present invention, the step S3 specifically includes:

[0120] Determine the airport within a preset distance range based on the take-off and landing places in the flight route planning as the center of the circle;

[0121] Determine the initial screening results that meet the approval conditions by obtaining the airport approval status in the operation specification database;

[0122] The airport fire protection level in the initial screening results is matched with the aircraft fire protection level, and the take-off alternate field and landing alternate field that meet the conditions for regular operation are screened out to obtain the alternate landing result.

[0123] In the specific implementation of this embodiment, the take-off and landing alternates are evaluated according to the take-off and landing airports, and the alternates that meet the conditions are listed. If the company's route exceeds 600 nautical miles, it is necessary to add route alternates.

[0124] Required relevant data:

[0125] New flight mission flight plan database: flight number, expected flight execution date (year, month, day), departure airport, landing airport, and aircraft type.

[0126] Company route data: waypoints, route routes, take-off and landing airports, take-off and landing airport runway numbers, oxygen capacity required for the route, and flight time.

[0127] Aeronautical information database: civil aviation airport data (fire level, operating hours).

[0128] Aircraft model database: aircraft model, oxygen capacity, cruising altitude, speed, time and distance of a 60-minute flight with one engine outage.

[0129] Operations specification database: airports, operations specification approval status (R, A, ETOPS).

[0130] With the take-off airport and landing airport as the center of the circle, the distance that the aircraft flies for 60 minutes with one engine failure is extracted from all airports within the radius, and the airports approved as R (scheduled available airport) and A (alternate airport) in the operation specification database are superimposed as the preliminary screening results.

[0131] Extract the airport fire protection level and match it with the aircraft fire protection level to ensure that the airport fire protection level is greater than the fire protection level required by the aircraft, and ensure that the airport operation time is HO / H24 (operation operation / 24 hours operation) HS (regular operation).

[0132] Based on the above screening conditions, the take-off and landing alternate airports and route alternate airports that meet the conditions are selected to form an available alternate airport database as the alternate landing result.

[0133] In another embodiment provided by the present invention, the step S4 specifically includes:

[0134] Calculate the oxygen capacity of the route to be flown according to the flight route planning and the acquired aircraft model database;

[0135] When the oxygen capacity does not meet the aircraft oxygen capacity requirement, obtaining the minimum route altitude MEA database, the company route data and the drift-down decompression data;

[0136] Determine the decompression procedure of the route to be flown according to the minimum route altitude MEA database, and formulate a decompression route when the MEA is greater than a preset value;

[0137] When the flight time of the route being flown exceeds the preset duration, the ETOPS index of the route being flown is determined;

[0138] Determine the maximum landing weight of the aircraft and the maximum payload requirements for different runways at the airport based on the weight restrictions of the take-off and landing airports on the route being flown;

[0139] When the maximum load requirement of the airport runway meets the maximum landing weight requirement of the aircraft, the alternate airports on the route are extracted and the evaluation indicators of the alternate airports are determined;

[0140] The decompression route, the ETOPS index and the alternate airport evaluation index are used as the aircraft performance index.

[0141] During the specific implementation, the company routes and aircraft performance at the take-off and landing airports are evaluated based on the company routes produced, whether the company routes require a drift and decompression procedure, whether the oxygen capacity requirements are met, and whether ETOPS extended range operations are required. Determine the maximum take-off weight, maximum payload, and maximum landing weight of the aircraft during take-off and landing, and whether there are temperature restrictions that require load limits. The required relevant data include:

[0142] New flight mission flight plan database: flight number, expected flight execution date (year, month, day), departure airport, landing airport, and aircraft type.

[0143] Company route data: waypoints, route routes, take-off and landing airports, take-off and landing airport runway numbers, oxygen capacity required for the route, and flight time.

[0144] Aeronautical information database: minimum route altitude MEA, route basic data, airport PCN data.

[0145] Aircraft model database: aircraft model, oxygen capacity, cruising altitude, speed, aircraft one-engine ceiling data, aircraft takeoff and landing weight limit table.

[0147] Database of available alternates: landing alternates and en-route alternates.

[0148] Operations Specifications Database: Airports, Operations Specifications Approvals (ETOPS).

[0149] According to the flight route planning and the acquired aircraft model database, the oxygen capacity of the route is calculated. The oxygen capacity of the current aircraft mainly includes 12-minute oxygen capacity, 22-minute oxygen capacity and oxygen cylinder capacity. When the oxygen capacity does not meet the aircraft oxygen capacity requirements, it is necessary to re-create the route that meets the aircraft oxygen capacity.

[0150] According to the minimum route altitude MEA database, company route data and drift-down decompression data, evaluate the decompression and drift-down procedure of the route being flown. When the MEA is greater than the single-engine ceiling of the aircraft, it is necessary to consider drift-down to create a drift-down route and a drift-down alternate airport.

[0151] According to the minimum route altitude MEA database, evaluate the decompression procedure of the route to be flown. When MEA>10000FT, a decompression route needs to be formulated.

[0152] Weight restrictions for aircraft take-off and landing airports: Based on the take-off and landing weight limit table, evaluate the aircraft's maximum take-off weight, maximum landing weight, and maximum payload requirements for different runways under the lowest and highest temperature conditions.

[0153] ETOPS Extended Range Operations: When the flight time on a route exceeds 6 hours, it is determined that extended range operations are required.

[0154] Alternate airport assessment: select one of the airports as the alternate airport considering its PCN value and airport weight restriction > the maximum landing weight of the aircraft corresponding to the aircraft model. If ETOPS is required, extract the enroute alternate airport, which satisfies its PCN value and airport weight restriction > the maximum landing weight of the aircraft corresponding to the aircraft model and is approved as ETOPS in the operation regulations.

[0155] The decompression route, the ETOPS index and the alternate airport evaluation index are used as the aircraft performance index.

[0156] Air carrier flight routes are planned by air carriers according to regional operation restrictions such as AIP, Air Traffic Control Order No. 1, and other requirements, and are used by airline operation control departments to apply for flights, calculate routes, and make flight plans in accordance with AIP waypoints and routes. Air carrier flight routes include company route codes, takeoff airports, takeoff runways, departure procedures, waypoints, route routes, approach procedures, destination airport runways, and destination airports.

[0158] Generate special demand data according to the flight route planning, the alternate landing result and the aircraft performance index, including: flight take-off time, flight execution time, flight execution season and average wind temperature during flight execution;

[0159] When the special demand data meets the preset demand data, the flight route planning that passes the evaluation is output as a flight operation plan.

[0160] In the specific implementation of this embodiment, two processes need to be carried out according to the flight plan, company route, route calculation results, and alternate airport assessment results: assessment of special route operation requirements and preparation of flight review plan, which will be submitted to the authority for review and application for flight departure.

[0161] Special flight requirements assessment: Evaluate the RNP, RNAV, RVSM, ADS-B, CPDLC / PBCS, polar operations, ETOPS, extended cross-water, and MNPS capabilities required for the flights planned to be performed based on the company routes produced.

[0162] Operational qualification review flight plan: Based on the new flight plan, the company's route production results, the route calculation phase results, and the alternate airport assessment results, the operational qualification application flight plan is calculated and sent to the Civil Aviation Administration for review by the air carrier.

[0163] Required relevant data: Flight plan database for new flight missions: flight number, expected flight date (year, month, day), departure airport, landing airport, aircraft type, tail number.

[0164] Company route database: waypoints, route routes, take-off and landing airports, take-off and landing airport runway numbers, oxygen capacity required for the route, and flight time.

[0165] Upper air temperature database: two types of average wind temperatures: summer and winter.

[0166] Route calculation database: aircraft model, oxygen capacity, cruising altitude, speed, aircraft one-engine ceiling data, aircraft take-off and landing airport weight restrictions, landing alternate airports, ETOPS route alternate airports (if any).

[0167] According to the above five databases, the additional data that needs to be considered and generated when entering the flight plan making system are as follows: the take-off time of the flight is based on 0000 (UTC) on the execution date, and the average wind temperature corresponding to the flight execution time is obtained based on the flight execution time matching the winter / summer flight season time.
