Description
Technical Field
[0001] The present application relates to the field of data processing technology, and in particular to a runway recommendation method, apparatus, computer equipment, storage medium, and program product. Background Art
[0002] For civil aviation operations, an airport has at least one runway, and each runway has two runway directions. The departure distance and approach distance of aircraft on different runways and different runway directions of the same runway are different, which will affect the takeoff fuel volume of the flight.
[0003] However, numerous factors influence airports' decisions about which runway to use and in which direction, and each airport's rules vary. For airlines, if they can't predict in advance which runway and direction they will use for takeoffs and landings, using the runway with the maximum departure and approach distances and the corresponding runway direction will cause a discrepancy between the planned and actual distances, leading to inflated takeoff fuel requirements and inaccurate flight times, impacting operational efficiency.

It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0060] Among them, the terminal 102 can be a smart phone, a tablet computer, a laptop computer, a desktop computer, an Internet of Things device and a portable wearable device. The Internet of Things device can be a smart speaker, a smart TV, a smart air conditioner and a smart car device, etc.
[0061] The server 104 may be an independent physical server or a service node in a blockchain system. Each service node in the blockchain system forms a peer-to-peer network. The peer-to-peer protocol is an application layer protocol running on top of the Transmission Control Protocol (TCP).
[0062] In one embodiment, Figure 2 As shown, a runway recommendation method is provided, which can be Figure 1 The server or terminal in the embodiment is executed, or the server and the terminal are executed in collaboration, in which method the Figure 1 The server execution in is used as an example to illustrate the following steps:
[0063] S202: Correct the wind components in each weather report according to the runway direction of each runway in the airport to obtain the vector wind volume in each runway direction.
[0064] The runway at an airport may be a runway used for takeoff and landing of flights at the airport, such as an aircraft runway used for takeoff and landing. An airport typically has multiple runways, and each runway has two runway directions, such as each runway has two takeoff directions (or landing directions) for aircraft.
[0065] Wind components may be wind direction and speed as described in a meteorological report. A meteorological report may refer to an airport weather forecast, including Meteorological Terminal Aviation Routine Weather Report (METAR), Terminal Aerodrome Forecasts (TAF), and European Centre for Medium-Range Weather Forecasts (EC), where:
[0066] METAR reports are routine reports of current airport weather conditions, typically at regular intervals of one or half hours. METAR messages contain real-time weather information such as wind direction and speed at the airport. Wind direction and speed can be the METAR wind component.
[0067] The TAF is a brief description of the expected weather conditions at an airport during a specific time period and is published at a specific time. The TAF message contains weather information such as wind direction and speed at the airport during that time period. These wind direction and speed can be the TAF wind component.
[0068] EC is a numerical weather forecast model developed by the European Centre for Medium-Range Weather Forecasts. EC messages also contain weather information such as wind direction and wind speed at the airport during a certain period of time. The wind direction and wind speed can be the EC wind component.
[0069] Vector wind volume can be defined as wind volume with wind components broken down into runway directions. This includes METAR vector wind volume, TAF vector wind volume, and EC vector wind volume. METAR vector wind volume can be defined as wind volume in the runway direction, including direction and speed. The same applies to TAF vector wind volume and EC vector wind volume.
[0070] In one embodiment, the server may first obtain the flight information data of the airport, and extract all runways, runway numbers, coordinates, headings, directions of each runway, and approach and departure distances of the airport from the flight information data.
[0071] Among them, the approach and departure distances can be a general term for approach distance and departure distance. The approach distance can be the distance between the last waypoint and the landing airport, and the departure distance can be the distance between the take-off airport and the first waypoint.
[0072] The approach distance and departure distance are part of the aircraft's flight distance, accounting for about 10% of the flight distance. In addition, the flight distance also includes the main segment distance, which is the distance between the first waypoint and the last waypoint.
[0073] In one embodiment, the server can obtain NOTAM data; shield the unavailable runways of the airport based on the NOTAM data to obtain the available runways of the airport; therefore, when performing wind component correction, the server can correct the wind components of each weather report according to the runway direction of the available runway to obtain the vector wind volume in each runway direction.
[0074] The unavailable runway may be due to runway maintenance or some uncontrollable factors.
[0075] The available runways and their corresponding runway directions form an initial candidate pool of available runway directions. Therefore, when correcting the wind components, the wind components of each weather report can be corrected according to the runway directions in the initial candidate pool, obtaining the vector wind volume for each runway direction in the initial candidate pool.
[0076] In one embodiment, the server can obtain meteorological message data of each meteorological report, and the meteorological message data includes METAR messages, TAF messages and EC messages during the flight operation period. The METAR message carries a METAR wind component, the TAF message carries a TAF wind component, and the EC message carries an EC wind component. Therefore, when correcting the wind component, the server can correct the METAR wind component according to the runway direction of the available runway to obtain the METAR vector wind volume in each runway direction of the available runway; correct the TAF wind component according to the runway direction of the available runway to obtain the TAF vector wind volume in each runway direction of the available runway; and correct the EC wind component according to the runway direction of the available runway to obtain the EC vector wind volume in each runway direction of the available runway.
[0077] S204: Score each runway direction based on each vector wind volume to obtain an availability score.
[0078] In one embodiment, the server may compare the magnitude of each vector wind volume with some preset vector wind volumes, score each runway direction based on the magnitude relationship, and obtain an availability score for each runway direction; then, the server may sum the availability scores corresponding to each weather report for the same runway direction to obtain a total availability score for each runway direction.
[0079] Among them, taking into account some complex weather conditions, the preset vector wind volume usually has a certain size of margin, and the size of the margin can be adjusted according to actual conditions, so that the size of the preset vector wind volume changes dynamically.
[0080] In one embodiment, considering that each vector wind volume includes a METAR vector wind volume, a TAF vector wind volume, and an EC vector wind volume, the server may score each runway direction in the available runways based on the METAR vector wind volume to obtain a first availability score; score each runway direction in the available runways based on the TAF vector wind volume to obtain a second availability score; score each runway direction in the available runways based on the EC vector wind volume to obtain a third availability score; and determine a total availability score based on the first availability score, the second availability score, and the third availability score.
[0081] For example, the availability score of the runway direction can be scored based on the size of the corrected METAR vector wind volume, TAF vector wind volume, EC vector wind volume and the corresponding preset vector wind volume. For example, the METAR forecast score is 50 points, the TAF forecast score is 20 points, the EC forecast score is 30 points, and the total score is 100 points. The corresponding scoring standard is: when the corrected vector wind volume of each runway direction is less than a certain size of the preset vector wind volume, a point can be scored. Taking the tailwind speed of 2 meters as an example, preset vector wind volumes of different sizes can be set. When the corrected vector wind volume of each runway direction is less than the preset vector wind volumes of different sizes, the corresponding availability score can be obtained; for the METAR vector wind volume, the full score is 50 points; for the TAF vector wind volume, the full score is 20 points; for the EC vector wind volume, the full score is 30 points.
[0082] It should be noted that the headwind speed is negative. If the preset vector wind volume is -2 and -3, the availability score when the METAR vector wind volume is less than -2 is lower than the availability score when the METAR vector wind volume is less than -3.
[0083] S206: If the availability score is not less than the preset threshold, the runway direction and the corresponding runway with the availability score not less than the preset threshold are added to an available runway direction candidate pool.
[0084] The preset threshold may be 50, 70, 80 or 100, and may also be dynamically adjusted according to actual conditions.
[0085] For example, if the availability score is greater than or equal to a preset threshold, the runway directions and corresponding runways with availability scores greater than or equal to the preset threshold are put into the available runway direction candidate pool.
[0086] It should be noted that the availability scores for runway directions on the same runway generally vary. For example, if the availability score of runway direction a of runway 1 is 70, the availability score of runway direction b of runway 1 may be 30. In this case, runway 1 and runway direction a will be added to the candidate pool of available runway directions.
[0087] In one embodiment, if the availability score is less than a preset threshold, the server may reduce the margin of the preset vector wind volume from high to low according to the size of the runway priority value to obtain multiple adjusted vector wind volumes; if the vector wind volume is less than the corresponding adjusted vector wind volume, then return to execute S204.
[0088] For example, the vector wind volume margin is reduced from high to low according to the runway priority value of the runway direction, thereby reducing the preset vector wind volume to obtain the adjusted vector wind volume. The METAR vector wind volume is compared with the adjusted vector wind volume. If the METAR vector wind volume is smaller than the adjusted vector wind volume, return to execute S204.
[0089] S208: If the available runway direction candidate pool has multiple runways, determine the runway usage rate of each runway direction in the available runway direction candidate pool, or determine the distance between the arrival and departure points and each runway in the available runway direction candidate pool.
[0090] The runway utilization rate may be the actual utilization rate of each runway direction of the runway within a certain historical time period.
[0091] In one embodiment, if the available runway direction candidate pool has multiple runways, the server may first determine whether the runway directions of the runways in the available runway direction candidate pool are in the same direction. If so, the server may calculate the runway usage rate of each runway direction in the available runway direction candidate pool. If not, the server may determine the distance between the approach and departure points and each runway in the available runway direction candidate pool.
[0092] S210 , based on the runway usage rate or distance, select a runway direction of a target runway from an available runway direction candidate pool for recommendation.
[0093] When making a recommendation, the selected target runway and the corresponding runway direction may be recommended. For example, if runway a and runway direction 1 are selected, the recommendation will be "Runway a and runway direction 1 are recommended for this flight."
[0094] In one embodiment, if the available runway direction candidate pool contains multiple runways, the server may determine whether the runway directions in the available runway direction candidate pool are in the same direction; if so, the server may select a target runway direction from the available runway direction candidate pool for recommendation based on the runway usage rate; if not, the server may select a target runway direction from the available runway direction candidate pool for recommendation based on the distance between the approach and departure points and each runway.
[0095] For example, if the runway direction in the available runway direction candidate pool is not unique, the runways in the pool are evaluated to see if they are in the same direction. This can be determined by subtracting the runway direction numbers; if the absolute value is not equal to 17, 18, or 19, the runway direction is considered to be in the same direction. If the result is the same direction, and a runway direction has been used frequently in the past cycle, the runway direction of that runway is output as the final recommended runway direction. If the result is different directions, the same arrival and departure point is output, and the runway with the farthest runway direction in the available runway direction candidate pool is selected as the final recommended runway direction.
[0096] In one embodiment, if the number of runways in the available runway direction candidate pool is one, the server may recommend a runway direction from the available runway direction candidate pool. If the number of runways in the available runway direction candidate pool is zero, the server determines whether there are any runways with aircraft taking off and landing during the target time period. If so, the server recommends the runway direction of the runway with aircraft taking off and landing. For example, the runway with aircraft taking off and landing and its corresponding runway direction are placed in the available runway direction candidate pool, and then the runway and its corresponding runway direction from the available runway direction candidate pool are recommended.
[0097] In one embodiment, for the case where there are multiple runways in the available runway direction candidate pool, in addition to the above-mentioned runway recommendation method, the following steps are further included: the server first determines the runway utilization rate of each runway direction at the same approach and departure point; determines the runway priority value of each runway direction based on the runway utilization rate; if there are multiple runways in the available runway direction candidate pool, calculates the product of the runway priority value of each runway direction and the vector wind volume of each runway direction; wherein the product value is a positive value; and in the available runway direction candidate pool, selects the runway direction corresponding to the largest product value for recommendation.
[0098] For example, when there are multiple runways in the available runway direction candidate pool, the runway priority values of all runways in the available runway direction candidate pool are multiplied by the absolute values of the vector wind volumes of the corresponding runways to obtain a product value, and the runway direction corresponding to the runway with the largest product value is used as the final recommended runway direction.
[0099] In one embodiment, if no runway direction is recommended after the above steps, the runway with the farthest distance from all runway directions of the arrival and departure point is recommended or no recommendation is made.
[0100] In the above embodiment, the wind components of each meteorological report are corrected according to the runway direction of each runway at the airport to obtain a vector wind volume for each runway direction; each runway direction is scored based on the vector wind volume to obtain an availability score; if the availability score is not less than a preset threshold, the runway direction and the corresponding runway with an availability score not less than the preset threshold are added to a candidate pool of available runway directions; if the candidate pool of available runway directions contains multiple runways, the runway utilization rate of each runway direction in the candidate pool of available runway directions is determined, or the distance between the approach and departure points and each runway in the candidate pool of available runway directions is determined; based on the runway utilization rate or distance, the runway direction of the target runway is selected from the candidate pool of available runway directions for recommendation. By combining the vector wind volume for each runway direction, the runway utilization rate, and the distance between the approach and departure points and each runway, the runway direction of the target runway can be accurately predicted, thereby precisely controlling the takeoff fuel and flight time of the flight and ensuring flight operational efficiency.
[0101] As an example, combining Figure 3 The solution of this application is explained as follows:
[0102] 001. Obtain flight information data and obtain all runways, runway numbers, coordinates, headings, and approach and departure distances of the runway directions.
[0103] 002. Obtain NOTAM data, mask unavailable runways and time periods based on the NOTAM data, obtain available runways and corresponding runway directions, and form an initial runway direction candidate pool of availability.
[0104] 003. Obtain weather message data, including the latest METAR message, TAF message and EC message during the flight operation period.
[0105] 004. Correct the METAR wind component in the METAR message to obtain the corrected METAR vector wind volume in each runway direction.
[0106] 005. Correct the TAF wind component in the TAF message to obtain the corrected TAF vector wind volume in each runway direction.
[0107] 006. Correct the EC wind component in the EC message to obtain the corrected EC vector wind volume in each runway direction.
[0108] 007. Runway Direction Availability Scoring: Scoring is based on the corrected vector wind volume for each runway direction. For example, the score for METAR messages is set to 50 points, TAF messages to 20 points, and EC messages to 30 points, for a total of 100 points. Scoring Criteria: Points are awarded when the corrected vector wind volume for each runway direction is less than a certain value. This example uses a tailwind of 2 meters, but different values can be set.
[0109] 008. Establish a candidate pool of available runway directions and include all runway directions of the airport whose availability scores are greater than a certain threshold into the runway direction candidate pool. The threshold can be set to 50, 70, 80 or 100.
[0110] 009. Calculate the runway priority value for each runway direction: Using the same approach and departure point as the dimension, calculate the runway utilization rate for each runway direction at the same approach and departure point in a certain period in the past, and determine the runway priority value based on the runway utilization rate.
[0111] 010. Runway Recommendation Method 1: When there are multiple runways in the available runway direction candidate pool, multiply the runway priority values of all runways in the available runway direction candidate pool by the absolute value of the vector wind volume of the corresponding runway to obtain the product value. The runway direction corresponding to the runway with the largest product value is the final recommended runway direction.
[0112] 011. Runway Recommendation Method 2: Reduce the margin of the preset vector wind volume from high to low according to the runway priority value to obtain the adjusted vector wind volume. Compare the METAR vector wind volume with the adjusted vector wind volume. If the METAR vector wind volume is less than the adjusted vector wind volume, return to step 007.
[0113] 012. If the available runway direction candidate pool is unique, then the runway is recommended as the final recommended runway.
[0114] 013. If the runway direction in the available runway direction candidate pool is not unique, evaluate whether the runways in the pool are in the same direction. To determine if they are in the same direction, subtract the runway direction numbers. If the absolute value is not equal to 17, 18, or 19, they are considered to be in the same direction. If the result is the same direction, and a runway direction has a high usage rate in the past cycle, then that runway direction is output as the final recommended runway direction. If the result is different, then the same arrival and departure point is output, and the runway direction corresponding to the runway with the farthest runway direction in the available runway direction candidate pool is selected as the final recommended runway direction.
[0115] 014. If the available runway candidate pool is empty, but there is a runway with real-time takeoffs and landings in the last 30 minutes of the airport, put the runway and the corresponding runway direction into the available runway direction candidate pool, and return to step 012.
[0116] 015. If there is still no recommended runway direction after the above steps, the runway with the longest distance from all runway directions of the arrival and departure point will be recommended, or no recommendation will be made.
