Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The flight plan generation method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104 or may be located on a cloud or other network server.
The terminal 102 may be, but not limited to, various personal computers, internet of things devices, and portable wearable devices, and the internet of things devices may be intelligent on-board devices, intelligent vehicle-mounted devices, and the like. The portable wearable device may be a headset device or the like. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.
The traditional manual secondary release flight plan is time-consuming and labor-consuming, and usually adopts fixed secondary release points to match with an initial release airport, so that two flight plans of flights from a take-off airport to the initial release airport and to a final destination airport need to be completely calculated. The secondary release plan of foreign products cannot meet the special regulations of domestic or partial areas; firstly, the data of the part of the navigation routes in China are not published externally, so that the secondary release plan calculated by foreign products cannot meet the special requirements of domestic operation; secondly, in some areas, the foreign products cannot meet special requirements and regulations; in addition, the fuel policies running at home and abroad are different from the special regulations of some companies, and external products cannot be flexibly configured according to the requirements of domestic airlines. Therefore, in generating a flight plan, it is necessary to accurately determine the secondary flight point.
In one embodiment, as shown in fig. 2, a flight plan generation method is provided, and the method is applied to the terminal 102 in fig. 1 for illustration, and includes the following steps:
step 202, a plurality of waypoints between a take-off airport and a destination airport are acquired.
The take-off airport is an airport for taking off an aircraft, the destination airport is a landing airport of the aircraft under normal conditions, and the landing airport can also be a landing airport of the destination airport, an initial release airport and a landing airport of the initial release airport. During the flight from the take-off airport to the destination airport, the aircraft will fly along the route between the take-off airport and the destination airport.
A plurality of waypoints between the takeoff airport and the destination airport, including at least a portion of the waypoints in the route between the takeoff airport and the destination airport. The positions of the waypoints can provide certain position data for the stages of climbing, cruising, descending and the like of the aircraft so as to facilitate the establishment and execution of a flight plan.
Optionally, the method further comprises: and calculating the weight of the airplane, the fuel margin and the arrival time of the airplane at each waypoint between the take-off airport and the final destination airport according to the minimum unpredictable fuel oil requirement based on the dynamic performance data of the airplane under the meteorological data of the route. Therefore, the fuel conditions are determined based on the weight of the aircraft and the arrival time of the aircraft, and a basis for screening alternative secondary release points is laid based on the fuel conditions and the fuel allowance.
And 204, selecting an alternative secondary release point from the plurality of route points according to the secondary release point condition.
The secondary release point condition is a data range defined by data such as the distance between different positions and a certain reference position; if some data between the positions of some waypoints and the reference positions are in the data range, the waypoints can be determined to be alternative secondary release points, and the alternative secondary release points are the waypoint range where the target secondary release points are located. When the reference position is the position of the take-off airport, a certain relative data is determined according to the position of the take-off airport and the position of the destination airport, another relative data is determined according to the position of the take-off airport and the position of the destination airport, and whether the waypoint in the relative data is an alternative secondary release point is judged according to the two sets of relative data.
In an alternative embodiment, selecting an alternative secondary clearance point from a plurality of waypoints in accordance with a secondary clearance point interval includes: determining a range distance between the takeoff airport and the destination airport based on the location of the takeoff airport and the location of the destination airport; determining the flight distance of each waypoint based on the position of the take-off airport and the position of each waypoint; determining the relative distance of each route point according to the route distance and the flight distance of each route point; and determining an alternative secondary release point based on the waypoints of the relative distance in the secondary release point interval.
The range distance and the flight distance of each route point are the distances determined by the aircraft according to the first-pass flight plan; the range distance is the distance an aircraft flies from a take-off airport to a destination airport, and the flight distance of each waypoint is the distance an aircraft flies from a take-off airport to a corresponding waypoint, each waypoint having its own flight distance.
The relative distance of each waypoint is the distance of the flight distance of each waypoint relative to the range distance, which may be a percentage or other form ratio of the flight distance of each waypoint to the range distance, or may be the flight distance of each waypoint to the range distance.
The secondary release point interval is defined according to the fuel information of the initial release and the secondary release in the process of the aircraft from each route point to the initial release airport. When the relative position of a certain waypoint is in the secondary release point interval, the distance from the waypoint to the initial release airport is smaller than the distance from the waypoint to the initial release airport. Illustratively, the relative distance is 70% -87% of the secondary pass-through point interval.
In an alternative embodiment, determining an alternative secondary clearance point based on waypoints of the relative distance between the secondary clearance points comprises: determining a critical value of a secondary release point interval; comparing the relative distance of each route point with the critical value of the secondary release point to obtain a comparison result of each route; judging whether the relative distance of each waypoint is positioned in a secondary release point interval according to the comparison result of each waypoint; and determining the secondary release point with the relative distance between the secondary release points as an alternative secondary release point.
Illustratively, a first leg distance between the take-off airport and a first waypoint is calculated, and each second leg distance between adjacent waypoints; the relative distance of each waypoint is determined based on the first leg distance and each second leg distance. Illustratively, the great circle distance between two waypoints is calculated by the distance longitude and latitude between adjacent waypoints. The distance from the take-off airport to each waypoint is obtained by using the calculated distance between the two waypoints, and the percentage of the waypoints in the total course is calculated based on the distance from the take-off airport to the final destination airport.
Although the secondary release points are not necessarily suitable for the initial release airport, the secondary release points are necessarily in the secondary release point intervals, so that the secondary release intervals are suitable for different routes, and in the process of screening the relative distances in the secondary release point intervals, the relative distances are calculated through the range distances and the flight distances, and the route points of the secondary release and fuel saving can be determined through the secondary release point intervals.
Step 206, based on the initial release airport and each alternative secondary release point, judging whether a secondary release point applicable to the initial release airport exists.
The initial discharge airport is set for the route, and is an airport which can discharge the flight for the first time. When the secondary release point suitable for the initial release airport does not exist, the minimum oil consumption between the initial release airport and a certain alternative secondary release point can only play a reference role, and the fuel saving can not be realized necessarily. The secondary release point suitable for the initial release airport refers to the distance from the secondary release point to the initial release airport, which is smaller than the distance from the secondary release point to the destination airport.
As shown in fig. 3, waypoint a is the closest waypoint on the way from the take-off airport to the destination airport at 87% of the forward range, i.e., the reference secondary release point. When the fuel oil allowance of the waypoint A does not meet the fuel oil demand of the airport of the initial destination, so that an alternative secondary release point-waypoint B before the waypoint A is selected on the route from the take-off airport to the final destination airport, and judging whether the airport suitable for the initial release is available or not again; if not, repeatedly executing the forward selection and judgment process on the alternative secondary release points until the alternative secondary release points are traversed. I.e. waypoints with a relative position of less than 70% are not taken as alternative secondary release points.
In an alternative embodiment, based on the initial airport releasing database of the route, judging the available state of the airport, and selecting the airport according to a specific rule to obtain the initial airport releasing; after the availability state of the airport is judged based on the initial release airport database of the route, the airport is selected according to a specific rule, and the fuel oil required for the selected route point to the initial release airport is calculated. The initial release airport is at least one airport for the aircraft to release secondarily in the secondary release flight plan, and the initial release airport database is an alternative airport set which is required to be prepared and maintained in advance for making the secondary release flight plan on the air route. Wherein, judge the usable state of airport, include: and judging whether the airport meets the landing requirement according to the airplane type, the meteorological conditions and the airspace conditions of the flight execution airplane. Optionally, the step of obtaining the first initial airport release comprises: determining available airports based on the airport availability status; the vertical distance from the route in the available airports is judged, and the nearest one is selected as the first initial airport release.
In an alternative embodiment, the method includes: when the initial release airport does not exist, determining the airport closest to the reference secondary release point as the first initial release airport from all airports meeting the landing condition; wherein the reference secondary release point is a waypoint with a relative position of 87%.
Optionally, the method further comprises: and when the secondary release points suitable for the current initial release airport do not exist, adjusting the current initial release airport to be the next initial release airport of the current initial release airport from all airports meeting the landing condition, so as to judge whether the secondary release points suitable for the initial release airport exist or not based on the next initial release airport and all the alternative secondary release points. And the like until determining that a secondary release point applicable to any one of the initial release airports exists, or determining that a secondary release point applicable to any one of the initial release airports does not exist.
In an alternative embodiment, during the flight of the aircraft at the take-off airport and the destination airport, determining each waypoint and the weight of the aircraft and the arrival time of the aircraft at each waypoint; determining meteorological data of each waypoint according to the arrival time of the aircraft at each waypoint, and determining dynamic performance data of the aircraft according to the data such as wind speed, wind temperature and the like in the meteorological data; determining fuel information of each waypoint according to the power performance data of the aircraft of each waypoint and the weight of the aircraft of each waypoint; correspondingly, based on the initial release airport and each alternative secondary release point, judging whether the secondary release point applicable to the initial release airport exists or not comprises the following steps: and acquiring fuel information of alternative secondary release points from the fuel information of each route point, and judging whether secondary release points suitable for the initial release airport exist or not according to the fuel information of the alternative secondary release points.
In an alternative embodiment, taking the fuel margin in the fuel information as an example to describe the secondary release points applicable to the initial release airport, determining whether the secondary release points applicable to the initial release airport exist based on the initial release airport and each alternative secondary release point includes: if the fuel oil allowance of the alternative secondary release point meets the fuel oil condition, the alternative secondary release point meets the secondary release point condition; and if the fuel oil allowance of the alternative secondary release point does not meet the fuel oil condition, the alternative secondary release point does not meet the secondary release point condition.
In an alternative embodiment, the fuel information is calculated sequentially, including but not limited to range oil, unexpected fuel, reserve oil, and last reserve oil. The fuel demand is a demand that meets the fuel demand specified by the relevant department.
In one exemplary embodiment, the fuel information includes a fuel margin and a unit fuel; determining fuel information of an alternative secondary release point comprises: acquiring the fuel oil allowance of an alternative secondary release point; according to the weight of the aircraft and the arrival time of the aircraft at the alternative secondary release points, determining the cruising performance data of the aircraft of each alternative secondary release point under the influence of meteorological data; according to the aircraft cruising performance data of each alternative secondary release point under the influence of meteorological data, determining unit fuel oil corresponding to each alternative secondary release point; determining the fuel oil demand from at least part of the alternative secondary release points to the initial release airport according to the unit fuel oil of each alternative secondary release point and the distance between the initial release airport and the alternative secondary release points; and judging whether a target secondary release point exists according to the fuel oil allowance and the fuel oil demand of the alternative secondary release point.
Wherein, judge whether there is the target secondary and release the point according to the fuel surplus and the fuel demand of alternative secondary and release the point, include: when an alternative secondary release point with the fuel oil allowance being larger than the fuel oil demand exists, the alternative secondary release point with the fuel oil allowance being larger than the fuel oil demand is taken as a target secondary release point; and when no alternative secondary release point with the fuel oil allowance being larger than the fuel oil demand exists, adjusting the initial release airport until all the initial release airports of the route are traversed.
Step 208, if the secondary release point suitable for the initial release airport exists, determining the secondary release point as a target secondary release point.
The target secondary release point is a secondary release point suitable for an initial release airport, when the target secondary release point exists in the alternative secondary release point, the backup oil carrying unexpected fuel oil and the like is calculated through the target secondary release point and the initial release airport suitable for the target secondary release point, so that the oil quantity carried by the aircraft in take-off is reduced, and the industrial load is increased.
In one embodiment, the method further comprises: determining a target secondary release point and an initial release airport suitable for the target secondary release point; determining a target oil quantity difference value based on the fuel oil allowance of the target secondary release point and the fuel oil demand between the target secondary release point and an initial release airport to which the target secondary release point is applicable; and determining the oil release condition corresponding to the target secondary release point according to the target oil quantity difference value.
The fuel oil allowance of the target secondary release point is the fuel oil amount still carried by the airplane after the airplane flies from the take-off airport to the target secondary release point; the fuel oil demand between the target secondary release point and the initial release airport suitable for the target secondary release point is the fuel oil required by the aircraft in the process of flying from the target secondary release point to the initial release airport suitable for the target secondary release point. In most cases, the fuel oil allowance of the target secondary release point is larger than the target fuel oil amount difference, and the two data can be in a relatively reasonable corresponding relation through the target fuel oil amount difference, so that the fuel oil amount is reduced as much as possible on the premise of ensuring safety.
Therefore, the target secondary release point capable of saving fuel is directly screened, the fuel allowance of the target secondary release point and the fuel demand of the initial release airport suitable for the target secondary release point are passed through, the target fuel quantity difference is calculated, and the unexpected fuel quantity is further reduced. After the unexpected oil quantity is reduced, the take-off weight of the aircraft is reduced, and the oil quantity of range oil carried by the aircraft in the take-off process and oil quantity of the final reserve oil are synchronously reduced, so that the oil quantity requirement in the oil quantity release condition corresponding to the target secondary release point is more in line with the actual condition, thereby saving fuel and improving the industrial load.
In one embodiment, if the target secondary release point does not exist, at least one secondary release point can be selected from the alternative secondary release points to generate a reference oil quantity difference value so as to reduce the oil quantity carried by the aircraft during take-off; correspondingly, the method further comprises the steps of: if no alternative secondary release points suitable for the initial release airport exist, calculating the fuel consumption between each alternative secondary release point and different initial release airports; screening the alternative secondary release points and the initial release airport according to the fuel consumption; determining a reference oil quantity difference value based on the screened fuel oil allowance of the secondary release point and the screened fuel oil demand between the secondary release point and the initial release airport; and determining the oil release condition from the take-off airport to the destination airport according to the reference oil quantity difference value.
In one exemplary embodiment, calculating fuel consumption between each alternate secondary release point and a different initial release airport includes: obtaining a first minimum fuel consumption from the first alternative secondary release point to the initial release airport based on the fuel consumption between the first alternative secondary release point and each initial release airport; obtaining a second minimum fuel consumption from the second alternative secondary release point to the initial release airport based on the fuel consumption between the second alternative secondary release point and each initial release airport; and taking the minimum oil consumption of the first minimum oil consumption and the second minimum oil consumption as the minimum oil consumption of the first alternative secondary release point and the second alternative secondary release point. The first alternative secondary release point and the second alternative secondary release point are any one or more alternative secondary release points.
In an alternative embodiment, as shown in FIG. 4, step 206 includes: screening out each alternative secondary release point and the fuel quantity of the aircraft at each alternative secondary release point from the fuel allowance of the aircraft at each route point; performing iterative calculation based on fuel oil demand of each secondary release at each alternative secondary release point and the initial release airport; correspondingly, step 208 includes: and finally, outputting the target secondary release point obtained by iterative computation.
Optionally, determining the fuel margin of the aircraft at each waypoint includes: based on the power performance data, meteorological data and route data of the aircraft, the weight, consumed fuel and time of the aircraft at each route point from the take-off airport to the final destination airport are calculated according to the minimum unpredictable fuel requirement. The power performance data of the aircraft are data which are improved by the manufacturer of the aircraft with the flight, including climbing, cruising, descending and waiting data, the meteorological data are global grid wind temperature data provided by a world area forecasting system, and the route data comprise route point coordinates and altitude data. The fuel balance is obtained by calculating the fuel quantity combination of the final reserve oil, the unexpected fuel of 15 minutes, the range oil and the like according to the specified fuel requirement and in sequence. Illustratively, determining the fuel margin of the aircraft at each waypoint includes: and (3) reversely pushing and calculating the aircraft from the final destination airport and the destination airport to the take-off airport in reverse order by route points to obtain take-off weight and the time of the aircraft passing through each route point, and consuming fuel oil and residual fuel oil. Among these, the minimum unpredictable fuel requirement is a requirement for unpredictable fuel in the CCAR121 section.
In the flight plan generation method, a plurality of waypoints between a take-off airport and a destination airport are acquired; and selecting alternative secondary release points from the plurality of route points according to the secondary release point conditions to form a range of target secondary release points, wherein the number of the alternative secondary release points in the range is excessive, and the secondary release points suitable for the initial release airport do not really exist, so that whether the secondary release points suitable for the initial release airport exist or not is judged based on the initial release airport and each alternative secondary release point, and the secondary release points suitable for the initial release airport are determined to be the target secondary release points. Therefore, whether the target secondary release point exists in the range of the alternative secondary release point is accurately determined, so that the oil quantity carried during take-off is determined according to the target secondary release point, and the effect of saving fuel is achieved. So as to reduce the carrying of unexpected fuel oil and other backup oil, further reduce the oil carried by the aircraft during take-off and increase the industrial load.
In one embodiment, as shown in fig. 5, based on the initial release airport and each alternative secondary release point, determining whether there is a secondary release point applicable to the initial release airport includes:
Step 502, determining the fuel condition that the alternative secondary release point reaches the initial release airport according to the distance between the alternative secondary release point and the initial release airport.
