Description

Technical Field

[0001] The present invention relates to the technical field of civil aviation operation command, and particularly to a method, device, medium and equipment for managing the operation of cross-water flights. Background Art

[0002] When the flight route crosses a water area or ocean area, specific measures need to be taken to deal with the possible water landing situation of the aircraft in case of abnormal conditions. In this regard, the existing civil aviation regulations define cross-water operation and extended cross-water operation, and set the requirements to be met during such operations. Generally, cross-water operation refers to an operation where the horizontal distance of the aircraft from the nearest coastline exceeds the gliding distance of the aircraft.

[0003] The main basis for the existing technology to judge cross-water operation or extended cross-water operation is the distance of the aircraft from the nearest coastline. Although it is easy to understand, it does not meet the actual needs of front-line work. On the one hand, as the aircraft moves on the route, the position of the nearest coastline will also change, resulting in a complex calculation and determination process for cross-water operation or extended cross-water operation. On the other hand, the location of the nearest coastline does not necessarily represent a suitable landing site for the aircraft, and there is a large uncertainty. Assuming that the aircraft needs an emergency alternate landing during cross-water operation or extended cross-water operation, the existing technology fails to take into account the flight fuel consumption between the suitable alternate airport and the nearest coastline, making it difficult to meet the safety requirements.

[0077] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0078] An embodiment of the present invention provides a method for cross-water flight operation management. Refer to Figure 1 as shown, which is a schematic flowchart of the cross-water flight operation management method provided by an embodiment of the present invention in the first embodiment. The method includes steps S1 to S4:

[0079] Step S1, construct a flight operation database according to the acquired data;

[0080] Step S2, determine the cross-water operation route of the flight route according to the aircraft performance parameters in the flight operation database;

[0081] Step S3: Perform cross - water requirement detection on the airborne equipment, weather conditions, and flight fuel of the operating flights on the cross - water operation route;

[0082] Step S4: When the airborne equipment, weather conditions, and flight fuel of the operating flight all meet the corresponding detection standards, output the cross - water operation route with a passed performance evaluation.

[0083] When specifically implementing this embodiment, first construct a flight operation database according to the obtained data. To construct the flight operation database, refer to Figure 2 , which is a schematic structural diagram of the flight operation database provided by the embodiment of the present invention. The flight operation database specifically includes:

[0084] Flight plan database, including the departure airport, destination airport, alternate airport, departure time, destination time, estimated airborne time, and alternate airport.

[0085] Among them, Level1 is the departure airport, Level2 is the destination airport, Lvevl3 is the alternate airport, Level4 is the departure time, Level5 is the arrival time, Level6 is the estimated airborne time, and Level7 is the aircraft number and model.

[0086] Flight route, including the terminal procedure for approach and departure, waypoint, and airway.

[0087] Among them, Level8 is the departure airport, Level9 is the destination airport, Level10 is the terminal procedure for approach and departure, Level11 is the waypoint and coordinates, and Lvevl12 is the airway.

[0088] Aeronautical chart basic database, including aeronautical chart waypoints, aeronautical chart airways, the coordinate range and code of restricted areas in the aeronautical chart, the code of the coordinate range of dangerous areas in the aeronautical chart, airports, the runway number corresponding to each airport, and the approach and departure procedures corresponding to each airport.

[0089] Among them, Level13 is the aeronautical chart waypoint, Level14 is the aeronautical chart airway, Level15 is the coordinate range and code of restricted areas in the aeronautical chart, Level16 is the code of the coordinate range of dangerous areas in the aeronautical chart, Level17 is the airport, Level18 is the runway number corresponding to each airport, and Level19 is the approach and departure procedures corresponding to each airport.

[0090] Aircraft model database, where Level20 is the aircraft number and Level21 is the aircraft model and cross - water equipment.

[0091] Landing airport standards and weather database, where Level22 is the standard landing airport chart and coordinates, Level23 is the standard landing airport weather standards (RVR / VIS, DA / DH), and Level24 is the actual weather report (METAR) and weather forecast (TAF) of the standard landing airport weather report

[0092] The above information constitutes the database of the cross - water operation support safety management platform.

[0093] Determine the cross - water operation route of the flight route according to the aircraft performance parameters in the flight operation database.

[0094] The main purpose of cross - water operation and extended cross - water operation is to deal with the situation that "the aircraft may make a forced landing in water when an abnormal situation occurs". However, the existing technology mentions it in the regulations for cross - water operation requirements, but lacks further explanation; and a fixed value of 93 kilometers is directly set in the definition of extended cross - water operation, which is equivalent to believing that when the aircraft is more than this distance from the nearest coastline, the aircraft will make a forced landing in water in case of an abnormal situation. In fact, there are significant differences in the performance of different groups and models of aircraft. Taking the abnormal situation of one engine failure of an aircraft as an example, a narrow - body aircraft may have difficulty maintaining a flight of 93 kilometers to reach the nearest coastline, but for a large wide - body aircraft, its flight ability far exceeds 93 kilometers. And in actual operation, the aircraft performing extended cross - water operation on trans - oceanic routes are often wide - body aircraft.

[0095] When determining the cross - water operation route in this case, the performance differences of different aircraft are considered, and appropriate distance judgment methods and standards are proposed. The method of distinguishing cross - water operation aircraft according to specific performance requirements, the specific distance calculation method based on performance, and the determination process of the cross - water operation area or area combination based on performance.

[0096] After determining the cross - water operation route, detect the cross - water requirements of the operating flights on the cross - water operation route. If the route executed by the flight is a cross - water route, then judge whether the airborne equipment / weather standards / fuel for flight of the flight meet the cross - water requirements.

[0097] When the airborne equipment, weather conditions, and fuel for flight of the operating flight all meet the corresponding detection standards, output the cross - water operation route with a passed performance assessment, and plan a flight that meets the cross - water operation, then execute the flight operation model.

[0098] This case provides a safety management method based on cross-water operation support, which takes into account the performance differences of different aircraft, proposes appropriate distance judgment methods and standards, clarifies the onboard facilities and equipment, weather standards and aircraft fuel required to implement the cross-water operation, and provides better operational support and safety guarantees for aircraft to perform cross-water operations, which helps to reduce safety risks in flight operations, ensure the safety and normality of flights, and improve safety risk management capabilities.

[0099] In another embodiment provided by the present invention, the step S2 specifically includes:

[0100] Conduct flight performance evaluations of aircraft types for routes implementing cross-water route operations based on the flight routes described;

[0101] When the flight performance evaluation of the aircraft passes, and a certain waypoint on the flight route is more than a preset first threshold distance from an emergency landing airport that meets the preset emergency standard or a distance that the aircraft flies at a cruising speed for a preset first threshold time, the waypoint is determined to be a cross-water waypoint;

[0102] The union of the areas corresponding to all the cross-water waypoints is determined as the cross-water operation area, and the route of the flight route in the cross-water operation area is determined as the cross-water operation route.

[0103] In the specific implementation of this embodiment, a form of cross-water operation of a civil aircraft is defined as a performance-based cross-water operation, and a flight performance evaluation is performed on the aircraft type on the route implementing the cross-water route operation according to the flight route;

[0104] For aircraft that meet the performance requirements and implement cross-water route operations, if there is at least one waypoint on the route the aircraft plans to operate that is more than T1 minute of flight at cruising speed or L1 kilometer (whichever is less) away from an airport suitable for emergency landing, the area or combination of areas formed by the above waypoints is defined as a performance-based cross-water operation area, and the aircraft's flight in this area is defined as a performance-based cross-water operation.

[0105] As a preferred embodiment, T1 = 120, L1 = 720. In other embodiments, L1 and L2 may specifically adopt other values.

[0106] The area or area combination formed by the above waypoints is defined as the performance-based cross-water operation area, and the operation in this area belongs to the performance-based cross-water operation.

[0107] The route of the flight route in the cross-water operation area is determined as the cross-water operation route.

[0108] Determine that the flight route is a performance-based overwater operation route. If at least one point on the planned operating route of the target route is within the performance-based overwater operation area, then the target route is a performance-based overwater operation route. A specific performance-based overwater operation route is determined by the departure airport and the destination airport and the route between them. When it is determined that the target route is a performance-based overwater operation route, the operating requirements of the aircraft on the target route are implemented according to the provisions of the solution of the present invention. If the target route does not belong to the performance-based overwater operation route, the operating requirements of the aircraft on the target route are implemented according to the regulations of civil aviation for overwater operations.

[0109] In a performance-based overwater operation route, there may be one or more performance-based overwater operation segments. A performance-based overwater operation segment refers to the part of the planned route that is within the performance-based overwater operation area. Each performance-based overwater operation segment is determined by two suitable emergency landing airports before and after.

[0110] In a performance-based overwater operation route, the performance-based overwater operation entry point refers to the entry point on the performance-based overwater operation route where it enters the performance-based overwater operation segment.

[0111] In a performance-based overwater operation route, the performance-based overwater operation exit point refers to the exit point on the performance-based overwater operation route where it exits the performance-based overwater operation segment.

[0112] In another embodiment provided by the present invention, the step S2 specifically further includes:

[0113] When the flight performance evaluation of the aircraft fails, and a certain waypoint on the flight route is at a distance exceeding a preset second threshold distance from an emergency landing airport meeting the preset standard or the distance of the aircraft flying at the cruise speed for a preset second threshold time, determine that this waypoint is an overwater waypoint;

[0114] Wherein, the first ratio of the second threshold distance to the first threshold distance is equal to the second ratio of the second threshold time to the first threshold time, and is less than 1.

[0115] When specifically implementing this embodiment, refer to Figure 3 , which is another process schematic diagram of an overwater flight operation management method provided by an embodiment of the present invention. When the flight performance evaluation of the aircraft fails and all other aircraft meeting the performance requirements perform overwater waypoint operations, if there is at least one waypoint on the planned operating route of the aircraft at a distance exceeding the distance of flying at the cruise speed for T2 minutes or L2 kilometers (100 nautical miles) (whichever is less) from a suitable emergency landing airport.

[0116] The area or combination of areas formed by the above waypoints is defined as a performance-based over-water operation area, and the operation in this area belongs to performance-based over-water operation.

[0117] As an embodiment, T1 / T2 = 4, L1 / L2 = 4. In other embodiments, other values can be specifically adopted for L2 and T2.

[0118] In another embodiment provided by the present invention, the flight performance of the aircraft type on the route for implementing over-water route operation is evaluated according to the flight route, including:

[0119] When the flight route uses a twin-engine aircraft and an engine fails at any point on the flight route, if the gliding distance of the aircraft is greater than the distance to the standard landing airport and the flight altitude at any position is not lower than the minimum flight altitude, it is determined that the flight performance evaluation of the aircraft passes;

[0120] When the flight route uses a three-engine aircraft and two engines fail at any point on the flight route, if the gliding distance of the aircraft is greater than the distance to the standard landing airport and the flight altitude at any position is not lower than the minimum flight altitude, it is determined that the flight performance evaluation of the aircraft passes.

[0121] In the specific implementation of this embodiment, when performing performance evaluation, for a twin-engine aircraft, when an engine fails at any point on the planned operation route or the planned diversion route, it can still fly to the standard landing airport and the flight altitude at any point is not lower than the minimum flight altitude.

[0122] For an aircraft with three or more engines, the flight in any flight segment on the planned operation route or the planned diversion route needs to meet the requirements of the above twin-engine aircraft; if the relationship between the location of the standard landing airport and the total flight duration causes the possibility of a second engine failure to be considered in order to maintain the expected overall safety level, then the aircraft must be able to continue flying to the standard landing airport and land when two engines fail, that is, when two engines fail at any point on the flight route, if the gliding distance of the aircraft is greater than the distance to the standard landing airport and the flight altitude at any position is not lower than the minimum flight altitude, it is determined that the flight performance evaluation of the aircraft passes.

[0123] Specifically, the emergency criteria include: the minimum weather conditions of the en-route alternate airport and the minimum operating conditions of the en-route alternate airport.

[0124] An emergency landing airport suitable for use is an airport that is listed in the operating specifications of the airline approved by the Civil Aviation Administration and, considering the conditions of the airport at that time, is expected to be available for use as an alternate landing for over-water operations during dispatch or flight release, and is the designated alternate airport on the route specified during dispatch or flight release. Among them, the consideration of the conditions of the airport at that time means that within the time period when the aircraft is expected to arrive, the conditions of the airport meet the following:

[0125] There is a corresponding weather report or forecast, or a combination of both, indicating that the weather conditions at the airport are equal to or higher than the minimum weather standards for alternate airports on the route specified in the airline's operating specifications;

[0126] The surface condition report of the airport indicates that the aircraft can make a safe landing.

[0127] The standard landing airport refers to an optional alternate airport on the route that is listed in the airline's operating specifications regardless of the conditions at that time. It may be one of the following two types of airports: a civil airport suitable for the operation of the aircraft in use, where the airport must be able to provide rescue and firefighting services matching the level of the aircraft in use; an available military airport open to civil use.

[0128] In another embodiment provided by the present invention, the method further includes:

[0129] When the on-board equipment, weather conditions, or flight fuel of the operating flight on the over-water operation route do not meet the corresponding detection standards, the original flight route is disassembled into several segments with a preset splitting distance as the radius;

[0130] Determine whether there is an airport in the area to which each segment belongs that meets the airports in the standard landing airport database;

[0131] If so, proceed to the next segment for judgment;

[0132] If not, use the Dijksrta algorithm to search and select all waypoints within the splitting distance range from the chart basic database to the standard landing airport to traverse all waypoints within the entire range, find the shortest path route, replace the segment, and update the flight route.

[0133] When performing the detection of on-board equipment, weather conditions, and flight fuel, if the route executed by the flight is an over-water route, determine whether the corresponding on-board equipment / weather standard / flight fuel of the flight meets the over-water requirements. If not, based on the original planned route, disassemble the original route into segments 1, 2, 3...n with a radius of 720 km;

[0134] Determine whether there is an airport in the standard landing airport database within the area of each 720 km segment;

[0135] If so, proceed to the next paragraph for judgment. When there is no standard landing airport within a 720-km area, find the standard landing airport closest to the flight segment. Use the Dijksrta algorithm to search and select the air routes within a radius of 720 km from the standard landing airport based on the basic flight chart database, traverse all waypoints within the entire range, find the shortest path route to generate the air route plan, plan a route that meets the overwater operation requirements, and update the flight route.

[0136] Generate a route that meets the overwater requirements based on the aircraft performance under the original flight route. If a flight that meets the overwater operation requirements is planned, execute the flight operation model.

[0137] In another embodiment provided by the present invention, step S3 specifically includes:

[0138] Obtain the airborne equipment data of the operating flight on the overwater operation route;

[0139] When the airborne equipment data does not include an underwater positioning device, or the underwater positioning device is in an abnormal state, or the underwater positioning device is configured on the wing or tail, it is determined that the airborne equipment of the operating flight on the overwater operation route does not meet the safety assessment requirements;

[0140] When the airborne equipment data includes a normally operating underwater positioning device and the underwater positioning device is not configured on the wing or tail, monitor the operation of the overwater equipment system through multiple edge computing nodes arranged on the aircraft, and output the evaluation result of the airborne equipment according to the monitoring results;

[0141] Obtain the weather data of the operating flight on the overwater operation route;

[0142] When, after the aircraft passes through the overwater operation route, the weather conditions of the designated alternate airport do not meet the minimum standards for landing operations, it is determined that the weather state does not meet the corresponding detection standards;
