[0002] The restrictions contained in the corresponding retained item information in the aircraft's Minimum Equipment List (MEL) and Configuration Deviation List (CDL) concern aspects such as aviation safety, operational efficiency, customer service, and operating costs. However, when MEL / CDL restrictions are transferred between professional and technical personnel, such as pilots, flight dispatchers, and maintenance personnel, due to individual differences in the qualifications and job capabilities of these personnel, as well as flaws in the operational system and process design, the restrictions in the aircraft's Minimum Equipment List / CDL are prone to inadequate parsing and insufficient combined risk assessment, leading to irregular dispatch, flight delays, and passenger complaints. This results in currently inefficient dispatch and clearance, making it unable to meet the demands of real-time dynamic flight adjustments.

[0003] Therefore, how to solve the current low efficiency of dispatch and release has become a technical problem that needs to be solved urgently. Summary of the Invention

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0025] Those skilled in the art will understand that Figure 1 The hardware structure shown in the figure does not constitute a limitation on the computer device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0026] Continue to refer to Figure 1 , Figure 1 The memory 1005 as a computer-readable storage medium may include an operating system, a network communication module, and a digital application for the aircraft minimum equipment list and the aircraft configuration defect list.

[0027] exist Figure 1 In the embodiment, the network communication module is mainly used to connect to the server and perform data communication with the server; and the processor 1001 can call the digital application program of the aircraft minimum equipment list and the appearance defect list stored in the memory 1005, and execute the digital application method of the aircraft minimum equipment list and the appearance defect list provided in the embodiment of the present application.

[0028] An embodiment of the present application provides a digital application method for an aircraft minimum equipment list and an appearance defect list. The embodiment of the present application is described using a cleaning robot as a computer device.

[0029] Reference Figure 2 , Figure 2 This is a flow chart of the first embodiment of the digital application method for aircraft minimum equipment list and appearance defect list of this application.

[0030] In this embodiment, the digital application method of the aircraft minimum equipment list and the aircraft appearance defect list includes the following steps:

[0031] Step S210: upon receiving the reserved item information of the aircraft minimum equipment list / formal defects list, determining, based on the aircraft characteristic information of the target aircraft, the restriction item categories that affect the operation of the corresponding flight of the target aircraft and the specific restriction parameters corresponding to the restriction item categories in the reserved item information;

[0032] Currently, restrictions on the Minimum Equipment List / CDL (hereinafter referred to as MEL and CDL) affect aviation safety, operational efficiency, customer service, and operating costs. Information on MEL / CDL restrictions is typically circulated between three types of professional and technical personnel: pilots, flight dispatchers, and maintenance personnel. Considering individual differences in personnel qualifications and job capabilities, as well as design flaws in operating systems and processes, there are inadequate analysis of operating procedures and notes, and insufficient combined risk assessments. This can lead to issues such as illegal dispatch, flight delays, and passenger complaints. Furthermore, paper and electronic manuals are inefficient. Therefore, providing a digital application method for MEL / CDL restrictions has become an urgent issue in dispatch and release operations.

[0033] In order to solve the above problem, in this embodiment, the reserved item information is input and parsed. When the aircraft needs to apply for MEL / CDL retention due to equipment failure or external defects, the reserved item information (such as aircraft model, aircraft number, ATA chapter, and reservation terms) can be entered into the system by maintenance personnel or the system. The dispatch release system matches the preset MEL / CDL database according to the aircraft model, aircraft number and Air Transport Association (ATA) chapter, and automatically parses the impact category (such as safety and efficiency, cargo transportation) and specific restrictions (such as flight altitude ≤ FL250, prohibition of living things transportation) corresponding to the reserved items. For example, if the B737NG aircraft retains the air conditioning component according to MEL21-01-01-01, the system parses out that the flight altitude needs to be restricted to ≤ FL250, and is classified as a "safety and operation" impact category.

[0034] The IATA chapter is referred to below as the ATA chapter.

[0035] Step S220: verifying the flight operation parameters corresponding to the target aircraft based on the restriction item information and its corresponding specific restriction parameters;

[0036] In this embodiment, flight operation parameter matching and alarm verification are achieved based on the restriction item information and its corresponding specific restriction parameters. Specifically:

[0037] 1. First, parameter matching: The system verifies the MEL / CDL restrictions with the key parameters of the flight plan in real time, including but not limited to:

[0038] Flight altitude, route attributes (such as plateau airports), fuel quantity, crew configuration, cargo type, operating time (daytime / nighttime), etc.

[0039] Alarm triggering: If the parameters do not meet the limit requirements, the system triggers a graded alarm:

[0040] Level 1 Alert (critical violation): For example, if the flight's planned altitude is FL311 but the MEL limit is FL250, the system will automatically lock the dispatch release operation.

[0041] Level 2 alert (requires manual confirmation): For example, if a flight carries live animals but conflicts with reserved items, the cargo department will be prompted to coordinate with the passenger (shipper) to rebook.

[0042] For example, if the exhaust fan in the cargo hold of an A330 aircraft fails (MEL21-28-02A), the system detects that a live animal has been booked for transport and sends an alert to the dispatch and cargo departments, requesting a flight change or contacting the passenger (shipper).

[0043] Step S230: determining the guarantee unit associated with the restricted item information based on the association relationship between each reserved item and the guarantee unit, and determining the target customer associated with the restricted item information based on the association relationship between each reserved item and the customer;

[0044] In this embodiment, restriction item association and dynamic notification are performed. For example, the system automatically associates the relevant responsible units as associated guarantee units according to the restriction item type. For example:

[0045] Flight altitude restrictions: notify dispatch, flight, deployment, and intelligence departments;

[0046] Restrictions on the transportation of living animals: notify the freight, loading, ground service, marketing departments and passengers (shippers).

[0047] In a specific embodiment, real-time push can be further performed, that is, restriction information can be sent to related units through the system interface, for example:

[0048] Send a "no live animal transport" instruction to the cargo system and suspend live animal bookings on relevant flights;

[0049] Send or receive a "Flight Altitude Restriction" notification to the dispatcher, requiring adjustment of the enroute altitude level.

[0050] Step S240: Send the verification result corresponding to the flight operation parameter and / or the restricted item information to the support unit and / or target customer associated with the restricted item information.

[0051] In addition to sending the above information, this embodiment also includes automatically adjusting the flight plan and the Fielded Flight Plan Message (FPL) (hereinafter referred to as FPL message), specifically:

[0052] 1. Flight plan adjustment: The system automatically generates a compliant flight plan based on the restrictions:

[0053] 2. Flight altitude: Adjust to within the restricted range according to the route altitude layer allocation rules (e.g., from FL311 to FL246);

[0054] 3. Fuel quantity: Add a fixed value according to MEL requirements (e.g. add 2268kg of fuel if the main tank pump fails) or compensate for fuel consumption in proportion;

[0055] 4. Operation type: Limit PBN, ADS-B and other operational capabilities, and remove corresponding codes in FPL messages (such as deleting RNP AR codes).

[0056] 5. Dynamically generate FPL messages: The system automatically corrects the route altitude, operating capability and other fields in the navigation plan report to ensure that the message complies with the regulations of the authority.

[0057] This embodiment determines the restriction item categories based on the impact of the MEL / CDL reserved items on the corresponding flight operations of the target aircraft, that is, the impact categories of the MEL / CDL reserved items, including five categories: safety and efficiency, safety and benefits, safety and operation, cargo transportation, and service quality.

[0058] Collect and sort out the related guarantee units and related target customers of MEL / CDL retained projects, and determine the relationship between the restrictions involved in MEL / CDL retained projects and the guarantee units and customers.

[0059] Design the automatic parsing function of aircraft MEL / CDL reserved items. This function is when the system receives new aircraft reserved item information, the system automatically parses the restriction item information involved in the reserved item.

[0060] Design reminder and alert logic to link MEL / CDL reservations with flights. The system automatically analyzes restrictions on MEL / CDL reservations and notifies the associated support unit or target customer. The system also matches the MEL / CDL reservations with the aircraft's scheduled flights. If MEL / CDL requirements are not met, the system automatically issues an alert to the associated support unit or target customer.

[0061] An automated dispatch and release method is designed to adjust flight operation flight plans, FPL messages, etc. according to the requirements of the relevant restrictions of the MEL / CDL reserved items. When preparing the flight plan, the system first identifies whether the relevant restrictions of the MEL / CDL reserved items involve altitude restrictions, fuel adjustments, Performance-Based Navigation (PBN) operations (for example, PBN navigation must be used in plateau and complex terrain airspace, and PBN includes RNP APCH and RNP AR procedures, otherwise operations are prohibited, hereinafter abbreviated as PBN), Automatic Dependent Surveillance-Broadcast (ADS-B) operations, and automatically adjusts the flight plan elements such as altitude, fuel quantity, and operation type to meet the manual requirements.

[0062] The pilotage plan message is hereinafter abbreviated as FPL message, the performance-based navigation is hereinafter abbreviated as PBN, and the automatic dependent surveillance-broadcast is hereinafter abbreviated as ADS-B.

[0063] Therefore, this embodiment provides a digital application method for aircraft MEL / CDL. By automatically parsing the restrictive clause information of the MEL / CDL reserved items, the dispatch and release system automatically matches and notifies the associated support units and associated target customers. If the requirements are not met, the system automatically issues an alarm to the associated support units or associated target customers. The dispatch and release system automatically adjusts the flight plan altitude, fuel quantity, operating weight restrictions, and operation type to meet the requirements of regulations and manuals. This achieves efficient assessment of the MEL / CDL, enables the associated support units to quickly and accurately understand the impact of the MEL / CDL reserved items on operations, enhances emergency response capabilities, ensures daily operational safety, and reduces problems such as illegal dispatch, flight delays, and passenger complaints caused by the unreasonable handling of temporary MEL / CDL reserved items.

[0064] This embodiment provides a digital application method, device, and readable storage medium for an aircraft minimum equipment list and an external defect list. The method, upon receiving reserved item information of an aircraft minimum equipment list / external defect list, determines, based on aircraft characteristic information of a target aircraft, the categories of restricted items that affect the corresponding flight operations of the target aircraft and the specific restriction parameters corresponding to each restricted item category in the reserved item information; verifies the flight operation parameters corresponding to the target aircraft based on the restricted item information and its corresponding specific restriction parameters; determines the support unit associated with the restricted item information based on the association between each reserved item and a support unit, and determines the target customer associated with the restricted item information based on the association between each reserved item and a customer; and sends the verification results corresponding to the flight operation parameters and / or the restricted item information to the support unit and / or target customer associated with the restricted item information. Through the above method, this application parses the restriction clause information of the MEL / CDL reserved items to determine the restriction item categories that affect the corresponding flight operations of the target aircraft and the specific restriction parameters corresponding to each restriction item category, thereby realizing automatic verification of the flight operation parameters corresponding to the target aircraft and efficient evaluation of the MEL / CDL, enabling related support units to quickly and accurately obtain the impact of the MEL / CDL reserved items on flight operations, enhancing the emergency handling capabilities of flights, ensuring the daily operation safety of aircraft, and reducing problems such as illegal dispatch, flight delays, and passenger complaints caused by unreasonable handling of temporary MEL / CDL reserved items, thereby further solving the current problem of low dispatch and release efficiency.

[0065] In one embodiment, verifying the flight operating parameters corresponding to the target aircraft based on the restricted item information, and sending the verification results corresponding to the flight operating parameters and / or the restricted item information to the support unit and / or target customer associated with the restricted item information, includes:

[0066] Verifying flight operation parameters corresponding to the target aircraft based on the restriction item information, and determining whether the flight operation parameters meet restriction requirements corresponding to the restriction item information based on the verification result;

[0067] If the flight operation parameters do not meet the restriction requirements, generating warning information and warning levels according to the verification results;

[0068] Based on the alarm mode corresponding to the alarm level, the restricted item information and / or the alarm information is sent to the associated guarantee unit and / or the associated target customer corresponding to the restricted item category.

[0069] Exemplarily, after sending the restricted item information and / or the alarm information to the associated guarantee unit and / or associated target customer corresponding to the restricted item category based on the alarm mode corresponding to the alarm level, the method further includes:

[0070] Based on the specific restriction parameters corresponding to the restriction item category, the flight operation parameters in the flight operation plan of the target aircraft that do not meet the restriction requirements are adjusted, and the relevant parameters in the navigation plan message are corrected.

[0071] Exemplarily, adjusting the flight operation parameters in the flight operation plan of the target aircraft that do not meet the restriction requirements based on the specific restriction parameters corresponding to the restriction item category, and correcting relevant parameters in the navigation plan message, includes:

[0072] Based on the route altitude layer allocation rules, adjust the flight altitude in the flight operation plan to within the restricted range;

[0073] Based on the MEL requirements, the fuel quantity in the flight operation plan shall be increased by a fixed value or compensated for fuel consumption in proportion;

[0074] Generating a flight plan based on the modified flight operation plan to update the flight operation plan that does not meet the restriction requirements;

[0075] Correct the fields corresponding to the route altitude and the operation capability in the navigation plan report corresponding to the flight operation plan, and update the navigation plan report.

[0076] Exemplarily, before sending the restricted item information and / or the warning information to the associated guarantee unit and / or associated target customer corresponding to the restricted item category based on the warning mode corresponding to the warning level, the method further includes:

[0077] Determining an alert level corresponding to the flight operation parameter based on the number of parameters or the importance of the parameters of the flight operation parameter that do not meet the restriction requirements;

[0078] If the warning level is level 1, the dispatch release operation corresponding to the flight operation is terminated;

[0079] If the alert level is level 2, the dispatch release operation corresponding to the flight operation will be suspended, coordination work information will be sent to each related unit, and collaborative consultation reminder information will be sent to each target customer.

[0080] Exemplarily, before determining the guarantee unit associated with the restricted item information based on the association between each reserved item and the guarantee unit, and determining the target customer associated with the restricted item information based on the association between each reserved item and the customer, the method further includes:

[0081] According to the restricted item categories corresponding to each reserved item and the responsibilities of each guarantee unit, each reserved item is matched with each guarantee unit to obtain the association relationship between each reserved item and each guarantee unit;

[0082] According to the restricted item content corresponding to each reserved item and the tag information corresponding to each customer, each reserved item is matched with each customer to obtain the association relationship between each reserved item and each customer.

[0083] Among them, the aircraft characteristic information includes aircraft model, aircraft number and ATA chapter information, and the restriction item categories include safety and efficiency, safety and benefits, safety and operation, cargo transportation and service quality; the safety and efficiency includes the length of the flight segment, stopover time, number of flight segments and flight punctuality, etc.; the safety and benefits include take-off performance, route climb performance, landing performance, no-fuel weight limit, fuel balance, available load capacity and fuel quantity, etc.; the safety and operation includes landing standards, runway attributes, route / airport weather, navigation notices, airport support capabilities, route attributes, flight altitude, night flight operations, plateau / high plateau operations, special airports and special operations, extended range operations, polar operations and flight dynamic fixed telegram messages; the cargo transportation includes loading position, cargo attributes and transportation restrictions; the service quality includes living transportation, cabin service equipment, special passengers and cabin population.

[0084] In this embodiment, upon receiving the reserved item information of the aircraft minimum equipment list / formal defects list, based on the aircraft characteristic information of the target aircraft, the restricted item categories that affect the operation of the corresponding flight of the target aircraft and the specific restriction parameters corresponding to each restricted item category are determined in the reserved item information, including:

[0085] 1. Determine the impact category and restrictions of MEL / CDL reserved items based on their impact on flight operations.

[0086] 2. Collect the related guarantee units and related target customers of the restricted items, and determine the relationship between the restricted items and the guarantee units and related target customers.

[0087] Specifically, the support units and related target customers affected by the MEL / CDL retention project are sorted out, including dispatch, flight, deployment, aircraft performance, meteorology, intelligence, loading, airport ground operations, maintenance, ground services, cargo, service development, marketing, cabin, and passengers. The relationship between the 25 restrictions involved in the MEL / CDL retention project and the 15 support units and target customers is determined, such as Figure 3 As shown, the flight segment length restriction is associated with three support units: dispatch, flight, and allocation; the fuel quantity restriction is associated with two support units: dispatch and flight; the flight altitude restriction is associated with five support units: dispatch, flight, allocation, intelligence, and aircraft performance; the FPL message restriction is associated with three support units: dispatch, flight, and intelligence; the live animal transportation restriction is associated with seven support units: freight, loading, ground service, allocation, service development, marketing, and maintenance, and one support unit: target customer passenger; the PBN operation restriction is associated with four support units: dispatch, flight, allocation, and intelligence; the loading position restriction is associated with four support units: dispatch, freight, loading, and ground service; the daytime operation restriction is associated with three support units: dispatch, flight, and allocation, and so on.

[0088] 3. The system receives the new MEL / CDL reservation item of the aircraft and automatically parses the restriction information related to the MEL / CDL reservation item of the aircraft.

[0089] Specifically, an automated parsing function for aircraft MEL / CDL reservations was designed. A total of 3,527 reservation items (704, 1,584, and 1,239 items, respectively, requiring continuous updates) from the MEL / CDL manuals for the B737, A320, and A330 models were pre-organized, parsed, and integrated into the automated system. When the system receives new reservation information for an aircraft, it automatically matches the restrictions associated with the aircraft's MEL / CDL reservations based on the aircraft model, aircraft number, and ATA chapter.

[0090] 4. The system automatically matches and notifies the associated support unit or associated target customer of the restriction information related to the corresponding MEL / CDL reserved items.

[0091] Specifically, the restriction information related to the aircraft MEL / CDL reservation item analyzed in step 3 is used according to the association relationship between the restriction items and the support unit and the target customer determined in step S102 to determine the flight operation restriction information and push the restriction information to the corresponding support unit and target customer.

[0092] 5. The system matches and verifies the MEL / CDL reserved items with the aircraft's flight schedule. If the restrictions are not met, the system automatically issues an alert to the associated support unit or target customer.

[0093] Specifically, if Figure 4 As shown, the system matches the MEL / CDL retention information with the aircraft's flight plan altitude restrictions, route attributes, airport plateau / high altitude characteristics, operating time, airport support capabilities, cabin occupancy, and any live-animal transport restrictions. If restrictions are not met, the system automatically alerts the associated support unit or target customer. After the system alert is issued, the relevant support unit can adjust the flight route, delay the flight, reroute, change the crew, or restrict the transport of live animals to ensure that the aircraft meets the restrictions.

[0094] like Figure 5 As shown, after the passenger seats of a B737NG aircraft are fixed in the upright position according to MEL25-06-01A, the system automatically verifies whether the crew of the corresponding flight is an expanded crew and locks the seats. If it is a non-expanded crew, the flight can be carried out normally. If it is an expanded crew, the system will issue an alarm, and the flight planning and dispatching room will evaluate whether there are other available seats. If so, the flight can be carried out normally. If not, the flight planning and dispatching room will evaluate whether the flight can be changed to a non-expanded crew. If it can be changed, the flight can be carried out normally after the change. If it cannot be changed, it is necessary to coordinate in advance to downgrade passengers or make flight adjustments, etc., to ensure the normal operation of the flight.

[0095] like Figure 6 As shown, after an A330 aircraft retains the front cargo hold exhaust fan according to MEL21-28-02A, the system notifies cargo, ground service, service dispatch, marketing, loading, and allocation units that the aircraft restricts the transportation of living animals. After receiving the message, marketing and ground service will suspend the acceptance of passengers with pets on flights operated by the aircraft. At the same time, the system automatically verifies whether the flights operated by the aircraft have carried living animals. If so, the system will automatically trigger an alarm to allocation, ground service, service dispatch, marketing or cargo. After receiving the alarm, the allocation office will evaluate whether the flight can be adjusted. If not, the relevant units should contact the passengers or consignors as soon as possible after receiving the system alarm, inform them of the flight restriction information in advance, properly handle the demands of the passengers or consignors, and avoid public opinion incidents.

[0096] 6. When the dispatch release system releases a flight, it automatically adjusts the operational flight plan and FPL message based on the MEL / CDL reserved items.

[0097] Specifically, when the digital dispatch and release system prepares an operational flight plan, it first identifies whether the MEL / CDL restriction information involves operational restrictions such as flight plan altitude, fuel quantity / fuel consumption, PBN, ADS-B, etc.

[0098] like Figure 7 Regarding the handling of flight altitude restrictions, a B737NG aircraft retains the air conditioning component in accordance with MEL21-01-01-01. When preparing the operational flight plan, the digital dispatch release system verifies whether the route altitude restriction meets the requirement of being less than or equal to FL250. If not, the flight to be flown needs to be adjusted or the route needs to be changed to meet the requirement. When the flight to be flown meets the altitude restriction requirement, the system will automatically adjust the route altitude in the operational flight plan and FPL message according to the altitude layer allocation principle. Fuel adjustment includes three types: fixed increase in hourly fuel consumption, fuel consumption increase by ratio, and unusable fuel.

[0099] like Figure 8 Regarding the fuel quantity adjustment process shown in the figure, a B737NG aircraft retains the main tank fuel boost pump according to MEL28-01-03-01. The digital dispatch release system verifies the route attributes of the corresponding flight when preparing the flight plan. If the route attribute requirements are not met, the flight is adjusted to meet the route attribute restrictions. If the flight meets the route attribute restrictions, the system automatically adds 2268 kg of fuel to the flight plan's extra fuel when preparing the flight plan.

[0100] like Figure 9 Regarding the handling of operational restrictions such as PBN and ADS-B, a B737NG aircraft retains one takeoff / go-around switch in accordance with MEL22-17A. When preparing the flight plan, the digital dispatch and release system verifies whether the airport being operated requires Category II operations, RNP APCH, or RNP AR. If so, the flight being operated will be adjusted / delayed so that the flight does not operate Category II, RNP APCH, or RNP AR. At the same time, the system automatically deletes the corresponding code in item 18 when generating the FPL message.

[0101] Exemplarily, upon receiving the reserved item information of the aircraft minimum equipment list / formal defects list, before determining, based on the aircraft characteristic information of the target aircraft, the restriction item categories affecting the operation of the corresponding flight of the target aircraft and the specific restriction parameters corresponding to each restriction item category in the reserved item information, the method further includes:

[0102] When a reserved item information update instruction is received, the item update content in the reserved item information update instruction is converted into item information related to flight operations based on an item information conversion rule as the reserved item information.

[0103] In this embodiment, if the retention item information update instruction is "A certain A330 aircraft retains the front cargo hold exhaust fan in accordance with MEL21-28-02A", the item update content is converted from "Retain the front cargo hold exhaust fan" to "The aircraft restricts the transportation of living things"; if the retention item information update instruction is "A certain B737NG aircraft retains the air conditioning component in accordance with MEL21-01-01-01", the item update content is converted from "Retain the air conditioning component" to "Verify whether the route altitude restriction is less than or equal to FL250".

[0104] Specifically, historical dispatch release data can be analyzed to obtain conversion data of flight operation-related project information corresponding to the project update content in each update instruction, and based on the conversion data, project information conversion rules can be learned.

[0105] In further embodiments, when multiple restrictions exist simultaneously, the system further dynamically adjusts based on priority:

[0106] 1. Based on the principle of priority, safety restrictions (such as flight altitude and fuel consumption) take precedence over efficiency restrictions (such as flight duration) and service restrictions (such as transportation of living things).

[0107] 2. Based on the conflict resolution mechanism:

[0108] If adjusting the fuel causes overweight, and the flight altitude limit requires low-altitude flight (increased fuel consumption), the system will prioritize fuel safety and trigger flight load reduction or aircraft model change.

[0109] If PBN operation prohibition coexists with restrictions on the transportation of live animals, the system will generate independent alerts and manual assistance requests for coordinated and comprehensive processing by the dispatcher.

[0110] Furthermore, a secondary check is performed after the automated adjustment:

[0111] After the system completes the flight plan adjustment, it performs the following verification steps to ensure the plan is compliant:

[0112] 1. Regulatory compliance check: Compare the Civil Aviation Administration of China (CAAC) regulations and the company's operations manual to verify whether the flight plan parameters (such as fuel quantity and altitude) exceed the limit.

[0113] 2. Cross-departmental data synchronization: Automatically synchronize the adjusted flight plan to the flight, maintenance, ground service and other systems to ensure data consistency among departments.

[0114] 3. Simulation verification: Call the flight simulation interface to verify the feasibility of the adjusted plan (such as the meteorological risks of low-altitude flight routes).

[0115] In addition, an embodiment of the present application also provides a computer-readable storage medium.
