Description

Technical Field

[0002] According to the Civil Aviation Administration of China's "Large Aircraft Public Air Transport Carrier Operation Certification Rules," aircraft must carry sufficient available fuel to safely complete the planned flight and make an emergency landing. The pre-flight calculation of the required available fuel must include discretionary fuel, which is additional fuel that the certificate holder decides to carry. This fuel is primarily based on additional fuel due to limiting factors such as weather and flow control. In existing technology, the amount of additional fuel carried by an aircraft is typically determined based on the dispatcher's subjective experience. Manual estimation methods can easily lead to large deviations in the amount of additional fuel carried by the aircraft. Excessive additional fuel carried by the aircraft can lead to "fuel consumption," while too little additional fuel carried by the aircraft may pose a safety risk of insufficient fuel for the flight.

[0042] Figure 2 The figure is a schematic diagram of the structure of the device for calculating the amount of fuel carried by an aircraft in an embodiment of the present invention. DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] See also Figure 1A first aspect of an embodiment of the present invention provides a method for calculating the amount of additional fuel carried by an aircraft, comprising the following steps S1 to S5:

[0045] Step S1, obtaining a number of historical flight data and constructing a data vector of each historical flight data;

[0046] Step S2, calculating the minimum additional fuel quantity corresponding to each historical flight based on the historical flight data;

[0047] Step S3, obtaining preset flight data of the flight to be processed, and constructing a data vector of the preset flight data;

[0048] Step S4, determining similar historical flights corresponding to the flight to be processed using a cosine similarity algorithm based on the data vectors of each historical flight data and the data vectors of the preset flight data;

[0049] Step S5: determining the target additional fuel quantity for the flight to be processed based on the minimum additional fuel quantity corresponding to the similar historical flights.

[0050] Specifically, this embodiment obtains a number of historical flight data and constructs corresponding data vectors. Then, based on the historical flight data, the minimum amount of additional fuel that should theoretically be carried on each historical flight is estimated. Furthermore, preset flight data of the flight to be processed is obtained and a corresponding data vector is constructed. Then, based on the data vectors of each historical flight data and the data vectors of the preset flight data, a cosine similarity algorithm is used to determine similar historical flights with similar operating conditions to the flight to be processed. The specific expression is as follows:

[0051]

[0052] Where A and B represent the data vector of historical flight data and the data vector of preset flight data, respectively. A smaller cosine value indicates a more similar operating condition between the historical flight and the flight to be processed. Furthermore, based on the minimum additional fuel allowance corresponding to similar historical flights, the target additional fuel allowance for the flight to be processed is determined. The flight data, historical additional fuel allowance, and target additional fuel allowance of the similar historical flight are then sent to the dispatcher for reference when preparing the flight plan.

[0053] As one preferred embodiment, in order to avoid the safety risk of insufficient fuel for a flight due to insufficient additional fuel, this embodiment selects three similar historical flights with the highest degree of similarity from a number of historical flights based on the cosine similarity calculation results between the data vectors of each historical flight data and the data vectors of the preset flight data. The target additional fuel amount for the flight to be processed is determined based on the maximum value of the minimum additional fuel amounts corresponding to the three similar historical flights.

[0054] As a preferred solution, the historical flight data includes at least aircraft status data, computer flight plan indicators and weather data of historical flights;

[0055] The step of constructing the data vector of each historical flight data specifically includes the following steps:

[0056] Assign values ​​to each weather condition based on the fuel consumption level corresponding to each weather condition, and numerically encode the weather data in each historical flight data according to the numerical value attached to each weather condition;

[0057] The aircraft status data, computer flight plan indicators and numerically coded weather data in each historical flight data are vector-joined to construct a data vector for each historical flight data.

[0058] Specifically, this embodiment obtains historical flight plans, QARs, weather data, and other data related to flight fuel consumption, including at least aircraft status data, computer flight plan indicators (flight altitude, flight segment distance, payload, alternate airport selection, etc.), and weather data (live weather reports and forecasts for takeoff and landing airports, and en-route weather). To construct data vectors for each historical flight data item, this embodiment digitizes unstructured data and numerically encodes character data. Specifically, based on the degree of fuel consumption corresponding to each weather condition (e.g., thunderstorms > continuous precipitation > showery precipitation > other weather phenomena > no special weather phenomena), each weather condition is ranked and assigned a value from highest to lowest in terms of fuel consumption. The weather data in each historical flight data item is numerically encoded according to the numerical value attached to each weather condition. If the weather data in the historical flight data item contains multiple weather conditions, only the weather condition with the highest fuel consumption is numerically encoded. Then, the aircraft status data, computer flight plan indicators and numerically coded weather data in each historical flight data are vector-joined to construct a data vector for each historical flight data.

[0059] As a preferred solution, the calculation of the minimum additional fuel quantity corresponding to each historical flight based on the plurality of historical flight data specifically includes the following steps:

[0060] Calculate the historical actual mileage fuel of each historical flight based on the historical take-off airport taxi-out remaining fuel, historical landing airport taxi-in remaining fuel, and historical taxiing fuel in the aircraft status data of each historical flight;

[0061] The minimum additional fuel carried corresponding to each historical flight is calculated based on the historical planned fuel, the historical unpredictable fuel and the historical actual fuel in the computer flight plan indicators of each historical flight.

[0062] Specifically, the formula for historical actual trip fuel is: Historical Actual Trip Fuel = Historical Departure Airport Taxi-Out Fuel - Historical Landing Airport Taxi-In Fuel - Historical Taxi Fuel. The formula for minimum additional fuel is: Minimum Additional Fuel = Historical Actual Trip Fuel - Historical Planned Trip Fuel - Historical Unforeseen Fuel. When the calculated minimum additional fuel is less than or equal to 0, the computer-calculated fuel estimate is sufficient, and no additional fuel is required. When the calculated minimum additional fuel is greater than 0, the computer-calculated fuel estimate is insufficient, and more additional fuel is required.

[0063] As a preferred solution, the preset flight data at least includes preset computer flight plan indicators and weather data of the flight to be processed;

[0064] The step of constructing the data vector of the preset flight data specifically includes the following steps:

[0065] Numerical coding is performed on the weather data in the preset flight data according to the numerical values ​​attached to each weather condition;

[0066] The preset computer flight plan indicators in the preset flight data and the weather data represented by numerical codes are vector-joined to construct a data vector of the preset flight data.

[0067] An embodiment of the present invention provides a method for calculating the additional fuel amount carried by an aircraft. The method calculates the minimum additional fuel amount carried by each historical flight using historical flight data and uses a cosine similarity algorithm to determine similar historical flights to the flight to be processed. This method can then reasonably determine the target additional fuel amount carried by the flight to be processed based on the minimum additional fuel amount carried by similar historical flights, thereby avoiding excessive deviation in the additional fuel amount carried.
