Abstract

A system includes one or more control units configured to determine one or more fuel consumption models for an aircraft. A method includes determining, by one or more control units, one or more fuel consumption models for an aircraft. A non-transitory computer-readable storage medium comprising executable instructions that, in response to execution, cause one or more control units comprising a processor, to perform operations including determining one or more fuel consumption models for an aircraft.

First claim

What is claimed is:

1. A system comprising:
one or more control units disposed onboard an aircraft and configured to obtain predicted fuel consumption data for a flight of the aircraft, wherein the predicted fuel consumption data predicts consumption of fuel by the aircraft over time during the flight prior to the aircraft consuming the fuel, the one or more control units configured to communicate the predicted fuel consumption data to a ground-based sub-system,
wherein, during the flight, the one or more control units are configured to determine actual fuel consumption data of the aircraft via one or more fuel sensors onboard the aircraft, and to compare the actual fuel consumption data to the predicted fuel consumption data,
wherein, responsive to a difference between the actual fuel consumption data and the predicted fuel consumption data being greater than a predetermined tolerance, the one or more control units are configured to communicate an update signal from the aircraft to the ground-based sub-system, the update signal including a value of the actual fuel consumption data.

2. The system of claim 1 , wherein the one or more control units are configured to obtain a performance model for the aircraft, the performance model configured to generate the predicted fuel consumption data for the flight of the aircraft.

3. The system of claim 2 , wherein the one or more control units are configured to obtain the predicted fuel consumption data for the flight of the aircraft by inputting initial conditions for the aircraft before the flight and real time data of the aircraft during the flight into the performance model.

4. The system of claim 3 , wherein the performance model is based on at least one of Quick Access Record (QAR) data or continuous parameter logging (CPL) data.

5. The system of claim 3 , wherein the one or more control units are configured to generate the performance model to be specific to the aircraft using historical data of the aircraft.

6. The system of claim 3 , wherein the initial conditions comprise payload of the aircraft, total fuel onboard the aircraft, a center of gravity of the aircraft, and weather conditions for the flight of the aircraft.

7. The system of claim 1 , wherein the one or more control units are configured to update a fuel consumption model, that outputs the predicted fuel consumption data, based on the value of the actual fuel consumption data so that the predicted fuel consumption data output by the fuel consumption model conforms to the actual fuel consumption data.

8. The system of claim 1 , further comprising one or more user interfaces including a display and an input device, wherein the one or more control units are configured to show the predicted fuel consumption data on the display.

9. The system of claim 1 , wherein the one or more control units are further configured to automatically modify at least one of an airspeed or an altitude of the aircraft based on the difference between the actual fuel consumption data and the predicted fuel consumption data.

10. The system of claim 1 , wherein the one or more control units comprise an artificial intelligence or machine learning system.

11. The system of claim 1 , wherein, responsive to the difference between the actual fuel consumption data and the predicted fuel consumption data not being greater than the predetermined tolerance, the one or more control units are configured to determine that the predicted fuel consumption data is accurate and not communicate the update signal to the ground-based sub-system.

12. A method comprising:
obtaining, by one or more control units disposed onboard an aircraft, predicted fuel consumption data for a flight of the aircraft, wherein the predicted fuel consumption data predicts consumption of fuel by the aircraft over time during the flight prior to the aircraft consuming the fuel;
communicating the predicted fuel consumption data to a ground-based sub-system;
determining actual fuel consumption data of the aircraft during the flight via one or more fuel sensors onboard the aircraft;
comparing, via the one or more control units, the actual fuel consumption data to the predicted fuel consumption data;
in response to a difference between the actual fuel consumption data and the predicted fuel consumption data being greater than a predetermined tolerance, communicating an update signal from the aircraft to the ground-based sub-system, the update signal including a value of the actual fuel consumption data; and
in response to the difference between the actual fuel consumption data and the predicted fuel consumption data not being greater than the predetermined tolerance, determining that the predicted fuel consumption data is accurate and not communicating the update signal to the ground-based sub-system.

13. The method of claim 12 , wherein the one or more control units are configured to obtain the predicted fuel consumption data by inputting initial conditions for the aircraft before the flight and real time data of the aircraft during the flight into a performance model that is specific to the aircraft.

14. The method of claim 13 , further comprising generating the performance model, via the one or more control units, to be specific to the aircraft using historical data of the aircraft.

15. The method of claim 13 , wherein the initial conditions comprise payload of the aircraft, total fuel onboard the aircraft, a center of gravity of the aircraft, and weather conditions for the flight of the aircraft.

16. The method of claim 12 , further comprising automatically modifying, by the one or more control units, at least one of an airspeed or an altitude of the aircraft based on the difference between the actual fuel consumption data and the predicted fuel consumption data.

17. The method of claim 12 , further comprising updating a fuel consumption model based on the value of the actual fuel consumption data, the fuel consumption model configured to output the predicted fuel consumption data, wherein the fuel consumption model is updated so that subsequent predicted fuel consumption data output by the fuel consumption model conforms to the actual fuel consumption data.

18. A non-transitory computer-readable storage medium comprising executable instructions that, in response to execution, cause one or more control units comprising a processor and disposed onboard an aircraft, to perform operations comprising:
determining predicted fuel consumption data for a flight of the aircraft, wherein said predicted fuel consumption data is determined by inputting initial conditions for the aircraft before the flight and real time data of the aircraft during the flight into a performance model that is specific to the aircraft, wherein the predicted fuel consumption data predicts consumption of fuel by the aircraft over time during the flight prior to the aircraft consuming the fuel;
communicating the predicted fuel consumption data to a ground-based sub-system;
determining actual fuel consumption data of the aircraft during the flight via one or more fuel sensors onboard the aircraft;
comparing the actual fuel consumption data to the predicted fuel consumption data;
in response to a difference between the actual fuel consumption data and the predicted fuel consumption data being greater than a predetermined tolerance, communicating an update signal from the aircraft to the ground-based sub-system, the update signal including a value of the actual fuel consumption data; and
in response to the difference between the actual fuel consumption data
