Abstract

A computer apparatus and method to determine aircraft fuel mileage performance. The computer apparatus including a memory and a processor disposed in communication with the memory and configured to issue a plurality of instructions stored in the memory. The instructions issue signals to receive real-time aircraft data during aircraft flight and process the real-time data to determine real-time aircraft mass data. A calculation is performed to determine the real-time fuel mileage performance for the aircraft based upon determined real-time aircraft mass data.

First claim

What is claimed is:

1. A system for controlling an aircraft, comprising:
aircraft sensors;
an aircraft interface device comprising an electronic flight bag (EFB) disposed in communication with the aircraft sensors, the EFB including:
a memory;
a display; and
a processor disposed in communication with said memory and display, said memory having instructions stored therein that, when read by said processor, cause the processor to:
receive real-time aircraft data from the aircraft sensors during aircraft flight;
process said real-time aircraft data to determine real-time aircraft mass data that accounts for weight decrease due to fuel burn over time;
calculate a real-time fuel mileage performance for the aircraft based upon determined aircraft mass data and at least one parameter selected from a group of parameters including an environmental parameter and a performance parameter including speed data, altitude data, temperature data, pressure data, and angle of attack data,
wherein the real-time data comprises aircraft laden weight, thrust, drag, lift, speed, altitude, and atmospheric conditions that an aircraft is traveling through; and
transmit the real-time fuel mileage performance to said display of the EFB.

2. The system of claim 1 , wherein said aircraft sensors transmit real-time data to said processor.

3. The system of claim 1 , wherein said real-time data is selected from a group consisting of: drag, lift, speed and altitude.

4. The system of claim 3 , wherein said instructions stored in memory further causes said processor to transmit an alert signal that indicates degradation of a fuel mileage performance.

5. The system of claim 3 , wherein said instructions stored in memory further causes said processor to transmit said fuel mileage performance to a cockpit of an aircraft.

6. The system of claim 3 , further comprising an aircraft having an altitude and a cruise speed, wherein said aircraft adjusts said altitude and said cruise speed based on said fuel mileage performance.

7. The system of claim 3 , wherein said processor calculates said fuel mileage performance based on said aircraft mass data, said system further comprising:
a database having records, and
wherein said memory further causes said processor to store said fuel mileage performance data as one record of said records in said database, and compare at least said one record to at least one previously stored record to yield performance trend data.

8. A computer implemented method, comprising:
receiving real-time data from aircraft sensors during aircraft flight at an electronic flight bag (EFB);
processing in a computer processor said real-time data to determine real-time aircraft mass data that accounts for weight decrease due to fuel burn over time;
calculating real-time fuel mileage performance of the aircraft based on said determined aircraft mass data and at least one parameter selected from a group of parameters including an environmental parameter and a performance parameter including speed data, altitude data, temperature data, pressure data, and angle of attack data,
wherein the real-time data comprises aircraft laden weight, thrust, drag, lift, speed, altitude, and atmospheric conditions that an aircraft is traveling through; and
transmit the real-time fuel mileage performance to a display of the EFB.

9. The method of claim 8 , further comprising transmitting an alert signal that indicates degradation of said fuel mileage performance when said fuel mileage performance is below a predetermined threshold.

10. The method of claim 8 , further comprising transmitting a signal indicative of said fuel mileage performance to a cockpit of an aircraft.

11. The method of claim 8 , further comprising adjusting an altitude and a cruise speed of said aircraft based on said calculated real-time fuel mileage performance.

12. The method of claim 8 , further comprising:
storing said fuel mileage performance as a record in a database having previously stored records; and
calculating a performance trend for said fuel mileage performance based on the record and at least one of the previously stored records.

13. The method of claim 12 , further comprising:
determining a degradation of fuel mileage performance according to the calculated performance trend; and
performing maintenance on the aircraft when the degradation of fuel mileage performance falls below a predetermined threshold.

14. A computer program product, comprising:
a non-transitory, machine-readable medium having instructions recorded thereon that, when read by a processor, cause the processor to:
receive real-time data from aircraft sensors during aircraft flight at an electronic flight bag (EFB);
process said real-time data to determine real-time aircraft mass data that accounts for weight decrease due to fuel burn over time;
calculate real-time fuel mileage performance of the aircraft based on said determined aircraft mass data and at least one parameter selected from a group of parameters including an environmental parameter and a performance parameter including speed data, altitude data, temperature data, pressure data, and angle of attack data,
wherein the real-time data comprises aircraft laden weight, thrust, drag, lift, speed, altitude, and atmospheric conditions that an aircraft is traveling through; and
transmit the real-time fuel mileage performance to the display of the EFB.

15. The computer program product as recited in claim 14 wherein said computer readable program code further causes the computer to transmit an alert signal that indicates degradation of said fuel mileage performance when said fuel mileage performance is below a predetermined threshold.

16. The computer program product as recited in claim 14 wherein said computer readable program code further causes the computer to adjust an altitude and a cruise speed of said aircraft based on said calculated real-time fuel mileage performance.

17. The computer program product as recited in claim 14 wherein said computer readable program code further causes the computer to:
store said fuel mileage performance as a record in a database having previously stored records; and
calculate a performance trend for said fuel mileage performance based on the record and at least one of the previously stored records.

18. The computer program product as recited in claim 14 wherein said computer readable program code further causes the computer to:
determine a degradation of fuel mileage performance according to the calculated performance trend; and
perform maintenance on the aircraft when the degradation of fuel mileage performance falls below a predetermined threshold.
