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

1 . A system for controlling an aircraft, comprising:
a memory; a processor disposed communication with said memory, said memory having instructions stored therein that, when read by said processor cause the processor to:
receive real-time aircraft data during aircraft flight;
process said real-time data to determine real-time aircraft mass data; and
calculate a real-time fuel mileage performance for the aircraft based upon determined aircraft mass data, wherein the real-time data comprises aircraft laden weight, thrust, drag, lift, speed, altitude, and atmospheric conditions that an aircraft is traveling through.

2 . The system of claim 1 , further comprising aircraft sensors that 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 . The system of claim 1 , wherein said instructions stored in memory further causes said processor to calculate a fuel mileage performance based on said mass data and at least one parameter from the group of parameters consisting of:
an environmental parameter, and a performance parameter, and wherein the performance parameter includes speed data, altitude data, temperature data, pressure data, and angle of attack data.

9 . A computer implemented method comprising:
receiving real-time data from aircraft sensors during aircraft flight; processing in a computer processor said real-time data to determine real-time aircraft mass data; and calculating real-time fuel mileage performance of the aircraft based on said determined aircraft mass data wherein the real-time data comprises aircraft laden weight, thrust, drag, lift, speed, altitude, and atmospheric conditions that an aircraft is traveling through.

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

11 . The method of claim 9 , further comprising transmitting a signal indicative of said fuel mileage performance to a cockpit of an aircraft.

12 . The method of claim 9 , further comprising adjusting an altitude and a cruise speed of said aircraft based on said calculated real-time fuel mileage performance.

13 . The method of claim 9 , 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.

14 . The method of claim 13 , 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.

15 . 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; process said real-time data to determine real-time aircraft mass data; and calculate real-time fuel mileage performance of the aircraft based on said determined aircraft mass data, wherein the real-time data comprises aircraft laden weight, thrust, drag, lift, speed, altitude, and atmospheric conditions that an aircraft is traveling through.

16 . A computer program product as recited in claim 15 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.

17 . A computer program product as recited in claim 15 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.

18 . A computer program product as recited in claim 15 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.

19 . A computer program product as recited in claim 15 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.
