Abstract

Claims (49)

1 . A system comprising:

a control unit configured to:

receive data regarding an aircraft, wherein the data comprises a cost index and a penalty factor, wherein the cost index is a numerical value used to balance fuel costs against time savings, and wherein the penalty factor is based on performance data of the aircraft, a route of the aircraft, a tail of the aircraft, a flight phase of the aircraft, and a gross weight of the aircraft; and

determine, based on the data comprising the cost index and the penalty factor, one or more economy speeds for the aircraft to fly between a departure airport and an arrival airport.

2 . The system of claim 1 , wherein the one or more economy speeds comprise a maximum economy speed, and a minimum economy speed.

3 . The system of claim 1 , wherein the data further comprises:

the performance data including information regarding operational capabilities of the aircraft, wherein the performance data is based on a generic performance model for a type of the aircraft, and historical data for the aircraft,

navigation data including information related to navigation of the aircraft in relation to one or more locations,

tracking data including information regarding a position of the aircraft within an airspace,

terrain data including information related to terrain at the one or more locations,

weather data including information regarding one or both of current weather or forecasted weather at the one or more locations,

flight plan data including information regarding one or both of a current flight plan or a future flight plan for the aircraft,

cost index data including information regarding a predetermined cost index for one or more flights of the aircraft, and

gross weight data including information regarding a gross weight of the aircraft.

4 . The system of claim 1 , further comprising a user interface including a display, wherein the control unit is in communication with the user interface, and wherein the control unit is further configured to show the one more economy speeds on the display.

5 . The system of claim 4 , wherein the control unit is further configured to show an economy speed graphic on the display.

6 . The system of claim 5 , wherein the control unit is further configured to show indicia on or within the economy speed graphic indicating that the aircraft is flying at the one or more economy speeds.

7 . The system of claim 4 , wherein the control unit is further configured to show, on the display, one or both of time saved or fuel saved from flying at the one or more economy speeds.

8 . The system of claim 1 , wherein the control unit is further configured to determine the one or more economy speeds in response to selection of an economy mode.

9 . The system of claim 1 , wherein the control unit is further configured to automatically operate the aircraft based on the one or more economy speeds.

10 . The system of claim 1 , wherein the control unit is an artificial intelligence or machine learning system.

11 . A method comprising:

receiving, by a control unit, data regarding an aircraft, wherein the data comprises a cost index and a penalty factor, wherein the cost index is a numerical value used to balance fuel costs against time savings, and wherein the penalty factor is based on performance data of the aircraft, a route of the aircraft, a tail of the aircraft, a flight phase of the aircraft, and a gross weight of the aircraft; and

determining, by the control unit, based on the data comprising the cost index and the penalty factor, one or more economy speeds for the aircraft to fly between a departure airport and an arrival airport.

12 . The method of claim 11 , wherein the one or more economy speeds comprise a maximum economy speed, and a minimum economy speed.

13 . The method of claim 11 , wherein the data comprises:

the performance data including information regarding operational capabilities of the aircraft, wherein the performance data is based on a generic performance model for a type of the aircraft, and historical data for the aircraft,

navigation data including information related to navigation of the aircraft in relation to one or more locations,

tracking data including information regarding a position of the aircraft within an airspace,

terrain data including information related to terrain at the one or more locations,

weather data including information regarding one or both of current weather or forecasted weather at the one or more locations,

flight plan data including information regarding one or both of a current flight plan or a future flight plan for the aircraft,

cost index data including information regarding a predetermined cost index for one or more flights of the aircraft, and

gross weight data including information regarding a gross weight of the aircraft.

14 . The method of claim 11 , further comprising showing, by the control unit, the one more economy speeds on a display of the user interface.

15 . The method of claim 14 , wherein said showing comprises:

showing, by the control unit, an economy speed graphic on the display; and

showing, by the control unit, indicia on or within the economy speed graphic indicating that the aircraft is flying at the one or more economy speeds.

16 . The method of claim 14 , wherein said showing further comprises showing, by the control unit, one or both of time saved or fuel saved from flying at the one or more economy speeds.

17 . The method of claim 11 , further comprising automatically operating the aircraft based on the one or more economy speeds.

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, to perform operations comprising:

receiving data regarding an aircraft, wherein the data comprises a cost index and a penalty factor, wherein the cost index is a numerical value used to balance fuel costs against time savings, and wherein the penalty factor is based on performance data of the aircraft, a route of the aircraft, a tail of the aircraft, a flight phase of the aircraft, and a gross weight of the aircraft; and

determining, based on the data comprising the cost index and the penalty factor, one or more economy speeds for the aircraft to fly between a departure airport and an arrival airport.

19 . The system of claim 2 , wherein the control unit is configured to:

determine the minimum economy speed by calculating a fuel mileage for a specific cost index, wherein a highest fuel mileage us computed as the minimum economy speed, and

determine the maximum economy speed by calculating a next set of economy speed based on the penalty factor in relation to fuel mileage.

20 . The method of claim 12 , wherein said determining comprises:

determining the minimum economy speed by calculating a fuel mileage for a specific cost index, wherein a highest fuel mileage us computed as the minimum economy speed, and

determining the maximum economy speed by calculating a next set of economy speed based on the penalty factor in relation to fuel mileage.
