Abstract

Systems and methods for verifying that the flight crew has not made an error in entering takeoff flight performance data into the flight management system (FMS) using the electronic flight bag (EFB). The EFB includes a user interface that receives basic flight plan information and a processor. The processor automatically receives calculated takeoff performance data based on a previously entered basic flight plan, automatically receives user-entered takeoff performance data from a flight management system (FMS) located on a host aircraft, automatically compares the calculated takeoff performance data to the received takeoff performance data, and generates an entry error indication, if the comparison indicates that at least a portion of the entered takeoff performance data does not match the calculated takeoff performance data. An output device outputs the generated entry error indication.

Claims

1. A method comprising:

at a processor within an electronic flight bag (EFB),

automatically receiving calculated takeoff performance data from an On-board Performance Tool based on previously entered basic flight plan information;

automatically receiving user-entered takeoff performance data from a flight management system (FMS) located on a host aircraft;

automatically comparing the calculated takeoff performance data to the user-entered takeoff performance data; and

generating an entry error indication, if the comparison indicates that at least a portion of the user-entered takeoff performance data does not match the calculated takeoff performance data; and

at an output device associated with the EFB,

outputting the generated entry error indication.

2. The method of claim 1, further comprising:

at the processor, generating an on-board performance-tool image comprising the calculated takeoff performance data; and

at the output device, outputting the generated on-board performance-tool image;

wherein the outputted on-board performance-tool image includes the outputted entry error indication.

7. The method of claim 1, wherein outputting the generated entry error indication comprises causing an error message to be presented on a display of the EFB.

8. The method of claim 1, wherein the calculated takeoff performance data and the user-entered performance takeoff data comprises one or more of the group consisting of V-speeds, flap setting, takeoff thrust, weight, and center of gravity.

9. The method of claim 1, wherein the On-board Performance Tool calculates the calculated takeoff performance data based upon weather and runway condition information in addition to the previously entered basic flight plan information.

3. An electronic flight bag (EFB) apparatus comprising:

a processor configured to,

automatically receive calculated takeoff performance data from an On-board Performance Tool based on a previously entered basic flight plan;

automatically receive user-entered takeoff performance data from a flight management system (FMS) located on a host aircraft;

automatically compare the calculated takeoff performance data to the user-entered takeoff performance data; and

generate an entry error indication, if the comparison indicates that at least a portion of the user-entered takeoff performance data does not match the calculated takeoff performance data; and

an output device configured to output the generated entry error indication.

4. The apparatus of claim 3, wherein the processor is further configured to generate an on-board performance-tool image comprising the calculated takeoff performance data, wherein the output device is further configured to output the generated on-board performance-tool image, wherein the outputted on-board performance-tool image includes the outputted entry error indication.

10. The apparatus of claim 3, wherein, in outputting the generated entry error indication, the output device is configured to cause an error message to be presented on a display of the EFB.

11. The apparatus of claim 3, wherein the calculated takeoff performance data and the user-entered performance takeoff data comprises one or more of the group consisting of V-speeds, flap setting, takeoff thrust, weight, and center of gravity.

12. The apparatus of claim 3, wherein the On-board Performance Tool calculates the calculated takeoff performance data based upon weather and runway condition information in addition to the previously entered basic flight plan information.

5. A system comprising:

a means for automatically receiving calculated takeoff performance data, based on previously entered basic flight plan information;

a means for automatically receiving user-entered takeoff performance data from a flight management system (FMS) located on a host aircraft;

a means for automatically comparing the calculated takeoff performance data to the user-entered takeoff performance data;

a means for generating an entry error indication, if the comparison indicates that at least a portion of the user-entered takeoff performance data does not match the calculated takeoff performance data; and

a means for outputting the generated entry error indication.

6. The system of claim 5, further comprising:

a means for generating an on-board performance-tool image comprising the calculated takeoff performance data, wherein the means for outputting the generated entry error indication is further configured to output the entry error indication with the generated on-board performance-tool image.

13. The system of claim 5, wherein the means for outputting the generated entry error indication comprises a means for causing an error message to be presented on a display of the EFB.

14. The system of claim 5, wherein the calculated takeoff performance data and the user-entered performance takeoff data comprises one or more of the group consisting of V-speeds, flap setting, takeoff thrust, weight, and center of gravity.

15. The system of claim 5, wherein the calculated takeoff performance data is calculated based upon weather and runway condition information in addition to the previously entered basic flight plan information.
