Abstract

Methods and systems for a flight deck display system for displaying text messages are provided. The system includes an alert generator configured to receive message signals from a plurality of aircraft systems and to generate alert messages based on the received message signals, and a flight deck display screen that includes a screen portion that is separately controlled by the alert generator to display messages received from the alert generator.

Claims

1. A flight deck display system for displaying text messages comprising:

an alert generator embedded in a memory and executed on a processing device, said alert generator configured to receive message signals from a plurality of aircraft systems and to generate alert messages based on the received message signals; and

a flight deck display screen comprising a first screen portion that is controlled by software associated with said display system and a second screen portion that is separately controlled by said alert generator to display messages received from said alert generator.

2. A system in accordance with claim 1 wherein said flight deck display screen forms a part of one or more flight deck displays.

3. A system in accordance with claim 1 wherein said alert generator includes logic rules, said alert generator configured to:

receive data inputs relating to the operation of airplane components and subsystems from airplane subsystems; and

generate message signals based on the received data inputs and the logic rules.

4. A system in accordance with claim 1 wherein said alert generator is configured to generate discrete alert signals to activate at least one of caution lights, warning lights, and aural messages based on the received data inputs and the logic rules.

5. A system in accordance with claim 1 wherein said alert generator is configured to generate textually formatted messages based on the received data inputs and the logic rules.

6. A system in accordance with claim 1 wherein said alert generator is communicatively coupled to said screen portion and other aircraft systems through a graphics generator configured to:

receive text message signals from said alert generator; and

generate graphics to cause text messages to be displayed on said screen portion.

7. A system in accordance with claim 6 wherein said graphics generator is configured to generate graphics to be displayed on one or more flight deck displays.

8. A system in accordance with claim 1 wherein said alert generator comprises at least one of a software code segment and a hardware module that is partitioned from a remainder of a central computing function of the aircraft.

9. A display system for an aircraft comprising:

an alert generator embedded in a memory and executed on a processing device, said alert generator configured to receive message signals from a plurality of aircraft systems and to generate alert messages based on the received message signals;

a flight deck display screen comprising a first screen portion that is controlled by software associated with said display system and a second screen portion that is separately controlled by said alert generator to display messages received from said alert generator; and

a software tool embodied on a separate computer communicatively couplable to said alert generator, said software tool configured to modify logic in said alert generator.

10. A system in accordance with claim 9 wherein said flight deck display screen forms a part of one or more flight deck displays.

11. A system in accordance with claim 9 wherein said alert generator includes logic rules, said software tool configured to:

receive a logic rule selection from user; and

associate a data input relating to the operation of airplane components and subsystems received by said alert generator with message signals to be displayed on said flight deck display screen based on a user input and the selected logic rule.

12. A system in accordance with claim 9 wherein said alert generator is configured to generate discrete alert signals to activate at least one of caution lights, warning lights, and aural messages based on the received data inputs and the logic rules.

13. A system in accordance with claim 9 wherein said alert generator is configured to generate textually formatted messages based on the received data inputs and the logic rules.

14. A system in accordance with claim 9 wherein said alert generator is communicatively coupled to said screen portion and other aircraft systems through a graphics generator configured to:

receive text message signals from said alert generator; and

generate graphics to cause the messages to be displayed on said screen portion.

15. A system in accordance with claim 14 wherein said graphics generator is configured to generate graphics to be displayed on one or more flight deck displays.

16. A system in accordance with claim 9 wherein said alert generator comprises at least one of a software code segment and a hardware module that is partitioned from a remainder of a central computing function of the aircraft.

17. A method of displaying messages on a flight deck display that includes a screen having a first portion controlled by the flight deck display and a second reserved portion of the screen controlled by a source external to the flight deck display, said method comprising:

receiving at least one input of a measured quantity from a plurality of airplane components and subsystems;

generating an alert signal using an alert generator, embedded in a memory and executed on a processing device, based on the at least one input and a predetermined logic rule, the alert generator including logic portioned from an airplane central computing function;

generating at least one text message based on the generated alert signal; and

transmitting the generated text message for display within the second reserved portion of the flight deck display screen.

18. A method in accordance with claim 17 further comprising determining a priority order of the at least one generated text message.

19. A method in accordance with claim 17 further comprising communicatively coupling the alert generator to a computer that includes a software tool embodied on a computer readable medium, the software tool programmed to receive inputs from a user to modify the predetermined logic rule such that a text message is generated based on the at least one input of a measured quantity and the modified logic rule.

20. A method in accordance with claim 17 further comprising qualifying the software tool by a regulatory body such that software modifications in the alert generator made using the software tool are certifiable by the regulatory body using less testing than software modifications in the alert generator made without using the software tool.
