Method of and system for presenting an operating status of an aircraft engine

1. A computer-implemented system for presenting an operating status of an aircraft engine, the system comprising:

a non-transitory computer-readable medium;

a processor configured to perform:

determining, by the processing unit, that an aircraft engine start switch is on an “on” position;

determining, by the processing unit, that a healthy start of the aircraft engine is occurring based on an analysis of a first data indicative of an exhaust gas temperature of a combustion chamber of the aircraft engine and a second data indicative of a rotation speed of the aircraft engine; and

causing the display of a first visual indication indicative of the determined healthy start of the aircraft engine.

2. The system of claim 1 , wherein the processor is further configured to perform:

determining, by the processing unit, that an abnormal start of the aircraft engine is occurring based on the analysis of the first data and the second data; and

causing to replace the first visual indication with a second visual indication indicative of the determined abnormal start of the aircraft engine.

3. The system of claim 1 , wherein the analysis of the first data and the second data comprises comparing the first data with a first model and the second data with a second model, the first model defining an acceptable behaviour of a variation of the exhaust gas temperature of the combustion chamber of the aircraft engine and the second model defining an acceptable behaviour of a variation of the rotation speed of the aircraft engine.

4. The system of claim 1 , wherein the first visual indication is caused to be displayed for a period of time extending from a beginning of a start of the aircraft engine to an idle operating mode of the aircraft engine.

5. The system of claim 1 , wherein causing the display of the first visual indication is independent of a displaying of operating parameter values of the aircraft engine.

6. A computer-implemented system for presenting an operating status of an aircraft engine, the system comprising:

a non-transitory computer-readable medium;

a processor configured to perform:

causing the display of a first visual indication indicative of a healthy start of the aircraft engine as a result of a detection, by the processing unit, that a command to start the aircraft engine has been issued;

after a period of time has lapsed, accessing, from the non-transitory computer-readable medium, an indication indicative of an aircraft engine start operating mode, the indication having been generated based on an analysis of a parameter associated with an operating condition of the aircraft engine;

upon determining, by the processing unit, based on the indication, that the aircraft engine start operating mode is a healthy start:

maintaining the display of the first visual indication; and

upon determining, by the processing unit, based on the indication, that the aircraft engine start operating mode is an abnormal start:

causing to replace the display of the first visual indication by the display of a second visual indication indicative of the abnormal start of the aircraft engine.

7. The system of claim 6 , wherein the period of time comprises a first period of time and a second period of time, the first period of time starting at the issuance of the command to start the aircraft engine and ending at an ignition of the aircraft engine and the second period of time starting at the ignition of the aircraft engine and ending at a predefined amount of time.

8. The system of claim 6 , wherein the analysis of the parameter associated with the operating condition of the aircraft engine comprises comparing the parameter with a predefined threshold and wherein the abnormal start is determined to be the aircraft engine operating mode if the parameter does not exceed the predefined threshold during the period of time.

9. The system of claim 6 , wherein the analysis of the parameter associated with the operating condition of the aircraft engine comprises comparing the parameter with a predefined threshold and wherein the healthy start is determined to be the aircraft engine operating mode if the parameter exceeds the predefined threshold during the first period of time.

10. The system of claim 7 , wherein the predefined amount of time ranges from 3 seconds to 90 seconds.

11. The system of claim 6 , wherein the period of time ranges from 3 seconds to 90 seconds.

12. The system of claim 6 , the processor being further configured to perform, prior to causing the display of the first visual indication indicative of the healthy start of the aircraft engine:

accessing, from the non-transitory computer-readable medium, a second indication indicative of a position of an aircraft engine start switch.

13. The system of claim 12 , wherein the detection, by the processing unit, that the command to start the aircraft engine has been issued comprises determining, by the processing unit, based on the second indication, that the position of the aircraft engine start switch is an “on” position.

14. The system of claim 12 , the processor being further configured to perform:

upon determining, by the processing unit, that a command to stop the aircraft engine has been issued:

causing to stop the display of the first visual indication.

15. The system of claim 14 , wherein determining, by the processing unit, that the command to stop the aircraft engine has been issued comprises determining, by the processing unit, based on the second indication, that the position of the aircraft engine start switch is an “off” position.

16. The system of claim 6 , wherein causing the display of the first visual indication is independent of a displaying of operating parameter values of the aircraft engine.

17. The system of claim 6 , wherein a reading, by a user, of the first visual indication allows establishing that the healthy start of the aircraft engine is occurring without requiring the reading of operating parameter values of the aircraft engine.

18. The system of claim 6 , wherein a reading, by a user, of the second visual indication allows establishing that the abnormal start of the aircraft engine is occurring without requiring the reading of operating parameter values of the aircraft engine.

19. The system of claim 6 , wherein the analysis of the parameter associated with the operating condition of the aircraft engine has been performed after the predetermined period of time has lapsed.

20. A computer-implemented system for presenting an operating status of an aircraft engine, the system comprising:

a non-transitory computer-readable medium;

a processor configured to perform:

accessing, from the non-transitory computer-readable medium, a first indication indicative of a position of an aircraft engine start switch;

accessing, from the non-transitory computer-readable medium, a second indication indicative of an aircraft engine start operating mode, the second indication having been generated based on an analysis of a parameter associated with an operating condition of the aircraft engine;

upon determining, by the processing unit, based on the first indication and the second indication, that the position of the aircraft engine start switch is an “on” position and the aircraft engine start operating mode is a healthy start:

causing the display of a first visual indication indicative of the healthy start of the aircraft engine; and

upon determining, by the processing unit, based on the first indication and the second indication, that the position of the aircraft engine start switch is an “on” position and the aircraft engine start operating mode is an abnormal start:

causing the display of a second visual indication indicative of the abnormal start of the aircraft engine.
