Abstract

A device for processing faults, that detects and identifies faults, including, for at least part of the identified faults: a mechanism storing a log of occurrences of faults having a same identification, in a course of a plurality of flights; a mechanism determining an impact of each identified fault, on availability of aircraft in a predetermined duration, a mechanism associating a hierarchical attribute with each fault detected in a course of a flight, the hierarchical attribute being dependent on the log and on the impact; and a mechanism displaying identified faults associated with part of the hierarchical attributes. The device enables, in particular, maintenance operations or operations preparatory to maintenance to be better scheduled by virtue of hierarchization of faults displayed.

Claims

1. A device for processing failures, comprising:

circuitry configured to

receive data regarding detected and identified failures in a course of a flight of an airplane;

store a history of occurrences of failures having a same identification, in a course of a plurality of flights;

for each identified failure, determine status, ongoing or intermittent, based on the identified failure and stored history of occurrences of failures having the same identification as the identified failure, in a course of at least one preceding flight of the plurality of flights;

determine an impact of each identified failure on availability of the airplane in a predetermined period based on the determined status;

associate a hierarchical attribute with each failure detected and identified in the course of the flight, the hierarchical attribute being dependent on the history of occurrences of failures and the determined impact on availability of the airplane in the predetermined period; and

cause display of identified failures that are associated with a part of the hierarchical attributes.

2. A device according to claim 1, wherein the circuitry, which is configured to determine the status, ongoing or intermittent, of each identified failure, uses a category of each identified failure message.

3. A device according to claim 1, wherein the circuitry is configured to receive a history of occurrence of a failure from a tool on the ground, and to store the history.

4. A device according to claim 1, wherein the circuitry, which is configured to determine the impact of each identified failure on the availability of the airplane in the predetermined period, uses a category for each identified failure.

5. A device according to claim 1, wherein the circuitry, which is configured to associate a hierarchical attribute with each failure detected in the course of the flight, is adapted so that the hierarchical attribute is representative of failures having an impact that grounds the airplane, and to cause display the failures having the impact that grounds the airplane.

6. A device according to claim 1, wherein the circuitry, which is configured to associate a hierarchical attribute with each failure detected in the course of the flight, is adapted so that the hierarchical attribute is representative of failures having an impact that would ground the airplane if their status became ongoing in the predetermined period.

7. A device according to claim 1, wherein the circuitry, which is configured to associate a hierarchical attribute with each failure detected in the course of a flight, is adapted so that the hierarchical attribute is representative of failures occurring in the course of at least a first predetermined number of flights, among a second predetermined number of flights made by the airplane, and to cause display the failures.

8. A device according to claim 7, wherein at least one of the first and second predetermined numbers are dependent on the identification of the failure.

9. A device according to claim 1, wherein the circuitry, which is configured to associate a hierarchical attribute with each failure detected in the course of the flight, is adapted so that the hierarchical attribute is representative of failures capable, in combination with another failure not yet occurring, of grounding the airplane, and to cause display the failures.

10. A device according to claim 1, wherein the circuitry, which is configured to associate a hierarchical attribute with each failure detected in the course of a flight, is adapted so that the hierarchical attribute is representative of failures capable of grounding the airplane after a predetermined number of flying hours, and to cause display the failures.

11. An airplane, comprising the device according to claim 1.

12. A system for processing failures on the ground, comprising the device according to claim 1.

13. A method for processing failures detected and identified, the method comprising:

receiving, using a processor, data regarding detected and identified failures in a course of a flight of an airplane;

storing, using the processor, a history of occurrences of failures having a same identification, in a course of a plurality of flights;

for each identified failure, determine status, ongoing or intermittent, using the processor, based on the identified failure and stored history of occurrences of failures having the same identification as the identified failure, in a course of at least one preceding flight of the plurality of flights;

determining, using the processor, an impact of each identified failure on availability of the airplane in a predetermined period based on the determined status;

associating, using the processor, a hierarchical attribute with each failure detected and identified in the course of the flight, the hierarchical attribute being dependent on the history of occurrences of failures and the determined impact on availability of the airplane in the predetermined period; and

displaying identified failures that are associated with a part of the hierarchical attributes.
