Abstract

A method of managing alerts associated with the operation of an aircraft is provided. The method maintains an alert model database that correlates root causes to alerts associated with onboard aircraft subsystems. During operation of the aircraft, the method receives first alert data indicative of at least one alert of a first onboard aircraft subsystem, and traverses the alert model database to determine a root cause of the first alert data. The root cause (or some indicia thereof) can then be displayed on a display element.

Claims

1. A method of managing alerts associated with the operation of an aircraft, the method comprising:

receiving alert messages indicative of predefined alerts for a plurality of different onboard aircraft subsystems, each of the onboard aircraft subsystems having a set of predefined alerts that can be active or inactive at any given point in time, and each of the alert messages indicating active or inactive status of one of the predefined alerts;

processing active alerts identified in the received alert messages;

determining an originating cause of the active alerts in response to the processing;

presenting indicia of the originating cause in a human-understandable format;

filtering the received alert messages to obtain a reduced number of received alert messages; and

rendering the reduced number of received alert messages on a flight deck display element.

2. The method of claim 1, wherein receiving alert messages comprises receiving alert messages that convey contextual information related to the alerts.

3. The method of claim 1, wherein determining the originating cause comprises:

accessing an alert model database that indicates cascading relationships between active alerts;

identifying, from the received alert messages, a cascaded alert; and

traversing the alert model database to find a parent alert from which the cascaded alert originated, wherein the originating cause is related to the parent alert.

4. The method of claim 1, wherein determining the originating cause comprises:

accessing an alert model database that indicates relationships between originating causes and patterns of active alerts that originate from a plurality of different onboard aircraft subsystems;

identifying, from the received alert messages, a pattern of active alerts; and

traversing the alert model database to find a relationship between the pattern of active alerts and the originating cause.

5. The method of claim 1, wherein:

the received alert messages include time stamp information for the active alerts; and

determining the originating cause is influenced at least in part by the time stamp information.

6. The method of claim 1, further comprising:

obtaining a recommended response to the originating cause; and

presenting indicia of the recommended response in a human-understandable format.

7. The method of claim 6, wherein presenting indicia of the recommended response comprises displaying indicia of the recommended response on the flight deck display element.

8. The method of claim 6, wherein obtaining the recommended response comprises:

accessing a response database that correlates originating causes to recommended responses; and

retrieving, from the response database, the recommended response based upon the originating cause.

9. A method of managing alerts associated with the operation of a vehicle, the method comprising:

maintaining an alert model database that correlates root causes to alerts associated with subsystems onboard the vehicle;

receiving a plurality of alert messages from the subsystems onboard the vehicle;

traversing the alert model database to determine a root cause of the plurality of alert messages;

displaying indicia of the root cause on a display element;

filtering the received alert messages to obtain a reduced number of received alert messages; and

rendering the reduced number of received alert messages on the display element.

10. The method of claim 9, wherein:

the alert model database includes an alert cascade dataset that indicates cascading relationships between alerts of a first subsystem onboard the vehicle;

the traversing step traverses the alert cascade dataset to find a parent alert from which the plurality of alert messages originated; and

the root cause is related to the parent alert.

11. The method of claim 9, further comprising:

determining a recommended response to the root cause; and

displaying indicia of the recommended response on the display element.

12. The method of claim 11, wherein determining the recommended response comprises:

traversing a response database that correlates root causes to recommended responses; and

retrieving, from the response database, the recommended response based upon the root cause.

13. A system for managing alerts associated with the operation of an aircraft, the system comprising:

a processing architecture configured to carry out processor-executable instructions;

a processor-readable medium accessible by the processing architecture; and

processor-executable instructions stored on the processor-readable medium, wherein, when executed by the processor architecture, the processor-executable instructions cause the processor architecture to carry out a method comprising;

receiving a plurality of alert messages from a first onboard aircraft subsystem and a second onboard aircraft subsystem;

analyzing the received alert messages to determine a common cause of the alert messages; and

obtaining a recommended response to the common cause;

filtering the received alert messages to obtain a reduced number of received alert messages; and

rendering the reduced number of received alert messages on a display element of the aircraft.

14. The system of claim 13, further comprising an alert model database accessible by the processing architecture, wherein the alert model database correlates root causes to alerts associated with onboard aircraft subsystems, and wherein analyzing the received alert messages comprises accessing the alert model database to identify the common cause based upon the received alert messages.

15. The system of claim 14, wherein:

the alert model database includes an alert cascade dataset that indicates cascading relationships between alerts of the first onboard aircraft subsystem and the second onboard aircraft subsystem; and

the common cause corresponds to a parent alert from which the plurality of alert messages originated.

16. The system of claim 14, wherein the alert model database is an airframe-specific loadable database.

17. The system of claim 13, further comprising a response database accessible by the processing architecture, wherein the response database correlates root causes to recommended responses, and wherein obtaining the recommended response comprises accessing the response database to identify the recommended response based upon the common cause.

18. The system of claim 17, wherein the response database is an airframe-specific loadable database.
