Abstract

A cloud-based computing system for providing a maintenance message associated with a unique maintenance action for fault rectification is disclosed. The system includes a diagnostic module including one or more processors configured by instructions stored in non-transient computer readable media. The diagnostic module is configured to: identify, for each potential CAS message in an aircraft, a set of inputs that are evaluated to trigger the potential CAS message; identify, for each of the potential CAS messages, each unique combination of input conditions for the set of inputs that triggers the potential CAS message; and identify, for each of the potential CAS messages, a unique maintenance message associated with each unique combination of input conditions that triggers the potential CAS message, wherein each unique maintenance message is associated with a unique maintenance action for fault rectification.

Claims

1. A computer-implemented method in a cloud-based computing system for providing maintenance assistance to aircraft maintenance personnel, the method comprising:

receiving, by a processor in the computing system, a crew alerting system (CAS) message that is displayed to aircrew on an aircraft;

identifying, by the processor, a set of inputs that may trigger the CAS message;

identifying, by the processor, the condition of each input in the set of the inputs;

identifying, by the processor based on the condition of each input in the set of the inputs, a maintenance message associated with the CAS message that identifies a unique maintenance action for fault rectification for the CAS message.

2. The method of claim 1, wherein identifying a set of inputs that may trigger the CAS message comprises invoking a diagnostic module that is configured, for each potential CAS message in the aircraft, to identify the set of inputs that are evaluated to trigger the CAS message and configured to identify, for each of the potential CAS messages, the unique combination of input conditions that triggers the CAS message.

3. The method of claim 2, wherein the diagnostic module is configured to identify the logic applied to the set of inputs to set the CAS message to identify the unique combination of input conditions that triggers the CAS message.

4. The method of claim 2, wherein the diagnostic module is configured to apply machine learning techniques to identify the unique combination of input conditions that triggers the CAS message.

5. The method of claim 1, further comprising generating a diagnostic module configured to:

identify, for each potential CAS message in an aircraft, a set of inputs that are evaluated to trigger the potential CAS message;

identify, for each of the potential CAS messages, each unique combination of input conditions for the set of inputs that triggers the potential CAS message; and

identify, for each of the potential CAS messages, a unique maintenance message associated with each unique combination of input conditions that triggers the potential CAS message, wherein each unique maintenance message is associated with a unique maintenance action for fault rectification.

6. The method of claim 1, wherein identifying a maintenance message comprises identifying a unique combination of input conditions that triggered the CAS message.

7. The method of claim 6, wherein identifying a maintenance message comprises identifying the unique maintenance message associated with the unique combination of input conditions that triggered the CAS message.

8. The method of claim 1, wherein identifying the condition of each input in the set of the inputs comprises receiving aircraft bus data from the aircraft.

9. The method of claim 1, wherein receiving a CAS message comprises receiving a query from a user device regarding the status of aircraft health.

10. The method of claim 1, further comprising receiving, by the processor, a query from a user device regarding the status of aircraft health.

11. The method of claim 10, further comprising responding to the query by providing, by the processor to the user device, the maintenance message associated with the CAS message that identifies the unique maintenance action for fault rectification for the CAS message.

12. A cloud-based computing system for providing a maintenance message associated with a unique maintenance action for fault rectification for a CAS message, the system comprising:
