System for creating a single electronic checklist in response to multiple faults
First Claim
1. A computer-based method of producing a single electronic checklist in response to two or more faults detected by an aircraft sensing system and transmitted on an aircraft data bus, the method being performed by an electronic checklist system of the type that can monitor the aircraft data bus and display one or more action items to be performed by a pilot or crew in response to an aircraft fault, the method comprising the steps of:
- monitoring the aircraft data bus for two or more fault codes that are produced by the aircraft sensing system when the aircraft sensing system detects two or more faults;
reading the fault codes from the aircraft data bus when the faults have been detected;
determining a number of action items to be performed by the pilot or crew in response to each fault code read from the data bus;
placing the number of action items into a single list, each action item having associated with it a priority code;
executing one or more priority rules associated with each fault code, which cause the electronic checklist system to evaluate one or more operating characteristics of the aircraft;
sorting the action items in the angle list by the priority codes and the operating characteristics of the aircraft; and
displaying the single list of action items to the pilot and crew.

Abstract
A computer-based electronic checklist system automatically generates a single electronic checklist upon the detection of two or more control system faults. The checklist contains a plurality of notes to be read by, and action items to be performed by, the operator. The system combines a set of predefined action items for each fault and executes a set of conditional rules that modify the action items to reflect the current state of the control system. The system then executes a set of priority rules to determine the correct order in which the action items of the checklist are to be performed. Once the correct order of the action items is determined, the system executes a set of conflict rules to remove any conflicting or redundant action items in order to provide the operator with a single electronic checklist that is customized to the control system'"'"'s current operating condition.

8. An electronic checklist system for producing a single electronic checklist in response to two or more system faults detected by a fault sensing system, the checklist including one or more action items to be performed in response to a fault, the system comprising:
-
means for detecting two or more fault codes that are produced by the fault sensing system when the fault sensing system detects two or more faults; means for reading the fault codes from the fault sensing system when the faults have been detected; means for determining a number of action items to be performed in response to each fault code read; means for placing a number of action items into a single list, wherein each action item has associated with it at least one priority code; means for executing one or more priority rules that cause the electronic checklist system to evaluate one or more operating characteristics of the system and to modify the priority codes of the action items based on the operating characteristics of the system; means for sorting the action items in the single list by the priority codes; and means for displaying the single list of action items. - View Dependent Claims (9, 10, 11, 12)
