Abstract

Disclosed is a computer-based electronic checklist system (10) that is interfaced with a crew alert system (12). The system provides both normal checklists (i.e., checklists for use during routine operation of the airplane) and non-normal checklists for use with crew alert messages that are supplied by the crew alert system. Non-normal checklists that are not associated crew alert messages are also provided. Status indicators are provided to indicate the completion state of non-normal checklists; the completion state of normal checklists, and, when applicable, the existence of a normal checklist that has not yet been used during that particular flight program. Checklist line items of each checklist are displayed in a manner that distinguishes between closed-loop items (i.e., checklist items for which the system operator need not respond); and open-loop line items (i.e., items requiring an operator response). Visual indication also is provided as to the completion state of each open-loop and closed-loop checklist line item. Accessing a desired normal or non-normal checklist is accomplished by using one of two command buttons (48 and 53). Operational notes encountered during operation of the system can be displayed at any time by actuating a single command button (52) and a system menu screen listing the normal and non-normal checklists is displayed by actuating a single command button (50).
