  • Method, devices and program for computer-aided analysis of the failure tolerance of an aircraft system, using critical event charts
    Patent number: 9266626
    Abstract: Aided analysis of the failure tolerance of an aircraft system, comprising a plurality of subsystems at least one of which comprises a monitoring unit and notification of a detected event, using critical event charts. After selecting at least one receivable notification message represented by a node of the critical event chart, elements of the minimal diagnostic set capable of resulting in the generation of the at least one selected notification message are identified, the identified elements forming part of the failure tolerance report.

  • Method, devices and computer program for assisting in the diagnostic of an aircraft system, using failure condition graphs
    Patent number: 8996340
    Abstract: A diagnostic system of an aircraft, comprising a plurality of sub-systems at least one of which performs monitoring and notification of at least one detected event, using graphs of feared events. After a message of notification of occurrence of the detected event has been received, a set of feared events linked to this message is created from the graph of feared events, and logic expressions are constructed according to logic links represented in the graph of feared events. A group of feared events then is created according to elements of the logic expressions. The minimal vertexes of the logic expressions associated with the feared events of the group are calculated and form a diagnosis of the system.

  • METHOD, DEVICES AND COMPUTER PROGRAM FOR ASSISTING IN THE DIAGNOSTIC OF AN AIRCRAFT SYSTEM, USING FAILURE CONDITION GRAPHS
    Publication number: 20120101793
    Abstract: The invention in particular has as an object aid in diagnosis of a system of an aircraft, comprising a plurality of sub-systems at least one of which comprises means for monitoring and notification of at least one detected event, using graphs of feared events. After a message of notification of occurrence of the said detected event has been received (500), a set of feared events linked to this message is created (510) from the said graph of feared events, and logic expressions—using as operands elements of the system coherent with the feared events of the said set—are constructed (515) according to the logic links represented in the said graph of feared events. A group of feared events then is created (520) according to elements of the said logic expressions. The minimal vertexes of the logic expressions associated with the feared events of the said group are calculated and form a diagnosis of the said system.
