Claim Text:
1. A method for a computer-aided preparation of a failure tolerance report for a system of an aircraft comprising a plurality of subsystems, at least one subsystem of said plurality of subsystems having a computer processor and performing monitoring and notification of at least one detected event, the method comprising: implementing, via the computer processor, a critical event chart at least partially modelling said system, said critical event chart comprising a plurality of nodes, each node of said plurality of nodes being linked by a logical implication relation to at least one other node of said plurality of nodes, said plurality of nodes comprising: receiving, via the computer processor, at least one message notifying the occurrence of said at least one detected event, said detected event comprising said at least one node representing said critical event; creating, via the computer processor, a minimal diagnostic set relative to said at least one detected event, comprising a plurality of said elements suspected of resulting in said at least one detected event, each element of said minimal diagnostic set being represented by a node of said critical event chart and determined according to at least one logical implication relation of said critical event chart with said node representing said critical event associated with said at least one received notification message; selecting, via the computer processor, at least one receivable notification message represented by said node of said critical event chart; identifying, via the computer processor, elements of said minimal diagnostic set capable of resulting in the generation of said at least one selected notification message, said identified elements forming part of said failure tolerance report; and calculating a remaining distance before an imminent effect for at least one of said identified elements, said remaining distance being calculated as being equal to a number of the elements that do not form part of said minimal diagnostic set as said suspect candidate item, a malfunction of which being necessary for the generation of said at least one selected notification message.
