US 9,540,117 B2 · Failure analysis system

Abstract

A failure analysis system for monitoring sub-system failures in an aircraft that comprises a plurality of sub-systems, the aircraft having a plurality of functions, wherein each function is available when one or more associated sub-systems is operating correctly. The failure analysis system comprising: a plurality of monitors for monitoring the status of one or more sub-systems of the aircraft and determining if a failure has occurred; a memory arranged to store a list of a plurality of flight phases or operating modes to be completed by the monitored system and data associating one or more of the functions with each flight phase or operating mode; and a processor in communication with the monitors and the memory and arranged to model the response of the sub-systems to a failure determined by the monitors to identify which functions required by the flight phases or operating modes are degraded or are not available.

Dependent claims

A failure analysis system for monitoring sub-system failures in an aircraft, the system comprising:

a plurality of monitors to monitor status of at least one sub-system of the aircraft, and to determine if a failure of at least one of the at least one sub-system has occurred;
a memory to store a list of a plurality of flight phases or operating modes to be completed by the at least one sub-system and to store data associating at least one function, which is associated with at least one of the at least one sub-system, with each of the flight phases or the operating modes;
and
a processor to communicate with the plurality of monitors and the memory, and to model a response of at least one of the at least one sub-system to a failure determined by the monitors to identify which of the at least one function required by the flight phases or the operating modes is degraded or is not available,
wherein when a plurality of the at least one function is not available, a human-computer interface produces an alert indicating that at least one of the at least one function associated with a next flight phase or operating mode is degraded or is not available.
