Abstract:
A method for analyzing and recording information relating to the operation of a plurality of line replaceable units (LRUs) of an aircraft for subsequent fault analysis, said method comprising the steps of:a) monitoring and storing all available information generated by a plurality of LRUs relating to a plurality of operational parameters of said aircraft;b) determining if the information from a first one of said LRUs is of a magnitude which can be recorded in a memory map of an optical quick access recorder (OQAR);c) if said information from said first one of said LRUs cannot be recorded within said memory map, then overlaying a hierarchical level of information generated by said first one of said LRUs onto said memory map and determining if said hierarchical level of information fits within said memory map;d) if said hierarchical level of information still cannot be recorded onto said memory map, then overlaying said hierarchical level of information with information from a second LRU to produce a further condensed plurality of information and determining if said further condensed plurality of information from said first and second LRUs can be mapped in said memory of said OQAR; ande) if said further condensed plurality of information can be stored on said OQAR, then storing said further condensed plurality of information on said OQAR for subsequent analysis.
