Pete Mellor <firstname.lastname@example.org> said: <Concorde stuff deleted> Every nut, bolt and washer must be traceable through all its moves between the various serials, and all their failures, inspections and repairs recorded. His sister works on the database which records all the parts and their movements. Apparently, it is *enormous* and requires the dedicated power of two large mainframes. Um, the major components are kept track of, but nuts, bolts, and washers are, according to standard practice in aircraft maintenance, discarded. There is no serial number tracking for expendables (when was the last time you saw a serial number on a washer?), but components which are re-used, such as pitot tubes and other repairables, are tracked by serial number. BTW, I would be surprised if the actual database required two mainframes for raw computing power -- more likely there are two mainframes to make sure the system is available worldwide to various maintenance stations 24 hours a day, every day. At the airlines I worked at, these computers did a LOT more than just parts tracking, such as aircraft scheduling and crew tracking. ed //////// Ed Hahn | email@example.com | (703) 883-5988 \\\\\\\\ The above comment reflects the opinions of the author, and does not constitute endorsement or implied warranty by the MITRE Corporation.
