Diagnostics for aircraft

摘要

A system for automatically analysing aircraft systems data is described. The system comprises a data acquisition module operable to acquire aircraft systems data, a data archiving module operable to store aircraft systems data and a data analysis module operable to analyse the aircraft systems data to identify non-predetermined troubleshooting procedures for fault rectification. Automated identification of improved maintenance techniques can thus be provided, with the added benefit that maintenance manuals and procedures may thereby be automatically adapted over time. A related method is also described.

1. A system for automatically analysing aircraft systems data, comprising:
a data monitor operable to detect data packets transmitted over an aircraft data bus including built-in test data that identifies aircraft faults; a data acquisition module operable to acquire aircraft systems data including data related to predetermined troubleshooting procedures; an on-board maintenance system that captures aircraft configuration data including data related to changes made to the aircraft; a data analysis module operable to identify a performed troubleshooting procedure based on the aircraft configuration data, execute a correlation test comparing the performed troubleshooting procedure to the predetermined troubleshooting procedures, identify based on the correlation test that the performed troubleshooting procedure is a non-predetermined troubleshooting procedure for fault rectification, and update the aircraft systems data to include the non-predetermined troubleshooting procedure, wherein the non-predetermined troubleshooting procedure includes a set of performed fault rectification actions.
