Fault Detection of Aircraft Piston Engine Based on Exhaustive Database Search

Modern aircraft piston engine monitor collects large amounts of data representing engine parameters. Data acquired during each flight is logged to a file. From the logs acquired during numerous previous flights a database of a healthy engine is formed containing feature vectors with selected engine parameters. Due to high speed processing of even modest microcontrollers, new feature vectors acquired during a flight can be compared in real time to all previous feature vectors stored in the database. Any significant discrepancy may indicate a problem in engine operation or engine fault. Such detection may alert a pilot and help prevent engine failure, partial loss of engine power or unplanned in-flight engine shutdown.
