Engine fault detection for piston engine aircraft

Digital engine monitor can record vast amount of data in form of engine parameters from the aircraft piston engine. By analyzing these parameters it should be possible to detect majority of current or impeding engine problems. Statistical description of engine parameters together with rule based pattern recognition of catalogued graphic engine fault patterns shown as bar graphs on the engine monitor display may help detect abnormal engine conditions. Method for automatic analysis of engine monitor data and labeling potential problems is described.
