Abstract
An aircraft engine diagnostic apparatus is described. The diagnostic apparatus senses engine performance related parameters refers the data to a standard atmosphere condition and plots values relating to the functions of each engine performance related parameter with respect to other engine performance related parameters. The apparatus compares these actual engine operating parameter values with standard baselines for normal engines and calculates the deviation between the actual curve and the standard curve as referred engine diagnostic data (REDD), an indicator of engine performance condition. The apparatus also senses the direction of deviation of the changing engine parameters from the standard baseline as an additional diagnostic indicator of the probable cause of engine deterioration. The deviation values are then instantaneously provided for immediate diagnosis of engine condition. A method of using the apparatus to diagnose engine problems is also described.
