Abstract:
1. A computer-implemented method for periodically monitoring performance of an engine in an aircraft during flight operations for predicting future engine problems, comprising: (a) receiving at a computer system engine performance data, environmental data, and flight data during use of the engine; (b) determining, using the computer system, if the engine is operating within a predetermined parameter set; (c) when the engine is operating within the predetermined parameter set and the aircraft is determined to be operating in a stable cruise regime, comparing, using the computer system, the engine performance data with previous engine performance data from at least one previous use of the same engine when the engine was operating within the predetermined parameter set taking into account the environmental data and flight data associated with the engine performance data and the previous engine performance data; (d) outputting, from the computer system, results of step (c); and (e) repeating steps (a) through (d) on successive flights of the aircraft.
