Adaptive algorithm-based engine health prediction

A method of reflecting recent corrected engine performance in a data storage device on an aircraft, the method comprising, by a computer comprising a processor and memory:

• receiving, from an engine sensor coupled to the computer, engine operating information for an engine on the aircraft;
• determining, from the engine operating information, a power parameter and a critical parameter,
• correcting the power parameter and the critical parameter based on additional information available in an aircraft data bus on the aircraft;
• recording, as a data point in a stored data set in the data storage device, the corrected power parameter and the corrected critical parameter;
• grouping the data point with statistically similar historical data points in the stored data set;
• merging the data point and the statistically similar historical data points into a single representative data point in the stored data set, the stored data set including previously recorded power parameter and critical parameter data points;
• and
• purging one or more older data points in the stored data set.

A computer system comprising a processor and memory, wherein the processor and the memory in combination implement a method of reflecting recent corrected engine performance in a data storage device on an aircraft, the method comprising:
