Utilizes engine manufacturers' assessment approach, calculates performance margins and incorporates the engine data analysis from I-Trend and I-Detect to create a health index. The health index provides a quantitative measure of the degradation of engine (or equipment) performance, pinpointing changes in each major engine component or module after its most recent flight. The index for each engine is aggregated to rank the fleet based on health. This visual ranking makes equipment maintenance, operations, and dispatch planning easier.; Utilizes engine manufacturers' assessment approach, calculates performance margins and incorporates the engine data analysis from I-Trend and I-Detect to create a health index.
