  • Diagnostic trend analysis
    Patent number: 5951611
    Abstract: A diagnostic trend analysis method is used to analyze engine trend data for aircraft engines. Appropriate trend parameters are calculated from raw trend data and wild points associated with the calculated trend parameters are eliminated. Abnormal shifts and changes are detected at the most recent point for each trend parameter. The abnormal shifts and changes in each trend parameter are then evaluated. The evaluation is used to filter out spurious symptoms and provide accurate maintenance recommendations for real engine trend shifts.
