Abstract:

The US Army Research Laboratory ARL conducted a Design of Experiment study to assess the variability in health and usage monitoring systems and to reduce the effect of any bias that may result due to changes in pilots. The objective of the statistical approach is to support Sikorsky Aircraft in evaluating their flight regime recognition FRR algorithms with respect to pilot variability. Damage data collected by the FRR algorithms are being used to accurately determine usage credits. Variability is defined as the dispersion of the data, which could be caused by the pilots individual techniques. In this analysis, ARL has provided an additional approach for Health and Usage Monitoring Systems certification as a comparison to Aeronautical Design Standard Handbook for Condition Based Maintenance Systems for US Army Aircraft ADS-79D recommendations. The statistical analysis shows that the null hypothesis pilot variability did not influence regime recognition algorithms. There is a 95 confidence level that pilot variability is not an issue.
