HSI Lessons Learned from 10 years of UAS Operation
This study was a 10-year cross-sectional analysis of human factors in U.S. military UAV mishaps. Methods: Class A-C UAV mishap reports were reviewed and human factors coded using the Human Factors Analysis and Classification System (HFACS). HFACS codes were linked to human systems integration (HSI) domains. Conclusion: Recurring latent failures at the organizational, supervisory, and preconditions levels contributed to more than half of UAV mishaps. The patterns of latent failures and unsafe acts differed between the services. HSI issues pertaining to the human factors domain were common to all services.
