Fatigue has long been identified as a human factor in aviation. Subsequently, series of studies have highlighted fatigue-related elements within the context aviation industry, focusing on flight deck – with some extension to students and maintenance activities. However, latter not deeply examined its crew-centered counterpart. Similarly if more significantly fatigue experienced by aircraft tech...

The current Air Force aircraft logistics system is reactive in nature, meaning that once a fault is detected, maintenance personnel must perform fault isolation procedures and then take steps to repair or replace the faulty item. The Autonomic Logistics System (ALS) concept changes this reactive process into a proactive one. This new approach to the logistics process shows the potential for cos...

The University of South Carolina has been involved in research for the US military for helicopters and rotary aircraft for over 18 years. Majority of this work has been focused on optimizing aircraft uptime and flight readiness by leveraging condition-based maintenance (CBM), more commonly known as predictive maintenance (PM). This type of maintenance differs from other classical styles (reacti...

This paper provides a lifecycle cost-benefit analysis of the use of Prognostics and Health Management (PHM) systems in future or present commercial aircraft. The approach considers individual aircraft component’s failure behavior, prognostic performance levels including prognostic errors, and condition-based maintenance (CBM) concepts. The proposed methodology is based on a discrete-event simul...
