<p>Sleep-related fatigue has negative effects on both human performance and decision making. Pilots are particularly  vulnerable to these adverse effects due to the environment and operational requirements, which entails both long and  irregular duty cycles.  The Air National Guard received funding from Office of the Secretary of Defense, Defense Safety Oversight  Council to create FlyAwake, a software application that predicts aircrew fatigue based on circadian cycles. FlyAwake  uses the Sleep, Activity, Fatigue, and Task Effectiveness (SAFTE) Model and calculates predicted effectiveness.  Recently, contract modifications have permitted integration with U.S. Navy's Sierra Hotel Aviation Readiness  Program (SHARP) as an Operational Risk Management (ORM) tool. Naval Aviation does not currently use fatigue  modeling as part of operational flight scheduling, and it is the intent of this thesis to provide a proof of concept  analysis of FlyAwake for Commander, Navy Air Forces (CNAF).  In order to validate FlyAwake, flight schedules from February 2008 were collected from the Helicopter  Antisubmarine Squadron Light Four Two (HSL-42) SHARP database. A statistical analysis compared fatigue levels  of aircrew using conventional scheduling methods against those with fatigue modeling, and showed improved fatiguebased  performance effectiveness with the utilization of FlyAwake.
