 In early 2007, the 201 Airlift Squadron of the District of Columbia Air National Guard (ANG), successfully integrated its own version of the SAFTE simulation into its daily scheduling operations.This version was never validated against the original SAFTE simulation.This integration required the full-time attention of two pilot schedulers, but yielded valuable risk mitigation data that could be used by planners and leaders to predict and adjust critical times of fatigue in the flight schedule.
