Implementation of fatigue prediction models, such as the Sleep, Activity, Fatigue, and Task Effectiveness model, optimize scheduling by being able to predict pilot fatigue at any point in time. Although the mathematical model is limited by individual pilot differences it is the most accurate existing prediction because it takes into account ...
