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 ...
The fatigue must have lasted for 6 months or longer, and be present at least 50% of the time; Other symptoms are possible, such as muscle pain, mood problems, or sleep disturbance; Conditions known to cause severe fatigue and some mental conditions exclude a diagnosis.

The HADS is a 14-item scale, with seven items relating to anxiety and seven relating to depression. [2] Zigmond and Snaith created this outcome measure specifically to avoid reliance on aspects of these conditions that are also common somatic symptoms of illness, for example fatigue and insomnia or hypersomnia. This, it was hoped, would create ...
The International Follow-On Structural Fatigue Test Program (IFOSTP) was a joint venture between Australia, Canada and the U.S. to fatigue test the F/A-18 Hornet. The Australian test involved the use of electrodynamic shakers and pneumatic airbags to simulate high angle of attack buffet loads over the empennage .
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status and an abbreviated variant of it, the SF-6D, is commonly used in health economics as a variable in the quality-adjusted life year calculation to determine the cost-effectiveness of a health treatment.
