Many of the exogenous contributors merit further study because they are present during transportation operations but not in most lab studies of fatigue. Fatigue can be a symptom of a medical problem, but more commonly it is a normal physiological reaction to exertion, lack of sleep, boredom, changes to sleep-wake schedules including jet lagor stress. Archived from the original on In the US, shift length is limited for nurses by federal regulation and some state laws. In addition to this, an FRMS may facilitate increased productivity and rostering flexibility. House of Representatives that pilot fatigue impacts aviation safety with "unknown magnitude". Fatigue is considered an internal precondition for unsafe acts because it negatively affects the human operator's internal state.
Fatigue is currently one of the hottest topic in transport safety research, since it has been recognized as one of the key factors in several.

5. Definition of acclimatised is an issue, as application and calculation is difficult.
A November report by the National Transportation Safety Board indicates that air crew fatigue is a much larger, and more widespread, problem than previously reported.
Fatigue can be a symptom of a medical problem, but more commonly it is a normal physiological reaction to exertion, lack of sleep, boredom, changes to sleep-wake schedules including jet lagor stress. A fatigue risk management system allows operators to effectively utilises their FTL Scheme whilst taking into account the above effects. The number of hours spent driving has a strong correlation to the number of fatigue-related accidents.
Physical fatigue is the inability to continue functioning at the level of one's normal abilities; a person with physical fatigue cannot lift as heavy a box or walk as far as he could if not fatigued. Archived from the original on Fatigue can be both physical and mental.


Historically, the aviation industry has taken a regulatory approach to fatigue prevention through the specification of flight and duty time limitations in a Flight Time Limitations FTL Scheme. The purpose of an FRMS is to support the safe application of such FTL Schemes by recognising the need for aircrew be adequately rested before commencing and during flying duties by facilitating both proactive and reactive interventions in relation to the implementation of FTL Schemes.
