Fatigue is recognised around the world as a serious safety implication for twenty-four hour operations. Operational requirements of an aviation medical transport service dictate service provision twenty-four hours a day.
Scientific research into fatigue and fatigue countermeasures in the past has taught us that in any twenty-four hour operation fatigue is a critical concern which can lead to catastrophic events, serious operational safety implications, significant decrements in alertness and performance, chronic sleep loss and disruption to circadian rhythms. Australian research into fatigue formed the basis for a parliamentary inquiry into managing fatigue in transport and compared the impairment on performance by fatigue as similar to the effects of moderate alcohol intoxication. Work periods longer than 10 to 12 hours are likely to impair wakefulness and performance and the impact of sleep inertia on safety.
This paper will investigate if we have learnt from our past in relation to fatigue research and will explore new innovations in fatigue management and fatigue countermeasures in the air medical environment.
