Factors contributing to the risk of airline pilot and crew fatigue

The rhetoric that flight and ground crews are "tired" is taken lightly by some people unfamiliar with aviation. Every professional group has its own stress and fatigue and should be taken seriously; However, the importance we attach to the stress and fatigue of flight crews is that they are at critical points so that they can be the main actors in flight accidents. The concept of fatigue is often equated with muscle aches, loss of strength and decreased performance resulting from intense physical activity. This situation fits with the words "Tiredness" and "Exhaustion". However, within the concept of "Fatigue", there are also mental and psychological fatigue elements that are more important than fatigue and burnout. Their explicit and implicit consequences; carelessness, forgetfulness, timing and decision-making mistakes, intolerance, irritability, etc. A pilot or flight attendant cannot be expected to do a safe job if his/her body has not rested sufficiently, has not been able to get sleep and refresh his/her brain. Fatigue is the result of constant activities, insufficient rest, lack of sleep, and irregular work. The known consequences of fatigue are slowing down of reaction time, reduced attention and attention to details, difficulty in solving problems, lack of personal energy and motivation, communication problems, and inability to perform as required by the task.
