Which factor is a leading cause of pilot fatigue?

Lack of proper rest is recognized as a leading cause of pilot fatigue because it directly impacts cognitive functioning, decision-making skills, and overall physical readiness to perform flight tasks. When a pilot does not get sufficient restorative sleep, it not only leads to drowsiness but also affects critical abilities such as attention, reaction time, and judgment, which are essential for safe flying.

In aviation, where maintaining alertness and focus is crucial, insufficient rest can quickly translate into performance deficits that pose risks during flight operations. Understanding the impact of sleep and fatigue management is essential for pilots to ensure their well-being and the safety of their passengers. Factors like excessive daytime napping, regular exercise, and healthy eating habits, while important for overall health and well-being, do not inherently contribute to fatigue in the same way that lack of rest does. In fact, proper sleep hygiene is often cited as the most effective means to combat fatigue in aviation environments.
