How can fatigue affect pilot performance?

Fatigue significantly impairs attention and decision-making, which is critical for pilot performance. When a pilot is fatigued, cognitive functions such as memory, problem-solving, and situational awareness are adversely affected. This can lead to slower reaction times, difficulty concentrating on flight tasks, and an increased likelihood of making errors. Furthermore, fatigue can cause a decrease in overall vigilance, making it harder for pilots to monitor instruments and respond to changes in the operating environment. Understanding this impact is essential for maintaining flight safety, as fatigue management becomes a key element in ensuring that pilots operate at their highest level of competency and focus.
