A state of physical or mental exhaustion that degrades pilot performance. Fatigue reduces reaction time, decision-making ability, and situational awareness. It is a factor in many aviation accidents.

Why Fatigue Matters for Pilots

Understanding Fatigue is important for pilot certification exams and safe flight operations. This concept appears on FAA and EASA knowledge tests, and examiners may ask about it during oral checkrides. A thorough understanding of Fatigue helps you make better decisions in the cockpit.
