What is the impact of crew fatigue on flight safety?

Crew fatigue significantly impairs decision-making and reaction times, which are critical components of flight safety. When crew members are fatigued, their cognitive functions may diminish, leading to slower judgment and decreased situational awareness. This impairment can cause delays in responding to changing conditions, failure to notice critical cues, and poor communication among team members.

Fatigue also impacts physical performance, making it harder for crew members to execute tasks that require fine motor skills or quick reflexes. The cumulative effect of these impairments can increase the likelihood of errors, ultimately jeopardizing the safety of the flight. Addressing and mitigating crew fatigue is essential for maintaining high standards of safety and operational effectiveness in aviation.
