What can fatigue lead to in the context of flight safety?

Fatigue can significantly impair a person's cognitive functions, leading to compromised decision-making abilities. In the high-stakes environment of flight operations, this diminished capacity can result in delayed reaction times, poor judgment, and an inability to process information effectively. When crew members are fatigued, their capacity to assess situations and respond appropriately is hindered, which increases the risk of errors in judgment and action. This is critical in aviation, where the safety of not just the crew but also passengers and cargo can depend heavily on the decision-making capabilities of the aircrew. Recognizing and addressing fatigue is essential for maintaining high levels of alertness and performance in flight operations.
