What is one common human factor that can impact flight safety?

Fatigue or stress is a significant human factor that can critically impact flight safety. When an individual experiences fatigue, their cognitive functions, including attention, memory, decision-making, and situational awareness, can be severely impaired. This reduction in mental acuity can lead to slower reaction times and a higher likelihood of errors in judgment. Similarly, stress can create distractions and adversely affect a person's ability to focus on vital tasks. In the high-stakes environment of aviation, where precision and timely responses are crucial, both fatigue and stress can compromise the safety of flight operations by leading to mistakes or oversights that could result in accidents. Understanding and mitigating these human factors through proper training and awareness can enhance safety and improve overall operational effectiveness in aviation.
