What does vibration contribute to that affects crew member performance?

Vibration significantly contributes to fatigue among crew members during flight operations. When an aircraft experiences vibration, it can lead to muscle fatigue as the body continuously works to stabilize itself and maintain posture despite the oscillations. This ongoing strain on muscles can result in decreased performance over time, affecting the crew's ability to concentrate and make sound decisions.

Moreover, prolonged exposure to vibration can cause discomfort and even pain, which can exacerbate overall fatigue levels. This cumulative effect can impair cognitive function, motor skills, and reaction times, ultimately impacting the efficiency of crew members in their operational duties. Recognizing vibration as a factor that induces fatigue allows for better management strategies to enhance crew performance and safety during flights.
