What can contribute to increased pilot fatigue?

Multiple consecutive long flights without rest significantly contribute to increased pilot fatigue due to the cumulative effects of prolonged activity without adequate recovery time. When pilots engage in extended flying sessions, particularly without breaks, they may experience mental and physical exhaustion, which can impair their decision-making, situational awareness, and overall performance.

Fatigue can result from various factors, but the relentless demands of multiple long flights can lead to a depletion of energy reserves and an inability to maintain focus. Over time, this can not only affect a pilot's ability to perform but also heighten the risk of errors during critical phases of flight. This aspect emphasizes the importance of rest and recovery in maintaining optimal performance levels for pilots.
