Window Of Circadian Low
Window of Circadian Low (WOCL) is a period of time during a 24-hour day when the human body experiences a decrease in alertness and cognitive performance due to the natural circadian rhythm. In aviation, WOCL is an important consideration for flight crew scheduling as it can affect their ability to perform critical tasks during flight. The WOCL typically occurs during the early morning hours, between 2:00 AM and 5:59 AM, and can vary depending on an individual's sleep patterns and time zone changes. Flight crew scheduling should take into account the WOCL to ensure that pilots and other crew members are not scheduled for critical tasks during this period, which could compromise flight safety.
