What does "CDO" stand for in air travel?

The term "CDO" stands for Continuous Duty Overnight in the context of air travel. This concept is significant in flight operation planning, particularly concerning crew scheduling and management of fatigue.

Continuous Duty Overnight refers to a schedule where flight crews are assigned to work through the night and usually require specific considerations for rest and duty times to ensure their alertness and safety during operations. This type of duty pattern can lead to various challenges, including the need for adequate rest periods and recovery time for crew members before the next duty period begins.

Understanding CDO is crucial for flight attendants and pilots as it impacts not only their own schedules but also overall flight safety and operational efficiency. The other options presented may contain varying terminology relevant to aviation, but they do not accurately represent the meaning of "CDO."
