What does CDO stand for in flight duty terms?

CDO stands for Continuous Duty Overnight in flight duty terms. This refers to a specific scheduling practice where flight crews are scheduled for a series of flights that involve overnight duties. It typically indicates that the crew will be working throughout the night with limited rest periods, which is crucial for ensuring compliance with regulations regarding crew rest and duty time.

Understanding CDO is important for flight crew members as it directly impacts their work-life balance, fatigue management, and overall safety in operations. The designation ensures that crew members are aware of their duty hours and can adequately prepare for their shifts, keeping in mind the potential challenges of overnight work. This knowledge helps in maintaining safety and efficiency standards in aviation operations.
