Your flight is scheduled to depart at 1300Z and the release was generated at 1200Z. What is the latest time that you can depart without getting an amended or new release?

• A. 1600Z
• B. 1400Z
• C. 1700Z
• D. 1500Z

Answer: (A)

A release has a defined validity window after it’s issued, and operations rely on that window staying current. Here, the release was created at 1200Z and is considered valid for four hours. That means you can depart any time up to 1600Z without needing an amended or new release. Departing at 1600Z is the latest moment still covered by the original release; any departure after that would require an amendment or a new release because the plan would be considered updated or changed. Your scheduled departure at 1300Z is well within the window.
