How many hours away from station is an aircraft considered deployed?

• A. 12 hours
• B. 11.9 hours
• C. 48 hours
• D. 24 hours

Answer: (B)

Deployment status is determined by how long the aircraft is away from its home station. The standard uses a precise boundary of 11.9 hours. In practice, a mission that keeps the aircraft away from its home base for about 11 hours 54 minutes or more is counted as deployed, which triggers deployment-related maintenance, logistics, and support actions. This exact figure avoids rounding issues across time zones and logs, giving a clear, consistent cutoff. The other options are simply rounded or longer timeframes that do not match this specific deployment cutoff.
