How many consecutive hours are permitted to work at one time?

• A. 12 hours
• B. 14 hours
• C. 16 hours
• D. 18 hours

Answer: (B)

Fatigue management governs how long someone can work in one stretch. For a single duty period, the maximum consecutive hours is fourteen. This limit helps keep alertness and performance up, reducing the chance of mistakes as fatigue sets in. Shorter runtimes, like twelve hours, are more conservative but not the standard limit, while longer runtimes such as sixteen or eighteen hours would require relief, augmentation, or rest breaks to stay within safe boundaries.
