After simulator sickness, how long must personnel wait before flying?

• A. 24 hours
• B. 12 hours
• C. 48 hours
• D. 72 hours

Answer: (B)

After simulator sickness, the important point is to ensure the vestibular and central nervous systems have recovered before flying again. The symptoms—nausea, dizziness, headache, and imbalance—can temporarily impair reaction time, coordination, and judgment. Waiting about twelve hours gives most people time for these effects to subside, reducing the risk of in-flight impairment. If symptoms linger beyond that window or are still present, flying should be deferred and medical evaluation considered. Longer intervals like twenty-four, forty-eight, or seventy-two hours aren’t typically required unless a clinician determines otherwise.
