What is the recommended maximum duration for simulator sessions to minimize simulator sickness?

• A. 2 hours
• B. 1 hour
• C. 3 hours
• D. 4 hours

Answer: (A)

Simulator sickness results from a mismatch between what your eyes see and what your vestibular system feels. When you’re in a high-immersion simulator, you may perceive motion that your body isn’t actually experiencing, and that sensory conflict tends to build with longer exposure. Limiting continuous time in the simulator helps keep symptoms like nausea, dizziness, and fatigue from outweighing the training benefit. The best-supported maximum for a single session is about two hours. This duration provides meaningful practice while keeping the risk of sickness and performance decline reasonably low. If you push beyond two hours, symptoms become more likely, and performance can deteriorate, which is why longer sessions (three or four hours) aren’t advised. Shorter sessions, such as around an hour, are even safer but aren’t the maximum limit.
