Motion Sickness Symptoms and Postural Changes Following Flights in Motion-Based Flight Trainers
R.S Kennedy, G.O. Allgood, B.W. Van Hoy, M.G. Lilienthal
Navy pilots flew over 193 standard training mission scenarios while acceleration recordings in three linear dimensions were made for two moving-base flight trainers. The pilots, who were of comparable age and experience in both groups, were interviewed for motion sickness symptomatology and were tested for ataxia after leaving the simulators.
The data are discussed from the standpoint that simulator sickness in moving-base simulation may be, at least in part, a function of exposure to frequencies that make people sick.
