To reduce
• Simulator flights should not be scheduled on the same day as aircraft flights.
• Arrive for simulator training in your usual state of health and fitness.
o Avoid fatigue or sleep loss, hangover, upset stomach, head colds, ear infections, ear blockages, upper respiratory illness, medications, and alcohol.
o If you have been sick recently and are not fully recovered, reschedule your simulator training.
• Persons who are new to the simulator, or who have not operated it in months, are at risk.
• Do not schedule simulator sessions for greater than two hours for any reason.
o Use breaks, time-outs extensively.
o The more nauseogenic the session, the shorter the session should be.

Aggressive, violent maneuvers, near ground level, are more nauseogenic than high, straight-and-level flight.
• Adaptation is one of the most potent fixes for SS.
o In order to optimize adaptation, there should be a minimum of one day between simulator sessions, and a maximum of seven days.
o Begin with short sessions, using non-nauseogenic maneuvers.
o Minimize rapid gain and loss in altitude; minimize abrupt or continued roll; minimize porpoising.
o Fly the most provocative tasks at the end of the session.
• Minimize head movement, particularly when new or dynamic maneuvers are being trained.
• Tell your instructor if you are experiencing discomfort.
• The instructor should avoid, or at least minimize, use of the freeze command.
o Have the pilot close his or her eyes before using the freeze command.
o Have the pilot close his or her eyes before resetting the simulator to another location. Or, turn off visual display before reset.
• The instructor should turn off visual display and turn on cabin lights before asking the pilot to exit the simulator.
• The instructor should decrease the field of view (turn off side displays) during early sessions, nauseogenic maneuvers, or if the pilot shows any symptoms of discomfort.
o Or, go on instruments at the first sign of discomfort.
• Avoid high-risk activities for at least 12 hours after simulator training.
o High-risk activities include flying, climbing, driving, riding motorcycles, riding bicycles, or diving.
o Use handrails to help maintain balance when going up or down stairs.
