To experience a redout, the pilot must be inverted while exposed to G-forces, which can also happen in any vehicular accident on land, at sea or in the air. In general, a whiteout is produced by the opposite effect that causes a greyout and a redout out is the inverse of a blackout. Fortunately, fighter pilots are trained to recognize the effects of G-force and use the changes in vision as an indicator that they are reaching maximum performance without losing consciousness. However, auto accidents, amusement park rides, strenuous activities, medical conditons, prescription or over-the-counter drugs and certain occupations, create exposures for sudden changes to your vision. Days that have a high "feels like" temperature are common culprits.įighter pilots experience more whiteout, blackout, greyout, and redout situations than the average person. Whiteouts due to physical exertion most often subside after a few minutes of rest and recovery. Whiteouts due to cardiovascular changes are more common in aging adults and can often be reversed by having them sit down for moment to regroup. It can be caused by heat exhaustion, dehydration, emotional distress, standing up quickly, taking certain medications, heart problems or a sudden drop in blood pressure. As a precursor to passing out, it is sometimes accompanied by a loss of peripheral vision and usually occurs much more slowly than a blackout.įainting or blackout usually happens when someone's blood pressure drops suddenly, which causes a decrease in blood flow to his or her brain. A whiteout or greyout is a transient loss of vision characterized by a perceived dimming of light and color. Syncope or fainting is a temporary loss of consciousness where your skin becomes cold and clammy, you feel lightheaded or nauseous, and changes begin to occur in your field of vision. It is common to a see an inexperienced passenger losing consciousness as a jet pilot takes him or her through a series of aerial maneuvers that pull both positive and negative G's. That's especially important if you're playing a sport or it's hot outside.What Is the Difference Between a Whiteout and a Blackout? Also avoid environments that are cramped, stuffy or overheated. This process will help improve blood flow to the heart and brain. If you have to stand or sit for a while, occasionally tense your leg muscles or cross your legs. Move from a sitting position to a standing one. Once you feel better, stand up again slowly. This will help blood circulate to the brain. Move slowly to an upright seated position. It will help blood circulate to the brain.
