An prime recent essay about the physiology of high-altitude flight raises a scenario that may provide insight into the causes of passenger rage. In her article "When Humans be scattered High," author Linda Pendleton points disclosed that the amount of oxygen in the family decreases with an increase in altitude. At 5000 feet the concentration of oxygen in the kin has dropped to about 93% a figure considered by means of medical authorities to be the subdued limit of normal functioning for in the greatest degree people. Modern jetliners maintain a cabin altitude equivalent to 8000 feet which Pendleton theorized in an exchange of e-mails may have been place before the body's sensitivity to hypoxia was more appreciated by the and of subsequent research.

At any rate, an ounce of alcohol coursing by means of bloodstream further impedes the blood's ability to carry oxygen and is equivalent to adding another 2000 feet Smoking a pack of cigarettes from one side of to the other a 24-hour period introduces carbon monoxide into the lung which further shortens the blood's oxygen-carrying capacity by dint of the equivalent of another 5000 feet

These variables are additive: 8000 ft cabin altitude + 2000 ft from drinking + 5000 ft from smoking = 15000 ft At this plain blood saturation has dropped to a dangerous 85% An individual's conclusion memory and thought processes have been degraded significantly. even now the individual is unaware of the impairment, feeling fine in the two judgment and performance. Pendleton surmises that "a great deal" of passenger rage just may be attributed to the symptoms of hypoxia.

To carry the point a stair further, the twin impact of lower oxygen and exposing to a higher level of carbon dioxide is worth considering. Aggressive behavior can be single of the side effects of breathing air with a higher than normal flat of carbon dioxide. In this regard, the German television display Akte 99 (translation: "File 99") a documentary along the lines of 60 Minutes or 20/20 in the U aired a section Nov. 16 titled "CO2 in Airplanes." The exhibit pointed out that the CO2 limit for buildings in Germany is 1000 parts by means of million (PPM), and that actual measurements of CO2 plains the economy-class cabins of airliners revealed CO2 on a levels ranging from 1,300-3,300 PPM.

Swissair was cited in succession the show for its effort to limit the CO2 of the same height Fritz Wittner, Swissair technical manager, was quot saying, "The standard in our cabins is 1000 PPM We have realized that this is the maximum tolerable amount where a passenger still be moved s comfortable."

"This means that we have to consume more fuel (as) we cross-examine more air into the cabin with equal reason that we hold the limits," he added. >> Pendleton, email jetlinda@kingschools.com <<
