The Federal Aviation Administration has finally revised its 66-year-old assumptions about U.S. passenger weight. Here are a few reasons why

8.5 Pounds the average U.S. adult male weight increased, 1991 to 2000


170 Pounds the FAA assumed an average male passenger weighed,
1938 to 2003


184 Pounds the FAA currently expects an average male passenger to weigh, according to an August 2004 revision of weight assumptions


14.8 billion Gallons of jet fuel consumed by domestic air travel in 2000


350 million Gallons that could have been spared in 2000 if the average
U.S. adult weight remained at 1991 average


3.8 million Tons of carbon dioxide emissions generated by burning
350 million gallons of jet fuel


$275 million Cost of 350 million gallons of jet fuel in 2000


23.5 million Additional gallons of fuel required if every domestic-flight passenger in 2000 was served the Hardee´s 2/3-pound Monster Thickburger en route
