NASA and Centennial Challenge partner organization, the Comparative Aircraft Flight Efficiency, or CAFE, Foundation of Santa Rosa, Calif., are encouraging aerospace enthusiasts to attend the Green Flight Centennial Challenge, set to be held at the Sonoma County Airport in Santa Rosa from Sept. 25 to Oct. 1.
Teams from across the United States will test electric, biofueled and hybrid-powered aircraft, vying to be the most fuel-efficient small aircraft in the world. They're competing for a competition purse of $1.65 million -- the largest aviation prize ever offered.
Competitors will tackle a fuel efficiency competition Sept. 27 and a speed competition Sept. 29. To win the fuel competition, an aircraft must fly 200 miles in less than two hours, using less than one gallon of fuel per occupant, or an equivalent amount of electricity. If more than one aircraft meets that criteria, the competitor whose aircraft delivers the best combination of speed and efficiency will take home the prize, according to the competition guidelines.
