Honeywell made history in Paris on Saturday morning, landing its Gulfstream G450 jet at Le Bourget after the first transatlantic flight using biofuel, according to a press release. The trip’s green credentials can be measured in the 5.5 metric tons of carbon dioxide (CO2) saved in the course of the seven-hour flight from the New York-area Morristown Airport. The G450’s fuel system was set so that number-one (left) engine burned a 50/50 blend of “Honeywell Green Jet Fuel” and standard jet-A fuel, while the other engine consumed pure jet-A. According to James Rekoske, Vicepresident and General Manager of renewable energy and chemicals for Honeywell UOP, which has led the two-and-a-half-year biofuel development program, the flight accomplished two goals. First, it demonstrates the willingness of the aviation industry to participate in the search for more environmentally friendly fuel sources, and second, it advances approval by the U.S.
