In a nod to increasing concerns about the environmental impact of aircraft, CFM International has successfully tested one of its engines fueled by a mix of biofuel and normal Jet-A1 kerosene.The company said the target is for a 20-percent reduction in carbon dioxide emissions.
As oil prices remain above the $60 per barrel mark, operators, oil companies and government regulators are showing ever more interest in alternative jet fuels. At a March 8 speech at the U.S.
As every pilot and mechanic knows, high temperatures are the bane of any engine. But as engineers strive to design smaller, more powerful turbine engines by adding compressor stages, the compression ratio goes up and so does the temperature of the ram air. At a compression ratio of about 20 to 25, ram-air cooling becomes inefficient. The solution, researchers believe, lies with cooling the air before it goes into the combustor.
Customers of Jeppesen World Fuel Services can now go online to view fuel prices and place orders at more than 1,500 locations worldwide. A new Web site provides price quotes, including taxes and fees, as well as pricing based on different uplift volumes. Users can store frequented destinations, search past fuel quotes and obtain the name of the into-plane provider.
In its bid to secure lower fuel prices for the aircraft operators it represents, AML Global is not trying to cut out the middleman. Instead, the company is trying to make the middleman bend a bit more to give the client a better deal.
Airliners now entering revenue service will be around for the next few decades, over which time forecasters expect the cost of kerosene to rise significantly. Higher oil extraction costs and likely carbon dioxide (CO2) emission limits will no doubt radically alter air transport economics. The industry will simultaneously have to drastically reduce CO2 emissions from aircraft engines and find alternative fuels for them.
AvFuel Corporation (Booth No. 1115) now offers its customers three convenient ways to purchase fuel at sales outlets: with a fuel card at the point of purchase, by arrangement over the phone before the flight or, as a new alternative, via the Internet at www.avfuel.com. The service is limited to North America for the time being.
European regional airlines don’t need to be told that fuel prices could stunt their growth. But one industry official believes that operators must start to view high fuel costs in the broader context of all expenses, and resist the temptation to blame them for all losses. Speaking at the ERA gathering, Professor Judith Patterson reminded operators of commercial aviation’s fundamental dependence on petroleum, “unlike other transport modes.”
Airport information provider AirNav is launching AirBoss, a new fuel card membership service that is open to pilots and FBOs. For pilots, annual membership costs $39 (100 octane) or $79 (100-octane and jet-A) and provides discounted fuel at AirBoss FBOs. FBOs don’t pay a fee to join AirBoss but must advertise on AirNav’s online airport database.
Fuel on Demand (www.fuelondemand. com), which debuted in November at the NBAA Convention, is a national program offering jet-A at “cost plus 25 cents per gallon” pricing, with no minimum or maximum purchase. The program is designed to provide participants lower and more predictable fuel prices compared with volume-based programs.
