Honeywell (Booth No. 2600) has completed initial testing of renewable jet fuel on its TPE331 and TFE731 engines and an auxiliary power unit. Performance and fuel economy were comparable to typical aviation fuels, but emissions were reduced by 15 to 50 percent depending on the engine and its power setting. The biofuel blend tested was developed by UOP, a Honeywell subsidiary based in Des Plaines, Ill.
How many coconuts does a Boeing 747 need to fly from London to Amsterdam?
Last year amid much fanfare, a Virgin Atlantic 747-400 with one of its four engines fueled by a mix of 80 percent jet-A and 20 percent coconut and babassu oils flew the route in 40 minutes. Had all four engines been flying on biofuels alone, it would have required the oil from several million coconuts.
The FAA’s recent special airworthiness information bulletin (SAIB: NE-09-25R1) regarding recommended safe-operating guidelines in the possible presence of the jet-fuel contaminant Fame (fatty acid methyl ester) has caused some confusion among operators. The agency is concerned that jet fuel could be exposed to Fame contamination through the use of multi-product fuel-transport systems and is taking steps to begin educating operators.
Government, industry look to curb CO2 emissions
Air Fuel Synthesis (AFS), a UK- based company founded by a small group of scientists and engineers, is reaching out to the aviation industry in the hopes of marketing a carbon-neutral jet fuel made from carbon dioxide and hydrogen.
The prospect of synthetic fuel qualification took an important step closer to reality last month when ASTM International’s aviation fuels subcommittee passed a new specification for alternative jet fuel. The new specification details the properties and criteria required to control the production and quality of synthetic fuels for aviation use.

Aviation will become greener in small steps rather than the giant leaps hoped
Costa Rican regional airline NatureAir has entered talks with the government of the Central American republic for permission to sell biodiesel fuel to other companies. Despite the fact that its fleet of six de Havilland Canada Twin Otter turboprops runs on jet-A, serving 17 destinations in Costa Rica and Panama, NatureAir calls itself the world’s first carbon-neutral airline.
As concern for the environment gathers urgency, a number of manufacturers are studying the use of biofuels, which they consider a low-CO2 alternative to petroleum-based fuels.
