The FAA is superseding an existing airworthiness directive (AD) for the Eclipse EA-500 with Pratt & Whitney Canada PW610F-A engines. The existing AD requires operators to limit their maximum operating altitude to 37,000 feet. The new AD would restrict maximum operating altitude to 30,000 feet.

Eurocopter might exhibit a hybrid helicopter, using both piston engines and electric motors like a hybrid car, by Heli-Expo 2020. Parent company EADS last year unveiled a helicopter concept that could burn 50 percent less fuel than its traditional equivalent. EADS Innovation Works is devising a way to combine diesel engines, generators, batteries and electric motors.

Cessna's GreenTrak flight planning software will allow operators to use cost indexing to minimize trip costs and the cost of the European Emissions Trading Scheme or any likely U.S. "cap and trade" emissions charge by balancing DOCs, fuel burn and carbon emissions.

Turbofan manufacturers are developing cleaner, quieter and more environmentally friendly engines that will meet current and future regulatory requirements. That fact should come as no surprise, since they have been doing this all along as the natural byproduct of efforts to build more fuel-efficient and quieter turbofans for a market that demands nothing less.

The FAA awarded five contracts worth a total of $125 million over five years to engine manufacturers and Boeing to “develop and demonstrate technologies that will reduce commercial jet fuel consumption, emissions and noise.” The research is intended to accelerate introduction of green technology in the FAA’s Next Generation air traffic modernization program as part of the agency’s continuous lower energy, emissions and noise (Cleen) program.

Anthony Mosallam and Jonathon Deming, students at the Flabob Airport Preparatory Academy in Riverside, Calif., designed and built a turbine engine for their high school’s annual science fair. The engine was made from auto parts and a leaf blower, which was used to provide air to start the engine. A Buick Regal turbocharger was used as the compressor, and propane powers the engine.

Jetaire Aerospace of Fayetteville, Ga., says it has exceeded the compliance requirements for the SFAR (special FAR) 88 FAA Airworthiness Directive for explosion-suppressant systems for auxiliary fuel tanks. Its supplemental type certificate (STC) covers Phase I, Phase II and Phase III (as proposed) explosion-suppressant systems.

The recession’s lingering effects may prompt operators to consider storing their aircraft until conditions improve. That can make sense if the object is to slash costs and to avoid selling the airplane while prices are depressed. But there is a risk in storing aircraft for more than about 30 days that must be considered: an unused aircraft can deteriorate, which can have safety as well as financial implications.

Eurocopter’s new high-compression, diesel engine is expected to bring better environmental performance to turbine-powered helicopters as large as the EC 135.
The goal of the program is to reduce CO2 emissions by 40 percent and NOx emissions by 53 percent. The company announced the program, dubbed “Bluecopter,” at the Paris Air Show in June.
