A blueprint for next-gen technology
Alaska Airlines is demonstrating the emissions-saving potential of next-generation flight procedures during a series of test flights. It is now seeking FAA approval for the Required Navigation Performance (RNP) procedures, which are based on satellite guidance technology. RNP could ultimately be used by all properly equipped carriers at Seattle-Tacoma International Airport (Sea-Tac), where the trials are taking place.
The most recent test flight over Puget Sound, using a 737-700, burned less fuel and reduced emissions by 35 per cent compared to a conventional landing. With a landing weight similar to a typical passenger flight, the shorter and more efficient approaches reduced carbon emissions and saved 400 pounds of fuel per approach.
Testing for the project began last summer, and Alaska Airlines has since flown two other demonstration flights and submitted more than half of the proposed procedures for FAA review. Alaska estimates the new procedures will cut fuel consumption by 2.1 million gallons annually and reduce carbon emissions by 22,000 metric tons at Sea-Tac. Overflight noise will be reduced for an estimated 750,000 people living below the affected flight corridor.
"Sea-Tac is the ideal location to pursue this cutting-edge project," said Ben Minicucci, Alaska's chief operating officer. "Seattle has the highest percentage of advanced RNP-equipped planes in the nation, and – working with the FAA – Alaska Airlines, Boeing and the Port of Seattle are committed to making 'Greener Skies' a reality as soon as possible. Ultimately this project could serve as a blueprint for next-generation aviation technology throughout the country."
Planning and testing of the procedures will continue throughout the remainder of 2010 and will be integrated into Alaska Airlines and sister carrier Horizon Air's commercial operations at Sea-Tac, pending FAA approval.
