Five aerospace companies have been chosen to "develop and demonstrate technologies that will reduce commercial jet fuel consumption, emissions and noise" with the aid of $125 million in FAA grants. Noting "phenomenal progress" over the past decade, FAA Administrator Randy Babbitt vowed his agency "is going to push as hard as humanly possible to improve aviation's environmental efficiency." The Continuous Lower Energy, Emissions and Noise program, or CLEEN, seeks to encourage more efficient technologies in engine and airframe design. Alaska Airlines, in partnership with three other aviation companies and the FAA, will perform test flights using flight management system technologies being studied under the five-year program.
