Download or read book Aviation and the Environment: NextGen and Research and Development are Keys to Reducing Emissions and Their Impact on Health and Climate written by Gerald L. Dillingham and published by DIANE Publishing. This book was released on 2008-10 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collaboration between the fed. gov¿t. and the aviation industry has led to reductions in aviation emissions (AE), but growing air traffic has partially offset these reductions. Various fed. agencies are working to increase the efficiency, safety, and capacity of the nat. airspace system and at the same time reduce AE, in part, by transforming the current air traffic control system to the Next Generation Air Transp. System (NextGen). This effort involves new technologies and air traffic procedures that can reduce AE and incorporates R&D on emissions-reduction technologies. This testimony addresses: (1) the scope and nature of AE; (2) the status of selected key fed. efforts to reduce AE; and (3) next steps and challenges in reducing AE. Illustrations.
