摘要：	Several research and development efforts to date have been aimed at demonstrating that Continuous Descent Arrival (CDA) procedures have the potential for significant environmental benefits including reductions in noise, emissions, and fuel burn. The benefits evaluation portion of these efforts typically involves evaluating small numbers of CDA flights under idealized flight test conditions. This paper focuses on the development and application of analyticalmethods for quantifying potential airport-wide environmental benefits of implementing CDAs. These efforts are being performed as part of the development of a CDA modeling capability within the U.S. Federal Aviation Administrations Aviation Environmental Design Tool (AEDT). Existing internationally accepted modeling methods and data are used, where appropriate, including methods described in the Society of Automotive Engineers (SAE) Aerospace Information Report (AIR) 1845, the Third Edition of European Civil Aviation Conference (ECAC) Doc 29,and data from EUROCONTROLs Aircraft Noise and Performance (ANP) database. These are used in conjunction with real-world operational and flight procedure data to look at the noise, emissions and fuel burn benefits of CDAs. The noise benefits are quantified in terms of changes in Day Night Average Sound Level (DNL) contours, the emissions benefits are quantified in terms of change in total mass of eight different pollutants, and the fuel burn benefits are quantified in terms of the change in total mass of the fuel burned. The benefits are evaluated based on both actual implementation levels and potential future levels of CDA implementation as a function of traffic flow density. This type of analysis may help support Air Traffic Management (ATM) decisions on CDA implementation based on tradeoffs between the efforts required to implement CDAs versus the predicted environmental benefits. / Supplementary Notes: Sponsored by Federal Aviation Administration, Washington, DC. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
