NASA/CR—2011-217302 A Concept for Flexible Operations and Optimized Traffic into Metroplex Regions Daniel DeLaurentis, Steve Landry, and Dengfeng Sun Purdue University, West Lafayette, Indiana Fred Wieland and Ankit Tyagi Intelligent Automation, Inc., Rockville, Maryland National Aeronautics and Space Administration Langley Research Center Prepared for Langley Research Center Hampton, Virginia 23681-2199 under Contract NNL10AA15C 'HFember 2011 Acknowledgments The authors acknowledge, first and foremost, the sponsorship of this research by the National Aeronautics and Space Administration under contract NNL10AA15C. In particular, the input and coordination of project Technical Monitor, Michael Sorokach, and Metroplex Lead Scientist, Rosa Oseguera-Lohr (both from the NASA Langley Research Center) were of tremendous value to our research team. Finally, the authors acknowledge the significant efforts of the dedicated team of graduate students at Purdue University without whom much of the progress reported in this document would not have been possible: Seung Yeob (Simon) Han, Yiwu Jian, Taehoon Kim, Vishnu Vinay, and Peng Wei. We sincerely thank them all and hope their education was enhanced by this project experience.
