GMU Center for Air Transportation Systems Research, Volgenau School, with support from


FAA National Center of Excellence for Aviation Operations Research (NEXTOR)




This two-day symposium (non-credit short course) for students (graduate and undergraduate), scientists, and engineers explores the principal issues and techniques associated with air transport and its impacts on the environment.  This provides a basis (or an update) for continued work in this increasingly important and dynamic field.


Speakers include representatives of government, industry, and academia, and course materials will be distributed to registered participants.  There are no fees involved.


27 September (10am-4pm):          Noise, emissions, and climate effects

Physics and chemistry of these effects

28 September (10am-3pm):          Modeling techniques (hands-on)

                                                Policy and research issues


September 27-28, 2007

GMU Fairfax Campus, Research I

Pre-register (required) via email to with “AvEnv” in the subject.  Visit for additional information.




The objective of this symposium/shortcourse is to train aviation engineers and researchers on the most recent advances in science and engineering related to aviation and the environment.  The course will cover an overview of the environmental issues in aviation, and discuss quantitative methods for analysis of aviation environmental impacts in the areas of emissions, noise, and fuel efficiency.  The course will also cover new tools and technologies that will influence this field in the coming years.


The target audience for the course includes:


  • Government engineers and managers working in areas related to aviation and the environment.


  • Industry researchers, analysts,  and engineers working on projects impacted by environmental issues.


  • Academics, graduate students, and undergraduates doing (or considering) research in this area.


At the end of the short course, students will be able to:


  • Explain the issues facing air transportation related to the environment
  • Have a basic understanding of the science and engineering principles most relevant to aviation and the environment (and know where to find more information)
  • Know how to perform an analysis using NIRS/NST (Noise Integrated Routing System)
  • Know how to perform an analysis using AOS/GreenSim





The short course will include a mixture of presentations for academicians as well as practitioners. Emphasis will be on the running case studies using available tools, as well as a broad perspective on underlying science and policy issues.
