As part of research activities under the NASA/FAA Joint Universities Program, the MIT International Center for Air Transportation is investigating factors that may act as barriers to the utility of general aviation (GA) transportation in North America. If you use the North American GA transportation system, then MIT would appreciate your feedback on what factors reduce GA utility and what can be done about it. The Web-based survey takes only a few minutes to complete. It is located at web.mit.edu/downen/ www/. “Your input is important,” said MIT’s Troy Downen. “This information will help engineers improve access to travel by general aviation aircraft.”
