Environmental Challenge: How to Close the Gap Between Policy and Technology?

and the technology portfolios currently under development in various research & development establishments. This paper demonstrates one such capability, developed for NASA’s Subsonic Fixed Wing Project, as a means of rapidly looking at what technology combinations might help close the gap between the current trends and dierent proposed policies. It makes use of a rapid technology modeling process and parts of the US FAA’s environmental analysis tool suite. The process is demonstrated using a set of dierent technology \futures" ranging from \frozen", to including a range of systems proposed by NASA and compares them to dierent policy goals.
