Research on next-generation air traffic management systems is being conducted at several laboratories using custom software. In order to provide a more uniform research platform for en route air traffic management research, NASA has recently developed the FACET software package. While FACET incorporates most of the features required for conducting research, it is sometimes necessary to extend its capabilities. However, this can demand a significant programming investment. The Phase I SBIR project developed the prototype version of scriptable software that allows simpler access to FACET functionality. This software is termed CARAT# (Configurable Airspace Research and Analysis Tool ? Scriptable). The first version of CARAT# is built upon a commercial software platform, while a second version employs a freely available, scriptable environment as its foundation. The use of CARAT# was illustrated by formulating four research problems during the Phase I research. By making the capabilities of FACET accessible to a larger population of researchers, CARAT# can help accelerate the pace of air traffic management research. The complete version of the CARAT# software will be developed during the Phase II work. Additional research problems will also be formulated. The software will be commercialized to the ATM research community towards the end of Phase II research.
