In early 1997, the US Federal Aviation Administration (FAA) began developing a proposal entitled "Flight 2000". This proposal envisioned rapid deployment and field demonstration of advanced avionics capabilities leading toward implementation of free flight. The proposal was not well received by all segments of the aviation industry, and the industry's RTCA (Radio Technical Commission for Aeronautics) Select Committee on Free Flight endorsed a revised approach that included most Flight 2000 program activities. The revised approach was documented in the "Joint Government/Industry Roadmap for Free Flight Operational Enhancements".
