This paper discusses the requirements for surveillance and collision avoidance equipment in the National Airspace System (NAS), the current avionics equipage by the U.S. aircraft fleet, and the GA avionics market in general. The operational and functional requirements for a general aviation traffic alert system are presented accompanied by concept design, development and schedule information. The paper also discusses the issue of achieving compatibility with the existing Traffic Alert and Collision Avoidance System (TCAS) community.
