The requirements for an airborne collision avoidance system (CAS) are discussed. They include accommodation for all types and large numbers of aircraft, compatibility with ground-based air traffic control, response time factor, and safe separation for aircraft. A system for meeting these requirements is proposed; it is a time-frequency system, using cooperative equipment in all participating aircraft. The mechanics of operation of the system are explained.
