System (BCAS), a transponder-based. airborne system. In 1978, a second mid-air collision. occurred near San Diego between an air carrier and a. general-aviation aircraft, leading to the expansion of. the BCAS effort; in 1981, the name was changed to the. Traffic Alert and Collision Avoidance System (TCAS).
In the air, other systems have. been developed and are currently in use to prevent mid-. air collisions. This article focuses on the widely fielded, crucial technology called the Traffic Alert and Collision. Avoidance System (TCAS).
