The traffic alert and collision avoidance system (TCAS) is an airborne collision
avoidance system designed to reduce the incidence of mid-air collisions between
aircraft. Currently, TCAS II is dependent upon 1090 MHz replies that are elicited by
1030 MHz interrogations. These provide the pilot with information about the relative
distance, bearing and aircraft altitude and are used to build active tracks. However,
the process uses precious frequency bandwidth that is also needed for surveillance
purposes.
