12.44 TCAS

12.44.2 Briefly describe the basic function and operation of TCAS.

The Traffic Alert and Collision Avoidance System (TCAS) is an airborne system that provides pilots with traffic advisories and collision avoidance guidance. The system uses radio signals to communicate with other aircraft and determine their position and altitude. When the system detects a potential collision threat, it provides the pilot with visual and audible alerts, as well as guidance on how to avoid the threat. The TCAS system operates independently of ground-based air traffic control and is designed to provide an additional layer of safety in the event of a breakdown in communication or other failures.
