What verbal alert does TCAS issue during a traffic advisory?

During a traffic advisory, the Traffic Collision Avoidance System (TCAS) issues the verbal alert "TRAFFIC, TRAFFIC." This alert is designed to inform the flight crew that there is nearby air traffic that could pose a potential collision risk, allowing pilots to remain vigilant and assess the situation. It's an important safety feature in aircraft to enhance situational awareness and provide timely information about other aircraft in the vicinity.

The TCAS system provides this auditory warning to assist pilots in identifying and avoiding possible conflicts, though it does not issue guidance on immediate corrective actions, unlike in cases of a resolution advisory where commands such as "CLIMB" or "DESCEND" may be given. The "CLEAR OF CONFLICT" alert would indicate that there is no longer a threat, typically after a resolution advisory has led to a safe outcome. Each alert serves a distinct purpose within the TCAS framework, focusing on the pilot's situational awareness and decision-making.
