If TCAS identifies a potential collision hazard, what type of advisory might it issue?

When TCAS, or the Traffic Collision Avoidance System, detects a potential collision hazard, it issues a Traffic Advisory (TA). This advisory alerts pilots to the presence of nearby aircraft that may pose a threat to safety, allowing them to take necessary precautions.

The purpose of a TA is to alert the pilots to the situation so they can visually acquire the intruder and prepare for possible maneuvers to maintain safe separation. This is part of the broader function of TCAS which aims to prevent mid-air collisions through timely information dissemination.

While other types of advisories may exist in various safety systems, they do not specifically relate to the immediate threats posed by nearby aircraft in the way that a Traffic Advisory does. Emergency advisories, weather advisories, and flight safety advisories serve other purposes and contexts that are not directly linked to collision avoidance with other aircraft.
