What does a TCAS Traffic Advisory (TA) indicate?

A TCAS Traffic Advisory (TA) indicates an amber alert, signaling to the pilot that there is potential traffic in close proximity which may require increased situational awareness. This alert is not as urgent as a resolution advisory (RA) but still signifies the need to pay attention to air traffic around the aircraft.

When a TA is triggered, it informs the flight crew to be aware of conflicting traffic, and it typically involves visual and auditory cues. The goal of this alert is to ensure pilots are cognizant of their environment and potential hazards, allowing them to make informed decisions in a timely manner.

This amber alert status is an important aspect of the TCAS system, as it helps maintain awareness before a more critical situation arises that might result in a red alert or a resolution advisory, which would require immediate action.
