TRAFFIC ADVISORY (TA)
A symbol change to a filled yellow circle indicates that the Intruding air-
craft is considered to be potentially hazardous. Depending upon TAS
sensitivity level, TAS will display a TA when time to CPA (Closest Point
of Approach) is 15 to 30 seconds.
Here the Intruder is 500 feet above your aircraft. A
voice is heard in the cockpit, advising:
“Traffic, Traffic”
The crew should attempt to gain visual contact with the
Intruder and be prepared to maneuver upon visual
acquisition.
The crew should take no evasive action
based solely on the TAS display.
NO BEARING TRAFFIC
In installations with dual directional antennas with landing gear down,
when omnidirectional antenna is installed on the bottom of the aircraft, or
the intruder is located where the TAS cannot determine the azimuth of
the intruder, a “No Bearing” TA will be annunciated. If traffic can only be
seen by the bottom antenna as described above, a “No bearing” TA
would be annunciated as shown. Here the intruder is two nautical miles
away and co-altitude.
