TAS Symbology

Traffic Advisory System (TAS) is designed to help in detection and avoidance
of other aircraft. TAS uses an on-board interrogator-processor to detect traffic.
Only aircraft with operating transponders will be detected. Traffic is displayed
according to TCAS symbology using four different symbols.
TAS Symbol
Non-Threat Traffic
(intruder is beyond 5 NM and greater than 1200 ft vertical
separation)
Proximity Advisory (PA)
(intruder is within 5 NM and less than 1200 ft vertical separation)
Traffic Advisory (TA)
(closing rate, distance, and vertical separation meet TA criteria)
Traffic Advisory Off Scale
A Non-Threat Advisory, shown as an open white diamond, indicates that an
intruding aircraft is at greater than ±1200 feet relative altitude or the distance is
beyond five NM.
A Proximity Advisory indicates that the intruding aircraft is within ±1200 feet
and is within five NM range, but is still not considered a threat.
A Traffic Advisory (TA) alerts the crew to a potentially hazardous intruding
aircraft. Closing rate, distance, and vertical separation meet TA criteria. A Traffic
Advisory that is beyond the selected display range is indicated by a half TA
symbol at the edge of the screen at the relative bearing of the intruder.
