TAS SYMBOLOGY
The optional Traffic Advisory System (TAS) is designed to help in detection and avoidance of other aircraft. TAS
uses an on-board interrogator-processor and the Mode S transponder for the air-to-air traffic data link. Traffic is
displayed using the symbols shown in Table 6-21.

Table 6-21 TAS Symbol Description
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 5 nm.
A Proximity Advisory indicates that the intruding aircraft is within ±1200 feet and is within 5 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,
an4450cnd 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.
