Foreword System Sec 1 PFD Sec 2 MFD Sec 3 Features Avoidance 4.5.3 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 Description 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 Table 4-6 Traffic 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 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.
