Do not confuse this functionality with full ADS-B capability, which can provide traffic information
NOTE:
from ADS-B Ground-Based Transceivers (GBTs) and ADS-B traffic outside of the TAS surveillance volume.
This system is limited to displaying ADS-B information from suitably equipped airborne aircraft within the
TAS surveillance volume.
A 1090 MHz extended squitter transponder is required to display ADS-B symbology for aircraft
NOTE:
providing ADS-B data.
A Traffic Advisory (TA), displayed as a yellow circle or triangle, alerts the crew to a potentially hazardous
intruding aircraft, if the closing rate, distance, and vertical separation meet TA criteria. A Traffic Advisory
that is beyond the selected display range (off scale) is indicated by a half TA symbol at the edge of the screen
at the relative bearing of the intruder.
A Proximity Advisory (PA), displayed as a solid white diamond or triangle, indicates the intruding aircraft
is within ±1200 feet and is within a 6 nm range, but is still not considered a TA threat.
A Non-threat Advisory, shown as an open white diamond or triangle, is displayed for all other traffic
beyond 6 nm that is neither a TA or PA.
