Table 6-17 GTS 850 Traffic Symbols
A Traffic Advisory (TA), displayed as a yellow circle, 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.
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, 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, is displayed for traffic beyond 6 nm that is
neither a TA or PA.
Relative altitude, when available, is displayed above or below the corresponding intruder symbol in
hundreds of feet (Figure 6-114). When this altitude is above own aircraft, it is preceded by a ‘+’ symbol; a
minus sign ‘-’ indicates traffic is below own aircraft.
minus sign ‘-’ indicates traffic is below own aircraft.
A vertical trend arrow to the right of the intruder symbol (Figure 6-114) indicates traffic climbing or
descending at least five hundred feet per minute with an upward or downward-pointing arrow respectively.
