UNCONTROLLED COPY WHEN DOWNLOADED OR PRINTED
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 traffic beyond 6
nm that is neither a TA nor PA.
A solid white rounded arrow indicates either a PA or
Non-Threat traffic with ADS-B directional information,
but the position of the traffic is shown with degraded
accuracy.
Relative altitude, when available, is displayed above or
below the corresponding intruder symbol in hundreds
of feet. When this altitude is above own aircraft, it is
preceded by a '+' symbol; a minus sign '-' indicates
traffic is below own aircraft.
A vertical trend arrow to the right of the intruder
symbol (Figure 7-2) indicates traffic is climbing or
descending at least 500 fpm with an upward or
downward-pointing arrow respectively.
If the intruding aircraft is providing ADS-B track
information, this is displayed as a vector line
extending beyond the traffic symbol in the direction of
the track (Figure 7-3).
