Traffic Advisory with directional information. Points in the
direction of the intruder aircraft track.
Traffic Advisory without directional information. Traffic
Advisory (TA) targets are typically displayed as a yellow circle
and are generated when the GTS predicts that a target may
pose a collision threat. Traffic Advisory sensitivity, criteria, and
types are described in the following sections.
Traffic Advisory out of the selected display range. Displayed
at outer range ring at proper bearing. If a TA is beyond the
currently-selected traffic display range, it is typically shown
with a half-circle icon at the edge of the display range. Refer
to the traffic display documentation for details regarding off-
scale TA depictions.
Proximity Advisory with directional information. Points in the
direction of the aircraft track.
Proximity Advisory (PA) without directional information. PA
targets are typically displayed as a solid diamond. PAs are
defined as traffic within 6 NM horizontally and 1200 feet
vertically that are not a Traffic Advisory.
Non-threat traffic with directional information. Points in the
direction of the intruder aircraft track.
Non-threat traffic without directional information. Other
Traffic (OT) targets are typically displayed as a hollow
diamond and do not meet the criteria for any other traffic
type.
Traffic located on the ground with directional information.
Points in the direction of the aircraft track. Ground traffic is
only displayed when ADS-B is in Surface (SURF) Mode or own
aircraft is on the ground.
