TRAFFIC DESCRIPTION
ADS-B traffic operation is similar to TIS-A discussed previously, but ADS-B adds
additional symbology and capabilities. The symbols used to display ADS-B traffic are
shown in the table below. The traffic label and altitude are displayed below the traffic
symbol. A small up or down arrow next to the traffic symbol indicates the traffic
is climbing or descending at a rate of at least 500 feet per minute. The vector line
that extends from the traffic symbol is just further indication of the intruder aircraft
track. For directional traffic symbols, the arrow head points in the direction of aircraft's
ground track.

(ta)
TAs are issued for traffic when they are predicted to be within a specified volume of
airspace around the aircraft in a specified amount of time. The protected volume and
time interval varies based on the current geodetic altitude and groundspeed. Thus, the
protected volume of airspace increases with altitude and ground speed. Refer to the
following table for details.
