TRAFFIC DESCRIPTION

ADS-B traffic operation is similar to the TAS systems discussed previously, but ADS-B
adds additional symbology. The symbols used to display ADS-B traffic are shown in
the table below. The traffic identifier and altitude are displayed below the traffic symbol. A
small up or down arrow next to the traffic symbol indicates that 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.
