TRAFFIC DESCRIPTION
ADS-B traffic operation is similar other traffic systems, 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 an indication of the intruder aircraft track.
