Surface Targets
Surface targets, in addition to ADS-B targets, are
supported and are shown as tan, rectangular ICONs.
They are displayed both on the Traffic Function page,
and on the Custom Map when traffic is turned on.
Traffic Altitude Values
Altitudes shown next to the traffic icon are in hundreds of
feet (09 = 900 feet). Altitude values shown in all other
locations and displays are the actual values in feet
(+100 = 100 feet).
