Traffic (Tfc); Traffic Display Range Ring; Traffic Symbols - Garmin CNX 80 Pilot's Manual

The GNS 480 displays traffic when the GTX 33/330 Transponder or Skywatch system are configured with the
GNS 480. When available, the Traffic function is reached by pressing the FN key and then the TFC function
smart key. Traffic is displayed relative to the latest reported position. The relative altitude of the traffic from
your aircraft is shown as above (+) or below (-) in hundreds of feet. An altitude that is invalid is shown by
three dashes below the symbol. An arrow next to the altitude value shows the direction of traffic that is climb-
ing or descending at a rate greater than 500 fpm. See your traffic sensor documentation for more details on
symbols and other attributes of your particular system.
A Traffic pop-up screen will appear on any other page when a traffic advisory condition occurs.
The Map display can also be configured to add traffic as an overlay with the other map selections.

Traffic Display Range Ring

Range rings are used to display relative distances on the display. The current range values are shown on the
lower left edge the rings. The range is changed by turning the Small knob. At the 2 nm level only one ring is
displayed.
