Zoom Buttons
Zoom In (+) and Zoom Out (-) buttons are located on the bottom of
each trafc screens. The buttons are used to change the trafc display
range.
Range Rings
The range rings are oriented around the ownship. A range indicator is
located outside the upper left corner of the outer most ring. Bearing

controlled by the zoom buttons.
The Trafc screen has the following display range with additional inner

• Range 40 has 40 nm and 24 nm range rings.
• Range 24 has 24 nm and 12 nm range rings.
• Range 12 has 12 nm and 6 nm range rings.
• Range 6 has 6 nm and 2 nm range rings.
• Range 2 has only the 2 nm range ring.
• Range 1 has only the 1 nm range ring.
• Range 0.5 has only the 0.5 nm range ring.
TFC Button
The Trafc (TFC) button replaces the Trafc Altitude Mode button
when the status of the aircraft is On-Ground. The button also activates
TAS (optional) when the aircraft is On-Ground. A description of each
mode is detailed below:
• Ground (GND): The display shows ADS-B ground trafc only
and places TAS (if installed) in Standby. TAS Standby indication
is located on the Trafc Mode Indicator. This is the default mode
when the aircraft goes on ground.
• Air (AIR): The display shows air trafc only and activates TAS (if
installed).
• All (ALL): The display shows air and ground trafc and activates
TAS (if installed).
Note
When no heading source is available and when going
through low speed operations (< 7 knots), ADS-B tracks
are removed because ownship track can not be adequately
determined. If TAS is not active, a “Trafc Unavailable”
message is displayed.
