AFMS, Garmin GTN GPS/SBAS System 190-01007-A2 Rev. 6Page 357.13 Garmin ADS-B Traffic System Interface (Optional)A Garmin ADS-B traffic system may be interfaced to the GTN. The nose of theownship symbol on both the GTN main map page and dedicated traffic pageserves as the actual location of your aircraft. The center of the traffic target iconserves as the reported location for the target aircraft. Motion vectors for trafficmay be displayed in either absolute or relative motion. The location of the traffictargets relative to the ownship are the same, regardless of the selected motionvector.Absolute motion vectors are colored either cyan or white, depending on unitconfiguration. Absolute motion vectors depict the reported track of the traffictarget referenced to the ground. An absolute motion vector pointed towards yourownship symbol does not necessarily mean the traffic target is getting closer toyour aircraft.Relative motion vectors are always colored green and depict the motion of thetraffic target relative to your ownship symbol. The direction the traffic target ispointed may vary greatly from the motion vector and a target may be gettingcloser to your aircraft independent of the direction the target is pointed. A greenrelative motion vector pointed towards your ownship indicates that the traffictarget is converging on your aircraft.If more than one target is occupying the same area of the screen, the GTN willcombine the two or more traffic targets into one traffic group. The presence ofan asterisk to the left of a target indicates that traffic has been grouped. Thehighest priority traffic target in the group is displayed to the pilot. When appliedto airborne targets the asterisk will be displayed in white or cyan depending onthe traffic depiction color used in the installation. The asterisk will be brown forgrouped ground targets. The asterisk will not turn amber, even if an alertedtarget is included in the group.An alerted target may be placed in the same group as non-alerted targets. In thiscase, the alerted target will be displayed. Two alerted targets will not be placedin the same group. All alerted targets will be displayed on the screen.Traffic targets displayed on the dedicated traffic page may be selected in orderto obtain additional information about a traffic target or to view all targets in agrouped target. When a grouped target is selected, the “Next” button on thededicated traffic page will cycle through all targets located in close proximity towhere the screen has been touched.
