Tis Alerts - Garmin G1000:Beechcraft Baron 58/G58 User Manual

HAZARD AVOIDANCE

TIS ALERTS

When the number of TAs on the Traffic Map Page increases from one scan to the next, the following occur:
• A single "Traffic" voice alert is generated.
• A TRAFFIC Annunciation appears to the top left of the Attitude Indicator on the PFD, flashing for 5 seconds
and remaining displayed until no TAs are detected in the area.
• The PFD Inset Map is automatically displayed with traffic.
To reduce the number of nuisance alerts due to proximate aircraft, the "Traffic" voice alert is generated only
when the number of TAs increases. For example, when the first TA is displayed, a voice and visual annunciation
are generated. As long as a single TA remains on the display, no additional voice alerts are generated. If a second
TA appears on the display or if the number of TAs initially decreases and then subsequently increases, another
voice alert is generated.

TA is Detected
A "Traffic Not Available" (TNA) voice alert is generated when the TIS service becomes unavailable or is out of
range. TIS may be unavailable in the radar coverage area due to the following:
• Radar site TIS Mode S sensor is not operational or is out of service
• Traffic or requesting aircraft is beyond the maximum range of the TIS-capable Mode S radar site.
• Traffic or requesting aircraft is above the radar site in the cone of silence and out of range of an adjacent site.
• Traffic or requesting aircraft is below radar coverage. In flat terrain, the coverage extends from about 3000
feet upward at 55 miles. Terrain and obstacles around the radar site can further decrease radar coverage in all
directions.
• Traffic does not have an operating transponder.
The "Traffic Not Available" (TNA) voice alert can be manually muted to reduce nuisance alerting. TNA
muting status is shown in the upper left corner of the Traffic Map Page.
