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 flashing black-on-yellow ‘TRAFFIC’ Annunciation (Figure 6-68) appears to the top left of the Attitude
Indicator on the PFD for five seconds and remains displayed until no TAs are detected in the area.
• The PFD Inset Map is automatically displayed with traffic.
This reduces the amount of nuisance alerts due to proximate aircraft. 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.

A voice alert is also generated when the TIS service becomes unavailable or is out of range: “Traffic Not Available”.
The volume of the voice alert is configured during installation. While the G1000 does not display indications
for TIS availability, the service may be unavailable in the radar coverage areas for any of the following reasons:
• Radar Out – The radar site may be out of service. If the TIS Mode S sensor is not operational, TIS is not
available.
• Out of Radar Range – Traffic beyond the maximum Mode S site range is not shown. If the client aircraft or
any other intruder traffic is beyond the range of the TIS capable Mode S site, TIS is not available.
• Radar Cone of Silence – Whether the client aircraft or the other traffic is above the radar site in the cone of
silence and out of range of an adjacent site, TIS data is not received.
• Below Radar Coverage – If the client aircraft or the other intruder traffic is below radar coverage, it is not seen.
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.
• No Transponder – Aircraft without an operating transponder are invisible to TIS. Aircraft without altitude
reporting capability are shown without altitude separation data or climb descent indication.
