4.3.4 TIS Alerts
When the number of Traffic Advisories (TAs) on the Traffic Map Page increases
from one scan to the next, the following occur:
•Asingle“Traffic” voice alert is generated.
•ATRAFFICAnnunciationappearstothetopleftoftheAttitudeIndicator
on the PFD, flashing for 5 seconds and remaining displayed until no TAs are
detected in the area.
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.
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:

obstacles around the radar site can further decrease radar coverage in all
directions.
