TIS Audio Alert
A TIS audio alert is generated whenever the number of
TAs on the Traffic Map Page display increases. Limiting
audio to TAs only reduces the amount of nuisance alert-
ing due to proximate aircraft. For example, when the first
TA is displayed, the crew is alerted audibly. As long as a
single TA aircraft remains on the TIS display, no further
audio alert is generated. If a second TA aircraft appears on
the display, a new audio alert is sounded. If the number
of TAs on the TIS display decreases and then increases, a
new audio alert is sounded. The TIS audio alert is also
generated whenever TIS service becomes unavailable.
The volume of the audio alerts and the choice between
a male or female voice is configured during installation.
The following TIS audio alerts are available:
• "Traffic" - TIS traffic alert is received.
• "Traffic Not Available" - TIS service is not available
or out of range.
TIS Traffic Status
The MFD indicates the following TIS traffic status to
the flight crew.
Traffic Banner
• AGE - if traffic data is not refreshed within 6
seconds, an age indicator (i.e., 'AGE 00:06') is
displayed in the lower left corner of the display,
when displaying traffic. After another 6 seconds,
if data is still not received, the traffic is removed
from the display. The quality of displayed traffic
is reduced as the traffic data becomes stale.
• TRFC COAST - the 'TRFC COAST' (traffic coast-
ing) banner located above the AGE timer indicates
that displayed traffic is held even though the
data is stale. The quality of displayed traffic is
reduced.

• TRFC RMVD - the 'TRFC RMVD' banner indicates
that traffic has been removed from the display due
to the age of the data. Data is too old to "coast"
when the time period is 12-60 seconds from the
last receipt of a TIS message. The crew should be
aware that traffic may be present but not shown.
• TA OFF - the 'TA OFF' scale banner displayed in
the lower left corner of the display indicates that
a traffic advisory is outside the selected display
range. The traffic advisory off-range banner is
removed when the traffic advisory is within the
selected display range.
• TRAFFIC - on the PFD, when the system receives
a traffic advisory a flashing 'TRAFFIC' alert is
displayed in the upper left hand portion of the
display. The PFD inset map also automatically
displays traffic data.
CAUTION: TIS warns the crew with voice and
visual traffic advisories whenever it predicts an
intruder to be a threat. The display and advi-
sories are intended only for assistance in visu-
ally locating the traffic and lack the resolution
and coordination ability necessary for evasive
maneuvering. Always attempt to visually clear
the airspace before maneuvering your aircraft in
response to a TA. See Appendix E for detailed
TIS information.
