is being received from GTX 330 (Figure 10-7),
but there was a failure detected in the data stream.
The pilot should see the installer for corrective
action.
Figure 10-7 ‘Data Fail’ Message
• FAILED - ‘FAILED’ is displayed when the GTX
330 has indicated it has failed (Figure 10-8). The
pilot should see the installer for corrective action.
Figure 10-8 ‘Failed’ Message
• NO DATA - ‘NO DATA’ is displayed when no data
is being received from the GTX 330 (Figure 10-9).
The pilot should be aware that this status may be
a normal mode of operation in a dual transponder
installation where the GTX 330 with TIS is not the
selected transponder.
Figure 10-9 ‘No Data’ Message
• OPER - When the Traffic Page displays OPER in
the upper right hand corner of the display (Figure
10-11), the TIS system is in operational mode and
available to display traffic on the Traffic or Map
Page.
• STANDBY - When the Traffic Page displays
STANDBY (Figure 10-10), the TIS system is in
standby mode and cannot display traffic data.
Figure 10-10 ‘Standby’ Message
• TRFC CST - The ‘TRFC CST’ (traffic coasting)
banner (located above the ‘AGE’ indicator in
Figure 10-6) indicates that displayed traffic is held
even though the data is stale. The pilot should
be aware that the quality of displayed traffic is
reduced in this condition.
• TRFC RMVD - The ‘TRFC RMVD’ banner (Figure
10-11) indicates that traffic has been removed
from the display due to the age of the data being
too old to ‘coast’ (for the time period of 12-60
seconds from the last receipt of a TIS message).
The pilot should be aware that traffic may be
present but not shown.
