TIS Traffic Display Status and Pilot Response
• AGE - If traffic data is not refreshed within 6
seconds, an age indicator (e.g., ‘AGE 00:12’) is
displayed in the lower right corner of the display
(when displaying traffic). See Figure 12-6. After
another 6 seconds, if data is still not received,
the traffic is removed from the display. The pilot
should be aware that the quality of displayed
traffic is reduced in this condition.

but there was a failure detected in the data stream.
The pilot should see the installer for corrective
action.

• FAILED - ‘FAILED’ is displayed when the GTX
330 has indicated it has failed (Figure 12-8). The
pilot should see the installer for corrective action.

• NO DATA - ‘NO DATA’ is displayed when no data
is being received from the GTX 330 (Figure 12-9).
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.

• OPER - When the Traffic Page displays OPER in
the upper right hand corner of the display (Figure

available to display traffic on the Traffic or Map
Page.
