TIS System Status

The GDU 620 performs an automatic test of TIS during power-up. If
TIS passes the test, TIS enters Standby Mode on the ground or Operating
Mode in the air. If TIS fails the power up test, an annunciation is shown
in the center of the Traffic Map Page.

The traffic mode is annunciated in the upper left corner of the Traffic Map Page.
When the aircraft is on the ground, TIS automatically enters Standby Mode. If
traffic is selected for display on another map while Standby Mode is selected,
the traffic display enabled icon is crossed out (also the case when TIS has
failed). Once the aircraft is airborne, TIS switches to Operating Mode and traffic
information is displayed. The mode can be changed manually using soft keys or
the page menu.
