Traffic Information Service (TIS) (continued)
TIS Alerts (continued)
TIS customization options are available to the pilot by depressing the MENU
key while on the Navigation Map Page, and then selecting "Map Setup" then

Traffic Advisory System (TAS) - Optional
The optional Garmin GTS 800 is a Traffic Advisory System (TAS). It
enhances flight crew situational awareness by displaying traffic information
from transponder-equipped aircraft. The system also provides visual and
aural traffic alerts including voice announcements to assist in visually •
acquiring traffic.
The GTS 800 provides a system test mode to verify the TAS system is
operating normally. The test takes len seconds to complete. When the
system test is initiated, a test pattern of traffic symbols appears on the Traffic
Map Page. If the system test passes, the system announces, "T AS System
Test Passed" otherwise the system announces, "TAS System Test Failed."
When tbe system test is complete, the traffic system enters Standby Mode.
After power-up, the GTS 800 automatically enters STANDBY Mode
and no traffic depictions or alerts will be given. The GTS 800 must be in
OPERATE Mode for traffic to be displayed and for traffic advisories (TA)
to be issued. The pilot can manually change the system between STA.'IDBY
mode and OPERATE mode at any time via softkeys on the Traffic Map
page. If the pilot does not manually select a mode of operation, the system
will automatically transition from ST AND BY to OPERA TE 8-seconds
after becoming airborne and transition from OPERA TE Lo ST AND BY
24-seconds after landing. TAS aural alerts will be muted when GPS altitude
is less than 400 Ft above ground level (AGL).
