Traffic Information Service (Tis) - Garmin G900X Pilot's Manual

6.9 TRAFFIC INFORMATION SERVICE (TIS)

The Traffic Information Service (TIS) is intended for advisory use only. TIS is intended to help the
WARNING:
pilot locate traffic visually. It is the responsibility of the pilot to see and maneuver to avoid traffic.
TIS is available only when the aircraft is within the service volume of a TIS-capable terminal radar
NOTE:
site. Aircraft without an operating transponder are invisible to both Traffic Advisory Systems (TAS) and TIS.
Aircraft without altitude reporting capability are shown without altitude separation data or climb descent
indication.
TIS is disabled if a Traffic Advisory System (TAS) is installed.
NOTE:
Traffic Information Service (TIS) is designed to help in detection and avoidance of other aircraft. TIS uses the
Mode S transponder for the traffic data link. TIS receives traffic information from ground stations, and is updated
every 5 seconds. The G900X displays up to eight traffic targets within a 7.5-nm radius, from 3000 feet below to
3500 feet above the requesting aircraft. The system displays TIS traffic with the symbology shown in Table 6-27.
Traffic Advisories (TA) alert the crew to intruding aircraft. When traffic meets the advisory criteria for the TA,
a solid yellow circle symbol appears. A TA which is detected but is outside the range of the map on which traffic
is displayed are indicated with a message in the lower left corner of the map.
TIS also provides a vector line showing the direction in which the traffic is moving, to the nearest 45°. Traffic
information for which TIS is unable to determine the bearing (non-bearing traffic) is displayed in the center of the
Traffic Map Page (Figure 6-161) or in a banner at the lower left corner of maps other than the Traffic Map Page on
which traffic can be displayed (Figure 6-157).
The altitude difference between the requesting aircraft and other intruder aircraft is displayed above/below the
traffic symbol in hundreds of feet. If the other aircraft is above the requesting aircraft, the altitude separation
appears above the traffic symbol; if below, the altitude separation appears below. Altitude trend is displayed as
an up/down arrow (for speeds greater than 500 fpm in either direction) to the right of the target symbol. Traffic
symbols for aircraft without altitude reporting capability appear without altitude separation or climb/descent
information.
