6.4 TRAFFIC INFORMATION SERVICE (TIS) HAZARD AVOIDANCE WARNING: The Traffic Information Service (TIS) is intended for advisory use only. TIS is intended to help the pilot locate traffic visually. It is the responsibility of the pilot to see and maneuver to avoid traffic. NOTE: TIS is available only when the aircraft is within the service volume of a TIS-capable terminal radar 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. NOTE: TIS is disabled if a Traffic Advisory System (TAS) is installed. 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 G1000H displays up to eight traffic targets within a 7.5-nm radius, from 3000 feet below to 3500 feet above the requesting aircraft. Traffic is displayed using three different symbols (Table 6-12). TIS Symbol Description Non-Threat Traffic Traffic Advisory (TA) Traffic Advisory Off Scale Table 6-12 TIS Traffic Symbols A Traffic Advisory (TA) indicates that the current track of the intruder could result in a collision. When traffic meets the advisory criteria for the TA, a solid yellow circle symbol is generated. A TA which is detected, but is outside the range of the map, is indicated with a message in the lower left corner of the map and a half TA symbol at the relative bearing of the intruder. 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 6-88) or in a banner at the lower left corner of maps other than the Traffic Map Page on which traffic can be displayed (Figure 6-84). 190-01255-00 Rev.
