190-00709-05 Rev. D Garmin G1000 Pilot’s Guide for the Socata TBM 850/900467HAZARD AVOIDANCE6.9 TRAFFIC INFORMATION SERVICE (TIS)WARNING: The Traffic Information Service (TIS) is intended for advisory use only. TIS is intended to help thepilot 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 radarsite. 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 descentindication.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 theMode S transponder for the traffic data link. TIS receives traffic information from ground stations, and is updatedevery 5 seconds. The G1000 displays up to eight traffic targets within a 7.5-nm radius, from 3000 feet belowto 3500 feet above the requesting aircraft. Traffic is displayed according to Traffic Alert and Collision AvoidanceSystem (TCAS) symbology.TIS Symbol DescriptionNon-Threat TrafficTraffic Advisory (TA)Traffic Advisory Off ScaleTable 6-27 TIS Traffic SymbolsA Traffic Advisory (TA) indicates that the current track of the intruder could result in a collision. When trafficmeets the advisory criteria for the TA, a solid yellow circle symbol is generated. A TA which is detected, but isoutside the range of the map, is indicated with a message in the lower left corner of the map and a half TA symbolat 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°. Trafficinformation for which TIS is unable to determine the bearing (non-bearing traffic) is displayed in the center of theTraffic Map Page (Figure 6-167) or in a banner at the lower left corner of maps other than the Traffic Map Pageon which traffic can be displayed.The altitude difference between the requesting aircraft and other intruder aircraft is displayed above/below thetraffic symbol in hundreds of feet. If the other aircraft is above the requesting aircraft, the altitude separationappears above the traffic symbol; if below, the altitude separation appears below. Altitude trend is displayed asan up/down arrow (for speeds greater than 500 fpm in either direction) to the right of the target symbol. Trafficsymbols for aircraft without altitude reporting capability appear without altitude separation or climb/descentinformation.
