Garmin G900X Pilot’s Guide 190-00726-00 Rev. A6-42HAZARD AVOIDANCE6.4 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 G900X displays up to eight traffic targets within a 7.5-nm radius, from 3000 feet below to3500 feet above the requesting aircraft. Traffic is displayed according to TCAS symbology using four differentsymbols (Table 6-9).TIS Symbol DescriptionNon-Threat TrafficProximity Advisory (PA)Traffic Advisory (TA)Traffic Advisory Off ScaleTable 6-9 TIS Traffic SymbolsProximity Advisories (PAs) are defined as traffic within the 5.0-nm range, within ±1200 feet of altitude separation.They are not Traffic Advisories (TA), which alert the crew to intruding aircraft. When traffic meets the advisorycriteria for the TA, a solid yellow circle symbol is generated. A TA which is detected but is outside the range ofthe 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°. Trafficinformation for which TIS is unable to determine the bearing (non-bearing traffic) is displayed in the center ofthe Traffic Map Page (Figure 6-61) 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 as
