HAZARD AVOIDANCE
TIS SYMBOLOGY
Traffic Information Service (TIS) is designed to help pilots detect and avoid aircraft intersecting their flight
path. TIS uses the Mode S transponder for the traffic data link.
TIS receives traffic information from ground stations and provides a five-second update rate. The G1000
displays up to eight traffic targets within a 7.5 nm radius, from 3,000 feet below to 3,500 feet above the
requesting aircraft. Traffic is displayed on the Traffic Map Page according to TCAS symbology. Traffic is
displayed using four different symbols (Table 6-14).
TIS Symbol Description
Non Threat Traffic
Proximity Advisories (PA)
Traffic Advisories (TA)
Traffic Advisory Off Scale
Table 6-12 Additional System Annunciations
Proximity Advisories (PAs) are defined as traffic within the 5.0-nm range, within ±1200 ft. of altitude
separation. They are not Traffic Advisories (TA). When traffic meets the advisory criteria for the TA a solid
yellow circle symbol is generated. TIS provides vector lines showing the direction that the aircraft symbol is
moving.
Deviation from aircraft altitude is displayed above or below the target symbol, depending on the traffic
location. Altitude trend is displayed as an up (+500 ft/min) or down (-500 ft/min) arrow to the right of the
target symbol. If the altitude trend is less than 500 ft/min rate in either direction, no symbol displays.
