Tis Symbology - Garmin G1000 Pilot's Manual

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 3000 feet below to 3500 feet above the
requesting aircraft. Traffic is displayed according to TCAS symbology using four different symbols (Table 6-
12).
Proximity 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 advisory criteria for the TA, a solid yellow circle symbol is generated. TIS provides vector lines showing
the direction in which 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 arrow displays.
