9.3 TIS (Optional)
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 and Traffic Advisory System (TAS) may not both be configured
at the same time.
NOTE: GDL 88 equipped aircraft only: When the radio tower symbol is
crossed out, the aircraft is not a participant in the TIS-B system – i. e. not
visible to other TIS-B clients. The GDL 88 will, however, continue to receive
available TIS-B and FIS-B ground station up-links and continue to display
TIS-B and FIS-B data along with available ADS-B and ADS-R data.
NOTE: Except for GDL 88 or GTX 345 equipped aircraft, TIS, and Traffic
Advisory System (TAS) may not both be displayed at the same time.
NOTE: For more information about the GDL 88, refer to the
"GDL 88 ADS-B Transceiver Pilot's Guide." For information about the
GTX 345, refer to the "GTX 335/345 Pilot's Guide."
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
five seconds. The GTN 6XX 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.
