Altitude Reporting; Terrain 7; Weather 7; Nearest 7 - Garmin GTN 625 Pilot's Manual

9.3 Traffic Information Service (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 ownship 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 equipped aircraft, TIS, and Traffic Advisory System
(TAS) may not both be displayed at the same time.
NOTE: More information is available about the GDL 88 in the "Garmin
GDL 88 ADS-B Transceiver Pilot's Guide, P/N 190-01122-03."
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 3000 feet below to 3500 feet above the requesting aircraft.
