TRAFFIC INFORMATION
SERVICE
The TIS provides the pilot with limited information
about nearby potential air-traffic hazards
in terminal areas that have TIS-capable
ground-based radar.
NOTE
TIS is an advisory service only, to
help the pilot locate traffic visually.
It is the pilot responsibility to see and
avoid traffic.
The service has three basic requirements:
• TIS-equipped aircraft must have an operating
mode-S transponder (the G1000
includes two).
• Conflicting aircraft must have an operating
mode-A, mode-C or mode-S
transponder.
• Both aircraft must be within range (approximately
55 miles) of an air traffic
control radar that has TIS enabled. These
radars are most likely to be in congested
terminal areas. (Refer to the FAA
Airman’s Information Manual for current
TIS-radar coverage status).
The ground-based radar, when providing TIS,
detects transponder-operating aircraft that are
in proximity to other aircraft, and transmits
traffic information about those aircraft to other
aircraft nearby. If the client aircraft are operating
a mode-S transponder, ground radar
transmits the location, direction, speed, and
vertical proximity of the other nearby aircraft.
Ground radar only reports a maximum of eight
traffic hazards, primarily those within 7 NM
horizontally and+3,500/–3,000 feet vertically
of the client aircraft.
The mode-S transponder receives this information,
and depicts it on the TRAFFIC display
of the MFD map and the PFD inset map.
Traffic Information Service is only
effective when within range of a TIScapable
terminal radar site. It may
operate intermittently, or not at all
due to interference with transmission
or reception (by obstacles, terrain
or the aircraft itself, or condition
of the ground radar). TIS does not
provide information on aircraft without
an operating transponder.
TIS is a “line-of-sight” system that uses tracking
to report and update traffic notifications
(every 5 seconds) on the MFD traffic map
page or on the PFD map inset. Traffic alert
messages appear on the PFD to the right of the
top of the airspeed tape.
The GTX 33 transponder has selective addressing
or MODE SELECT (mode-S) capability.
Mode-S functions include a data link
capability that allows information to be exchanged
between aircraft and various air traffic
control facilities.
TIS uses data acquired by surveillance of
the mode-S radar system. During turns or
other maneuvering, TIS data may become
random as a result of interference between
aircraft and ground antennae. Additionally,

reception may be interrupted by terrain (e.g.
mountains).
TIS performs an automatic test during powerup
and displays a standby screen on the traffic
map page. If the power-up test fails, a NO
DATA, DATA FAILED or FAILED message
displays on the second page in the map group.
The traffic map page displays the following
TIS information:
• Interrogating aircraft location, surrounding
traffic locations, and range marking
rings
• Current traffic mode (OPERATE,
STANDBY)
• Traffic alert messages (FAILED, DATA
FAILED, NO DATA, UNAVAILABLE)
• Traffic display banner (AGE, TRFC
COAST, TA OFF Range, TRFC RMVD,
TRFC FAIL, NO TRFC DATA, TRFC
UNAVAIL, TRAFFIC)
When the aircraft is airborne, TIS switches from
standby to operating mode. TIS OPERATING
displays in the upper left corner of the traffic map
page. A traffic advisory (TA) symbol displays
when traffic is within the following range:
• ±500 feet
• 0.5 NM
• 34 seconds
A traffic advisory is accompanied by an aural
“traffic” callout as well as when traffic becomes
unavailable. In addition, an alert box appears on
the PFD and the inset map is automatically displayed
with traffic information.
Altitude deviation from the interrogating aircraft
is shown above or below the target symbol.
Target climb or descent is shown as an up
or down arrow.
TIS assists pilots in the visual acquisition of
other aircraft in visual meteorological conditions
only. Do not use as a collision avoidance
system. Pilots still have “see and avoid” responsibility
