Introduction
Warnings and Cautions
WARNING: Terrain data are obtained from third party sources. Garmin is not able to independently verify the accuracy of this
data which should be used only as an aid for situational awareness. Terrain data must not be used as the sole basis for decisions or maneuvers to avoid terrain or obstacles. Terrain data must not be used for navigation.
WARNING: Do not use data link weather information for maneuvering in, near, or around areas of hazardous weather. Information contained within data link weather products may not accurately depict current weather conditions.
WARNING: Do not use the indicated data link weather product age to determine the age of the weather information
shown by the data link weather product. Due to time delays inherent in gathering and processing weather data for data link
transmission, the weather information shown by the data link weather product may be significantly older than the indicated
weather product age.
CAUTION: Use the 400W/500W Series Units at your own risk. To reduce the risk of unsafe operation, carefully review and
understand all aspects of the Owner’s Manual and the Flight Manual Supplement, and thoroughly practice basic operation
prior to actual use.
CAUTION: The Global Positioning System is operated by the United States government, which is solely responsible for its
accuracy and maintenance. The system is subject to changes which could affect the accuracy and performance of all GPS
equipment. Although Garmin 400W/500W Series Units are precision electronic NAVigation AIDS (NAVAID), any NAVAID can be
misused or misinterpreted and therefore become unsafe.
CAUTION: The Jeppesen database incorporated in the Garmin 400W/500W Series Units must be updated regularly in order to
ensure that its information is current. Updates are released every 28 days. A database information packet is included in your
Garmin 400W/500W Series Unit package. Pilots using an out-of-date database do so entirely at their own risk.
CAUTION: The Weather Data Link, TIS, TAWS, HTAWS, and TERRAIN information contained in this Pilot’s Guide Addendum is
not intended to replace the documentation that is supplied with the applicable Garmin 400W/500W Series Unit and the GTX
330 Transponder. The user must know how to operate the 400W/500W Series Unit and be knowledgeable of the information in
the 400W/500W Pilot’s Guide.
TIS CAUTION: TIS is NOT intended to be used as a collision avoidance system and does not relieve pilot responsibility to “see
and avoid” other aircraft. TIS should not be used for avoidance maneuvers during IMC or other times when there is no visual
contact with the intruder aircraft. TIS is intended only to assist in visual acquisition of other aircraft in VMC. Avoidance maneuvers are not recommended, nor authorized, as a direct result of a TIS intruder display or TIS alert.
While TIS is a useful aid to visual traffic avoidance, it has some system limitations that must be fully understood to ensure
proper use. Many of these limitations are inherent in secondary radar surveillance. In other words, the information provided by
TIS will be no better than that provided to ATC.
NOTE: Do not rely solely upon data link services to provide Temporary Flight Restriction (TFR) information. Always confirm
TFR information through official sources such as Flight Service Stations or Air Traffic Control.
NOTE: For software version 4.00 and later: when configured for helicopters (the helicopter icon will be displayed), black, circular or oblong “cutouts” will be displayed on the Terrain Page around airports and heliports, to enhance viewing of the information displayed for those locations. The Terrain legend (shown in the lower right of the display on the Terrain Page) defines the
color black as -500 ft. However, this does not apply to the black cutouts surrounding the airports and heliports. The cutouts are
for display purposes only and do not affect the performance of HTAWS.

TIS Operation
NOTE: Part One of this Addendum assumes the
user has experience operating the 400W/500W
Series units and the Garmin GTX 330 Transponder.
The Traffic Information Service (TIS) provides a graphic
display of traffic advisory information in the cockpit for
non-TCAS (Traffic alert and Collision Avoidance System)
equipped aircraft. TIS is a ground-based service providing
relative location of all ATCRBS (Air Traffic Control Radar
Beacon System) Mode A and Mode C transponderequipped aircraft within a specified service volume. The
TIS ground sensor uses real-time track reports to generate
traffic notification. TIS Traffic display is available to
aircraft equipped with a Mode S Data Link such as the
Garmin GTX 330 Transponder. TIS Traffic from a GTX
330 Transponder can then be displayed on a Garmin
400W/500W Series unit. Surveillance data includes
all transponder-equipped aircraft within the coverage
volume. Aircraft without an operating transponder are
invisible to TIS. TIS displays up to eight traffic targets
within seven nautical miles horizontally from 3000 feet
below to 3500 feet above the requesting aircraft.
• The “intruder” aircraft must be within the TIS
• Both your aircraft and the intruder aircraft must

How TIS differs from TCAS
The main difference between TIS and TCAS is the
source of surveillance data. TCAS uses an airborne
interrogator with a one-second update rate, while TIS uses

radar antenna, the signal may be temporarily interrupted.
Other limitations and anomalies associated with TIS are
described in the AIM, Sections 4-5-6 and 4-5-8.
the terminal Mode S ground interrogator and its Data Link
to provide about a five-second update rate. The range
accuracy of TIS and TCAS is similar.
TIS Limitations
NOTE: This section on TIS Limitations is not com-
prehensive. Garmin recommends the user review
the TIS Limitations section of the Aeronautical
Information Manual, Sections 4-5-6 and 4-5-8.
TIS is NOT intended to be used as a collision avoidance
system and does not relieve the pilot of responsibility to
“see and avoid” other aircraft. TIS should not be used for
avoidance maneuvers during IMC or other times when
there is no visual contact with the intruder aircraft. TIS
is intended only to assist in visual acquisition of other
aircraft in VMC. No recommended avoidance maneuvers
are provided for, nor authorized, as a direct result of a TIS
intruder display or TIS advisory.
TIS information is collected one radar scan prior to
While TIS is a useful aid to visual traffic avoidance, it
has some system limitations that must be fully understood
to ensure proper use. Many of these limitations are
inherent in secondary radar surveillance. In other words,
the information provided by TIS will be no better than
that provided to ATC. TIS will only display aircraft with
operating transponders installed.
TIS relies on surveillance of the Mode S radar, which
is a “secondary surveillance” radar similar to the ATCRBS.
TIS operation may be intermittent during turns or other
maneuvering. TIS is dependent on two-way, “line-ofsight” communication between the aircraft and the Mode
S radar. Whenever the structure of the client aircraft
comes between the transponder antenna (usually located

the scan during which the uplink occurs. Therefore, the
surveillance information is approximately five seconds old.
In order to present the intruders in a “real time” position,
the TIS ground station uses a “predictive algorithm” in its
tracking software. This algorithm uses track history data to
extrapolate intruders to their expected positions consistent
with the time of display in the cockpit. Occasionally,
aircraft maneuvering will cause this algorithm to induce
errors in the 400W/500W display. These errors primarily
affect relative bearing information and traffic target track
vector (it will lag); intruder distance and altitude will
remain relatively accurate and may be used to assist in
“see and avoid.” Some of the more common examples of
these errors follow:
Garmin is not responsible for Mode S geo-
graphical coverage. Operation of the ground
stations is the responsibility of the FAA. Refer
to the Aeronautical Information Manual for a
Terminal Mode S Radar Site Map covering the
U.S.
NOTE: TIS will be unavailable at low altitudes in
many areas of the U.S., particularly in mountainous regions. Also, when flying near the “floor”
of radar coverage in a particular area, intruders
below the client aircraft may not be detected by
TIS.
Part One: Section 1
TIS Operation and Symbology
• When client or intruder aircraft maneuvers exces-
sively or abruptly, the tracking algorithm may
report incorrect horizontal position until the
maneuvering aircraft stabilizes.
• When a rapidly closing intruder is on a course that
crosses the client aircraft course at a shallow angle
(either overtaking or head on) and either aircraft
abruptly changes course within ¼ NM, TIS may
display the intruder on the opposite side of the
client than it actually is.
These are relatively rare occurrences and will be
corrected in a few radar scans once the course has
stabilized.
TIS Symbology
TIS traffic is displayed on the 400W/500W Series unit
according to TCAS symbology, graphically displayed on
a dedicated graphical page (Traffic Page; see below), and
on the moving Map Page. A Traffic Advisory (TA) symbol
appears as a solid yellow circle (or half circle on the outer
range ring if the traffic is outside the range of the dedicated
Traffic Page). Proximity Advisories (PA) are displayed as a
solid diamond, and other traffic is displayed as an open
diamond. PA and other traffic is normally displayed in
white, or it may be alternatively configured for display
in cyan. When configured for cyan, the traffic page range
rings and markings are displayed in white. Altitude
deviation from own aircraft altitude is displayed above the
Improving TIS
Users of TIS can render valuable assistance in the
correction of malfunctions by reporting their observations
of undesirable performance. Reporters should identify
the time of observation, location, type and identity of
aircraft, and describe the condition observed; the type
of transponder processor and software in use can also be
useful information. Since TIS performance is monitored

below the symbol if they are below own aircraft altitude.
Altitude trend is displayed as an up arrow (> +500 ft/min),
down arrow (< -500 ft/min), or no symbol if less than 500
ft/min rate in either direction.

Part One: Section 1
TIS Operation and Symbology
The TIS audio alert is generated from the
GTX 330 whenever the number of Traffic Advisories on the 400W/500W display increases
from one scan to the next. Limiting Traffic
Advisories only reduces the “nuisance” alerting
due to proximate aircraft. For example, when
the first Traffic Advisories appears on the TIS
display, the user is alerted audibly. So long as
a single aircraft remains on the TIS display, no
further audio alert is generated. If a second (or
more) aircraft appears on the display, a new
audio alert is sounded.
If the number of Traffic Advisories on the TIS
display decreases and then increases, a new
audio alert is sounded. The TIS audio alert is
also generated whenever TIS service becomes
unavailable. The volume, pitch, and duration
of the audio alert (including the choice between
a male or female voice) is configured during
installation.
The following TIS audio alerts are available:
• “Traffic” —TIS traffic alert is received.
• “Traffic Not Available” — TIS service is not
available or out of range.

TIS Operational Procedures
Section 3: TIS Operational Procedures
Introduction
TIS warns the user with voice and visual traffic
advisories whenever it predicts an intruder to be a threat
(see illustration). Voice and visual data are sent from the
GTX 330. The user should not start evasive maneuvers
using information from the 400W/500W display or on
a traffic advisory only. The display and advisories are
intended only for assistance in visually locating the traffic,
due to the lack in resolution and coordination ability. The
flight crew should attempt to visually acquire the intruder
aircraft and maintain a safe separation in accordance with
the regulatory requirements and good operating practice.
If the flight crew cannot visually acquire the aircraft, they
should contact ATC to obtain any information that may
assist concerning the intruder aircraft. Based on the above
procedures, minor adjustment to the vertical flight path
consistent with air traffic requirements are not considered
evasive maneuvers.
Power-Up Test
The TIS interface performs an automatic test during
power-up.
• UNAVAIL — When a 60 second period elapses
GTX 330 has failed. The “DATA FAIL” message
indicates data are being received from the GTX
330 but a failure was detected in the data stream.
The “NO DATA” message indicates that data are
not being received from the GTX 330.
NOTE: “NO DATA” may be a normal mode of
operation in a dual transponder installation
where the GTX 330 with TIS is not the selected
transponder.
with no data, TIS is considered to be unavailable.
This state is indicated by the text “UNAVAILABLE”
(500W Series) and “UNAVAIL” (400W Series).
The pilot should be aware that “UNAVAIL” could
indicate a TIS coverage limitation due to a line-ofsight situation, a low altitude condition, no TIS
service, or a result of flying directly over the radar
site providing coverage (cone of silence).

1. Turn the cursor on and highlight “OPER”.
2. Turn the small right knob to select “STBY?”
3. Press ENT to confirm.
“DATA FAIL” Message
The “NO DATA” message indicates that data
are not being received from the GTX 330.
NOTE: This may be a normal mode of opera-
tion in a dual transponder installation where
the GTX 330 with TIS is not the selected
transponder.
Flight Procedures
Once the aircraft is airborne (determined by system
configuration at the time of installation) the system
switches from standby mode to operating mode. The
400W/500W Series unit displays OPER in the upper right
hand corner of the display and begins to display traffic on
the Traffic or Map Page.
The TIS Traffic Advisory (TA) should alert the crew to
use additional vigilance to identify the intruding aircraft.
Any time the traffic symbol becomes a yellow circle or a
voice warning is announced, conduct a visual search for
the intruder. If successful, maintain visual contact to ensure
safe operation. See Section 2: Control and Display for a
description of pilot responses to TIS display messages.
After Landing
10
Once the aircraft is “ground-borne” (determined by
system configuration at the time of installation) the system
switches from operating mode to standby mode. The
400W/500W Series unit displays “STBY”. As described
previously, both the standby and operating modes can be
manually overridden by the display controls.

XM Radio Interface
Section 1: Introduction
Overview
The GDL 69 is a remote sensor that receives
broadcast weather data from a data service of SiriusXM
Satellite Radio Inc. The GDL 69A is similar to the GDL
69, but also receives audio entertainment broadcasts from
another service of SiriusXM Satellite Radio. The 400W
and 500W series units serve as the display and control
head for your remotely mounted GDL 69/69A radio.
Before the GDL 69/69A can be used, the unit must
be activated by SiriusXM Satellite Radio with a service
subscription through SiriusXM Satellite Radio. Please note
that the GDL 69 is a weather data link. The GDL 69A is a
weather data link and audio receiver. The data link service
and the audio entertainment services must be activated
separately.
Your GDL 69 or GDL 69A is shipped with one or two
radio hardware identifications, respectively. These IDs
serve as identification codes for your SiriusXM Satellite
Radio-equipped GDL 69/69A and are needed in the
activation process. The ID(s) is (are) attached to the
Activation Instructions and printed on a label on the back
of the unit. The IDs can also be retrieved through your
unit in the SiriusXM Satellite Radio Information page of
the Aux function. Contact your dealer or customer service
if you are unable to locate the radio hardware IDs.
Weather and/or audio data from your GDL 69/69A are
provided by SiriusXM Satellite Radio, a company separate
and independent from Garmin Corporation. Have your
radio hardware IDs ready before contacting SiriusXM
Satellite Radio. During the process, you can select services
for subscription. Keep in mind that the GDL 69 has no audio
capability, audio services will not be available with the unit.

XM WPT Pages
When a GDL 69 or GDL 69A is installed, two SiriusXM
Weather-related pages are added to “airport” pages in the
WPT page group:
• Textual METAR Page. The Textual METAR
page shows the text of the most recent METAR
(Meteorological Aerodrome Report) that has been
received for an airport.
• TAF Page. The TAF page shows the text of the
most recent TAF (Terminal Aerodrome Forecast)
that has been received for an airport.
XM AUX Pages
When a GDL 69 or GDL 69A is installed, the following
XM pages appear in the AUX group of pages:
• XM Audio Page (GDL 69A only). See Section 4
below for a description of this page.
• XM Information Page. This page contains infor-
mation that you will use when activating your XM
satellite radio subscription. It also reports the GDL
69/69A’s software version number. SiriusXM Satellite Radio and SiriusXM Weather subscriptions are
sold separately.
• XM Weather Timestamp Pages. This page show
timestamp data for the most recently received XM
weather data.
Section 2: SiriusXM Weather
The SiriusXM Weather Function is capable of displaying
graphical weather information through the SiriusXM
Satellite Radio Service when activated in the optional
installation of the GDL 69/69A. Next Generation Weather
Radar (NEXRAD), METARs symbols (METAR), Lightning
(LTNG), Cell Movement (CELL MOVE), and Winds Aloft
(WINDS) are displayed on the NAV pages. The types of
products available depend on the subscription service
with XM Satellite Radio.
Once you have activated an aviation weather service
from SiriusXM Weather, the 400W/500W series unit can
display the following aviation-related data:
• NEXRAD. An indication of the intensity of
weather radar echoes from the National Weather
Service’s network of NEXRAD (NEXt generation
RADar) sites can be shown on the SiriusXM
Weather Page and can optionally be overlaid on
the Map page. (Both these pages are in the NAV
page group.) Canadian Radar may also be available.
• Radar Coverage. Whenever NEXRAD is shown, a
cross-hatch pattern indicates the limits of NEXRAD
radar coverage. The cross-hatched area shows
where NEXRAD information is unavailable.
• Lightning (LTNG). When enabled, lightning
strikes and cells are shown as yellow “+” signs.
Lightning information indicates the location of
cloud-to-ground lightning strikes.
12
• Cell Movement (CELL MOVE). When enabled,
Cell Movement shows the storm cells identified
by the ground-based system. The movement
is depicted by an arrow. The tip of the arrow
represents where the cell is expected to be in
10 minutes from the time the cell location was
determined.

• Winds Aloft (WINDS). The Winds Aloft
selection provides the pilot with wind speed
and direction. The winds at a given altitude
are selected in the Winds Aloft Alt below the
WINDS selection. The selected altitude is shown
along with the product time.
• Textual Meteorological Aerodrome Reports
(METARs). When you zoom in to show the airport symbol associated with the colored flag for a
graphical METAR, and move the Map Pointer to
highlight that airport, you can then press ENT to
see the Textual METAR page for that airport. The
Textual METAR page is one of the airport pages
of the WPT page group.
• Graphical Meteorological Aerodrome Reports
(METARs). The XM Weather page (in the NAV
page group) can show colored flags to indicate
the level of current weather conditions at those
airports for which textual METAR reports are
available. The flags are color-coded to indicate
the severity of the current weather at the airport:
cyan for VFR conditions, green for Marginal VFR
conditions, yellow for IFR conditions, or magenta
of Low IFR conditions.
• Terminal Aerodrome Forecast (TAFs). A TAF
page is added among the airport pages of the
WPT page group. The TAF page differs from the
Textual METAR page in that it describes forecast
future weather conditions rather than current
conditions.
• Temporary Flight Restrictions (TFRs). The
boundaries of areas with TFRs are outlined in
yellow on the Map and XM Weather pages of
the NAV page group. In the 500W-series, TFR
boundaries are also shown on the NAV main
page. You can obtain more information about a
190-00356-30 Rev L
TFR by bringing up the map cursor, moving the
map cursor to within the yellow outlined area,
and pressing the ENT key.
Weather Product Age
The age of the displayed weather product—or the
effective time of Winds Aloft predictions—is shown in the
upper right corner of the display. For example, if NEXRAD
is displayed, “0:05” indicates that the data are five minutes
old. If Winds Aloft predictions are being displayed, “10:00”
indicates the effective time for the displayed prediction is
10:00 AM.
The data for each XM Weather product are updated
regularly from the GDL 69/69A. XM Weather products
expire after the following intervals:
Product Expiration Interval
METARs 90 minutes
NEXRAD/Radar Coverage 30 minutes
TFRs 60 minutes
TAFs 60 minutes
Lightning 30 minutes
SCITs 30 minutes
Winds Aloft Predictions 90 minutes
When the age of the displayed XM Weather product
reaches one half of its expiration time, the color of the
displayed time changes from green to amber. Expired XM
Weather products are never displayed. In the unlikely
event that the data should expire before a fresh update
is received, the time will be dashed out and the data
removed from the display.
NOTE: Product age for individual reports of
XM AIRMETs, SIGMETs, City Forecasts, County
Warnings, Cell Movement and TFRs are not
provided by XM Weather Service.

strong). So, a more convenient number for calculations
and comparison, a decibel (or logarithmic) scale (dBZ), is
used. The dBZ values increase as the strength of the signal
returned to the radar increases. There are seven gradations

NEXRAD Limitations
Certain limitations exist regarding the NEXRAD
radar displays. Some, but not all, are listed for the user’s
awareness:
• NEXRAD base reflectivity does not provide suf-
ficient information to determine cloud layers or
precipitation characteristics (hail vs. rain, etc).
• NEXRAD base reflectivity is sampled at the
minimum antenna elevation angle. An individual
NEXRAD site cannot depict high altitude storms
at close ranges, and has no information about
storms directly over the site.
• Neither NEXRAD weather data nor the age of the
NEXRAD weather data are displayed at a zoom
range of less than 10 NM. The resolution of displayed NEXRAD data is 2 kilometers. Therefore,
when zoomed in on the display, each square block
is 2 kilometers. The intensity level reflected by the
square will be the highest level sampled within
the 2 kilometer square area.

“Natural Disaster,” and “Sports Event.”
• Facility/NOTAM. This filed contains a code
for the name of the FAA facility that issued the
NOTAM (Notice to Airmen) announcing the TFR,
followed by the NOTAM number. For instance,
“ZSE 6/9507” would mean NOTAM number
6/9507 from the Seattle ARTCC (KZSE).
NOTE: The full text of the NOTAM may be
obtained from a local FSS or from the FAA web

• Audio Signal. The Audio Signal field indicates the
signal strength of the GDL 69A’s audio signal. (In
the case of a GDL 69, this field shows “antenna”
rather than a signal strength indication.)

indication of the XM data signal strength.
• Service Class. Once you have activated your
SiriusXM Satellite Radio service, the Service Class
field will show the XM subscription plan you have
purchased. Typical values would be “Aviator LT” or
“Aviator.” Currently, the 400W and 500W-series
only support a subset of the Aviator LT service
from SiriusXM Satellite Radio.
NOTE: If an unrecognized service class is
detected, “Activated” will be displayed along
