The screen display examples shown in this

addendum are taken from the GNS 430W
and GNS 530W. TIS and Weather Data Link
Display Interface functionality is the same

for the 400W and 500W Series Units. TIS

Traffic Display and Weather Data Link are
available only when the 400W/500W units

are configured with the GTX 330 Mode S

Transponder and GDL 69/69A Data Link

Transceiver, respectively.

Introduction

Warnings and Cautions

WARNING: Terrain data is 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.

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: Use the Weather Data Link Interface, TIS, TAWS, and TERRAIN at your own risk. To reduce the risk of unsafe opera­tion, thoroughly practice basic operation prior to actual use. When in actual use, carefully compare indications from the
Garmin unit to all available navigation sources, including the information from other NAVAIDS, visual sightings, charts, etc.
For safety, always resolve any discrepancies before continuing navigation. The GPS altitude format calculated by the Garmin
400W/500W Series units is geometric height above mean sea level and could vary significantly from altitude displayed by pres­sure altimeters in aircraft. Never use GPS altitude to determine aircraft altitude.

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 Pilots using an out-of-date database do so entirely at their own risk.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, 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.

CAUTION: Garmin would like to remind pilots flying with GDL 69/69A-equipped aircraft that TFRs are only advisory and
are not a replacement for a thorough preflight briefing on TFR times and locations. Always confirm TFR data through official
sources and contact your Flight Service Station for interpretation of TFR data.

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 ground­based service providing relative location of all ATCRBS
(Air Traffic Control Radar Beacon System) Mode A
and Mode C transponder-equipped 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 transponder­equipped 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

Always remember that TIS cannot alert you to
the presence of aircraft that are not equipped with
transponders, nor can it alert you to aircraft that may
be nearby, but obscured from the ground surveillance

the ground.

TIS Coverage Volume (not to scale)

The TIS is a ground-based service that displays
nearby aircraft on your 400W/500W-series display.
For the TIS feature to inform you of a nearby aircraft’s
presence, several conditions must be met:

Part One: Section 1

TIS Operation and Symbology

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 the terminal Mode S ground interrogator and its
Data Link to provide about a five-second update rate.

of the client aircraft comes between the transponder
antenna (usually located on the underside of the air­craft) and the ground-based radar antenna, the signal
may be temporarily interrupted. Other limitations and
anomalies associated with TIS are described in the
AIM, Section 1-3-5.

The range accuracy of TIS and TCAS is similar.

TIS Limitations

NOTE: This section on TIS Limitations is not compre­hensive. Garmin recommends the user review the TIS
Limitations section of the Aeronautical Information
Manual, Section 1-3-5.

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.

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-of-sight” communication between the
aircraft and the Mode S radar. Whenever the structure

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

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.

TIS information is collected one radar scan prior to

and avoid.” Some of the more common examples of
these errors follow:

• 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.

Improving TIS

Part One: Section 1

TIS Operation and Symbology

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 by maintenance personnel
other than ATC, it is suggested that malfunctions be
reported in the following ways:

• By telephone to the nearest Flight Service Station

(FSS) facility.

• By FAA Form 8000-7, Safety Improvement Report,

a postage-paid card designed for this purpose.
These cards may be obtained at FAA FSSs, General
Aviation District Offices, Flight Standards District
Offices, and General Aviation Fixed Based Opera­tions.

TIS Operation and Symbology

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).
All other traffic is displayed as a hollow white dia­mond. Altitude deviation from own aircraft altitude
is displayed above the target symbol if traffic is above
own aircraft altitude, and below the symbol if they are

The TIS audio alert is generated from the

GTX 330 whenever the number of Traffic Advi-

sories 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:

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 is 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.

• UNAVAIL — When a 60 second period

is displayed. The “FAILED” message indicates
the GTX 330 has failed. The “DATA FAIL” mes­sage indicates data is being received from the
GTX 330 but a failure was detected in the data
stream. The “NO DATA” message indicates that
data is 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.

elapses with no data, TIS is considered to be
unavailable. This state is indicated by the text
“UNAVAILABLE” (500W Series) and “UNAVAIL”

that “UNAVAIL” could indicate a TIS coverage
limitation due to a line-of-sight situation, a low
altitude condition, no TIS service, or a result
of flying directly over the radar site providing
coverage (cone of silence).

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.

“DATA FAIL” Message

After Landing

Once the aircraft is “groundborne” (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.

Section 1: Introduction

Overview

The GDL 69 is a remote sensor that receives
broadcast weather data from a data service of XM Sat­ellite Radio, Inc. The GDL 69A is similar to the GDL
69, but also receives audio entertainment broadcasts
from another service of XM Satellite Radio. The 400W
and 500W series units serve as the display and control
head for your remotely mounted GDL 69/69A satellite
radio.

Before the GDL 69/69A can be used, the unit
must be activated by XM Satellite Radio with a service
subscription through XM 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 XM­equipped 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 XM 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 XM Satellite Radio, a company
separate and independent from Garmin Corporation.
Have your radio hardware IDs ready before contact­ing XM 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
