*All new G3X units, including Non-TSO remote-mount or Non-TSO panel-mount, are warranted to be
free from defects in materials or workmanship for the earlier of: 2 years or 800 flight hours from the date of
purchase.
NOTE: It is the responsibility of the GTX 330 owner to obtain proper licensing before using
the transponder.
NOTE: The coverage expected from the GTX 330 is limited to line of sight. Low altitude or
aircraft antenna shielding by the aircraft itself may result in reduced range. Range can be
improved by climbing to a higher altitude. It may be possible to minimize antenna shielding
by locating the antenna where dead spots are only noticed during abnormal flight attitudes.
The GTX 330 transponder is powered on by pressing the STBY, ALT or ON keys, or by a remote avionics master
switch (if applicable). After power on, a start-up page is displayed while the unit performs a self test.
Mode Selection Keys
OFF  Powers off the GTX 330. Pressing STBY, ON, or
ALT key powers on the transponder displaying the last
active identification code.
STBY  Selects the standby mode. When in standby mode,
the transponder will not reply to any interrogations.
ON  In this mode, the transponder replies to interrogations, as
indicated by the Reply Symbol ( ). Replies do not include altitude information.
ALT  In ALT mode, the transponder replies to identification and altitude interrogations
as indicated by the Reply Symbol ( ). Replies to altitude interrogations include the
standard pressure altitude received from an external altitude source, which is not adjusted
for barometric pressure. The ALT mode may be selected in aircraft not equipped with an
optional altitude encoder; however, the reply signal will not include altitude information.
Any time the function ON or ALT is selected the transponder becomes an active part of
the Air Traffic Control Radar Beacon System (ATCRBS). The transponder also responds to
interrogations from TCAS equipped aircraft.
NOTE: If Automatic Airborne Determination senses the aircraft is on the
ground, the GTX 330 will not respond to ATCRBS or Mode S All-Call interrogations regardless of the operating mode.
Code Selection
Code selection is done with eight keys (0 – 7) providing 4,096 active identification codes.
Pushing one of these keys begins the code selection sequence. Digits that are not yet entered
appear as dashes. The new code is activated when the fourth digit is entered. Pressing the CLR
key moves the cursor back to the previous digit. Pressing the CLR key when the cursor is on
the first digit of the code, or pressing the CRSR key during code entry, removes the cursor and
cancels data entry, restoring the previous code. You may press the CLR key up to five seconds
after code entry is complete to return the cursor to the fourth digit. The numbers 8 and 9 are not
used for code entry, only for entering a Count Down time, and for adjusting contrast and display
brightness.
When the transponder code is changed, a notification is sent to ATC by the GTX 330.
This notification is temporary and will not be sent if the GTX is inactive (i.e., set to STBY)
when the code is changed.
NOTE: On a dual transponder installation, change the code on the active
transponder. This ensures the notification is transmitted to ATC.
Keys for Other GTX 330 Functions
IDENT Pressing the IDENT key activates the Special Position
Identification (SPI) Pulse for 18 seconds, identifying your transponder
return from others on the air traffic controller’s screen. The word IDENT
will appear in the upper left corner of the display during this time.
VFR Sets the transponder code to the pre-programmed VFR code
selected during installation configuration (this is set to 1200 at the
factory). Pressing the VFR key again restores the previous identification
code. If the VFR Key is pressed when disabled (dependent upon
installation configuration) a VFR Key Disabled message appears to
indicate that no operation took place.
FUNC Changes the page shown on the right side of the display.
Display data includes Pressure Altitude, Flight Time, Altitude Monitor,
Count Up, and Count Down timers. Also displays Outside Air
Temperature, Density Altitude, Contrast, Display, and ADS-B Operation
(dependent upon installation configuration).
START/STOP Starts and stops the Altitude Monitor, Count Up,
Count Down, and Flight timers.
CRSR Initiates starting time entry for the Count Down timer and
cancels transponder code entry.
CLR Resets the Count Up, Count Down, and Flight timers. Cancels
the previous keypress during code selection and Count Down entry.
Returns cursor to the fourth code digit within five seconds after entry.
8 Reduces Contrast and Display Brightness when the respective fields
are displayed (dependent upon installation configuration) and enters
the number eight into the Count Down timer.
9 Increases Contrast and Display Brightness when the respective
fields are displayed (dependent upon installation configuration) and
enters the number nine into the Count Down timer.
Function Display
NOTE: GTX 330 options are normally set at time of installation. For changes
to the GTX 330 parameters, contact your Garmin authorized dealer.
FLIGHT ID: Displays the Flight ID. The CRSR key opens the Flight
ID entry dialog if the ‘ALLOW PILOT TO EDIT FLT ID’ option is enabled during installation configuration.
PRESSURE ALT: Displays the altitude data supplied to the GTX 330
in feet, hundreds of feet (i.e., flight level), or meters (dependent upon
installation configuration).
FLIGHT TIME: Timer start is configured as either Manual or Automatic. When Manual, displays the Flight Time, controlled by the
START/STOP and CLR keys. When Automatic, the timer begins when
takeoff is sensed.

ADS-B defaults to ON at each power cycle. ADS-B ON/OFF is controlled by the START/STOP key. Turn ADS-B OFF only at the request
of ATC. NO ADSB will appear in the upper left corner when ADS-B
is configured ON but cannot transmit the position of the aircraft, or
when ADS-B TX is manually turned OFF.
Altitude Trend Indicator
When the PRESSURE ALT page is displayed, an arrow may be displayed to the right of
the altitude, indicating that the altitude is increasing or decreasing. One of two sizes of arrows
may be displayed depending on the vertical speed rate. The sensitivity of these arrows is
initially set during transponder installation.
Timer Operation
To operate the Flight Timer:
1) Press the FUNC key until FLIGHT TIME is displayed.
2) If the GTX 330 is configured with Automated Airborne Determination, the timer begins
automatically when the unit senses that the aircraft has become airborne. The timer
may be reset to zero at every takeoff, continue accumulating time at takeoff, or may be
controlled manually.
3) If desired, press START/STOP to pause or restart the timer.
4) Press CLR to reset the timer to zero.
5) If the timer is configured to start automatically it will stop when the Automated Airborne
Determination senses that the aircraft is on the ground.
To operate the Count Up timer:
1) Press the FUNC key until COUNT UP is displayed.
2) If necessary, press CLR to reset the Count Up timer to zero.
3) Press START/STOP to begin count up.
4) Press START/STOP again to pause the timer.
5) Press CLR to reset the timer to zero.
To operate the Count Down timer:
1) Press the FUNC key until COUNT DOWN is displayed.
2) Press CRSR and use the 0 - 9 keys to set the initial time. All digits must be entered (use
the 0 key to enter leading zeros).
3) Press START/STOP to begin count down.
4) Press START/STOP again to pause the timer.
5) When the Count Down timer expires, the COUNT DOWN banner is replaced with a
flashing EXPIRED, the message “Timer Expired” is heard, and the time begins counting up.
6) Press CLR to reset the timer to the initial time value.
Automatic ALT Mode Switching
If the GTX 330 is configured for Automated Airborne Determination, the system
automatically switches to ALT Mode when takeoff is sensed.
NOTE: Automatic mode switching can be disabled in software version
8.03 and later by setting Auto-ALT to OFF during installation configuration.
Failure Annunciation
If the unit detects an internal failure or an ADS-B transmission failure, the screen displays
FAIL. When FAIL is annunciated no transponder data is transmitted.
Altitude Monitor Operation
To operate the Altitude Monitor:
1) Climb to assigned altitude.
2) Press the FUNC key until ALT MONITOR is displayed.
3) Press START/STOP key to start monitoring altitude.
4) Press START/STOP key again to cancel Altitude Monitor.
Altitude deviation is shown in hundreds of feet ABOVE or BELOW the selected altitude.
When the aircraft’s altitude exceeds the deviation limit, ABOVE or BELOW flashes and an
audio tone or the message “Leaving Altitude” is heard. ABOVE or BELOW flashes until the
aircraft returns to within 100’ of the selected altitude.
To select a new monitored altitude, press the START/STOP key to deactivate, then press
again to activate the new monitored altitude.
If another function is selected for viewing, such as a Timer or Pressure Altitude, the
Altitude Monitor is automatically displayed with a flashing alert when the altitude excursion
exceeds the configured deviation value. The Altitude Monitor stops when the current
deviation exceeds 1000 feet plus the configured deviation value.
The maximum configured deviation values that can be set by a Garmin authorized service
center are as follows:
Flight Level or Feet Maximum Limits – 300 feet BELOW, 0 feet to 1999 feet ABOVE
Meters Maximum Limits – 300 meters BELOW, 0 meters to 609 meters ABOVE
Mode S Data Transmission
In addition to 4096 code and pressure altitude, the GTX 330 is capable of transmitting
aircraft identification, transponder capability, and maximum speed range. Aircraft
identification is commonly referred to as FLT ID (Flight Identification). The GTX 330 may be
configured by the installer to allow the flight crew to enter FLT ID for each flight. An example
is when air-carrier service requires changing the FLT ID.
The FLT ID may consist of the aircraft registration or a flight number as agreed upon with
the local aviation authority. In either case, the FLT ID must be the same aircraft identification
that appears in the flight plan to correlate the aircraft identification seen on ATC radar with the
correct voice call sign for the aircraft. If no flight plan is filed with the aviation authority (as
may be permitted by regulations), the FLT ID entered is the aircraft registration marking.
When flight crew entry of the FLT ID is not required, the installer configures the system to
report the aircraft identification according to local aviation requirements. In this configuration,
alteration of the FLT ID by the flight crew is not possible.
Flight ID Entry Dialog
When ALLOW PILOT TO EDIT FLT ID is enabled at installation, the flight crew may
change the Flight ID after power up by navigating to the FLIGHT ID Page and pressing the
CRSR key. This opens the Flight ID Entry dialog. After the flight crew enters the correct
Flight ID, the aircraft identification that is transmitted in response to ATC radar interrogations
will properly correlate with the associated call sign for voice communication with the aircraft.
If ALLOW PILOT TO EDIT FLT ID is required but is disabled, contact a Garmin
authorized service center for GTX 330 configuration.
Flight ID Entry Dialog
Editing the Flight ID
When the Flight ID Entry dialog is displayed, press the CRSR key to begin editing the
Flight ID. To change a character, press the number keys corresponding to the alphanumeric
character entry. For example, to enter the letter R, press the 5 key four times. Each time an
alphanumeric character is entered, press the CRSR key to move the cursor to the next blank
field. Pressing the CLR key moves the cursor back to the previous character. Once the last
character is entered, press the CRSR key to move the cursor over the remaining blank fields to
complete Flight ID entry.
Editing the Flight ID
NOTE: No space is needed when entering Flight ID characters. When a
flight ID contains a space, the GTX 330 automatically removes the spaces
upon completion of Flight ID entry.
NOTE: If the entered Flight ID is blank (i.e. all spaces), the new Flight ID
will not be saved by the GTX 330 and the dialog will remain open.
If an error is made while entering a Flight ID, press the CLR key to back up to any point.
If the CLR key is pressed when the cursor is covering the first Flight ID character, the Flight
ID will revert to the last Flight ID entered, and the dialog will remain open. If the CLR key is
pressed when the Flight ID is not being edited, the dialog will close without saving.
When the transponder Flight ID is changed, a notification is sent to ATC by the GTX
330. This notification is temporary and will not be sent if the GTX 330 is inactive (i.e., set to
STBY).
NOTE: For dual transponder installations, change the Flight ID on the
active transponder. This ensures the notification is transmitted to ATC.
NOTE: The GTX 330 must be set to ON or ALT during a Flight ID change
in order for ATC to be notified of the change.
Resetting the Flight ID to Default
If a default Flight ID is configured, the Flight ID Entry dialog will display an option in the
lower right corner of the screen “8=<DEFAULT>”, where <DEFAULT> is the configured default
Flight ID. Press the 8 key to reset the Flight ID to this default and close the dialog. If a default
Flight ID is required but is not configured, contact a Garmin authorized service center for GTX
330 configuration.
GTX 330 Mode S Transponder Features
GTX 330D Diversity Mode S Transponder
The GTX 330D Diversity Mode S Transponder incorporates antennas mounted on the
top and bottom of the aircraft for dependable operation while maneuvering. Top and
bottom antennas are less prone to antenna shadowing by the aircraft structure while turning.
A top mounted antenna is in a better viewing position for interrogation and reply to overhead
aircraft.
Traffic Information Service
The GTX 330 Mode S transponder provides a data link for Traffic Information Service
(TIS). TIS is derived through a Mode S transponder data link and viewed on a multifunction
display. ATC radar sends a traffic picture within a radius of 55 miles from select sites. The
TIS protected area is a cylinder of 7-mile radius, extending 3500’ above and 3000’ below the
aircraft. Refer to the AIM Chapter 1 for more details.
TIS provides a graphic display of traffic information in the cockpit for non-TCAS equipped
aircraft. Transponder-equipped aircraft can be displayed within the coverage volume within
range of your position on indicators such as a Garmin GNS 430 or GNS 530, GTN 6XX/7XX,
GNS 480, and GMX 200. Aircraft without an operating transponder are invisible to TIS. Refer
to 400/500 series, GTN 6XX/7XX, GNS 480, or GMX 200 pilot literature for details.
GTX 330 ES Options
Automatic Dependent Surveillance-Broadcast (ADS-B) technology improves situational
awareness and flight safety. With ADS-B capabilities, position, velocity, and heading
information are automatically transmitted to other aircraft and ground stations. The current
air traffic control system depends on a transponder request for pertinent aircraft information
and does not include 3D position. ADS-B provides automatic transmission of aircraft
information without a request.
NOTE: The GTX 330 with software version 8.01 or later, has been shown
to comply with TSO-C166b and AC 20-165 and is eligible for use as an
ADS-B out Transmitter meeting the requirements of 14 CFR 91.225 and
91.227 when installed in accordance with Garmin’s installation instructions.
Refer to the AFMS for more information on your installation and whether
it is ADS-B version 2 compliant.
Audio Alerts
When connected to the aircraft audio system, the GTX 330 will emit important voice alerts
at relevant times. The alerts the GTX 330 will emit are:
• “Leaving Altitude” - Altitude Monitor deviation is exceeded.
• “Traffic” - TIS traffic alert is received.
• “Traffic Not Available” - TIS service is not available or out of range.
• “Timer Expired” - Count down time has expired.
To change the volume of the alerts, and toggle between male voice, female voice, or tone
alerts, refer to the installation guide.
