1. GENERAL DESCRIPTION

1.1 INTRODUCTION

This manual describes the physical, mechanical, and electrical characteristics and the installation requirements for the GTX 330 Mode S Transponder and GTX 330D Diversity Mode S Transponder. In this manual, the term GTX 330 applies to both transponders unless otherwise stated. Information pertaining to the maintenance, alignment, and procurement of replacement parts is found in the GTX 330 Maintenance Manual, P/N 190-00207-05. After installation of the GTX 330, FAA Form 337 must be completed by an appropriately certificated agency to return the aircraft to service.

1.2 EQUIPMENT DESCRIPTION

The Garmin GTX 330 is a panel mounted Mode S Transponder with the addition of timers, altitude reporting, mode S interrogation and reply, and multiple transmit/receive ARINC 429 and RS232 data ports. The Mode S transponder has the capability to transmit a unique address for every aircraft.

The GTX 330 is a radio transmitter and receiver that operates on radar frequencies, receiving ground radar or TCAS interrogations at 1030 MHz and transmitting a coded response of pulses to ground-based radar on a frequency of 1090 MHz. The GTX 330 is equipped with IDENT capability that activates the Special Position Identification (SPI) pulse for 18 seconds.

As with other Mode A/Mode C transponders, the GTX 330 replies with any one of 4,096 codes, which differ in the position and number of pulses transmitted. By replying to ground transmissions or TCAS interrogations, the GTX 330 enables ATC to display aircraft identification, altitude and ground speed as well as identification numbers on ATC radar screens or TCAS traffic indicators.

The GTX 330 is configured with all key controls. The layout of the front panel keys and displays segregates the transponder’s primary functions from the secondary functions. The unit can be configured so the aircraft avionics master bus can turn the unit on.

1.3 INTERFACE SUMMARY

The GTX 330 provides the following interface connections via the rear connector:

• Ten (10) encoding altimeter inputs.

• External IDENT input.

• External STBY input.

• External suppression pulse input.

• Switched power output of up to 1.5 amps (for digital altitude encoder power).

2. INSTALLATION

2.1 INTRODUCTION

This section provides the necessary information for installing the GTX 330 Mode S Transponder, and where required, optional accessories. Installation of the GTX 330 will differ according to equipment location and other factors. Cabling will be fabricated by the installing agency to fit these various requirements. Appendix B contains interconnect wiring diagrams, mounting dimensions, and information pertaining to installation. Each installation shall be accomplished to meet the requirements of FAA AC 43.13-2A.

2.2 UNPACKING AND INSPECTING EQUIPMENT

Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred during shipment. If the unit is damaged, notify the carrier and file a claim. To justify a claim, save the original shipping container and all packing materials. Do not return the unit to GARMIN until the carrier has authorized the claim.

Retain the original shipping containers for storage. If the original containers are not available, a separate cardboard container should be prepared that is large enough to accommodate sufficient packing material to prevent movement.

2.3 ANTENNA INSTALLATION

2.3.1 Location Considerations

Figure 2-1. Antenna Installation Considerations

A. The antenna (GARMIN P/N 010-10160-00) should be mounted away from major protrusions, such as

engine(s), propeller(s), and antenna masts. It should also be as far as practical from landing gear doors, access doors, or other openings that could effect its radiation pattern.

B. The antenna should be mounted on the underside of the aircraft and in a vertical position when the

aircraft is in level flight. The diversity antenna should be mounted on the top of the aircraft.

C. Avoid mounting the antenna within three feet of the ADF sense antenna or any other communication

antenna and six feet from the DME antenna.

D. To prevent RF interference, the antenna must be physically mounted a minimum distance of three feet

from the GTX 330.

GTX 330 Installation Manual Page 2-1 190-00207-02 Rev. 1

NOTE

If the antenna is being installed on a composite aircraft, ground planes must sometimes be added. Conductive wire mesh, radials, or thin aluminum sheets embedded in the composite material provide the proper ground plane allowing the antenna pattern (gain) to be maximized for optimum transponder performance.

2.3.2 Antenna Installation

Install the antenna according to the antenna manufacturer’s instructions and FAA AC 43.13-2A.

2.3.3 Installation Approval Considerations for Pressurized Aircraft

Antenna and cable installations on pressurized cabin aircraft require FAA approved installation design and engineering substantiation data whenever such installations incorporate alteration (penetration) of the cabin pressure vessel by connector holes and/or mounting arrangements.

For needed engineering support pertaining to the design and approval of such pressurized aircraft antenna installations, it is recommended that the installer proceed according to any of the following listed alternatives:

1. Obtain approved antenna installation design data from the aircraft manufacturer.

2. Obtain an FAA approved Supplemental Type Certificate (STC) pertaining to and valid for the subject

antenna installation.

3. Contact the FAA Aircraft Certification Office in the appropriate Region and request identification of FAA

Designated Engineering Representatives (DERs) who are authorized to prepare and approve the required antenna installation engineering data.

4. Obtain FAA Advisory Circular AC-183C and select (and contact) a DER from the roster of individuals

identified thereunder.

5. Contact an aviation industry organization such as the Aircraft Electronics Association and request their

assistance.

2.3.4 Antenna Cable Installation

When routing antenna cables, observe the following precautions:

• All cable routing should be kept as short as possible and as direct as possible.

• Avoid sharp bends.

• Avoid routing cables near power sources (e.g., 400 Hz generators, trim motors, etc.) or near power for

fluorescent lighting.

• Avoid routing cable near ADF antenna cable (allow at least a 12-inch separation).

The following table lists examples of the recommended antenna cable vendors and the type of cable to be used for specific lengths of cable. Any cable meeting specifications is acceptable for the installation. The maximum coaxial cable attenuation at 1090 MHz must not exceed 1.5 dB.

2.4 COOLING AIR

The GTX 330 meets all TSO requirements without forced air-cooling. (The application of forced air cooling to the rear air nozzle of the GTX 330 provides beneficial cooling to the unit. The GTX 330 is designed to dissipate its internal heat without the need of blowing air inside the unit.)

The GTX 330 was designed to handle a constant 450 PRF, with short periods of 1200 PRF. Rate limit is set at 1200 PRF. A typical radar site would interrogate the transponder once every 5 to 10 seconds for approximately 100 msec at a 400 PRF rate. In very high traffic areas with multiple ground stations and TCAS traffic it is possible to have long term PRF rates above 450 PRF. The GTX 330 measures the unit temperature and without forced air-cooling the reply rate will be reduced to protect the transmitter from overheating.

2.5 GTX 330 INSTALLATION

NOTE

Avoid installing the unit near heat sources. If this is not possible, insure that additional cooling is provided. Allow adequate space for installation of cables and connectors. The installer will supply and fabricate all of the cables. All wiring must be in accordance with FAA AC 43.13-2A.

Figure 2-2 Unit Installation Considerations

1. Assemble the connector/rack kit according to figure 4-2. Install the rack assembly according to the dimensions given in figures 4-1 and paragraph 1.4.2 Physical Characteristics of the GTX 330. Mounting brackets are not supplied due to the wide range of mounting configurations available. Suitable mounting brackets may be fabricated from sheet metal or angle stock. To insure a sturdy mount, rear support for the unit must be provided.

2. Looking at the bottom of the transponder, make sure the front lobe of the locking mechanism is in a vertical position. This can be accomplished by using a 3/32” Allen wrench through the face plate.

3. Slide the unit into the rack until the front lobe of the unit touches the rack.

4. Turn the Allen wrench clockwise until unit is secured in the rack. Continue turning until tight. Do not overtighten the screw.

5. To remove the unit from the rack, turn the 3/32” Allen wrench counterclockwise until it disengages from the rack.
