1 GENERAL DESCRIPTION

NOTE

1.1 Introduction

This manual is intended to provide mechanical and electrical information for use in the planning and design of an installation of the Garmin GTX 33 Mode S Transponder into an aircraft. These versions include all GTX 33, GTX 33D, GTX 33H, and GTX 33DH units with or without Extended Squitter Enabled; as part of a Garmin Integrated Flight Deck. This manual is not a substitute for an approved airframe-specific maintenance manual, installation design drawing, or complete installation data package. Attempting to install equipment by reference to this manual alone and without first planning or designing an installation specific to your aircraft may compromise your safety and is not recommended. The content of this manual assumes use by competent and qualified avionics engineering personnel and/or avionics installation specialists using standard aviation maintenance practices in accordance with Title 14 of the Code of Federal Regulations and other relevant accepted practices. This manual is not intended for use by individuals who do not possess the competencies and abilities set forth above.

Garmin recommends installation of the GTX 33 by a Garmin-authorized installer. To the extent allowable by law, Garmin will not be liable for damages resulting from improper or negligent installation of the GTX 33. For questions, please contact Garmin Aviation Product Support at 1-888-606-5482.

The GTX 33 can also be incorporated as a remote mounted unit in installations with other compatible control/display units such as the Garmin GNS 480 (CNX80), GTN 6XX/7XX, and GMX 200 (MX20) Multifunction Display (MFD).

1.2 Equipment Description

The Garmin GTX 33 rack mounted Mode S Transponder is a radio transmitter and receiver that operates on radar frequencies, receiving ground radar and TCAS interrogations at 1030 MHz and transmitting a coded response of pulses on a frequency of 1090 MHz. The GTX 33 is equipped with IDENT capability that activates the Special Position Identification (SPI) pulse for 18 seconds.

The GTX 33 replies to Mode A, Mode C and Mode S interrogation. Mode A replies consist of framing pulses and any one of 4,096 codes, which differ in the position and number of pulses transmitted. Mode C replies include framing pulses and encoded altitude.

The GTX 33 with Extended Squitter Enabled provides Automatic Dependent Surveillance-Broadcast (ADS-B) technology that 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 the transmission of interrogations for pertinent aircraft information at a slower update rate. ADS-B provides immediate surveillance of air-to-air traffic and aircraft in remote or inhospitable areas not currently covered by radar.

Ground stations can interrogate Mode S Transponders individually using a 24-bit ICAO Mode S address, which is unique to the particular aircraft. In addition, ground stations may interrogate a GTX 33 for its Transponder data capability and the aircraft's Flight ID, which is the registration number or other call sign. The GTX 33 makes the maximum airspeed capability (set during configuration setup) available to TCAS systems on-board nearby aircraft to aid in the determination of TCAS advisories.

The unit features an altitude monitor and TIS traffic advisories. A voice or tone audio output announces altitude and traffic alerts. The GDU Primary Flight Display screen displays the code, reply symbol and mode of operation, depending on equipment connections and configuration selection. The GNS 480

190-00906-00 GTX 33 Installation Manual Rev. H Page 1-1

(CNX80), GTN 6XX/7XX, and GMX 200 (MX20) MFD provide similar information with the addition of

NOTE

pressure altitude.

The GTX 33 features multiple transmit/receive ARINC 429 and RS-232 data ports. The unit concentrates data from three ARINC 429 inputs, gray code, RS-232 input data and discrete inputs to the high-speed RS-232 data ports for display on the flight displays. Although multiple output capability is available, the unit is designed to feed all outgoing data via RS-232 data ports. Two RS-232 data ports send and receive data to/from the GIA 63(W) Integrated Avionics Units (IAU), GNS 480 (CNX80), GTN 6XX/7XX, or GMX 200 (MX20) Multifunction Display.

Provision is made for unit software upgrade by means of RS-232 data through rear connector pins. In installations where the transponder interfaces with a GNS 480 (CNX80) or GTN 6XX/7XX the installation of an optional connector is highly recommended. If the optional connector is placed in the aircraft, transponder removal and reinstallation for software upgrade is not required. The software can be changed while the unit is still mounted inside the aircraft.

The GTX 33 meets Mode S Enhanced Surveillance (EHS) requirements. Mode S Enhanced Surveillance is used predominantly in European airspace. It provides information consisting of additional aircraft parameters (see JAA NPA 20-12a) to ground radar systems. Compliance with Enhanced Surveillance may require additional interface between aircraft systems and the GTX 33.

The GTX 33 and GTX 33D differ from the GTX 33H and GTX 33DH in the qualified DO-160 vibration categories. See the GTX 33 Environmental Qualification Form (005-00131-03) for details.

1.3 ADS-B Capabilities

The Extended Squitter Enabled GTX 33 provides the capabilities of Automatic Dependent SurveillanceBroadcast (ADS-B) technology, which 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. ADS-B provides automatic transmission of aircraft information without a request.

RS-232 ADS-B Out from a Garmin 4XX/5XX WAAS, GTN 6XX/7XX with GPS software version 3.20 or later, or a GPS WAAS source that supports ARINC 743A output is required to support ADS-B transmissions.

GTX 33 Installation Manual 190-00906-00 Page 1-2 Rev. H

1.3.1 ADS-B Versions

NOTE

There are three distinct ADS-B versions recognized by regulatory authorities. As show in the table below, the Garmin GTX 33 w/ES currently supports ADS-B Out 1090MHz Extended Squitter capability meeting ‘Version 1’ ADS-B or ‘Version 2' ADS-B system requirements depending on software version (see Table 1-1).

GTX 33 w/ES transponders with software version 6.20 or earlier are not compliant with ADS-B version required by the 14 CFR 91.225(a) equipage mandate.

1.3.1.1 Installation Approval of Version 1 ADS-B Systems

GTX 33 w/ES transponders running software versions v6.00 through v6.20 support Version 1 ADS-B Out functionality. According to AIR-130 Policy Memo ‘Approval for ADS-B Out Systems’, dated August 30, 2010, the FAA has suspended field approvals of Version 2

ADS-B Out equipment. At the time of this publication, there is currently no FAA policy addressing field approvals of Version 0 or Version 1 systems. GTX 33 w/ES transponders with Version 1 ADS-B remain eligible for field approval.

There are three options for installers wanting to install GTX 33 w/ES transponders with software versions

6.00 through 6.20:

1. Installers may elect to disable the ADS-B Extended Squitter function, as described in Section

3.7.1.

2. Installers may utilize a Supplemental Type Certificate (STC) for the GTX 33 with the Version 1 ADS-B Extended Squitter activated.

3. Installers may obtain a field approval with the Version 1 ADS-B Extended Squitter activated. EASA AMC 20-24 compliance matrix provided in Appendix B may be used to assist installers in showing compliance to the AMC requirements. This data together with Form 337 may be used for approval by the appropriate FSDO inspector.

190-00906-00 GTX 33 Installation Manual Rev. H Page 1-3

1.3.1.2 Installation Approval of Version 2 ADS-B Systems

NOTE

GTX 33 w/ES transponders running software versions v7.01 and later support Version 2 ADS-B Out functionality. According to AIR-130 Policy Memo ‘Approval for ADS-B Out Systems’, dated August 30, 2010, a Supplemental Type Certificate (STC) is required for the approval of Version 2 ADS-B Out equipment.

There are two options for installers wanting to install GTX 33 w/ES transponders running software versions v7.01 and later:

1. Installers may elect to disable the ADS-B Extended Squitter function, as described in Section

3.7.1.

2. Installers must utilize a Supplemental Type Certificate (STC) for the GTX 33 with the Version 2 ADS-B Extended Squitter activated.

It is the installer’s responsibility to ensure the ADS-B Out system is compliant with AC 20-165 and to ensure compatibility between the GTX 33 and the ADS-B Out position source equipment. See Garmin ADS-B Out Compatible Equipment (190-01533-00) for compatible equipment shown to be eligible for 14 CFR 91.227-compliant installations in accordance with AC 20-165

1.4 TIS System Capabilities

Traffic Information Service (TIS) provides a graphic display of traffic advisory information in the cockpit for non-TCAS equipped aircraft.

TIS is a ground-based service providing relative location of all transponder equipped aircraft within a specified service volume. The TIS ground sensor uses real time track reports to generate traffic notification.

Traffic display is available to aircraft equipped with a Mode S data link such as the Garmin GTX 33 transponder. Traffic can then be displayed on a Garmin GDU Primary Flight Display, GMX 200 (MX20) Multifunction Display, GNS 480 (CNX80), GTN 6XX/7XX or other compatible display unit.

Surveillance data includes all transponder equipped aircraft within the coverage volume. Aircraft without an operating transponder are invisible to TIS. TIS displays traffic within seven nautical miles from 3000 feet below to 3500 feet above the requesting aircraft.

1.5 Mutual Suppression Pulses

Other equipment on board the aircraft may transmit in the same frequency band as the transponder, such as DME or another transponder. Mutual suppression is a synchronous pulse that is sent to the other equipment to suppress transmission of a competing transmitter for the duration of the pulse train transmission. The transponder transmission is suppressed by an external source and other equipment on board is suppressed by the GTX 33 transponder. This feature is designed to limit mutual interference.

1.8 Aircraft Station Licensing Requirements

CAUTION

NOTE

The Telecommunications Act of 1996, effective February 8, 1996, provides the FCC discretion to eliminate radio station license requirements for aircraft and ships. The GTX 33 installation must comply with current transmitter licensing requirements. To find out the specific details on whether a particular installation is exempt from licensing, please visit the FCC web site http://wireless.fcc.gov/aviation

If an aircraft license is required, make application for a license on FCC form 404, Application for Aircraft Radio Station License. The FCC also has a fax-on-demand service to provide forms by fax. The GTX 33 owner accepts all responsibility for obtaining the proper licensing before using the GTX 33.

The UHF transmitter in this equipment is guaranteed to meet federal communications commission acceptance over the operating temperature range. Modifications not expressly approved by Garmin could invalidate the license and make it unlawful to operate the equipment.

For non-US installations consult the local spectrum management agency for requirements.
