2 SYSTEM DESCRIPTION

2.1 Equipment Descriptions

2.1.1GTN 6XX/7XX Navigators and GMA 35

The GTN SBAS navigators are a family of aviation panel mounted retro-fit products. The following sections will describe the available functions for each unit in the GTN 6XX/7XX navigators.

2.1.1.1GTN 6XX

The GTN 6XX SBAS navigators are a family of panel-mounted GPS/NAV/COM navigators.

The GTN 6XX units include the GTN 625, GTN 635, and GTN 650. They are 6.25" wide and 2.65" tall. The GTN 6XX features a 600 by 266 pixel color LCD touchscreen. The GTN 625 is a GPS/SBAS unit that meets the requirements of Technical Standard Order TSO-C146c and may be approved for IFR en route, terminal, oceanic, non-precision, and precision approach operations when installed in accordance with the instructions in the manuals referenced in the GTN AML STC. The

GTN 635 includes all of the features of the GTN 625 in addition to an airborne VHF communications transceiver. The GTN 650 includes all of the features of the GTN 625 in addition to an airborne VHF communications transceiver and airborne VOR/localizer (LOC) and glideslope (G/S) receivers.

2.1.1.2GTN 7XX

The GTN 7XX SBAS navigators are a family of GPS/NAV/COM aviation panel-mounted products. The GTN 7XX units include the GTN 725 and GTN 750. The GTN 7XX units are 6.25" wide and 6.00" tall. They feature a 600 by 708 pixel color LCD touchscreen. The GTN 725 is a GPS/SBAS unit that meets the requirements of Technical Standard Order TSO-C146c and may be approved for IFR en route, terminal, oceanic, non-precision, and precision approach operations when installed in accordance with the instructions in the manuals referenced in the GTN AML STC. The GTN 750 includes all of the features of the GTN 725 in addition to an airborne VHF communications transceiver and airborne VOR/localizer (LOC) and glideslope (G/S) receivers. The GTN 725 and 750 also have the ability to remotely control GMA 35 audio panel functions.

2.1.1.3GMA 35 Audio Panel

The GMA 35 audio panel is both a marker beacon receiver and an audio panel with 6-place intercom that interfaces to the communications and navigation radios, headsets, microphones, and speakers. The GMA 35 is remote-mounted and relies upon the GTN 725 or GTN 750 to control and display the audio functions.

The GMA 35 interfaces to the GTN 7XX through RS-232 for control and display of audio panel functions. Additionally, the GMA 35 includes a six-position intercom system (ICS) with electronic cabin noise deemphasis, two stereo music inputs, and independent pilot, copilot, and passenger volume controls. The intercom provides three selectable isolation modes. A pilot-selectable cabin speaker output can be used to listen to the selected aircraft radios or to broadcast PA announcements.

2.1.1.4Flight Stream 210

The Flight Stream 210 brings Bluetooth® connectivity to the cockpit, allowing portable electronics to stream data to and from the installed avionics.

The Flight Stream 210 interfaces to the GTN 6XX/7XX (Flight Stream supports connection to one navigator at a time) through RS-232 for attitude information, flight plan information, and GPS PVT and displays that information on a portable electronic device (PED). The Flight Stream may interface to the GDL 88 through RS-422 and the GDL 69 through RS-232 as well.

Rev. 7	Page 2-1

2.1.2NAV Antenna Cable Splitter

The navigation antenna cable splitter (Garmin P/N 013-00112-00) is used for installations involving dual VHF navigation capable GTNs or a single VHF navigation capable GTN installation with a second non-Garmin aviation unit.

2.1.3NAV Antenna Cable Diplexer

The GTN 650/750 navigation units have a single navigation antenna port and thus require a composite signal for those installations which include separate VOR/LOC and G/S antennas. The navigation diplexer (Comant diplexer VOR/GS, Model CI-507) is used for these installations.

3.3 Software Loading

3.3.1GTN Software Loader Card Creation

A GTN Software Loader Card may be created using GTN Downloadable Software and an SD card in conjunction with a GTN software application downloaded from the Dealer Resource Center on Garmin’s website. The Dealer Resource Center will allow the technician to choose which software package(s) to load onto the card.

NOTE

The downloadable application to create the GTN Software Loader Card only runs on PCs with Windows. Windows 2000, XP, Vista, and Windows 7 are supported. There is no Macintosh support at this time.

NOTE

An SD card reader is needed to create the GTN Software Loader card using the application that is downloaded from Garmin. The approved readers are SanDisk® SDDR-999 and SDDR-93, although other SD card readers will work.

Create a GTN Software Loader Card as follows:

1.Go to the Dealer Resource Center on Garmin’s website.

2.Download the GTN Software Loader Image. Refer to the Equipment List (P/N 005-00533-C1) for the correct Software Loader Image part number.

3.Ensure that you have an SD card reader connected to the PC. Insert the GTN Downloadable Software SD Card into the card reader.

4.Run the executable file. The screen shown in Figure 3-3 will appear.

Figure 3-3. GTN Software Updater

5.Click Setup. The window shown in Figure 3-4 will appear to guide you through the software loader card creation process.

2.Insert the GTN Software Loader Card into the GTN 7XX data card slot (See Section 3.3.1 for instructions on how to create a GTN Software Loader Card).

3.Hold down the HOME key until Garmin is fully lit on the display after power is applied by closing the circuit breaker for the GTN 7XX.

4.Ensure the GMA 35 circuit breaker is also closed.

5.The Configuration Mode page should now be displayed. Touch the Updates key to display the software that is available.

6.To select GMA 35 software updates, touch the GTN Software Updates key on the top left corner of the display and select GMA 35 Software Updates.

7.To update the GMA 35 with all software available, touch Select All.

8.To begin the software update, touch the Update key on the bottom of the display.

9.The GTN will display the prompt, ‘Start GMA 35 Software Updates?’

10.Touch OK to allow the GTN to update the GMA 35.

11.When the updates are finished, the GTN will display ‘Update Complete!’

12.When finished, turn the GTN and GMA 35 off (open the circuit breaker) and remove the Software Loader Card. Reinsert the database card in the data card slot.

13.Restore power on the GTN and GMA 35 by closing the circuit breakers and ensure the software was updated correctly by going to the System Information page and selecting the GMA 35. Refer to Section 3.4.2 for more information on the System Information page.
