Garmin® Announces Enhancements for 400/500 Avionics

GTX™ 330

OLATHE, Kan. — Garmin International Inc., a unit of Garmin Ltd. (Nasdaq: GRMN), today unveiled the company’s plans to upgrade its 400 and 500 avionics series, including the feature-rich, integrated GNS 430 and GNS 530. These upgrades refer to specific avionics units [see below] and include terrain advisories, certified Terrain Avoidance and Warning System (TAWS) and precision landings via the Wide Area Augmentation System (WAAS). The company plans to start implementing its internal terrain and TAWS upgrades later this year.

" It has always been a goal of ours to add terrain, TAWS-B and WAAS to our popular line of panel-mount avionics, and we’re excited to deliver these internal upgrades to our popular 400 and 500 series," said Gary Kelley, Garmin's director of marketing. "Pilots can expect true-to-form Garmin innovation in the way that our MFD-like GNS 430 and GNS 530 will display critical information about the terrain below and ahead of them, improving overall flight safety."

Upgrade Paths
Garmin is committed to continuously improving its avionics as a service to current and future 400/500 series owners. As Garmin maps out further enhancements to its avionics product line, the company plans to offer the following upgrades to owners of its GPS 400, GNC® 420, GNS 430, GPS 500 and GNS 530 avionics units. These upgrades follow respective timelines:

  • Garmin will offer terrain advisories as an internal upgrade on its 400/500 avionics in the fourth quarter of 2003. This upgrade will cost $500 and will enable the 400/500 series to identify potential hazards, displaying them in yellow and red, so the pilot can avoid possible CFIT accidents.

  • Additionally, current Garmin 500 series owners can opt for a Class-B TAWS upgrade starting in the fourth quarter of 2003. This upgrade will cost $6,495 for orders placed through the end of the year. TAWS upgrades must be completed at Garmin's factory overhaul facilities in Olathe, Kan., and Romsey, U.K. This upgrade meets an important FAA mandate requiring TAWS-B for turbine-powered aircraft with six or more passenger seats.
  • Garmin is committed to offering WAAS upgrades for the 400/500 series and plans to provide the benefits of WAAS on these products for less than $1,500 by the end of 2004. This upgrade must also be completed at Garmin's overhaul facilities in the U.S. and U.K.

Garmin: General Aviation's Stack of Choice
Garmin GPS-enabled avionics have been installed on nearly three-fourths of all U.S. single- and twin-engine piston and turbine aircraft retrofitted since 2000. The company’s panel-mount avionics have also gained significant market share among factory-installed equipment on general aviation aircraft during that same time period. The typical Garmin avionics stack includes the GNS 430/530, GTX™ 330 and GMA 340.

At the heart of the industry’s leading avionics suite are the Garmin GNS 430 and GNS 530. The GNS 430/530 integrates IFR GPS; VHF navigation with VOR, instrument landing system (ILS) with glideslope; and VHF communication in either 10- or 16-watt configuration with 8.33-kHz channel spacing — and presents this information on a four-inch and five-inch (diagonal) color, moving-map display, respectively. Both units display critical Jeppesen® data, which is overlaid on a detailed basemap of cities, highways, rivers, lakes and geopolitical borders. The GNS 430/530 also provides interface capabilities for weather data link via the Garmin GDL 49, lightning detection and traffic. The GNS 430 and GNS 530 are compatible with aircraft with 14- or 28-volt electrical systems and carry list prices of $9,250 and $14,995 for 10-watt COM units, respectively, and $14,250 and $19,995 for 16-watt COM units, respectively.

The GTX 330 is a solid-state, digital Mode S transponder with an interface for traffic awareness via the FAA’s Traffic Information Service (TIS). Garmin was the first manufacturer to certify a TIS-enabled Mode S transponder, giving pilots the ability to receive traffic updates within 60 miles of nearly 120 participating airports in the U.S. The data is transferred to the display of the GNS 430/530, including flight-path vectors — allowing the pilot to see what the ATC sees. Like all solid-state Garmin transponders, the GTX 330 uses less power, reduces heat emissions and requires no warm-up time. Its yellow-on-black digital display allows for easy viewing and operation when entering squawk codes and flight IDs. Further, the GTX 330 can display outside air temperature, altitude and density altitude. It also features a voice annunciator, which alerts the pilot when pre-set altitude limits have been exceeded. Garmin also offers the GTX 330D, which takes all of the features of the GTX 330 and adds another receiver and antenna for improved visibility to TCAS-equipped aircraft flying overhead. The GTX 330 and GTX 330D have list prices of $4,995 and $9,995, respectively.

The GMA 340 Audio Panel rounds out the Garmin avionics suite. The GMS 340 is designed to offer pilots reliable and versatile audio-switching functions in a user-friendly front panel layout. Among other things, the GMA 340 offers a six-position stereo intercom, three COM positions with split COM, marker beacon with audio-muting, TX indication, and a speaker output for radios and PA function. The GMA 340 has a list price of $1,650.
