Garmin Clears Up the ADS-B Picture!

Garmin clears up the ADS-B picture!

Leave it to Garmin to clear up a very confusing, cluttered market of ADS-B products for general aviation.  This time there’s no rebranded products, partial approved model STC for certification, tricky install footnotes, gotchas or $7000 transponders.
The new GTX-335 and GTX-345 transponders are finally an all-in-one option that addresses almost every possible ADS-B installation scenario.
Features and options include:
  • Models available with or without internal WAAS GPS
  • ADS-B In capability (optional)
  • Most display compatibility option in the industry including G1000
  • Ideal size and fit factor (1.65” H) makes it easy to replace almost any panel mount transponder
  • Remote mount versions available for GTN 650/750 compatibility
  • Rack mount altitude encoder available to eliminate external wiring to encoder (optional – $299 List)
  • AML STC allowing for easy installation in hundreds of aircraft
  • List Prices start at $2995

Quite simply, if you already have a Garmin transponder (GTX-327/330 or remote GTX-32/33), then the GTX-335/345 are the most sensible option for you.  However, even if you have an older Mode C transponder, then the Garmin option is still the most sensible since you will update to a modern transponder while having complete ADS-B Out capability to comply with the 2020 mandate.

The ADS-B picture for general aviation is now much clearer.

Garmin Announces Next Generation All-in-One ADS-B Transponders

GTX345Garmin announced today the release of the GTX 345 and GTX 335, all-in-one ADS-B transponders, which include Extender Squitter (ES) ADS-B Out with options for built-in WAAS position source as well as dual-link ADS-B In. With the most compatibility options in the industry, these new transponders display on a wide variety of current and legacy Garmin displays, including select G1000 integrated flight decks. Regardless of the existing avionics configuration, the GTX 345 enables more capabilities for pilots by displaying ADS-B traffic, subscription-free weather, GPS position data and back-up attitude information within popular apps such as Garmin Pilot and ForeFlight Mobile via Connext wireless technology. The GTX 335/345 come in an attractive size and form factor, making it easy to replace the most popular transponders in the industry, like the Garmin GTX 327 and many others. Remote options are also available for compatibility with the GTN 650/750 series and G1000-equipped aircraft. List prices start at $2,995.

New Garmin Products, March 2013

Garmin LogoGarmin Intl. announced on March 13, 2014 the release of two new products, including a low-cost radar altimeter line and an angle of attack (AOA) system. Both of these products are expected to become available in the 2nd quarter of 2014. More information on these Garmin products will be provided when possible. Continue to follow SEA’s Blog and visit for the latest information on industry news and product releases.

Garmin Low-Cost Addition to Radar Altimeter Product Line

GRA 55
GRA 55

This comprehensive radar altimeter solution expands upon Garmin’s high-performance, all digital GRA 5500 radar altimeter to include the GRA 55, a best-in-class and cost-effective radar altimeter designed specifically for helicopters and general aviation aircraft. The GRA 55 leverages Garmin’s patent-pending digital signal processing technology that works to provide smooth altitude tracking and results in a consistent and highly accurate above ground level indication, even in the most challenging environments such as rough terrain, tree canopies, sand and choppy water. The solution also includes the new GI 205 stand-alone indicator, designed to pair with the GRA 55 or GRA 5500, which provides a comprehensive, stand-alone radar altimeter solution. These two new products meet the latest design standards and ultimately provide pilots with rock-solid confidence of their altitude above ground. In addition to helping owners and operators meet recent FAA requirements for radar altimeter equipage in commercial helicopter operations, the GRA 55 meets the most rigorous altitude accuracy requirements, only previously seen in products for transport and military aircraft. And together, the GRA 55 and GI 205 help fulfill recent FAA requirements for radar altimeter equipage in commercial helicopter operations.

The GRA 55 is expected to be available in the 2nd quarter of this year. The GRA 55 is compatible with select Garmin integrated flight decks and flights displays, as well as some compatible non-Garmin displays. The GI 205 is anticipated to be available in the 4th quarter of this year. A complete GRA 55 and GI 205 package, including antennas, will be available.

Garmin Safety Enhancing Angle of Attack (AOA) System

AOA System
AOA System

Garmin is announcing a new, intuitive, safety-enhancing, and simple to install angle of attack (AOA) system for general aviation aircraft. The system is comprised of the new GI 260 AOA indicator, GAP 26 angle of attack probe, and GSU 25 air data computer. The GI 260 is designed for quick, at-a-glance understanding of AOA during the most critical phases of flight and offers audible alerts in the event of a high-workload situation. This new system supports the FAA’s recent initiative to broaden adoption of Angle of Attack displays to improve safety.

The AOA System is expected to become available for installation in general aviation aircraft in the 3rd quarter of this year. Various packages are available that accommodate the appropriate aircraft voltage and include the option for a heated probe. Additionally, the GI 260 AOA indicator is available as an option for G3X and is expected to become available in the 2nd quarter.
