Garmin expands radar altimeter line

Garmin has unveiled a radar altimeter solution that expands upon Garmin’s all digital GRA 5500 radar altimeter to include the GRA 55, a 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 above ground level indication, even in the most challenging environments such as rough terrain, tree canopies, sand and choppy water, according to Garmin officials.

The new GI 205 stand-alone indicator, designed to pair with the GRA 55 or GRA 5500, provides a stand-alone radar altimeter solution for owners seeking a cost-effective display, officials add.

GarminGI205Patent-pending technology in the GRA 55 incorporates built-in self-test monitors that continuously cross check system and data integrity, assuring the pilot of an accurate measurement of the height above ground, company officials explained. This technology also provides for a simpler installation with easy calibration and eliminates the requirement for long lengths of antenna cables that are traditionally required in the installation of radar altimeters, officials add.

The GI 205 stand-alone indicator (pictured) features a display with 180° viewing angle, allowing radar altimeter indications to be seen  in all types of flight conditions, day or night.

Visual and audible alerts are available to ensure all altitude indications are clearly presented in-flight. Pilot-selectable decision height (DH) is easy to adjust using a knob and upon arrival at the DH, a “minimums, minimums” voice callout or traditional audible tone is available.

Adding to situational awareness, an intuitive graphical trend indicator displays vertical velocity information, such that altitude trend can be monitored at a glance and corrections can be made promptly to avoid inadvertent climbs or descents, Garmin officials said.

The GRA 55 is expected to be available in the second quarter of this year for a list price of $6,995 and is compatible with select Garmin integrated flight decks and flight displays, as well as some third-party displays.

The GI 205 is anticipated to be available in the fourth quarter of this year for a list price of $3,995.

A complete GRA 55 and GI 205 package (including antennas) will be available for an introductory list price of $11,995.
