New Low-Cost Addition to Radar Altimeter Product Line
Patent-pending technology in the GRA 55 incorporates built-in self-test monitors that continuously cross check the data and system integrity, assuring the pilot of an accurate measurement of the height above ground, even over challenging ground conditions. This technology also provides for a simpler installation, with easy calibration, and eliminates the requirement for long antenna cables that are traditionally required for the installation of radar altimeters.
The GI 205 stand-alone indicator features a vibrant OLED display with full 180-degree viewing angle, allowing radar altimeter indications to be seen easily 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 select 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, so that altitude trend can be monitored at a glance and corrections can be made promptly to avoid inadvertent climbs or descents.
For Part 135 helicopter operators, the GRA 55 fulfills the radar altimeter equipage requirement recently established by the FAA, and the GRA 55 paired with the GI 205 provides the best-in-class solution to meet these new requirements. Coupled with the GI 205 stand-alone indicator, operators can incorporate a complete, costeffective radar altimeter solution into their flight decks without the need to purchase an entire flight display system.
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 also be available.
