With its all-digital design, the GRA 5500 represents the latest and most accurate technology available in radar altimeters. It’s reliableenough to meet the needs of even the most demanding helicopter, business jet, transport category and general aviation applications whilebeing so accurate it can serve as an integral part of your Class A TAWS, TCAS II or CAT II ILS solution.
Discover the All-Digital Advantage
The GRA 5500’s patent-pending digital signal processing technology can intelligently processhundreds of altitude readings every second and filter out anomalies, smooth altitude tracking and crosscheck data and system integrity.These benefits combine to provide a smooth and consistent readout of your altitude Above Ground Level (AGL). The GRA 5500 is designed towork in a multitude of environments, allowing you to go from rough terrain to tree canopies, sand to choppy water and know exactly how muchroom you have to maneuver. Gain added peace of mind knowing that the radar altimeter is operating normally thanks to patent-pendingself-testing technology that continuously monitors incoming data and system integrity to help assure that the altitude provided is accurate,even in low-visibility conditions. In most installations, this self-testing technology eliminates the need for the pilot to interact withthe GRA 5500 in any way.
Interface With Your Avionics
Designed to work with Garmin flight displays like the G500, G500H and G600, the GRA 5500 convenientlyputs your AGL readout right in front of you. This display integration, along with its reliability and accuracy, make it an optimal solutionfor operators equipping for NVIS operations. The GRA 5500 also integrates with the GTS 8000 and GTX 3000 to provide a complete TCAS IIsystem, and satisfies radar altimeter requirements for Class A TAWS systems and CAT II ILS operations. In fact, in many installations only asingle GRA 5500 may be required where multiple redundant analog radar altimeters might otherwise be needed. The GRA 5500 offers a simplerinstallation that can further provide you with weight and cost savings by eliminating the need for long lengths of antenna cabling that aretraditionally required in the installation of radar altimeters.
