Garmin GRA 5500 - Unit Condition: New

Features

• High-performance all digital radar altimeter
• Used on transport category, helicopter, business and general aviation aircraft
• Patent pending digital signal processing technology
• Provides smooth altitude tracking resulting in consistent and highly accurate altitude above ground indication, even over environments like rough terrain, tree canopies, sand and choppy water
• Works up to 2,500 ft above ground level
• 1.5 foot accuracy
• Simplified installation procedure
• Eliminates the requirement for long lengths of antenna cables traditionally required in the installation of radar altimeters
• Built-in self-test monitors continuously cross check data and system integrity, assuring the pilot of an accurate measurement of the height above ground
• Able to integrate with existing systems to enhance NVIS operations and fulfill the radar altimeter requirements for Class A TAWS, CAT II ILS operations and TCAS II/ACAS II
• Compatible with Garmin's new TCAS II/ACAS II
• Has been selected as standard equipment on new aircraft including Cessna Citation X, Citation Sovereign, Citation Latitude, Citation Longitude, and the Bell Helicopter 525 Relentless
• Has received the FAA's Technical Standard Order (TSO) authorization
