Description
The SI 205 is a Radar Altimeter control head designed to operate with the Garmin GRA 55/5500 radar altimeter systems. It is a direct replacement for the GI205. The stand-alone SI 205 represents the best-in-class technology available for stand-alone radar altimeters displays. It’s built to meet the needs of even the most demanding helicopter and general aviation applications. Together, the GRA 55 and GI 205 can comprise a complete radar altimeter solution. The total system’s reliability and accuracy, along with its flexible display capabilities, make it an optimal solution for operators equipping for NVIS operations or Part 135 operators looking to meet FAA requirements.
