  • Remote-mounted Multichannel DME
  • Operates on 252 channels from 960 to 1215 MHz with both X and Y pulse-pair spacings with a transmitter output power of 300 watts minimum and a minimum receiver sensitivity of -85 dBm
  • Tracks three DME stations at once, providing accurate updates of aircraft position
  • Station identification recognition provides accurate updates of aircraft position
  • For enhanced safety, the Collins exclusive echo monitoring circuit prevents display of erroneous data from multipath reflected signals
  • ARINC 429 and CSDB tuning and data outputs provide a variety of installation options
  • Serial tuning and data output capabilities are compatible with the DME-442
  • Single set of high-speed ARINC 429 I/O buses provides tuning, digital audio, navigation data, maintenance data and software data loading capability
  • Interfaces with the RIU-4000 to allow a concentrated radio interface to the rest of the aircraft
  • Meets latest DO-160D Change 1 environmental requirements
  • Internal diagnostic capability minimizes time spent on fault diagnosis; fault code read out available on CTL or RTU
  • Comprehensive maintenance software package works with aircraft maintenance computer and service center test software for improved maintainability
