Základní informace

  • Best-in-class true 8-bit AMLCD for superior color rendering
  • Brightness >300fL, making it suitable for installation in helicopters and open cockpit aircraft
  • NVIS Class B compatibility
  • Guaranteed brightness and color range over the operating temperature of the display and over its lifetime
  • Multiple video inputs
  • 5.75" DZUS rack mountable
  • Quiet by design, thanks to its closed and fan-less architecture

The RDU-4138’s proprietary Active Matrix Liquid Crystal Display and LED backlight technology deliver a visual performance second to none: true 8-bit color depth with high contrast ratio and superior color stability, very wide viewing angles and superior brightness in Day, Night and NVIS modes. And there is even more: the optical quality is guaranteed over the complete operating temperature range and lifetime of the display, thanks to ScioTeq ’s proprietary control mechanisms. As an option, the light can be collimated to reduce reflections on the windshield or canopy. 

The software and firmware of the RDU-4138 are developed according to DO-178C and DO-254 respectively, up to and including Design Assurance Level (DAL) A. This display is therefore an ideal candidate for Part 23, Part 25, Part 27 and Part 29 electronic flight instrument systems.
