Product description

The RDU-4047’s 4"x7" (8") proprietary Active Matrix Liquid Crystal Display and LED backlight technology deliver a visual performance second to none: high color depth, contrast ratio and superior color stability, very wide viewing angles and superior brightness modes. This allows the display to be mounted in portrait or landscape both vertically in front of the pilots and tilted horizontally in the pedestal, assuring perfect cross-cockpit vision.

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.

Its multiple digital video and control interfaces allow for an easy integration with several sources. And last but not least, the optional touchscreen enables the integration of various cockpit functions reducing overall cockpit system costs and space requirements.  Therefore this display is ideal in Control Display, HUD repeater, ... applications.

The software and firmware of the RDU-4047 are developed according to DO-178 and DO-254 respectively, up to and including Design Assurance Level (DAL) A.
