LUN1793 is determined for displaying telemetric data. It is intended for installation on the instrument panel by means of DZUS fasteners. Small size determines it for installation in constrained areas. LUN1793 receives information from other systems (for example GPS) via RS 422 and ARINC 429 interfaces. In current configuration, this information is displayed on three following screens.
