PRIMUSr 880 Digital Weather Radar System

The radar indicator is equipped with the universal digital interface (UDI). This feature expands the use of the radar indicator to display information such as checklists, short and long range navigation displays (when used with a Honeywell DATA NAV system) and electrical discharge data from Honeywell’s LSZ- 850 Lightning Sensor System (LSS).

NOTE: Refer to Honeywell Pub. 28- 1146- 54, LSZ- 850 Lightning Sensor System Pilot’s Handbook, for more information.
