Honeywell Primus 660 and 880 naturally integrates with EFIS accompanied with one or two radar controllers, WC-880/884. With two controllers, Primus 660 and 880 can be operated like two separate radars. The pilot’s controller settings are used for one sweep, then the co-pilot’s are used for the subsequent sweep.
Also, the Primus 660 and 880 has its own independent weather radar indicator, the WI-880. The radar indicator has a special interface to connect the Lightning Sensor System or Data Nav V for added versatility in the cockpit.
