Duncan Aviation STCs ADS-B for Hawker 800/Hawker 800XP
The company is installing new RM-855s in place of the aircraft's legacy RM-850.

Duncan Aviation recently completed a supplemental type certificate (STC) to upgrade existing Honeywell Primus avionics in the Hawker 800/800XP so they are ADS-B OUT compliant.
