Duncan Aviation has ADS-B Out Solution for Citation 560/560XL/Ultra & Encore Aircraft

Duncan Aviation recently completed Supplemental Type Certification for installation of an ADS-B Out solution for Citation 560 / 560XL / Ultra and Encore aircraft equipped with Honeywell’s Primus radio system.

“Many Citation operators are interested in meeting the ADS-B mandate but keeping their aircraft in an industry-standard configuration, “ says Gary Harpster, a longtime avionics representative with Duncan Aviation. “That’s why we worked with Honeywell to develop this solution, which allows operators the ability to meet the 2020 mandate deadline with time to spare.”  

ADS-B Out allows an aircraft to transmit information to ATC ground stations and to properly equipped aircraft. Position data will be automatically broadcast from all ADS-B Out-equipped aircraft. ATC ground stations and ADS-B In-equipped aircraft will receive this data. ADS-B Out has been mandated by the FAA in the airspace that now requires a Mode-C transponder.

Duncan Aviation STC # ST01810WI utilizes the an integrated solution with Honeywell equipment by upgrading  existing Honeywell Primus radios and adding a standalone GPS receiver.

“This provides the most cost-effective solution for the aircraft while maintaining industry make and model standards,” Harpster says.
