ADS-B Packages Under Way for Honeywell Primus Flight Decks

Duncan Aviation and Honeywell are developing ADS-B out upgrades for 800-series Hawkers and Citation 560s equipped with the Primus 1000/2000 and SPZ-8000 or Primus II avionics, respectively. The upgrade will meet the latest DO-260B standards required for U.S. and European ADS-B out compliance, and it meets standards in other parts of the world as well. As part of the upgrade, owners and operators will be able to replace CRT-based RM 850 radio tuning units with the new and more reliable RM855, which has an LCD. According to Honeywell, it stopped making the RM 850 in 2006 and has not repaired any since 2010.
