Three STCs Developed for Embraer Legacy


Duncan Aviation recently completed an industry first installation of the Honeywell Primus Elite (DU-875 displays) in an Embraer Legacy. The DU-875 upgraded electronic displays in the cockpit because the old screens had been discontinued, and the new screens provide additional charts and graphical weather information. Duncan Aviation and Honeywell Aerospace also completed two other STCs for the Embraer Legacy, covering the installation of the following:

Upgrade of the Honeywell FMZ-2000 FMS to FMZ-2010 for LPV/WAAS (Localizer Performance with Vertical Guidance/Wide Area Augmentation System) capabilities.

The Honeywell CMU MKIII, which brought the aircraft into compliance for Future Air Navigation Systems (FANS 1/A+). FANS is mandatory for flying in the NAT (North Atlantic Tracks).

One of Duncan Aviation’s existing STCs was also used to install the Honeywell MK V EGPWS (Enhanced Ground Proximity Warning System) RAAS (Runway Awareness and Advisory System) and Smart Runway/Smart Landing equipment. And an STC developed by CMD Flight Solutions was used to install the Honeywell Primus II RCZ-8XX transponders, bringing the Legacy into compliance with the FAA’s mandate for ADS-B Out a full two years before the midnight deadline on December 31, 2019.
