Duncan Aviation has installed and certified the Universal Avionics EFI-890R retrofit avionics system in a King Air 300, the Battle Creek, Mich. company reported. The STC for the package covers two- and three-display systems, with Universal’s large-format 8.9-inch active matrix LCD screens serving as the centerpiece for the upgrade. This particular installation, completed last month, included three displays.
Stevens Aviation, meanwhile, has started work on a similar King Air 300 installation at the company’s maintenance center in Nashville. The system will include a UNS-1L flight management system, terrain awareness and warning system and provisions for a Vision-1 synthetic-vision display.
