In a first for an avionics installer, Duncan Aviation has certified and installed the Universal Avionics EFI-890R retrofit cockpit system in a customer Challenger 600. Part of Duncan’s Glass Box Project–which seeks to pair appropriate avionics upgrade hardware with various business airplanes–the Challenger cockpit features four 8- by 9-inch LCD flight displays and a 4- by 6-inch MFD-640 multifunction display. This summer Duncan plans to add Universal’s Vision 1 synthetic-vision capability to the STC, as well as WSI datalink weather.
