Rockwell Collins has expanded its Pro Line Fusion avionics upgrade to include Pro Line II-equipped King Air 350s. The retrofit delivers a NextGen-capable avionics system with three interchangeable 14-inch touchscreen flight displays, the company said. Capabilities include synthetic vision; geo-referenced e-charts with own-ship position display; touch-interactive graphical maps; and localizer performance with vertical navigation approach capability. Rockwell Collins is collaborating with Landmark Aviation to STC the upgrade in the first half of next year. The upgrade has an estimated flyaway price that is “substantially more affordable than the current certified glass cockpit retrofit on the market,” said the company.
