Israel’s Elbit Systems announced that subsidiary Kollsman has acquired a 20-percent stake in Sandel Avionics of Vista, Calif. Valued at $12 million, the deal forms a marketing and engineering alliance between the companies and includes an option for Kollsman to buy the remaining 80 percent of Sandel within 30 months. Based in Merrimack, N.H., Kollsman produces the EVS for large Gulfstreams and is developing a lighter, less expensive uncooled system for smaller aircraft. Sandel sells cockpit moving maps and TAWS designed to occupy minimal space in the panel.
