The Litton Guidance and Control Systems Division in Woodland Hills, Calif., will retrofit Bell UH-60A helicopters of the Tennessee National Guard with new smart multi-function liquid crystal displays. Litton is working under contract with United Technologies Sikorsky Aircraft Division in Stratford, Conn. The initial contract calls for Litton engineers to provide two displays on each of four aircraft, with a potential of 87 aircraft to be upgraded, which will be called the UH-60Q. Litton`s 6-by-8-inch displays operate in color or green monochrome. They replace the existing aircraft`s caution advisory panels and deliver high-resolution forward-looking infrared sensor imaging. They also display backup navigation, location, attitude, and radio communications symbology. Providing the LCD technology, which is readable in direct sunlight or through night-vision goggles, is Litton Systems Canada Ltd. in Etobicoke, Ontario. - J.K.
