Sandel Adds LED to SN3500

Sandel last month said it has started shipping an upgraded version of its SN3500 EHSI (electronic horizontal situation indicator) that features LED (light-emitting diode) backlighting similar to the technology introduced last year in its larger displays. Providing a brighter and sharper display image, the technology replaces Sandel’s previous backlighting technique with a long-life glass panel rated at 10,000 hours MTBF. Benefits include better sunlight readability, improved resolution and reduced maintenance costs, according to Sandel. The company introduced LED backlighting in its 4-ATI primary flight and nav displays last year.
