Item 7.01 Regulation FD Disclosure

Woodbury, NY, May 20, 2015 – Electronically Dimmable Windows (EDWs) using patented SPD-Smart light-control technology invented by Research Frontiers, and supplied by InspecTech Aero Service, have been selected as standard equipment on the King Air C90GTx, the King Air 250, and the King Air 350i. Visitors to the European Business Aviation Convention and Exhibition (EBACE) in Geneva this week can experience these state-of-the art EDWs on the King Air 250 being exhibited there by Beechcraft.

SPD-Smart EDW systems use Research Frontiers patented SPD-Smart light-control film technology as the foundation that delivers unprecedented benefits to all aircraft passengers. At the touch of a button, passengers can instantly and precisely control the amount of daylight and glare coming through their window. They continue to enjoy views while maintaining a comfortable level of daylight, by tinting their SPD-Smart EDW to any desired level. SPD-Smart EDWs also feature thermal and acoustic insulation, further improving the passenger experience by contributing to a cooler, quieter cabin.
