King Air 350i Gets Electric Shades

PPG Industries’ aerospace transparencies business and Gentex will be providing electrochromic window systems to Hawker Beechcraft as standard equipment for the manufacturer’s 2010 King Air 350i cabin windows. The PPG-Gentex system–dubbed Alteos–replaces the mechanical shade system, allowing passengers to control the visible-light transmittance of a dimmable panel between the inboard dust cover and outboard, structural cabin window. The dimmable-window panel works by introduction of a mild electrical current. Depending on the strength of the current, the window changes “from a bright, clear state to nearly opaque, or to a comfortable intermediate setting,” according to PPG.
