Learn How Gentex Dimmable Windows Cut Glare Without Taking Away the View | Aviation Week

Gentex dimmable windows (EDWs) are designed to cut glare while keeping passengers able to see through the glass. In Aviation Week’s Q&A, Gentex explains that crews can connect the windows to the flight attendant panel to adjust cabin lighting by zone, including settings meant to create mood lighting. Passengers can also dim their own windows within set limits, without flight attendants reaching over sleeping passengers to move shades. Technically, the windows are electrochromic: powered, they darken by absorbing visible light; power off returns them to transparent. Gentex says they have no moving parts, are insulated, and show eight to 10 times better reliability than standard pull-down shades, with fail-safe default clear required for certification.
