Hot section: FAA and EASA Approve King Air 350i Electrochromic Windows
Hawker Beechcraft has won STC approval from both the FAA and EASA for the Alteos interactive window system for its King Air 350i. The system, which is assembled and sold by PPG Industries through its Alteos brand, uses proprietary electrochromic technology from Gentex. It allows the user to lighten or darken the window by increasing or decreasing the electrical current passing through a gel layer between the layers of glass. According to Gentex senior v-p Enoch Jen, the King Air 350i is the first general and business aviation aircraft to use an electrochromic dimmable window system as standard equipment. The Alteos window system is not yet available as an aftermarket item for King Air 350is already in service but a spokesman for PPG said that is the intention.
