Alteos® Interactive Window Systems

Alteos® Interactive Window System for passenger cabin window shading.

Designed to replace conventional plastic pull-down shades, Alteos® interactive window systems afford operating efficiencies while putting passengers in control of their environment.

The world’s first electrochromic window shades for commercial aircraft passenger cabins, these advanced systems switch from a bright clear state to a darkened state or a comfortable intermediate level, all at the touch of a button. Passengers can enjoy expansive views from their seats without annoying glare for a feeling of openness in the cabin. Or they can darken the window system at their seat to keep light out. Alteos® Interactive Window Systems are self-contained with no moving parts and lightweight, making them easy to maintain.

Alteos® Interactive Window Systems are lightweight, self-contained assemblies with no moving parts, making them easy to maintain.

An electronically dimmable panel is installed between the inboard dust cover and outboard structural cabin window system. A window-seat control allows the passenger to activate the system and change the amount of visible light transmitted to maximize it, minimize it or select an intermediate setting. Passengers see only a stylish window and control button. With Alteos® interactive window systems, keeping the cabin comfortable is easy. Ultraviolet and infrared radiation transmission are reduced, lowering the heat load inside the cabin and enhancing the operating efficiency of the aircraft’s heating, ventilating and air conditioning system. If desired, the interactive devices can be linked via the onboard network to allow for flight crew override and continuous monitoring of system performance. Should a power loss occur, the window systems default to a clear state to maintain maximum light transmittance, ensuring compliance with aviation standards.
