ABSTRACT:
A aircrew controllable sunlight filter for preventing sunlight washout of aircraft instruments comprises as part of an otherwise conventional laminated aircraft transparency an additional ply or layer of photosensitive material positioned near the inside of the transparency. An ultraviolet light source aimed by an aircrew member at a part area of the transparency will cause the transparency to darken and reduce the amount of visible sunlight striking the aircraft instruments.
