Aircraft glazing units, such as those used to protect an aircraft's lighting systems, are exposed to particulate matter and water droplets during flight. These erode the outer surface of the glazing panel and thus detrimentally affect its transparency. The invention provides an aircraft glazing unit comprising a body of transparent material and at least one subsurface thickness indicator at a predetermined depth within the material. The provision of a subsurface thickness indicator allows for the unit to be re-polished to remove erosion, whilst providing a visual indicator to ground crew of the remaining thickness of material in the unit. In this way, the service lifetime of the glazing unit can be extended.

    本发明涉及一种飞行器透亮单元、比如那些用来保护飞行器的照明系统的飞行器透亮单元,该飞行器透亮单元在飞行期间暴露于微粒物质和水滴。这些微粒物质和水滴侵蚀透亮单元的外表面并且由此不利地影响其透明度。本发明提供了包括透明材料的本体以及处于该材料内的预定深度处的至少一个表面下厚度标示物的飞行器透亮单元。所提供的表面下厚度标示物允许在针对该单元进行重新抛光以移除侵蚀部同时,向地面工作人员提供标示该单元中的剩余的材料厚度的视觉标示物。以此方式,能够延长透亮单元的使用寿命。
