Hey all
Just wondering if anyone knows how cockpit windows are treated to protect against UV radiation and how much they screen out.
My understanding is even normal window or car glass screens out UVB and UVC. It reduces the levels of UVA but not does not eliminate it, so you can still burn through this glass.
I would think the high-dollar windows on transport category aircraft would do better than that, as well they should considering the high altitudes we operate at, and thus the stronger levels of UV at those elevations.
Specifically I'm wondering about the Boeing products and the older Lears with the thick Plexi windshields. I hadn't given much thought to this until I started flying behind those greenhouse windows in the Lear. I had the sun on my side the other day, and it was so warm on my arm I could almost feel it cookin'!! Infra-red is one thing though, UV is another.
Any info appreciated.....
