Do airline pilots get sunburn in long haul flight? If yes, then how do they protect themselves?
Finally, does the windshield of newer aircraft (eg: Boeing 777, 747-8) block out more UV radiation?
I read that flying, especially at high altitude, can increase the risk of skin cancer significantly. But, I also know that windshield is laminated and has a vinyl inter-layer that should block out most UV rays (both type A and B). Unfortunately, UV intensity does increases with height..
I have limited flying experience (two introductory flight lessons in a Cessna and several commercial flights, including some Transatlantic trips), so please excuse my ignorance.
I was wondering; since the earth is spherical and the curvature is approximately 6 foot "drop" for every three miles i.e. a 6 foot person will disappear over the horizon 3 miles away, does a jet aircraft need to be constantly adjusted nose down to adjust for the curvature of the earth?
In other words, if a plane was trimmed for straight and level flight, would it "gain altitude" while flying as the earth surface "fell away" due to the curvature?
