The answer is, yes, the PDA screen protectors does help screen
visibility in our very bright cockpits. The reason is that a standard
screen is made of highly reflective glass and will reflect both you,
the cockpit, clouds, etc, in the screen.

Be sure to remove dust and dirt before you put the screen protector
on. Just follow the directions. I use Boxwave (http://
http://www.boxwave.com/products/cate...rotectors.htm). All of
these covers are easily removed if you don't like them.

I also have made a simple three sided black sun shield to improve
readability.
