Here's a cool mod for anyone who has as bad memory as I do:
PeterP's Kneeboard Tablet
Basically, you can add images to a folder and you can then cycle through them in-game.
For A-10C, you only need to install the base. In the "KNEEBOARD_MOD_PeterP"
folder, you'll find "common" and "custom" charts. Common charts appear in every
aircraft (remove them from the folder to get rid of them) and inside Custom charts,
you have folders for different planes to where you can put plane specific charts.
Handy.
(I totally filled it with boobie images)
