Look up a util called San's FOV changer as well. It can change the aspect ratio to widescreen or even 3x widescreen if you use triplehead/nvidia surround or ati eyefinity. I use it and love it when I play IL2. Just a heads up.
Il2 was originally programed to use 4x3 resolutions, (and even has native support for triple 4.3 res... but that's another story).... and is different altogether from what I'm referring to.... check out his page.
