A lot of those packages are cockpit arts (British, German, ect) without those you'll get the defaut cockpit art for that plane type. For example the P-51 is the default art for fighters. Without other art installed, you'll have a 51 cockpit display no matter what fighter you are flying.
Cool! I mean that if you are saying I could have a 109k4 with the visability of a Pony that is.
