This is a very nice addon (or whatever it is)! It really adds a lot of realism for me! One minor complaint, though. You go to all the trouble of renaming the military vehicles, civilian vehicles, and weapons, but you forgot about the civilian plane! However, because I am a student pilot, and an immense lover of flying and airplanes, I can help you out. ;D
Contrary to what the BIS model says, the civilian plane is
not a Cessna 182 Skylane. Cessna 182 Skylanes have a three-bladed propeller. This aircraft has a two-bladed propeller. Therefore, it would be my educated guess that the plane made by BIS, having two propellers, four seats, a high wing, and a window in the back, is a Cessna 172 Skyhawk. Probably an "N" or "R" model, but that's not important.
Ok, now that I've said that, my suggestion is to rename "plane" to "Cessna 172 Skyhawk". Or, if that's too long, something like this might suffice: "Cessna 172N" or "Cessna 172R"
