Targetware is such a joke it's not funny. Engine settings, cooling rates, cooling flaps drag, are all constants. You plug in very very basic parameters and the game engine makes a blanket statement about how it will work regardless of how it really did work.
TW is so messed up that game "builders" are fighting their own code on everything from damage modeling (parts are stronger the heavier a piece of the aircraft is, for example) to engine modeling (most planes coded in the game don't even have documentation from the people coding them, about what the max continuous settings are, max WEP, max cruise, etc, they don't even know THEMSELEVES and yet we accept that they are qualified to code the planes for us?).
Don't even reference that game when it comes to "reality".
