So the closest flap setting within the game to the POH recommended combat flaps setting is either the second or third notch.
The flap positions in the game are at 0, 0.2, 0.4, 0.6, 0.8 and 1.
The 0.5 setting clearly falls between 0.4 and 0.6 the second and third position.
So the area wasn't really needed to arrive at that conclusion.
