RE: the carb icing temps at +6, that as far as the real world is concerned would be a normal parameter. Carb Heat should always be selected in a carburettor fitted piston engine aeroplane with temps from +5 to -5 and below with and here is the stress point, VISIBLE MOISTURE PRESENT, that is cloud. So that parameter is correct as far as a real engine would behave. In the real world carburettor icing forms within the carburettor and is caused by the venturi affect through the throat which accelerates the air mass and hence reduces its temperature so if moisture is present it will being to form as ice within the carburettor, the application of carb heat introduces hot manifold air back into the carburettor. It will also change the MP reading slightly so if you see that as well you know it is working. Not sure how this is simulated in the FSX engine but they seem to have captured it ok as I have had engine failures in the sim from carb icing.
