Use of carb heat in flight
What effect's other than melting ice and reducing power does adding carb heat have on the engine and plane?
The question arises because as far as I can understand, adding carb heat reduces power but by reducing pressure differential in the carb venturi it will also reduce fuel flow rate. So it's not clear to me how it will affect comsumption (per nm). Another point I came across is that adding heat will help to make combustion in each cylinder more uniform. From this should follow a more efficient burn and maybe less vibration and less engine wear.
