Effect of humidity on engines
I have been reading the FAA A&P handbook on powerplant, and somewhere there it's mentioned that humidity does no affect turbine engines (or has insignificant effect) compared to piston engines.
Why is this so?
Is it because turbine engines have automatic compensation or something like that in it's fuel metering system, unlike piston engines which only has a carburettor which does nothing about humidity (or even density, unless mixture lever is adjusted) for that effect?
