Help with Prop Governor Theory
I'm getting ready for my COMM SEL ride, and feel pretty much ready for most of the oral except for 1 thing-Prop governors. First off, I'm taking the ride in a 172, but we still need to know landing gear, prop governor, and pressurization systems (and feel free to let me know if I missed anything else). What I get so far about governors is this: props change pitch by means of oil pressure through the governor. In a single-engine, increased pressure=higher pitch/low RPM and vice-versa for decreased pressure. But I don't know where to go from there as far as explaining it for the oral. Any help would be much appreciated. Thanks in advance.
