Whether or not the engine is "running" if the rpm is below this range,
moving the prop control has no effect on the pitch of the prop.


That's what I thought until I tried it on my 182. Idle power, trimmed

the blue knob back and watched the airspeed increase about 5MPH...pushed
the blue knob in and I slowed again.
