How are propeller / engine RPM restrictions determined?
What sort of equipment is used?
Can a the equipment for propeller balancing be used?
Just Curious
i came across the same problem as Ed. I do have to determine the RPM restrictions for my setup (IO-375/Hartzell CS 72") for the POH.
Is there any way to "feel" the RPM ranges during flight? Or are that vibrations something only the propeller notices? so that only the prop manufacturer is able to figure that out in a test cell with some fancy equipment?
