Which engine condition is to be avoided when operating a constant-speed propeller?
A.Low RPM with low manifold pressure.
B.Low RPM with high manifold pressure.
C.High RPM with low manifold pressure.
I'm a little confused and having trouble figuring it out.
Any help would be appreciated!
Thanks all!
This can be compared to driving a manual transmission car.
Think of the prop as the wheels on your car. Think of the manifold pressure as the position of the gas pedal. Is it harder on your engine to:
A. Be going slow with the gas pedal near idle
B. Be going slow in 6th gear with the pedal floored
C. Be going fast with the gas pedal near idle
