Question
When the propeller pitch check is made the RPM shouldQuestion 22Select one:a.Increase because the pitch has increasedb.Decrease because the pitch has decreasedc.Increase because the pitch has decreasedd.Decrease because the pitch has increased
Solution
The correct answer is d. Decrease because the pitch has increased.
Here's why:
-
The pitch of a propeller refers to the distance a propeller would move in one revolution if it were moving through a soft solid, like a screw through wood.
-
When the pitch of a propeller increases, it means that the propeller is trying to move more air with each revolution.
-
Moving more air requires more power. If the power output of the engine doesn't increase, the engine will have to work harder to turn the propeller at the same speed.
-
Therefore, if the pitch increases and the power output remains the same, the RPM (revolutions per minute) of the propeller will decrease.
