First, if you're static RPM is consistently at the high end of the allowable range, it''s a climb prop. If it's at the low end, it's a climb prop. If it's in the middle, it's "just right". Or, find out what the recommended pitch is for that prop on that airframe with that engine. If that's what you've got, it's normal. Up to about 2 inches more pitch is a cruise prop, and up to about 2 inches less is a climb prop. Don't know what the normal pitch is? Refer to the item one. Awfull techie question for the social pages...
