Danger Variable Pitch Propeller

Hello to all,

I'm stuck trying to understand how a Variable Pitch Propeller works on light single engine aircraft?

The thing that really confuses me is the difference between a CSU/PCM?

Which one will a Cessna 182 have and also can you feather a single engine a/c prop?

Also having flown the PA32.. I would take off at a fine pitch angle and after T/O I normally reduce MAP to 25 in and bring the propeller back to 2400 RPM for the climb.. once in the cruise I'll reduce the map but will stay at the same rpm until the decent. Thats what I've been taught but what happens when you bring the RPM back to 2300/2200rpm for the climb other than it taking a greater chunk out the airflow and increasing it'a drag? is there a reason to adjust the pitch of the prop at different phases of the flight or just leave it at 2400rpm?!?! No-ones unfortunately been able to explain this to me properly!

Safe Flights
