Turning the Prop
Recently, some bloke said to me that he turns the prop on his plane to lubricate the internals before starting the engine. He reckons this helps keep the engine in fine fettle.
During my PPL I was taught to treat the prop as live at all times for what seems to me to be very obvious reasons considering the way the mags work. However, I just watched Airsport on Disco Wings and it showed an aerobatic pilot doing the same thing to his SU-aero-wotsit-big-engine-little-plane prior to starting it.
Is there any benefit?
