How to measure power in a simple single?
Hi, I fly a PA28-180D, with a Lycoming 0-360. It has a non-standard 'climb' pitch prop. I was reading up about leaning the mixture in the cruise in the POH and it cautions against leaning at power settings above 75% power.
Any idea how I work out what 75% power represents so that I know that I can lean the mixture safely ?
Many thanks,
Andy
