I’ve noticed that when I do my run-up on my friend’s C206, I set the rpm’s at 1800, and cycle the prop to no lower than 1300. My friend mentioned that he will continue to maybe 1200 or so. We looked at the Flight Manual and it mentioned only seeking a drop, but not a quantitative figure or number.
My question to you is:
- How much drop in R.P.M. is needed to cycle the propeller to make sure the oil is moving correctly?
- How much is too much?
- What dangers are there in either scenario?
Thanks in advance
