Does anyone have or know of a program/ spread sheet that will do this for me? I would be very grateful for a copy. Alternatively, just some practical cruise settings. I would like to be able to set up less than 75% or 65% power, confidently, outside the prop avoid band at a variety of altitudes. Ideally it needs to be for an O-320 but I expect % power would be very similar for an O-360 Thanks, Steve. #90360 G-IINI -- Internal Virus Database is out-of-date.

My WOT RPM equates to about 145 HP and this would account for a couple of knots, and I found that most people believe that Van's numbers are a little high. After accounting for this, I got more comfortable with my planes' performance. Besides, I really don't need to go that fast!...Dick Jones ----- Original Message ----- From: "John Spicer" Subject: Re: RV9-List: Rpm on 0320 > --> RV9-List message posted by: John Spicer > > That sounds like a good TAS, why are you disappointed? > > -- John S. > > do not archive > > > Richard Jones wrote: > >>--> RV9-List message posted by: "Richard Jones" >> >>Neil: I have an O-320 with a Sensenich 70CM with 79" pitch on my 9A, and >>my >>numbers are virtually identical to yours.
