I need to develop a chart with operational power settings, i.e
Altitude/RPM/MP/ Power Developed.
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.

Here you go... it's for an IO360, but it can be modified for an O-320
using the data in the Lycoming operators' manual.

I'm wondering if any one out there could tell me what kind of rpm's they are
getting on an RV 9 A. On climb out I'm getting around 2250 and wide open I'm
getting only up to 2540. At 8000 ft I indicate 148 knots . I'm running a
sensenich 70 inch 79 pitch metal prop.

Neil: I have an O-320 with a Sensenich 70CM with 79" pitch on my 9A, and my
numbers are virtually identical to yours. I have flown a triangular course
at 8000 MSL, Barometer-29.72, OAT-62F., 1450 lbs. and came up with 153 knots
at an RPM of about 2570 RPM. I was initially disappointed based on Van's
numbers but I got over it. Most of my flying is at about 2050 RPM where I
can make 120 KTS on 6 gallons per hour.

That sounds like a good TAS, why are you disappointed?

Niel,
I have the O320, 160hp with the same prop. My four way GPS run at 8000', was
a max RPM of 2580 and 187 mph (162k) average speed.
My initial take off RPM is about 2230 RPM at 5600' airport elevation.
Some additional data I took at 6500', 47 degrees was:
RPM IAS (mph)
2400 155
2300 148
2200 143
2100 138

I was initially disappointed because Van's preformance specs. indicate about
165 KTS TAS with a 150 HP engine at wide open throttle. 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
