| Does anyone have a copy of the powerpoint presentation from the advanced pilot seminar? I ask because I think for our plane running 50˚ ROP gives us the best performance. 50˚ LOP is the best fuel economy.
I have been collecting data especially on my cross country trip for our IO 550.
Basically at 7,000 feet I found that at 50˚ LOP I was indicating 170 KTS TAS and 150 KIAS.
At 50˚ ROP I was 179 TAS and 158 KIAS.
My EGTs/CHTs: 291/1435 LOP & 330/1431 ROP.
When I tried 75˚ ROP I slowed a couple of knots. At 100˚ was increased fuel consumption for no gain in airspeed.
Anyhow, I pasted some data below which was typical for the 9 leg trip across the US last week for our ferry flight. Also note, the plane is not painted, which may bear differences for our ES vs others.
