A/C is an RV-9A with a O-320, Sensenich fixed prop limited to 2600 RPM and a D180. For best % power accuracy, what should the recommended green to yellow and yellow to red setting for tach be? This is not equipped fuel flow, so it sees MAP, altitude and altimeter, and Tach.
Forgraphical reasons, I would like the yellow to red to be 2600, but I’m not sure if that will skew the results.
I’m not sure I believe what I have now, in that 2300rpm, 20.6 in MAP, 5460 p alt/5240 d alt, 6c OAT was showing 64% on the display. I believe that to be closer to 50%-55% from the Lyc charts. I was showing 132kt indicated, 142kt TAS at the time.
Thanks, Rick
