This question is more a matter of curiosity than anything else. Still, it's driving me nuts for no good reason and I figure that somebody here knows this inside and out.
As I understand the attached propeller load chart, the curves PROPELLER LOAD SPEC. FUEL CONS. and PROPELLER LOAD CORR B.H.P are paired as are FULL THROTTLE SPEC. FUEL CONS and FULL THROTTLE CORR. B.H.P.
So I might ask myself what's the fuel consumption and HP at full throttle and 2300 RPM. Using the FULL THROTTLE curves the fuel consumption would be ~.545 lb/hr/hp and the HP would be ~122. Is that right?
So let's say that I pull the throttle back 1/2" and we arrive at 2200 RPM. Do I now use the PROPELLER LOAD curves to come to the conclusion that the fuel consumption is .475 lb/hr/hp producing ~79hp?
It seems like I'm missing something obvious to everybody else. If you multiply out the numbers on thee PROPELLER LOAD curves you are very close to the published performance numbers for that engine.
