typically 197 knots at 12 GPH. It is always flown at Wide Open Throttle
(WOT). The engine has greater efficiency at WOT and generates the highest
speeds this way. The problem is that in order to achieve 60% power, the
temperature must be considered. This chart allows me to look at the temp
of say 60 degrees and I know I must run 2340 RPM to make 60%. This is a
nice way to get comparative performance data to see how your airplane is
doing. This charts assumes no Ram rise. In reality the engine is making a
bit more power that the 60% target due to this effect
