SR20 Cruise Speed

Guest Discussion

I have 130 hours on N2578B, and have yet to exceed 152 knots true airspeed at 75% power. I’ve figured it out on the 430’s as well as the airspeed indicator, and have flown altitudes up to 10,000 feet.

Others’ experience? Advice as to what can be done? I keep it clean. Could humidity be impacting the speed or the calibration? Forward CG?

Interested in any input.

One thing to check is the prop governor setting - make sure that you are actually getting 2700 rpm with the power lever full forward. In any case, if you get 155 KTAS at 8500’ you will be doing as well as most. The book figures are optimistic, in my experience.
