Attached file is a fair reproduction of the performance chart found in the POH for a PA-28. The aircraft obviously has a CS prop.
Under both the 55% and 65% power columns, there are two columns for MAP, one set for operating at 2200 RPM and one set for operating at 2500 RPM.
When are the 2200 RPM settings preferred and when are the 2500 RPM settings preferred?
The only thing I could come up with is to use 2500 RPM settings if you might need a rapid increase in power. I'm really just guessing though, I have to expect there is more to it than that.
Thanks,
