Hello,

Can anyone say for sure whether RPM stays the same with elevation or whether it will decrease the higher you go? (mixture being accounted for and leaned at the higher altitude) I seem to recall you'd get max RPM on a Cessna 172 until around 6 or 7000 RPM and then it would decrease but then that is a 4 stroke engine as well.(and it's been many years) Has anyone flown at different elevations and observed a difference in max static RPM?

Thanks,

Chris
