Hello all,

I tried flying at the long range cruise per the power setting table. I chose 23 / 2300 RPM and 13 gals each engine per the fuel flow graph on the manual. TAS was 163 at 10500 on a hotter than std day.
The question is when you are climbing at climb power, after reaching your alt and level for cruise what is the advisable way to get down to 23 inches MP, all in one movement or slowly to prevent excessive cooling? I did it all at once but the JPI showed -47 in the cooling page. Was this too radical?
