RPM speed

[sonas]

Recently flew a short trip and thought i would check out flat and level at 2000 feet -6 flaps

rpm was 5800

any idea how much to add to get it close to 5500, i know i can get it but it will take me 3 tries...maybe you guys can narrow it down to 1 or 2!

 

thanks

which prop?

Probably in the neighborhood of 1.5 to 2 degrees.

What was the density altitude?  55 at 2 would be too coarse for me.  55 at 7.5 makes a nice minimum pitch. It matches your best performance altitude with your best speed pitch.

Hi,

Since your current RPM is 5800 and you want to lower it to 5500, you'll need to decrease the throttle slightly. Start by reducing the throttle by about 5-10% and observe the RPM change.

 

Thanks

Well said, Mr. Roboto.
