Hi GroundBound

Errr.... what's the pitch lever for then?
The pitch lever is used to set the RPM you want. Example: you are crusing at 24" MP/2400 RPM and you decide that you want to reduce power to 20" MP/2000 RPM, then you would:
  • Use the throttle to reduce power so that MP indication reduces from 24" to 20"
  • Now use the pitch lever to reduce the RPM from 2400 to 2000... if you don't, it will stay at 2400 RPM all by itself...

There is a maxim to remember: "Rev Up, Throttle Back" i.e. when reducing power, the throttle goes back first. Conversely, when increasing power, the picth lever goes up first. So, to increase power from "20/2000" back to "24/2400" you'd:
  • Use pitch lever to increase RPM to 2400...
  • Then use throttle to increase power back to 24" MP

Obviously, this is just an example and you should always check the POH!

Hope this helps,

Andy
