cruise rpm

Thank you, Henry! Good advice at all times. I understand better now.

I notice that even in this weather my RPM often drops during the mag check due to carb ice. . I need carb heat to complete the mag check and restore initial RPM.. I always give a 10-15 second shot of carb heat immediately before taking the active. If RPM decays in flight, the first response is to pull carb heat. That will usually cure it. If not, check fuel, oil pressure, cylinder head temp, ect.

Thank you, Alan! I get puzzled about these things sometimes, thank you for your good reminder. Don

Thank you, Henry! Good reminder. Doon

The minimum RPM is a static RPM. 2050 rpm is minimum Full Throttle static run-up rpm.

Normally not. Under extreme conditions, carb heat may be needed at any power setting.
