It's not meant to sound facetious, I'm just doing my own quick research. I actually mean the phase of flight.
Yep, I also think they should be jumped across to the carb heat thread.
Circuit Basher, when you are doing your preflight carb heat check, then you will see an RPM drop despite the CSU. This is because the the RPM is outside of its operating range. There is only a limited angle that the prop can move in, basically the prop will be as fine as possible.
In flight, you will get an initial change of RPM with the application of carb heat this is due to the loss of power and the lag in the response of the CSU in fining off the prop to keep it at the required RPM.
