Constant speed prop behaviour with power lever at idle.
Hi folks,
Wondering if anyone can help answer this query re: prop and governor behaviour and please correct me if I have got anything wrong.
Whenever I have flown constant speed prop aircraft (which hasn't been that often), the engine is usually started and shut down in fully fine pitch i.e. blue fully forward. I assume the prop is on the fine pitch stop at this time. Likewise prop checks are normally done with the prop at the required rpm so that they are in the active range of the governor, therefore the rpm will change as the prop is cycled.
However, what happens if the prop is cycled (not suggesting it should be) whilst on the ground and the throttle is at idle? Will there be an increase in pitch and therefore a further drop in prop rpm or will the rpm remain the same?
Thanks in advance,
Rich
