I have a question for the veteran BF-109 technicians on this forum:
Does that actually work IRL? I mean, can you change the prop-pitch without a hydraulic pump running? Most prop pitch devices I know are operated by means of flyweights controlling valves that adjust pitch according to demanded pitch, and only works when the engine is running. Most modern planes, I believe, have a spring device set to push the prop to coarse (feather) pitch if the variable pitch unit or engine is lost.
