Why are most constant speed equipped single engine aircraft non-feathering?
My initial thought was that the engine might still be operating with a loss of governor oil pressure, so having the blades rotate to fine pitch by default ensures that you wouldn't lose the engine (which might theoretically still have normal oil pressure).
Could anyone speak further to that design philosophy? Given a total loss of engine oil pressure, wouldn't you increase glide range given the ability to feather the prop?
