It probably wasn't clear from my initial post because I only pasted a small passage of the article. Reading it in light of the whole article, I don't think Mr Prouty was suggesting you let RRPM decay at the entry. His suggestion is to use the kinetic energy from forward speed to obtain the same result as had you used potential energy to keep the blades spinning. So theoretically this should still keep RRPM up after engine failure without actually lowering the collective. Still, sounds a little
to my extensive
inexperience, even if I can see the theory side of it
Off subject, whats the general consensus on constant attitude autos? Show boating, or a genuine (better?) way to do them?
