In my extensive collection of books I have got one, "Stalls Spins and Safety" by Sammy Mason, which adresses this issue in one of its paragrahs.
Now I have moved abroad for pension and have most of my stuff in boxes due to lack of space. Just in case somebody has the book i'd appreciate to let us know.
When I have a moment I will go in my garage and see if I can find it.
It adresses both climbing turns and descending turns if my memory is correct.
One point though, during my flying career (As a hobby, it was not my profession) I have owned many aircrafts, all aerobatic, and I have tried to correlate aerodynamics effects experienced in flight with the fundamental of physics being fond of the subject.
Subject that even with the correlation between theory and practice can still leave many questions unanswered to me. That is why also above I mentionned if there would be a test pilot somewhere who reads this, to get involved. Cheers to everybody, am happy to find out there are many passionate and knowledgeable pilots !!!!
