Steep Sprials - Why increase pitch when in shallow bank and vise versa in a steep
I'm in the process of doing a presentation for a group on steep spirals. My question is as follows.
Through various resources (AFH, Google, Instructors, etc) the common knowledge item is to decrease pitch on the downward side of the maneuver (steep bank) and to increase pitch on the upward side (shallow bank) to maintain airspeed. For the life of me I can't think of the physics behind it...in fact I think it is opposite...
From my experience, in a steeper bank the plane wants to accelerate because you are loosing more altitude...so why would decrease the pitch to accelerate the airplane even more?
Very confused...but I appreciate any help.
