I have a limited exposure to spins (I've demonstrated spins or received

six different occasions). I have a commercial certificate (although you
wouldn't think so from my demonstration
of a chandelle). Maybe I did have to demonstrate a power on stall
while in a climbing 20 degree bank, once.
As I recall, we survived it.

I return to the original question: if the ball is in the middle will it
spin?

Becuase I believe snowmobile suits are for snowmobiling and not for
flying I won't have a chance to explore it
with an aerobatic instructor and an appropriate (but drafty) airplane for
a few months -- so I thought I would
put the question in a bottle and throw it in the ocean.

And courting disaster doing a chandelle? If you're going to do a

incipient spin shouldn't even make you break a sweat.



The answer to the ball question is no. It won't spin. A ball centered
airplane in a climbing turn is compensated by rudder and is considered
coordinated (in the classic sense).

If you introduce a climbing turn stall with the ball centered, you might
get a temporary wing drop at the break but unless you introduce a yaw rate
as the stall breaks; no yaw rate...no spin!


My thought is that we're splitting hairs in this thread. If the airplane is
in coordinated flight and stalls straight ahead (no wing drop), a spin can't
happen. But on most aircraft, one wing will drop first even if the ball is
centered. This wing drop creates a yaw, opening up the possibility for a
spin.
