Actually, the roll and yaw are in opposite directions in an inverted
spin. The relative proportions of roll and yaw depend on the pitch
attitude (assuming a fully developed spin with a vertical axis of
rotation). It is a bit of a crap shoot to guess what a TC would be
showing. This is one of the reasons why I have a T&B, as I plan to
do quite a bit of aerobatics, and I can't rule out the possibility of
ending up in an inverted spin following a botched manoeuvre.
The fact that the roll and yaw are in opposite directions make
inverted spins quite disorienting. We tend to be more sensitive to
roll rate than yaw rate, so there is a tendency to misinterpret the
direction of spin. If the inverted spin is intentional, then you
probably know which way you are spinning. But, if it was
unintentional, the turn needle on a T&B is a good confirmation as to
which rudder you need to push.

Great Information Kevin,

I had no knowledge of those forces. The only inverted spin I was ever in

scared me so much that I have avoided such spins assiduously ever since

The more I learn about the TC, the better I like the T&B!

Thanks for the input.

I have some old thoughts on this subject that I posted on another list

several years ago. Would you mind if I sent them to you for your comment?

Happy Skies,

Old Bob
