I teach the sneaky slow low banked turn with student looking into the

(where are the "pilots" looking when they spin on base to final?) while I
have them try to force "just a little more turn" while very subtly
sneaking
in some more inside rudder. When it goes, they are surprised. That is
the point-
it comes as a surprise, especially when the pilot isn't watching the
attitude
and yaw.

Add a bit of a gust or shear, and it is even more sudden.


Question- "how would you like to do that low?" gets the predictable
answer.


UH


What glider were you flying?: We tried that with an Blanik L13, and
couldn't
get it to spin without using the normal highly exaggerated control
inputs -
stick all the way back and full rudder.


Remember, it's not the fully developed spin that's the *goal* of UH's
exercise. It's the sudden/unexpected *departure* that surprises
people...and if occurring low enough often leads to death. How many of
this year's North American below-pattern-height fatalities involved a
fully developed spin, I wonder...

In a related vein, there may somewhere be a 2-33 - everyone's poster
child of a "will spin in a heartbeat" glider, right? (Not!) - that can
be forced into a fully developed spin while within its certified CG
limits...but I've never encountered it. OTOH, every 2-33 I've flown WILL
do a "nice departure" if snuck up on as UH described.



Couldn't get the L13 to do that.
