How many gliders can recover from a spin which starts on the winch

Sorry to repeat myself, but how many primary trainers really DO enter
an unintentional spin during a winch launch with an instructor on
board?

Why do people think instructors are invulnerable? I know instructors
who've destroyed gliders.


In my opinion a primary trainer (the one that is used for early solo
flights) cannot be spin-resistent enough.

That was the rationale behind the K21, which was designed to German
requirements. Unfortunately all single seat gliders will spin, so
training solely on spin-resistant gliders is a receipe for disaster
and has no doubt cost lives. The Pooch is an excellent training glider
as it does what any single seater will do - spin if provoked.

Tales of "unrecoverable" spins in pooches are probably due to the idea
that the low tail can blank the rudder (actually it won't). In reality
a pooch will always recover with standard spin recovery technique. If
you claim otherwise, please provide a reference to an accident report
stating so.
