It is actually difficult for us to teach proper spin
recovery in the Puch simply because it recovers so
easily.

Considering the sheer number of spin accidents with
instructors on
board of Puchacz I dare to doubt that statement.

Have you ever spun one? I will repeat myself, it recovers
from most spins with most cockpit loads if you let
go the stick, so on the majority of occasions the instructor
has to be vigilant that the pupil applies the correct
recovery or an incorrect recovery technique will have
been learnt.


The danger is that a pilot gets the impression 'all
I have to do to recover is relax the back pressure'
that'll kill you in a glider with genuinely nasty spin
recovery characteristics like the DG500.

DG500 nasty spin recovery characteristics?
Which ones? I'm doing a lot of spin training in the
DG-505 with 17.2m
wingtips and the spin behaviour is really nice.

The DG-500 is fully compliant with JAR22 when the CofG
is within limits. When the CofG is near the aft limit
it requires the correct spin recovery to be applied,
in the correct order, or the ground will do the recovery
for you, it will continue to autorotate with the stick
on the front stop if you just heave the stick forward
without first centralising the ailerons and applying
full opposite rudder. It may be possible to recover
by applying the full opposite rudder after heaving
the stick forward but it will be a delayed recover
due to control surface masking.

A pilot who has acquired the impression from the Puch
that all is required is to let go or relax the back
pressure could be killed in this situation.
