Good evening all
It seem to me that the attachment to my posing of earlier today never made it
onto the list.
It is a report on the spin characteristics of the ASK 21 and I assume this 6.5
MB document
was automatically withheld due to it size.
I’m happy to submit a copy to anyone interested

How many other gliders do this? I am pretty sure the Blanik self
recovers from a spin but have never tested it! :-)

Might be possible. The frequency of the AC component of the pressure and the
amplitude should change as the flow becomes turbulent. AC is good as offsets,
temperature effects don't cause problems. Silicon pressure tranducers easily go
out to one kilohertz frequency response unless they are the o

you've made this claim before. I assume it is another incident, not the

Here's one from the Canadian ATSB which references others.

In 1990, a Puchacz spinning accident that resulted in two fatalities was
investigated by the Transportation Safety Board of Canada (TSB). It was
determined that the glider had inadvertently entered a spin at
'As highlighted in the British Gliding Association report, the retention
of aft stick could be expected to be the involuntary reaction of the
pilot in such a situation. '
Could be a major reason why people are dying.

happening.

Thanks for that Derek, though I had seen the Canadian one and I was

Hi Derek
This is consistent with a briefing that the late Mike Valentine gave in South
Australia when the Puchacz first came on the market.
He commented that it loses 300 plus feet in a single rotation and becomes a
"widow maker" if spins are allowed to develop below
1000 ft AGL. The most frig
I've never seen an official NTSB report on it but it was reported on r.a.s. in
a thread on Puch spinning after another Puch spin in elsewhere.

I infer from this thread that the general view is that a pilot (perhaps more so
in low hours) has a higher potential to spin when thermalling or attempting to
thermal at less than 500' AGL than at higher altitudes.
If so, why? What behaviours and responses are different?

The horizon appears higher, and pilots in flatland sites are often taught
to judge airspeed based on nose attitude on the horizon.

Another factor is the perceived acceleration and changes to turn radius/rate at
low level if there is any wind about during a turn. The brain can see this and
subconsciously try to keep the picture constant by tightening the turn or
slowing down.

Hi Richard,
Fear of manoeuvring when low level might have an inexperienced pilot over
ruddering the turn. This pro-spin cross control in low level turbulent air
(higher "g" transients) can certainly drive one into an incipient spin.
Coupled with lack of spin currency hightening a natural fear when
So where did you get your knowledge of the Puch spin in at Cal city?

Were there any Puchaz spin fatalities in Australia? I know that DDSC used
them for spin training from mid nineties without an incident.
