Spins, Spiral Dives and Training

A glider in flight should really never come close to a spiral, since
it is approaching red line fast. I feel the reason gliders get into
spirals is not only the lack of spin recognition of the pilot, but
poor flying technique. Yaw string, airspeeds, coordination.

You could say exactly the same thing about spins.


Of course all those problems can happen to a pilot becomming sick,
passing out or similar. I have programmed myself to immidiately pull
the trim all the way back and let go of the controls. Not sure if
that would help, depends on the ship?

I suspect you are being very optimistic that you could do anything to
avert disaster. You might pass out, or you might be in so much pain
that you are totally incapacitated. I can't see what the point of
trimming all the way back is, either.

If you trim well back and add as much drag as possible using
airbrakes, wheel down etc and get off the controls then you will
probably get a fairly stable and low speed "benign spiral" which may
even be survivable on contact with the ground depending on what you
hit.

Try it in your own ship at altitude and find out.

My personal view is that there is sufficient evidence to show that the
Puchacz is a dangerous glider, so dangerous in fact that it should never
be flown again.

It's actually pronounced poo-hots BTW, but I'm not sure how it
translates in plurality... regardless, it is odd how many have drilled
into the ground with competent pilots and instructors onboard though.
Of course there's the rudder pedal theory (rear pilot's feet
obstructing mechanism's full travel...), but it's just that- a theory.

Sorry bout that... I can't figure out how to publicly post it yet, but
I can email anyone that PM's me a copy of it if they like...
