In my experience flying a puchatek in WA,
The elevator has authority to lift the nose and hold the nose up on take off
about 10 seconds after the wing walker has let go as for a knot speed i
could not tell you as i'm ovviously looking out the window at that time.
As for landing the puchatek has a really bad habit in strong crosswind of
weather cocking no matter if you have some controllability, it gets verry
quickley to the point on roll out that any controll input is useless to try
and keep on the centre line.
The ailerons still work in the final stages of a ground roll , so putting a
wing onto the ground should not be a problem.
If we could get rid of the fixed nose wheel and have a castering nose wheel
with a lock on it , if a ground loop is needed pull the nose wheel lock ,
drop a wing and it should spin on the spot like a dream.
as for a speed to initiate a ground loop i would have to work that out next
time i fly it, i would hazard a guess in the 2/3 of the landing no later.

Hi Ian
Good point. No one has experimented to establish at what speed a Puchatek
(and perhaps many other nose-wheel gliders) lose elevator & rudder
authority. John Viney agrees we should do this experiment. If the LKSC
Puchatek is written off it would be a good opportunity to do this test - I
have passed on the idea to the committee.

I am not sure but believe there are certain nose wheel gliders that are
difficult to ground loop (KRO3A just goes straight when nose wheel is on
ground and no way can you steer it). Perhaps as such aircraft come into
the
country they could be fitted with the "dutch wire lifting bar" to inside
of
canopy as part of MAR1 at import (like pull up seat belts etc). The dutch
have done engineering and ALL dutch gliders have same. I do know Paul
Mathews had same fitted to one of his gliders when flying around Gulcong
and
said it is easy to get to use.
Just a thought...........Ian McPhee

Given the amount of incidents which have occurred with aerodrome
perimeter
fences especially in gliding, perhaps thought should be given to
changing
the design of these fences to make them more forgiving.
Possibilities may include some sort of weak link system in each wire or
perhaps sprung sections which may allow the canopy to deflect the wire.
I'm sure there is enough ingenuity within the gliding movement to come up
with some ideas to make these fences safer whilst still performing their
function.

Good call, Mitch.
The only addition I would like to make is that it seems the
pilot/instructor
had very few options... he was released at low altitude without enough
energy to clear the fence, and (thinking through the evidence I have
heard)
with a downburst happening somewhere behind him. This leaves him with an
increasing tailwind, and if he was touching down somewhere near the
stall,
he is approaching the fence with no control response, in a
nosewheel-equipped glider. He DID try to groundloop, with no response.
Very tough for all, especially the instructor.
BT.

Fair comment, Ron, however in this case we should perhaps refrain from
any judgement (deliberate or otherwise) until a more suitable time. I
would like to offer my condolences to the family of the student and let
my good friends at LKSC know that they are in my thoughts as they deal
with the aftermath of this accident.
Mitch.

Even if you have only got five feet to run before the fence YOU MUST
initiate a ground loop.
