Hi All,
From a practical point of view re pilot control of a winch self -launch, I
would imagine the interesting bit would be foolproof control of - wind in
and appropriately stopping - the cable after release from the glider! I
understand that there is equipment available working on 2400 MHz that might
do the job?
Some of you may remember Bill Lewis (Cirrus GAM), who often worked for a
living in the far outback regions of this country. Bill sometimes took his
glider and winch with him, just to keep his hand in. He told me that he
would flag down "somebody passing by" - apparently there weren't a lot of
locals - give them a quick lesson on winch driving, and away he would go!
Maybe that was sometimes - usually these tales were told late at night, and
the detail tended to blur, if you know what I mean! I seem to recall that he
once told me he had done a rough estimate of launching costs - what a
masochist! - and it worked out at about $800 per launch! There was the odd
miss-adventure you will understand! Bill was an exponent of rope launching,
and he told me he was the only "long line fisherman" ever to work out of
Central Australia!
{Annie, it occurs to me that there if you can contact Bill and convince him
to put pen to paper, he will give you enough thrilling stories - not
necessarily entirely about gliding - to fill a book, let alone an article or
two in Soaring Australia! If this is of interest, I suggest you try
contacting Bill though David Nugent of the Sunrasia Gliding Club.}
Regards,
Gary

Hi Mike,
We have speed conrol from the glider right now. Its called a VHF radio
with
a press to talk button on the control column and a boom mike. Calling
down
speeds to the winch driver is not that hard. Not perfect but we have the
technolgy in most gliders. Just try and convince the GFA. They insist on
all
winch launch signals being given from outside the glider even though no
problem with wing down aerotow retrieves. The word antedulvian springs to
mind,.

Doesn't have to be electric.
I've long been an advocate of putting the winch throttle in the
glider pilot's hand.
Sure beats using semaphore with the glider airframe.

This would be interesting, but controlling a big electric winch.
Good for weekday fliers who don't have a motor glider.
They would have to be independant operators though. Would'nt they !
