Hi All,
After going through the hook up procedures with a trainee I always ask ”is this
what you would do in a real emergency?” The answer is always yes. I reply “what
about using the radio – much safer” The GFA manuals should be brought up to
date. The effort for many years was to avoid making the carriage of a radio in
a glider mandatory and all procedures assume a radio is unavailable.

The weak link MUST be placed at the tug end of the rope, otherwise it can’t
protect the tug in the event of fence strikes.
We used to use a short length of 6mm rope as the weak link which was less risk
of damaging the glider if it were to fail.
However we have now moved from this method to the more precise Tost weak link
with the calibrated dual links.
One thing I would suggest is that the Tost link is attached so that if it fails
the housing of the weak link stays at the tug end, which means less bits coming
back towards the glider!

My experience is a weak link at the tow plane end where it does not get damaged
by wear (dragged on ground at landing) etc and if a light glider is used then
maybe another weak link is clipped in to end of rope at glider end. I am not
too keen on extra weight on the glider end of rope as could do damage to glider
canopies. I believe it cut badly into rear of wing of glider and rope
eventually broke near the tug. I am sure somebody will fill us all in
eventually

Though I don't understand much about this specific incident, surely having the
rope wrapped around the back of the wind would cause some of the load in the
rope to be distributed into the wing itself? This would mean the section of
rope between the wing and the hook would be under less load than the rest of
the rope and therefor the weak link wouldn't break?
Just a theory

There is a brief report on GFA web site but no mention of why weak link failed
to break before the damage was done. I am not trying to upset club members.
