Hi,

I am trying to find a good online resource with instructions for assembling
a glider aerotow towrope. I can't seem to find anything. I suspect that
every soaring club has a document explaining how they make their towropes.
I'd love to have links to a few on my web site.

Best Regards,

all german gliders that I know about have a weak-link requirement in their operators handbook. I've always assumed US pilots are required to comply with the operators handbook and the FAA standards.
