How does such a light glider comply with FAR 91.309 (3)?
It seems that anything being towed would have to be within the 80% and
2 times rule for the rope and ring strength.

Perhaps I misunderstand your question, but it complies with the
requirements like any other glider. The SparrowHawks I've seen towed use
a weak link and the standard towrope used by the heavier gliders. It's a
light weight link, of course, as you'd expect. You could also switch to
light weight towrope, but the weak link is usually the most convenient.


Isn't there a requirement for a weak link at the tow plane also or is
that just a recommendation? Thanks. Mike

If there isn't a weak link at the glider end, then there must be a weak
link at the towplane end. See CFR 91.309. It's only required at one end,
fortunately for the operators using retractable towropes.
