Default Overspeeding on winch launches

https://members.gliding.co.uk/bga-sa...safe-winching/

The BGA has published a an excellent winch launching resource.

Well worth memorizing at the beginning of every season.

The winch driver should be reducing power at the top of the launch as this
is
where overspeed becomes critical.

Do remember to have a correct weak link.

I managed to break one just as I was releasing. Gusts and transmission
surging
can add loads. That is what the weak link protects against. The
manufacturer
airspeed limit gives some margin for gusts; so yes, on a calm day a small
airspeed exceedence might not break the weak link. But don't make it a
habit.

We qualify in a 2-seater, but a single seater handles differently. The
winch
generally has to run at the max for a 2-seater, but has excess power for a
single
seater.

Tension can go up or down a few hundred pounds in very few seconds because

of gusts.
