How reliably do CG hooks disconnect when the angle of the ropeexceeds the autorelease angle

A quick way is to only use a TOST ring set where you can still read (most) of the TOST part number stamped on the side of the small ring. With dimension change due to wear&tear, the part number will become unreadable.
This has the dual benefit of also ensuring you are being hooked up with a proper TOST ring set and not a home made or repaired set.
PS- Remind me to take a calipers out to the airfield next visit and validate a suspect worn ring’s dimensions. Thanks, whoever posted the spec dims.

It's on the oval ring on my ring pair... and TOST is stamped at the bottom of it.

While inspecting, look for small (maybe 1/32 inch?) cracks.

That seems to happen before noticeable wear changes.

Hi Dan

The winch driver was an older gentleman and he bailed out of the winch. I suspect lack of familiarity with the cutting system and a sense of his own vulnerability prevailed. Since then a more robust training system is in place for winch drivers

Us older guys need to step up our game!
