I just had an idea for a hook in check system that I thought might be new ... until I searched the U.S. Hawks site and found Bill's post from December 11th, 2011 and Terry Mason's post from December 12th, 2011.
My idea was some means of making part of the harness suspension visible when launching. There are lots of ways to do this, but my current thought was a simple elastic band permanently attached to the harness that would be routed to an attachment point on the keel within the pilot's view (the routing might go around the king post to keep it streamlined with the keel). The procedure is to hook in and then attach the elastic band. The attached elastic band is visible while launching.
But when I searched the U.S. Hawks forum, I found it to be very similar to Bill's idea and Terry's report ... from seven years ago. Thanks Bill and Terry!!!
As with any system, there are failure modes. The most obvious are:
- Attaching the elastic band without actually hooking in.
- Not noticing the unattached status right in front of you.
There are surely other failure modes as well, but I think these are the most likely. The second mode could be reduced by using a dangling ball or flag (as Bill and Terry suggested) as part of the attachment point. When it's not attached it would be dangling loose right in front of the pilot's eyes.
As mentioned, any system has failure modes. One can, for example, simply forget to "lift and tug" (when using the "lift and tug" method) or forget to "always launch with a tight hang strap" (when using the "always launch with a tight hang strap" method). Bill's and Terry's suggestions are more foolproof since the dangling red ball/flag is less likely to be forgotten than something that's essentially invisible. I will try to experiment with this system at Dockweiler ... if I don't forget.
Footnote: Terry Mason left us in an accident nearly 6 months after his post in this topic. The legacy of his gifts to hang gliding are still with us in this forum. Thanks Terry.
