Keep your hand off the release handle during aero tows!

Couple of things;

1) THIS THREAD IS ABOUT YOUR HAND ON THE RELEASE! NOT ON THE SPOILERS! Can we all say "oops"?

2) I had a PTT when I had my hand on the release. Never again.

3) That being said (#2 above) I saw a friend get in trouble on tow and couldn't find the release handle due to G forces (scratch one glider). So I came up with a fairly long lanyard that goes from the release knob to my wrist. In this way small movements of my hand won't impact the release but, in an emergency, a half way hands up gesture of "you're under arrest" will release the tow. Luckily I have never used this. Needless to say I use the knob for a non-emergency releases. Here is a link to my Mark 1 version (Bumper type model numbering), I don't have a shot of Mark II with its adjustable palm knob and black nylon webbing. http://aviation.derosaweb.net/images...selandyard.JPG

Sounds like a decent idea, John, but I think you should actually try it at
least once in flight. The act of raising your hand ala "stick 'em up" is
different than a straight back pull so I think you should see how it feels
and if it really works.

Intuitively, it looks like the gesture you mentioned would result in about a
45 degree upward pull on the release. Would the cable jam in its fairlead?

The release knob in my LAK is a fairly small disk, about a half inch (maybe
a bit more) in diameter and might be easy to miss in an emergency. I think
I'll give your rope idea a try for myself.

The lanyard loop is a fairly old solution that, I understand resulted from Gerhard Waibel not being able to get to the release on a '20 at Eagle Field resulting in a crunch of sorts. Interestingly, the releases on all his following gliders are up on the left and easily seen and gripped.
For 19's and 20's and such, we make a loop out of about 24 inches of parachute cord that loops around the release handle. The pilot lays this across his left thigh, and the release is easily found and pulled if needed quickly.. Holding the loop with slack would present minimal risk of accidently releasing and yet provides the benefit of quick access.
People adding to other ships should consider what such a loop may interfere with when implementing.
I guard the release during the early part of ground launches, but stay away from it on aero tow.
