Had an actual rope break (uncommanded relase of tow rope from glider it turned out) at 200' above the ground. 83B is the tow plane, Albert is a British C-130 doing touch & goes at Inyokern at the time.

Electrical crosstalk is a type of interference where the signals carried in one set of wires "talk across" into another set of wires. This video sets up a simple glider electrical harness that exhibits crosstalk. The harness is constructed using unbalanced signals, e.g. signal pairs that consist of a signal line and a ground return. The construction of the harness is then varied to determine the extent to which the crosstalk can be reduced.

My last post titled “The Risk of Dying Doing What We Love” presented the results of a statistical analysis where I compared the risk of flying sailplanes to other things we love to do such as cycling, horse back riding, paragliding, etc.

I showed that the risk of dying in a soaring accident is approx. 1 per 50,000 flight hours, which makes soaring per activity hour about 2x as dangerous as riding a motorcycle, 25x as dangerous as cycling, 40x as dangerous as driving a car, and almost 200x as dangerous as traveling on a commercial airline flight.

The post struck a core. Within just a few days, it was read tens of thousands of times and many of you have shared your thoughts and asked really important questions. Perhaps the most important ones were:
Does soaring have to be so dangerous?
How can each of us make it safer for ourselves?

Soaring does not have to be so dangerous.  If you train your brain to resist the temptations; if you practice and are self-critical; and if you are diligent before and during your flights, you can dramatically improve your odds.

Electrical crosstalk is a type of interference where the signals carried in one set of wires "talk across" into another set of wires. This video sets up a simple glider electrical harness, talks about how crosstalk might occur in it, demonstrates it occurring and illustrates the magnitude of the consequences to the pilot.
