Re: 2 recent incidents

How many more of those we need till we conclude that the rudder
> waggle does NOT work? 

I think this is a reasonably valid point.  There HAVE been a number of 
people who have misunderstood this signal.

Perhaps something else would be better.  The question is what signal 
would be a good replacement.  You could have fla****ng lights on the 
towplane, perhaps mounted just above the towhitch.  The only thing is 
you'd probably have to install two lights.  Say one yellow and one red.

Yellow means you've got a problem, but if you can get it fixed pretty 
quick we'll keep going.  Red means get off now or I'm gonna dump you.

If you don't have two signals, I'd bet that we'd still have people 
releasing when they didn't have to.

As I think about it, it might be best if there was a single array of 
high output LEDs.  When both "colors" of the array are "on" then you 
have a single visible color that means "ok" (red and blue make green in 
concept, but in emitted light that combination doesn't work).  That way 
the glider pilot can verify at the start that both signals "work" and 
they stay "on" for the duration of the tow.  If either the "warning" or 
"get off" switches are selected in the cockpit then only the 
corresponding "color" is then visible to the glider pilot.  Perhaps with 
the "warning" being a steady signal and "get off" being a rapid flash to 
help with fast recognition and a sense of urgency.

Other thoughts?
