Hi Michael,
Not sure of your winch status. The Brits after an extensive investigation
introduced “Safe Winch Launch”. Its principles reduced the winching accident
rate to 25% of what it was and has virtually eliminated fatalities. Worth
checking out their web site if interested. It uses 1.5 V
Hi Harry
The dual car system is working well, plenty of power, tension control,
no cable breaks, no drum tangles and quick turnaround.
How is your winch going ?
Compared to Australia, the BGA have done a lot of winch launching so it
makes sense to look carefully at what they had done.
I have re
Hi Harry,
Merry Christmas to you.
You have of course (and as usual), correctly identified the real
problem. It is safe speed near the ground. Maintain that and there
will be no chance of spinning. Spinning is a secondary effect of flying
too slow, yet somehow it is now the spin and not the

Hi Daryl
Would you mind explaining why? This is a genuine inquiry as my club is
about to take a delivery of one.

The report reminds us how useless the ASI is during spins. You are better off
judging speed using the noise levels assessed by your ears.
Why hasn't some instrument maker built a better
ied through AoA
or computing speed, g and wing loading etc.

Actually, I was thinking a flush mounted static probe rather than a pitot.
It would be interesting to see if a transducer could pick up the pressure
fluctuations from separated flow and be able to see the difference from
attached flow.

Might be possible. The frequency of the AC component of the pressure and the
amplitude should change as the flow becomes turbulent. AC is good as offsets,
temperature effects don't cause problems. Silicon pressure tranducers easily go
out to one kilohertz frequency response unless they are the o
Having gone through my training in Germany (perhaps a little more recently
than Rolf?) I concur with Rolf. The general syllabus was very similar to
what we have here, including incipient and full spin training. There was A
LOT more theory though.
