Maybe, just for kicks, I'll try that in my LAK-17a at the end of a wave

Did you use full dive brakes?



To tell the truth, I don't recall - probably not. I think I used the

published (in Soaring) procedure but I don't remember if it called for

full

dive brakes.

My understanding of the "benign spiral" is the air brakes MUST be open
to

stabilize the glider and prevent over speed.

A couple of years ago I was in a particulars UK comp called Enterprise I
was
enjoying the comp and making up the numbers and every one new Justin
Wills was going to win ,former world champion and he understands the
rules.
Could flying is permitted and I know Justin cloud flys because I watched
him
disappear above .Next day while grid squatting I made a point of looking at

Justin's panel ,no horizon but 2 turn and slip.
For the many non Brits Enterprise was set up 30 years or so ago as an
alternative to circuit racing ,the idea being to get as much out of the day
as is
possible and the following day Justin and the day winner do an extensive
debrief explaining the desitions they made both routing and met so we can
all
learn and make better desitions .I recommend looking at there web site and

you will be able to read the ethos more succinctly

I hate this spell checker.
