Noel: the technique I've used is to track heading (as well as airspeed
(if provided), ground speed and both altitudes) and it's easy enough
to use that to tell when a 360 degree turn has been completed (thus
assuming start of a thermal).

If you're using C++, the exercise is a lot easier if you use STL
containers!

Noel,

Sounds like collision warning device predictive path software??

I know nothing about programming but I think that gusts swinging the
tail of a glider is a negligible factor in the context of predicting
the path of a glider from log traces
