Executing a 180-degree turn
The second method is to make a wide 180-degree turn back
into the thermal.
Flying the Core of a Thermal
Once in the thermal, you will need to try to stay in the center of
the lift. Slow down by increasing the up elevator "trim" until the
park glider is just above stall (minimum sink) speed. Make easy
banking turns to find the area of highest lift (thermal core). When
you have found the core of lift, tighten the turns to stay within the
core of highest lift.
As you gain experience, you will find it easier to locate thermals
and track their progress.
