Here are two simple questions. The glider is an ASK-21
and for both questions the wind conditions are a smooth
steady 25 knots with no wind shear or gradient.

1. The pilot is holding North on his compass and the
glider is trimmed for 43 knots. He has a 90 degree
right cross wind from the East. The pilot then releases
the controls to see what the glider will do.
Do you believe the glider will turn into the wind,
downwind or stay facing North?

2. The pilot next decides to practice stalls upwind and
downwind to find out if they are the same other than
the groundspeed.
Will he or should he notice any difference?
