LOL.. Martin... trying to gather data points for explaining someone's debate
with you?

Rule #1, Listen to Martin..
Rule #2, if in doubt.. Refer to Rule #1

heading of aircraft should not change.. ground track will remain the same

if the instance of stalls.. should not matter.. just depends on how fast he
either gets blown away from or back towards the airport during the stalls..

The aircraft.. once in the "air mass" does not care what a steady state air
mass motion is doing, only the pilot cares about what he needs to do in that
air mass to get to where the pilot wants to go.

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?
