I see. So the two ideas are aerodynamically the same, but what you call
a sideslip is used for cross wind landings and a forward slip for
steepening the glidepath?





In the US, the term "sidelslip" is shorthand for a forward slip to
landing.

A forward slip can be properly done with the low wing into the wind or
not. A sideslip (forward slip to landing), must obviously be done
with the low wing into the wind or you will be unable to align the
longitudinal axis of the glider with the ground track.
