higher - not a swell option on low-wing gliders in
strong crosswinds.)

the other (forward slip) is used to increase the angle
of descent...

.. the ground track is aligned on runway heading,
while the glider's longitudinal axis is decidedly off-kilter.
(Useful in some gliders to further steepen a full-spoiler
approach to a short field or deal with spoiler failure.)
Too much speed and a delayed recovery, however, can
leave you with a glider cum lawn dart.


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?
