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

(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?
