I suspect that the original owner's manual is written in German and
that the word "spoilers" is not mentioned. I don't have my
Schleicher manual here but I think they call them Klappen. Not being
picky for the sake of it, but pointing out that "spoiler" was probably
the word chosen by the translator not necessarily by the manufacturer.
