Wet glider

There's a risk of parachutal stall. Parachutal

stall is often the result of a combination of

factors. The water adds to the weight of the

glider. The additional weight causes a hig-

her angle of attack, putting the glider closer

to the stall. Then again, water drops on the

wing surface disturb the laminar airflow ne-

ar the front of the wing, significantly redu-

cing the maximum lift coefficient available.

In order to guard against the risk of para-

chutal stall with a wet wing the glider

should braked as little as possible and big

ears should not be used under any

circumstances.

if the glider was still to go into parachutal

stall recovery should be achieved by use of

the accelerate system (speedbar) only.
