Flying with a wet paraglider

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 higher

angle of attack, putting the glider closer

to the stall. Then again, water drops on the

wing surface disturb the laminar airflow near

the front of the wing, significantly reducing

the maximum lift coefficient available.

In order to guard against the risk of parachu-

tal stall with a wet wing the glider should

braked as little as possible and big ears

should not be used under any circumstance.

If the glider still goes into parachutal stall

recovery should be achieved by use of the

accelerate system (speedbar) only.
