Flying with a wet Glider
If you fly a wet paraglider the risk of para-
chutal stall is heightened. Parachutal stall
is often the result of a combination of fac-
tors. Water increases the weight of a wet
canopy. More weight results in an in-
creased angle of attack, which brings the
glider closer to the parachutal stall
boun dary.
In addition, water drops on the fabric have
a bad effect on the laminar flow over the
leading edge, and this significantly reduc-
es the maximum achievable lift coefficient.

To minimise the risk of parachutal stall a
wet glider should be braked as little as
possible, and big ears never used. But, if
the wing still goes into parachutal stall,
recovery should be achieved by accelerat-
ing using the speed system only.
