Wet Paraglider

If you fly a wet paraglider the risk of para

chutal stall is heightened. Parachutal stall is

often the result of a combination of factors.

Water increases the weight of a wet cano

py. More weight results in an increased

angle of attack, which brings the glider

closer to the parachutal stall boundary.

In addition, water drops on the fabric have a

bad effect on the laminar flow over the

leading edge, and this significantly reduces

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.
