In flat launch sites you pay attention to the acceleration phase. Large, long and expansive steps with
little brake are ideal here. In steep terrain, on the other hand, you pull gently and apply brake pres
-
sure to stabilize. The glider must not be allowed to over shoot as collapses in the lift-off phase on
steep slopes can become unpleasant. Since take off is very quick in steep terrain, it is a good idea to
have an experienced pilot friend who observes and checks the take-off during the lift-up phase.
In flat terrain take-off may be more impulsive. After inflating and lifting the paraglider, perform a de
-
tailed visual check of the canopy. The running speed is reduced and adapted to the wind situation.
In the steep launch site, the start is initiated with a small impulse and then a clear brake pull.
With an adequate launch impulse/input the
canopy lifts off. The lifting force caused by the
pronounced curvature of the profile at the
leading edge is sufficient to lift a portion of
the wing with its own weight.
As the canopy rises, the effective curved sur
-
face increases and with it the lifting force until
it is strong enough to lift off the entire weight
of the canopy.
Thereby and by the air entering the cell open
-
ings in the canopy’s leading edge the profile
becomes fully inflated. The forward force of
the aerofoil profile accelerates the canopy
forward. In order to stabilize the wing above
the pilot a slight brake pull is used.
