Full Stall
PAY ATTENTION_
The forces that occur on a tandem paraglider of this size during the
execution of a full stall are enormously high! To start a full stall, both brakes are fully pulled
through. Depending on the length of the pilot’s arm, it may be necessary to wrap the brake
lines. The Xduo does not empty completely and therefore does not form a stall rosette. The
effort required to keep the Xduo in the Full stall is very high. The canopy should be stabilized
before exiting the full stall. To release, both brakes are released slowly and symmetrically
without collapsing. With correct symmetrical discharge, the canopy shoots only moderately
forward without folding. An asymmetrical collapse is to be avoided. The resulting dynamic
forces and the reactions of the canopy during the discharge are very strong and the paraglider
can fold.

Collapse
Although the Xduo has a very high aerodynamic stability, more turbulence can, as with all
paragliders, cause the canopy to fold. This is usually not critical and self-reopening is quick
and reliable. Reopening can be assisted by vigorously braking or pumping the affected side,
while counter-steering on the open side. In case of large-scale collapse, the countermeasure
has to be precise in order not to completely tear off the flow on the canopy and to get into
the full stall.

Rapid descent
Should a fast descent be necessary due to special weather conditions such as thunderstorms,
a weather front, extreme winds or other dangers and hazardous situations occur, the following
options are available:
PAY ATTENTION_
Under no circumstances may the following manoeuvres be initiated
without the passenger being prepared accordingly!
9.1
„Big Ears“
On both sides, the outer A-risers of the split A-riser are folded downwards (see note), causing
the outer wings to fold. You keep the brake handles together with the folded outer A-risers
in your hand. The glider remains fully controllable by one-sided braking and weight shifting
and steers straight ahead with increased descent speed (3-4 m / sec, depending on the
number of folded-in cells). If you let go of the outer A riser straps, the folded-in cells open
with appropriate load by itself. Should this not be the case, the unfolding is to be initiated by
gently braking.
