it is important to stabilize the stalled wing.
This is done by releasing the brakes
slowly until the entire wing is almost
completely re-inflated. In this phase the
wing will be pitching somewhat over the
cross axis. The pilot waits until the wing is
in front of him and releases the remaining
part of the brake travel. When timed
correctly the wing will then resume level
flight by surging slightly forward whilst
accelerating to normal trim speed.
However you must be prepared to
dampen the surge and deal with any
subsequent collapses occurring because
the wing surges too far or doesn’t come
out of the full stall completely
symmetrically.
Test pilots also carry out tests where they
release one brake before the other while
in full stall. This manoeuvre only serves to
test the wings behaviour and should not
be flown purposely as this is a situation
where all paragliders react very
dynamically. It is often followed by very
large, dynamic asymmetric collapses that
must be dealt with correctly to avoid
dangerous situations.

The negative spin occurs when one side
of the wing is stalled whilst the other is still
flying. This can happen when, if flying very
slowly, one brake is pulled quickly to
below the seat. When the glider starts to
spin, it will turn quickly around the vertical
axis, with the stalled side flying
backwards. To recover from a spin, simply
release the brake on the stalled side. The
glider will immediately speed up and, most
likely, suffer an asymmetric collapse.
Recover as described above.
If you suspect that a spin is imminent then
immediately release the inside brake. The
glider will accelerate smoothly and resume
normal flight with little altitude loss.

Wingovers are induced by flying
alternating turns; each time letting the
pendulum effect increase the bank
angle.

The UP Trango XC is a
agile glider, and it is quite easy
to get to an excessively high
angle of bank in just a few
turns. Practice wingovers
gently at first, as there is a
chance of quite large
collapses at high bank angles.
Also notice that a wingover flown with
more than 90 degrees bank angle is
classified as illegal aerobatics in some
countries!

If for some reason the UP Trango XC
cannot be controlled with the brakes,
for example if the brake handle has
come off the main brake line, it can be
steered and landed with the rear
risers. Be aware that, when rear riser
steering, the glider is a great deal
more responsive to pilot input, and the
stall happens very suddenly.

There are two reasons why flying with
a wet wing increases the risk of deep
stalling:
First reason is that the canopy cloth
may absorb water, making it much
heavier and moving the centre of
gravity around in unpredictable ways,
increasing the risk of a stall/deep stall.
The more water a wing can absorb the
higher the risk, which means that older
