perhaps in combination with pumping
action through the brake lines.
If neither of these approaches work then
the experts may decide to try either a full
stall or a brief spin on the cravatted side
–
please note that these measures should
ONLY be practised during an SIV training
over water.
WARNING! Should the pilot
be unable to control the
rotation it is normally best to
deploy
the reserve
parachute immediately.
Uncontrolled and cravatted
spiral dives are among the most
dangerous canopy configurations in
paragliding
Full frontal collapse
A negative angle of attack occurring
through turbulence or from simultaneously
pulling down both A-risers results in a full
frontal collapse of the leading edge of the
canopy. The UP Makalu Light will normally
reinflate quickly on its own, but can be
assisted through the application of a light
double-sided symmetrical brake input.
The stalls
When a paraglider flies through the air, a
laminar and a turbulent airflow forms
around the surface of the wing. When the
laminar airflow along the top surface is
interrupted,
dangerous flight
configurations follow
– we say that the
wing stalls. This is most often the
consequence of attempting to fly with too
high angle of attack.
In more detail we differ between three
different forms of stall.
BEWARE! Spin and
full stall are both
dangerous and
somewhat
unpredictable
manoeuvres. Do not
stall or spin your paraglider on
purpose. However it is very important
to learn how to recognize the
symptoms of a glider about to stall or
spin so that you can take correct
action to avoid it happening.
Deep Stall
The UP Makalu Light has no inherent
tendency towards deep stall. It will
recover from a deep stall brought
about by over-braking, by pulling on
the rear risers, or by releasing the B-
risers too slowly after a B-stall, on its
own without any pilot input as soon as
the brakes or the risers are released.
Should you however find yourself in a
deep stall (as described above, this
could happen through flying too light
on the wing and pulling big ears) the
situation
can be rectified by
simultaneously pushing both A-risers
forward until the glider resumes normal
flight. Avoid applying brake to one side
if you think that you are in a deep stall
as this could lead to a spin.
Always remember that practising
manoeuvres where you fly close to
minimum airspeed must only be
carried
out under professional
supervision and with plenty of altitude.
Full stall
Wilfully induced full stalls remain the
realm of the true experts of our sport.
The full stall is when there is no more
laminar airflow along the surface of the
canopy, and the wing has gone from
