Flying outside the
normal flight
envelope
Behaviour in extreme
situations
The UP Summit XC² is designed to be
very aerodynamically stable. However as
with all paragliders extreme turbulence or
piloting error may induce unwanted
behaviour from the canopy. To ensure that
you are able to handle these situations
correctly we strongly recommend that you
attend a safety-training (SIV) clinic, where
you can learn to master your wing outside
the normal flying envelope under
professional guidance.
Safety training manoeuvres should only
be practiced in calm air with sufficient
altitude, and under the instruction of
qualified instructors. We would like to use
this occasion to once again remind you to
never fly without a reserve parachute!
The manoeuvres and possible flight
configurations described in the following
may occur following a conscious effort on
the part of the pilot, through turbulence or
through pilot input error. Any pilot flying in
turbulent air or making piloting mistakes
may end up experiencing these flight
configurations and therefore find
themselves in danger, particularly if they
are not adequately trained to master them.
WARNING! Mistakes during the
execution of the following
manoeuvres may seriously
compromise the safety of
pilot.
Collapsing the
paraglider
Asymmetric collapse
The UP Summit XC² belongs to the
new generation of paragliders that, as
well as having very good performance,
also exhibit a high degree of stability.
Wing tip collapses can almost always
be prevented through active flying.
Once an asymmetric collapse has
occurred the pilot aims to maintain
flying direction through weightshift and
careful application of brake input on
the open side.
If the open side is braked too much it
may stall, and the wing will enter a
spin
– this is the classical recipe for
cascading events (see the Spin
chapter).
In rare instances a wingtip may catch
in the lines during asymmetric
collapses (see Cravattes here below).
Cravatte
Our test pilots have found absolutely
NO tendency towards cravatting in all
the test flights the Summit XC² has
been subjected to. But under
extraordinary circumstances any
paraglider may cravatte, and if this
happens the pilot should know how to
deal with the situation.
The first step is to STOP any rotation,
or, if this is not possible, to slow down
the rotation as much as possible
– a
cravatted wing that is left to its own
devices may very quickly enter into a
spiral dive of such vehemence that the
pilot cannot stop the rotation any more.
Once the rotation is under control the
pilot attempts to free the cravatte by
pulling on the (purple) stabilo line,
