Spin (Or Negative Spin) - Nova ARGON Betriebshandbuch

An "asymmetric" recovery (one control released faster than the other)
from a full stall can cause a big dynamic collapse.
IF A FULL STALL IS RELEASED TOO EARLY, TOO SLOW OR TOO
FAST, OR OTHERWISE INCORRECTLY, THE CANOPY CAN SURGE
The danger of overcorrecting and overreacting exists during all extreme
flight maneuvers;
thus, any corrective action must be gentle and steady and done with
feel!

Spin (or negative spin):

During a spin the canopy turns relatively fast around the centre section
of the canopy while the inner wing flies backwards. (hence the term
negative)
There are two usual reasons for an unintentional spin:
- one brake line is being pulled down too far and too fast (e.g. when
inducing a spiral dive)
- when flying at low speed one side is being braked too hard (e.g. when
thermalling).
To recover from an unintentional spin, the pulled down brake line should
be immediately released as soon as a spin is suspected. The canopy will
accelerate and return to its normal straight and stable flying position,
without losing too much height.
In case the spin is allowed to develop for some time, the NOVA ARGON
surges far forward on one side and a dynamic asymmetric collapse or a
line over can occur. If so, brake gently to stop canopy surging and
correct any collapse: See "collapses".
Too tight cross bracing increases the probability of a spin with most
paragliders!
NEVER DO AN INTENTIONAL SPIN OVER LAND OR IF YOU DON'T
EXTREMELY FAR FORWARD.
HAVE SUFFICIENT EXPERIENCE!
