Rapid Descents - Nova XYON Betriebshandbuch

39
Deep stall :
The NOVA XYON generally does not remain in deep stall, and is self
recovering, when releasing the brakes or rear risers which have caused
it.
In case the recovery from a B-stall was not impulsive enough and the
canopy remains in a deep stall, it is sufficient to gently pull down both A-
risers to reduce the angle of attack and re-attach airflow to the canopy.
Emergency steering :
In case it is impossible to control the NOVA XYON with the control lines
the outer C-lines, C-risers or the stabiliser lines may be used to steer
and land the canopy.

Rapid Descents:

Spiral dive :
Spiral dives as explained previously have a rapid descent rate, however,
the very high G-forces make it difficult to sustain a spiral dive for long
and it can place large G-forces on the pilot and glider. Never do these in
turbulence or at too high bank angles.
NEVER DO BIG EARS IN A SPIRAL. DHV-tests have proven that loads
can be developed higher than those used in certification tests, which
could result in structural failure of the glider, as less lines are taking
these high loads.
In case of strong winds the pilot may drift off course.
Big ears :
The outer cells of the wing tips may be deflated by pulling down one to
two of the outer A-lines simultaneously by approximately 50 cm.
NOTE : if two lines are pulled, only one A line is remaining.
Keep hold of the control handles together with the A-lines.
The canopy remains completely controllable through one sided braking
or weight shift. It maintains straight flight but with an increased sink rate
(up to approx. 5 m/sec).
