Maintanence And Storage - Gradient BRIGHT III User Manual

5.3.5 Negative spin
- initiation: Slow down by braking to nearly minimum speed. Then pull a brake
on one side all the way down while simultaneously releasing the brake on the
other side. Because the stalled side falls back, the canopy suffers air flow
separation over one half of the wing which results in a spin and a rapid loss of
altitude.
- recovery: Under normal circumstances BRIGHT III s capable of recovering
from a negative spin automatically when brakes are released.
Caution: In general when there is a very fast or a long-lasting rotation and when
the brakes are released too quickly, the canopy may shoot in front of the pilot
followed by a massive asymmetrical collapse.
Warning: In all regimes where the air flow is separated there is always a rapid
increase in sink rate and therefore a substantial loss of altitude.
And remember: A wrong manoeuvre at the wrong time may
change a fairly easy situation into a dangerous problem and
furthermore you are exposing your glider to forces which may
damage it. So practise your pilot abilities for these special
flight regimes only under the supervision of your instructor and
with a reserve parachute!

6. MAINTANENCE AND STORAGE

If you handle your glider with care and store it in a suitable place it can last
you a very long time. On the other hand neglecting maintenance, bad storage
and the use of unsuitable cleaning products can reduce the lifetime of your
glider significantly or may even make a dangerous subject out of it.
You must keep to these rules:
• Choose a suitable area for your launches. Lines caught on roots or rocks lead
to unnecessary strains on the attachment tabs during inflation. Snagging lines
may rip the canopy tissue or damage lines.
• When landing, never let the canopy fall on its leading edge in front of the pilot.
The effect of these forceful collisions and the sudden pressure increase can
