Cravats; Care And Maintenance - Nova IBEX-4 Handbuch

_62
During a parachutal stall close to the ground it is important to judge
whether there is sufficient height for the wing to recover from this
oscillation. In this case, a (hard) landing in parachutal stall is preferable
to landing while the wing is still in pitching forwards or backwards.

Cravats

If a part of the wing is so tangled in the lines that it cannot free itself
(possibly after a collapse), it is referred to as a cravat. This occurrence
cannot be discounted on any model of paraglider.
In the case of a cravat, we recommend the following:
1. Brake on the opposite side:
ric collapse, the wing will try to turn in the direction of the cravatted
side. If the pilot does not use the opposite brake (on the open side),
then the rotation of the wing can quickly turn into a locked-in spiral
dive which either requires great effort or in some cases it is actually
impossible to exit. It is essential to prevent this rotation.
2. Open the cravat by pumping the brake:
on the tangled side may release the cravat. A timid pull of the brake
rarely works.
3. Pull the stabilo line:
the stabilo line may work. The stabilo line is the outermost line on
the B-riser and is green in colour.
4. Collapse the cravatted side:
the A-risers may be effective.
5. Full stall: A pilot who has mastered the full stall manoeuvre has an

effective method of releasing a cravat.

Make a habit of mentally rehearsing throwing your parachute by, for
example, practising putting your hand on the parachute handle during
flight. This is useful preparation should the worst happen.
Many clubs or schools offer an opportunity to practise throwing your
reserve parachute on a zip line. The most effective practise is obvi-
ously actually throwing the parachute during an SIV/pilotage training.

Care and maintenance

With care and careful handling, a paraglider can remain in a technically
perfect state for many years – even if used intensively. An exception to
this are lightweight paragliders which degrade more rapidly with inten-
sive use. We recommend the following:
• The wing should not be unnecessarily exposed to UV radiation, for
example if left for a long time in direct sunlight on take-off or landing.
• When folding the glider it is advisable not to bend the rods in the
leading edge.
• If the wing is wet or even only damp when being packed, it should be
fully dried as soon as possible. Storing the glider damp can lead to
permanent damage.
• When landing or groundhandling, try to avoid hitting the leading edge
hard on the ground. This can lead to damage.
• The lines should be protected from dirt and sharp rocks. Never step
on the lines if on stony ground.
• Over a period of time, dampness in combination with dirt can lead to
lines shrinking and the glider going out of trim.
• Salt water (including sweat) and sand damage lines and sail cloth.
This has a negative effect on their durability and strength.
• Do not drag your wing across the ground – particularly not the rods
in the leading edge.
