6.2 ACROBATIC FLIGHT
Although the HOOK 4 P was tested by expert acrobatic pilots in extreme
situations, it WAS NOT designed for acrobatic flight manoeuvres. DO
NOT USE THIS GLIDER for aerobatic manoeuvres. We define aerobatic
flight as any form of piloting where the paraglider is placed in attitudes
that are not used in normal flight. To safely learn how to master aerobatic
manoeuvres, instruction must be undertaken at a certified school, under
the guidance of a qualified instructor and in a safe environment.
A complete wing and line inspection should be performed every six
months, including repairs if necessary, to guarantee the integrity of the
equipment. Extreme manoeuvres means you and your wing can be
exposed to centrifugal forces that can reach 4 to 5 G.
7. FOLDING INSTRUCTIONS
The HOOK 4 P has a complex leading and trailing edge manufactured
using a variety of different materials. A correct folding method is very
important to extend the useful life of your paraglider. It should be
concertina-packed, with the leading edge reinforcements flat and the
Nitinol flexible rods stacked up on top of each other. This method will
keep the profile in its original shape and protect the integrity of the wing
over time.
The wing should then be folded in three sections while taking care of not
to bend or twist the SLE. There is no need for compression during the
procedure; doing so may damage the fabric, including the risers and lines.
8. CARE AND MAINTENANCE
8.1 MAINTENANCE
Careful maintenance of your equipment will ensure continued top
performance.
The fabric and the lines should not be washed. If they become dirty,
clean them with a soft damp cloth.
If your wing is wet from contact with salt water, immerse it in fresh water
and dry it away from direct sunlight.
Direct sunlight may damage the wing’s materials and cause premature
aging. After landing, do not leave the wing exposed to the sun. Pack it
properly and stow it away in its backpack.
If flying in a sandy environment, and sand has accumulated inside the
wing, remove it before packing it away.
8.2 STORAGE
It is important for the wing to be correctly folded when stored. Keep it in
the in a cool, dry place away from solvents, fuels, oils and UV rays. Do
not leave the gear inside a car boot, as temperatures can reach up to
60ºC and damage it. Weight should not be laid on top of the equipment.
If the glider is stored with organic material, such as leaves, grass or
insects trapped inside the cells, the chemical reaction can cause
irreparable damage.
8.3 CHECKS AND INSPECTIONS
The HOOK 4 P must be periodically serviced. An inspection must be
scheduled every 100 flying hours or every twenty four months whichever
comes first (EN/LTF normative).
Regular maintenance is the only way to guarantee the HOOK 4 P’s
integrity and keep it functioning as it should, while still conforming to the
certification criteria.
