CHECKS ON THE NEW PARAGLIDER
Before delivery, as well as during production, each paraglider goes through a strict
visual inspection. Additionally we recommend that you to check your new glider in
accordance with the following points. We recommend that you make this check after
flying extreme manoeuvres or after tree landings or similar.
•
Inspection of the canopy for tears or damage, especially the seams which join the
ribs to the upper and lower surfaces, but also the area of the attachment tapes and
brake-line connections.
•
Inspection of the lines for damage to the stitches. The line lengths must be checked
after 50 hours flying time and whenever the flight behaviour of the glider changes.
•
Inspection of attachment tapes for damage to the stitches. It is also important to
check the attachment tapes and brake-lines for tangles.
•
Inspection of the risers for faultless condition. Rapid links must be secured.
With even slight damage the glider loses its airworthiness
ADJUSTING BRAKE LINES
The brake lines lead from the trailing edge of the canopy to the main brake lines which
then run through pulleys on the D-risers to the brake handles. A mark on the main brake
line indicates the position of the brake handle.
The glider is delivered with a standard set-up and its speed can reach 36 - 38 km/h
depending on the weight of the pilot. The brake-lines should always be adjusted so that
the first brake-lines just come under tension when the brake handles have been pulled
5 - 10 cm. The test results relate to this brake-line adjustment. This adjustment, on the
one hand, allows sufficient brake to be applied during extreme flying situations and
when landing, while on the other hand, it ensures that the canopy is not permanently
braked (especially when fully accelerated). This trim should not be altered. In extreme
situations any other settings may lead to the glider reacting differently to versions which
have been tested.
NOTE!! If in doubt about the brake-line adjustment, it is preferable to leave them too
long, as any necessary shortening can easily be achieved by wrapping them round your
hand.
