Gin Gliders and the environment
Protection of the environment, safety and quality are the three basic values of Gin Gliders and
these have implications on everything we do. We also believe that our customers share our
environmentalawareness.
Respect for nature and the environment
Youcan easily play apart in protection ofthe environment bypractising our sportin such a way
that there is no damage to nature and the areas in which we fly. Keep to marked trails, take
your rubbish away with you, refrain from making unnecessary noise and respect the sensitive
biologicalequilibrium of nature. Consideration for nature is required even at thelaunchsite!
Paraglidingis,ofcourse,an outdoor sport – protect and preserve our planet’sresources.
Environmentally-friendly recycling
Gin Gliders gives consideration to the entire life cycle of its paragliders, the last stage of which
is recycling in an environmentally-friendly manner. The synthetic materials used in a paraglider
must be disposed of properly. If you are not able to arrange appropriate disposal, Gin Gliders
will be happy to recycle the paraglider for you. Send the glider with a short note to this effect
totheaddressgivenintheAppendix.

2. Safety
WARNING The safety advices and instructions contained in this Manual must be followed in all
circumstances. Failure to do so shall render invalid the certification and/or result in
lossofinsurancecover,andcould lead to serious injuriesorevendeath.
Safety advice
Paragliding demand a high level of individual responsibility. Prudence and risk-awareness are
basic requirements for the safe practice of the sport, for the very reason that it is so easy to
learn and practically anyone can do so. Carelessness and overestimating one’s own abilities can
quickly lead to critical situations. A reliable assessment of conditions for flying is particularly
important. Paragliders are not designed to be flown in turbulent weather. Most serious
accidentswithparagliders are caused by pilotsmisjudging the weatherforflying.
In Germany, paragliders are subject to the guidelines for air sports equipment and must not
under any circumstances be flown without a valid certification. Independent experimentation is
strictly prohibited. This Manual does not replace the need to attend training at a paragliding
school.
The Manual must be passed on to any new owner if the paraglider is sold. It is part of the
certificationand belongs with theparaglider.
Observetheotherspecificsafetyadviceinthevarious sectionsofthisManual.
Safety notices
Safety notices are issued when defects arise during use of a paraglider which could possibly
also affect other gliders of the same model. The notices contain instructions on how the
affectedgliderscanbeinspected for possible faults and the steps required to rectify them.
Gin Gliders publishes on its website any technical safety notices and airworthiness instructions
which are issued in respect of GIN products. The paraglider owner is responsible for carrying
outtheaction required by the safetynotice.
Safety notices are issued by the certification agencies and also published on the relevant
websites. You should therefore visit on a regular basis the safety pages of the certification
agencies and keep up-to-date with new safety notices which cover any products relating to
paragliding.
