Introduction
U-Turn paragliders are in a class of their own. U-Turn doesn`t compromise on safety, and uses the best
quality components and hallmark ight characteristics. Be happy your are ying a U-Turn glider, as it is
the brand for those who appreciate the dierence.
The laws of physics are well dened. We aspire to achieve to possible within the framework of its laws.
We admit this is ambitious but you will always nd U-Turn at the cutting edge of technology.
As Oscare Wilde once said in this very British understatement: “His taste is very basic; only always the
best is good enough.”The U-Turn team embodies the attitude; “We always want to deliver the best pos-
sible glider.” Nothing more and most certainly nothing less.
U-Turn sta takes notice of its customer wishes, so we appreciate any comments or feedback!
Please feel free to contact your competence center or U-Turn directly for any advice or direction.

With the AIRWOLF, U-Turn has successfully implemented the appreciated best seller concept also in the
DHV/LTF2 wing class: maximum performance and high level security standard. A completely new de-
signed prole combined with the PPNplus system provides secure ying fun – features that are much
valued by the U-Turn pilots.
The U-Turn AIRWOLF is a performance focused cross country wing, providing high resistance against
folding despite the immense snatching of 6.0 and the extreme performance. From the very rst moment
the pilot feels: this wing holds excellent performance reserves and I can rely on it! The performance
more or less results from the genes, because the AIRWOLF is a direct descendant of the top performer
AIR FORCE II. The security feature is ensured by the PPNplus technology of U-Turn: Instead oft he nose
Mylar, synthetic rods reinforce the prole nose not only along the sewings of the cell membranes, but
also directly above the openings. Thus, the inner pressure is retained for a longer time also in extreme
conditions; the prole and the air stream are maintained.
Even if not apparent at rst sight, the real intrinsic values of the wing are the optimized cross ports. They
are required to ensure the quick and smooth re-ination of the canopy, but too many of them might also
be a disadvantage during the ight. With other words: the less cross ports are required to ensure the
optimum relling of the canopy, and the smaller the required cross ports can be dimensioned, the more
stable is the canopy during the ight. The nal success story of the AIRWOLF is, that it has been possible
to reduce the cross ports substantially thanks to the interaction of the prole and the PPNplus system.
Altogether, the AIRWOLF considerably rises above the standard. The overall construction shows its mag-
nitude for example during thermals in/outs: the usual pitching of the wing is denitely lower; the pilot is
not brought into pendulum position. The result is that in thermal active conditions the gliding perform-
ance literally beats up by a mile the other gliders in this category. While other gliders are still oscillating
around, the AIRWOLF gains some meters. Thanks to the new prole, the AIRWOLF is an excellent ther-
mal riser. Specially in weak thermals he hardly can be caught up and can be inclined gently. Its layout
provides lot of fun. In very thermal or very turbulent air, the AIRWOLF is gliding consistently.
General Description AIRWOLF

Page 2
Never y in close distance to high voltage transmission lines, airports and motorways, over humans or
with thunderstorm! - Mortal danger - Otherwise you endanger the life and the body third and/or your
own and act at the same time roughly negligently! The minimum distance to these objects is 50m. To
airports rises distance to 5 km.

Risk assumption
The use of the U-Turn AIRWOLF accommodates certain dangers of body injury or killing of the user of
this product or third. With the AIRWOLF use you agree, all well-known and unknown, to take and accept
probable and improbable injury risks on itself
The dangers connected with practice of this kind of sport can be reduced by the attention of the warning
references of the manual, as well as the care ordered in individual cases. This sports inherent risks can
be reduced to a large part, if one adheres both to the maintenance guidelines, which are listed in this
operating instruction, and by the healthy human understanding.

Especially in rough conditions the AIRWOLF demonstrates its class. The stability of the glider is backed
by the proven and tested Improved Stability Technology (IST) with V-rips and elaborate prole guid-
ance. Thus the high performance is not achieved through a particularly distinctive feature of the glider,
but is based on plenitude of design features and characteristics, which make the AIRWOLF a highly bal-
anced glider – a real racehorse but with no hectic pace and with no air and graces.
The PPNplus system provides further benets: As the material is not sensitive to bending, the prole
nose might retain its form for a glider lifetime, if carefully handled. In many years’time, the AIRWOLF will
still have excellent take-o qualities. If ever a synthetic rod is bent or defective, it can be easily replaced.
Without the former Mylar reinforcements, the weight of the canopy has been noticeably reduced, a fact
which provides advantages for handling and feedback.
Fine-tuning was made amongst others by the test pilots Patrick Berod and Vincent Sprüngli. Therefore,
U-Turn customers can feel condent to purchase an absolutely perfected and well-engineered wing.The
AIRWOLF is made of high quality NCV cloth, Liros lines and is available in attractive colour combinations.
The AIRWOLF is available in ve sizes ranging from XS to XL (Certied for sizes S, M + L).

Security notes
• Excecute manouvers with the U-Turn AIRWOLF only over water.
• Pay attention th the high sink rates in“dynamic ying”.
• be aware of the high G-force occuring in dynamic ight ( 5 G and more).
• Fly the U-Turn AIRWOLF never without a rescue paracute. Preerrable 2 rescues!
• The observance in the respective country valid air law laws and regulations is to be considered.
• The required education, training, knowledge and is mandatory for using the U-Turn AIRWOLF.
• The use of suitable, examined and accessories certied in the respective country (Helmet, harness,
rescue paracute) is mandatory for the AIRWOLF usage.
• Weather conditions got serious inuence to ight security.
• The ysite got direct infuence to ight security.
• Inspect the glider before each start carefuly (canopy, in particular the lines, carbiners, belt buckles,
cloth, speed system etc..
• Make sure the glider is in propper condition and all inspections are done.
• Be aware that a pilot must be physically and mentally able to do the ight

Weather dangers
Informin the weatherforecastand/orlocallyoverupcomingweather conditions.UsetheU-TurnAIRWOLF
only with winds you are able to keep the glider fully under control. Do not use the U-Turn AIRWOLF, if
wind conditions vary strongly. Never use the U-Turn AIRWOLF with approaching thunderstorm. Descend
fast and land immediately with thunderstorm approaching on horizon!
Ignoring one or several security rules
can turn a fun ight into a lethal ight!

Lines and risers
We use DC 60, DC 100, LTC 0080, LTC 0120, LTC 160 TGL200 Liros lines as well as TSL 190, TSL 220, TSL
280 (TSL = Aramid Kern) with a special weaved Dyneema core. They have a high tear strength and
are unlikely to bend. This stretch restistance denies changes in ight characteristics caused by dierent
stretching after a short time of usage. An optimum of safety and strength in relation to drag is achieved
by the use of dierent line diameters.
The whole line system consists of single elements that are sewed and looped on both ends. All suspen-
sion and brake lines are forked in the upper part. The dierent colour of the lines guarantee easy han-
dling and control. All suspension lines are looped seperately in rapidlinks and coected to the risers. The
rapidlinks have collectorclips built in to prevent slipping of the lines.
After the intervall or after 100 igth hours must be check the lines.
Brake line settings
The main brakeline is looped through a reel at the D-riser with a colourmarking where a brakegriphas
to be tied on. The manufacturer setting is 0 travel plus 5 cm. Shortening more then 5 cm is not allowed
and results in a “ brake”condition in ight which is extemely dangerous for takeo, ight and landing.
The basic setting provides sucient braking action at landing and in exteme ight conditions besides a
comfortable armposition in trimmed ight.
Please note that with the height of the harness mounting also the relative brakedistance changes.
When adjusting the setting, both sides have to be symmetrically and a permanent knot has to be used.
Optimum solution is the so called“Spierenstich” knot with its high slide resistance and its little eect on
the lines.
