1 THE PRODUCT_
1.1 GRAVITY X pressure_ simply dynamic
Xpressure - The acro wing with supreme handling! The glider’s success story is based on a
balanced canopy-harmony, offering the perfect mix between mistake-forgiving dynamics as
well as precise, spot-on handling. We achieved a clear improvement in terms of dynamics as
well as the handling, without making the glider more aggressive. Qualities which make the
Xpressure equally suitable for acro beginners, hobby acro pilots and professionals. We are
proud that we received superb feedback during the world cup race season, enabling us to
create this powerful, enduring wing while applying latest materials and technologies to
insure pilot security. The concept and planning of the Xpressure was designed to make the
usability, manoeuvrability homogenous. This wing is performing very subtle and well under
extreme conditions with optimal state-of-the-art tear-proof materials.

Our acro wing with the invincible and matchless handling!
Let us tell you about the success story of the Xpressure which is based on a balanced
canopy-harmony, offering the impeccable mix out of mistake-forgiving dynamic and precise
handling. When designing the Xpressure we were able to achieve a clear improvement in
terms of dynamics as well as the handling, without making the glider more aggressive

already during R & D phase. What we like best with the Xpressure achievements is that it
reaches a broad range of pilots as its characteristics combine crisp dynamics with easy
handling. The wing is therefore suitable for hobby acro pilots, to acro beginners as well as
professionals. A challenge during the concepting and designing period was that we had
managed to make and outstanding acro glider but wanted to enhance the outstanding
features further with adding sweet-temperedness and fault forgiving features to the
dynamic wing at the same time. We are truly proud to present our achievements with the
most balanced acro wing for now, GRAVITY’s Xpressure.
Illustration 02_ GRAVITY Xpressure
Much value was also placed upon durability of the Xpressure as well as maintaining the
excellent flying characteristics under extreme loads. Therefore the wing is supplied pre-
trimmed. When manufacturing the Xpressure we purely use the purposely developed PX40
material. The well-known material has an innovative coating which provides enhanced long-
term results and improved tear resistance. PX40 is currently the strongest fabric used to
build a wing. When it comes to the processing and manufacturing, we do our utmost with
strong emphasis on durability and shape accuracy.
The turning in the connections of all negative manoeuvres is very homogeneous with the
Xpressure which reduces the twist-tendency and offers more safety, especially for acro
beginners.

1.2 Pilot Profile
The Xpressure addresses ambitious acro pilots looking for a highly developed dynamic wing
with direct and sportive handling. Acro newbies as well as professionals have to be in very
good physical and mental condition. Dynamic flying demands especially high concentration
from the pilot while exposing them to extreme physical stress due to the great centrifugal
forces. We ask you to always pursue aviation with the proper cautiousness and respect. This
includes profound, extensive flight preparation as well as the examination of meteorological
conditions and the proper evaluation of the weather situation. Act defensively and proactive
at all times! Remember that increasing fun by reducing risks! An important point during the
countless test flights of the glider through GRAVITY Acro Test pilots was the optimization
of the brake pressure. Manoeuvres like Corkscrew or McTwist can be done without winding
that way.

1.3 Use
The Xpressure was built for single-seat use only. The Xpressure is a light air sports device,
with an unladen weight of less than 120 kg in the paraglider division. The training-ready
Xpressure glider is ideal for a wide range of acro pilots; from newbies, to achievers and
experts.
All sizes are type tested and classified according to shock and loadtest.
1.4 Signboard
The essential and relevant product data is positioned on each product by default and in
accordance to the admission office. In the case of the entire GRAVITY paraglider range
these are visibly placed are the centre of the canopy.
