Page 7: The Product
THE PRODUCT_ GRAVITY Xduo_ high performance A new era of tandem flight has begun. We managed to take the agile solo handling to the two -seater class with our Xduo for the very first time! High turn propensity while using low control pressure are making this glider a very efficient and fun working tool for every tandem pilot. - Page 8 The Xduo is covering a high weight range for a start weight from 140 kg up to 230 kg for one and two seated flying. Both versions have the LTF/EN B certification. Illustration 02_ GRAVITY Xduo Chief designer Ernst Strobl equips the Xduo with various constructive innovations. The PPN and the shark nose are providing a higher profile fidelity alongside the cell opening.
-
Page 9: Pilot Profile
Working very efficiently in thermal lift and reliably transforms it into height and when in turbulent air, the glider stands solidly with precise feedback and a direct flight feeling. Illustration 03_ GRAVITY Xduo The shark nose is providing high stability and an extended inflow area. We doubled passive safety as it is a priority when flying with passengers. -

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. -
Page 11: Possible Use
E-climbing assistance/ E-ascent aid Due to its unproblematic handling and high trim speed, the GRAVITY Xduo is ideally suited for the e-ascent aid. Towing winches The Xduo has no specifics when it comes to winching. -

The double fisherman’s knot/ spar or pile stitch has proven particularly effective in that since it weakens the lines the least with excellent slip resistance. Illustration 05_ bowline/ double fisherman’s knot USER MANUAL GRAVITY Xduo EN REV.V01 - 2020... -

Never use the screen during approaching thunderstorms or storms or when there is a high probability of thunderstorms or storms 19. -

Page 17: Colours And Design
Colours and Design_ “Never change a winning horse!” One of the unique selling points of the GRAVITY product range is that each glider product is only available in a single lead design and comes without colour variations or special designs. -

EAR-FIX-CLIP. The clamping device is elegantly covered with neoprene and allows the pilot to fix the outer part of the split A lines at any desired position.

- Page 20 Thereby the form of the profile stays intact which ensures clearly better gliding. GRAVITY recommends to keep the trimmer closed during take- off and landing. All extreme flight attitudes (e.g. collapses) are occurring more dynamically at higher speed.
- Page 21 The unbalanced suspension can cause the pilot and passenger to be in an uncomfortable flight position and also makes it difficult to control the glider. Illustration 12_ trimmer spreaderbar USER MANUAL GRAVITY Xduo EN REV.V01 - 2020...

The landing field should be generously sized and the landing site can be obstacle and turbulence free. USER MANUAL GRAVITY Xduo EN REV.V01 - 2020... -
Page 23: Briefing Of The Passenger
Harnesses with an airbag or protector have proven to be effective, as many passengers to not run when landing, but tend to sit down in the grass. USER MANUAL GRAVITY Xduo EN REV.V01 - 2020... -

(except Twistlock). The passenger is in front of or along-side the pilot during all flight phases. Suspensions which allow a position of the passenger behind the pilot are not permitted for reasons of safety! USER MANUAL GRAVITY Xduo EN REV.V01 - 2020... -
Page 25: Pilot/ Passenger Configuration
If the passenger runs too timid, the command “run” should be repeated aloud and the passenger may be encouraged to accelerate by pressure from the pilot. USER MANUAL GRAVITY Xduo EN REV.V01 - 2020... - Page 26 USER MANUAL GRAVITY Xduo EN REV.V01 - 2020...

Extreme Flight Manoeuvres Although the Xduo has a very high level of aerodynamic stability, turbulence or pilot errors can cause the Xduo to reach an extreme flight situation. The most established method of USER MANUAL GRAVITY Xduo EN REV.V01 - 2020... -
Page 29: Wingover
Deep stall The GRAVITY Xduo is not stall sensitive. If in a stall, caused by over-pulling on the brakes, the rear risers or a delayed B-stall exit, the release of the brakes or the rear risers, recovers the stall. Should the stall be caused by an extreme flight condition or configuration (i.e. take-off weight to low), a symmetric forward push on the A-riser or opening the trimmers recovers the stall. -
Page 30: Full Stall
If you let go of the outer A riser straps, the folded-in cells open with appropriate load by itself. Should this not be the case, the unfolding is to be initiated by gently braking. USER MANUAL GRAVITY Xduo EN REV.V01 - 2020... -
Page 31: B-Stall
Emergency piloting/ control If for some reason it is not possible to control the GRAVITY Xduo with the brake lines, it can also be controlled and landed very well with the back risers. Turns can be flown and added with a weight shift, but please pay attention that the glider does not lock in a spiral. -
Page 32: Packing
How quickly your GRAVITY Xduo ages, ultimately depends on how often it is flown, where it is flown, how many UV-hours it accumulates and how carefully and regularly it is cared for. -
Page 33: Recycle
11.2 Recycle GRAVITY uses only safe materials and puts a lot of value into saving resources as well as using non-detrimental materials. Nevertheless, the materials used in a paraglider need proper disposal. Please return worn out gliders to GRAVITY airsports & more GmbH or disassemble the glider into its parts and recycle them accordingly. -
