  • Page 13 Further details concerning measurements (incl. line data) of the U-TURN INFINITY are posted in the "Typenkennblat" or in the "Luftsportgerätekennblatt §4 Luftverkehrszulassungsordnung" (see appendix). Possible technical changes are published in the according appendixes to this manual. Every change to the con- struction, exceeding the approved adjustments is a potential danger to your life and results in deletion of the official approval.

They have a high tear strength and are unlikely to bend. This stretch resi- stance denies changes in flight characteristics caused by diffe- rent stretching after a short time of usage.

  • Page 16: Suitable Harness

    Suitable Harness All officially approved harnessystems with mounting about the breast height are suitable for the INFINITY (they have to be DHV- rated GH). The lower the mounting, the better is the the steering by shifting of the bodyweight. The positioning of the mounting also changes the relative brake- distance.

  • Page 18: Field Of Operation

    Operation This instruction manual only pays attention to those points of fly- ing technique which are important for the INFINITY. It is not me- ant to substitute a basic flying education in an approved flying school! If a flying education and the appropriate experience is missing, paragliding is dangerous to life.

  • Page 19: Pre-Flight Check

    A careful preflight-check is absolutely mandatory. Double-check everthing when you don´t fly yourself and make sure the person flying your INFINITY does the same. Also ensure that the pilot fly- ing your INFINITY, knows its operational limits and has the re- quired license.

  • Page 20: Takeoff

    Takeoff Hold on to the A-risers and the brakegrips. Recheck the glider on- ce more visually. Take the U-Turn sign in the middle of the cano- py as device to get a centered takeoff run into the wind. Rise the canopy with a firm, steady and even pull. Reach forward with your arms to prolong the A-lines.

  • Page 21: Thermals And Turbulences

    Accelerated flight however is adviseable when flying thru a downdraft zone. The INFINITY is very stable overall, never the less is active flying a big flight safety factor. Collapsing and deforming of the canopy can be avoided by active flying (as above mentioned) in turbulent air.

  • Page 22: Landing

    Landing Start your landing preperation at sufficient altitude. Due to its excellent flaring characteristics, the INFINITY is very easy to land. Glide in fairly normal to a straight-in final against the wind and get up in the harness early enough. According to the wind, the brakes have to be pulled firmly and dynamically, about one me- ter above ground, beyond the stalling point.

  • Page 24: Wingover

    Advanced Handling Even with its high stability and good flight characteristics it is possible that the INFINITY gets into an extreme flight condition due to pilot mistakes or turbulent air. To be prepared for such si- tuations and able to handle them in a calm and superior manner it is best to take part in a flight safety course.

  • Page 25: Frontstall

    Stall The INFINITY is not stall sensitive. If in a stall, casused 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.

  • Page 26: Emergency Piloting

    Emergency Piloting In any situation where normal steering with the brakelines is not possible, the INFINITY can be steered with the back risers easily. Negative Turn / Spin To enter a spin the pilot has to fully and quickly pull one of the brakelines when he is near the stallpoint.
  • Page 27 To avoid them, or how to handle the situation when it happened, some tips or tricks from U-Turn test- and competition pilot Ernst Strobl: The best way to avoid collapses upfront is the right choice of the paraglider.
  • Page 28 Should a collaps occur close to the ground don´t always try to prevent a turn away. There is a danger when the braking on the open side is to strong, to lose the airflow on this side and stall the glider. Rather use the turn away motion to try to open the collapsed side.

  • Page 30: Spiral Dive

    Spiral Dive Like a normal turn, it is very easy to get the INFINITY into a spiral dive. The spiral dive gets you a descent rate up to 20 m/s. To be settled for the real thing, practise it in optimum conditions. The diving spiral gets the pilot down faster than other techniques and is therefore best suited for an emergency descent.

  • Page 31: B-Stall

    You have to release the B-risers simultaneously and expeditious. The INFINITY has no tendency to stall when exiting a B-stall. During a B-stall you drift away with the wind further than during a spiral dive.

  • Page 32: Maintenance And Repairs

    Because U-Turn only uses high quality materials your INFINITY will be airworthy for many years if you take good care. The aging of your INFINITY depends on the total flying time, the conditions you fly in, the amount of UV radiation it is exposed to and the in- tensity and quality of care.

  • Page 33: Safety Advices And Liability

    After two years or 300 flighthours, whichever occurs first, your INFINITY has to be inspected by the manufacturer, in case of extreme use we are glad to do that earlier. Only you know about the conditon of your glider.
