Page 8: Environmentally-Friendly Recycling
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 to the address given in the appendix. -
Page 9: Safety Advice
Gin Gliders publishes on its website any technical safety notices which are issued in respect of GIN products. The paraglider owner is responsible for carrying out the action required by the safety notice. -
Page 10: Operating Limitations
With the chest strap in a more open position, feedback from the glider is increased but stability is decreased. GIN gliders are developed with GIN harnesses, which have an attachment point of approximately 40-48 cm (depending on size and model). EN/LTF as well as CCC certification test flights are carried out with the horizontal distance between the harness attachment points (measured between connector centrelines) set depending on the total weight in flight as follows:... -
Page 11: Reclined Harnesses
If you have any questions or doubts regarding the use of your harness with the Boomerang 12, please contact a GIN dealer or Gin Gliders directly. Reclined harnesses are generally completely enclosed and often have a very low main attachment point. -
Page 12: First Flight
Boomerang 12 user manual _____________________________________________________________________________________________________________________________________ Your instructor, dealer or a specialist must test-fly and inspect the paraglider before your first flight. The test-flight must be recorded on the paraglider information label. Any changes or improper repairs to this paraglider shall render invalid the certification and warranty. Carry out your first flights only during stable weather, and in a familiar area or on a training slope. -

When the glider is overhead, brake it gently if necessary, turn around and launch. If the wind is very strong, it is recommended to make a few steps toward the wing when inflating. This method of inflation makes it easier for the pilot to control the rising of the canopy and is therefore recommended in strong winds. -

Gin Gliders offers a safe, lightweight and easy tow release system, “Towing bridle”. It attaches to the main carabiner and engages the speed system to enhance takeoff safety and climb performance. It is a two piece tow bridle for use with front mount reserves –... -

Use this speed for thermalling and ridge soaring. Stall speed is approached by bringing your hands towards your hips. Notice the decreased wind noise and a significant increase in brake pressure. Once you have become accustomed to flying the Boomerang 12, you can practice using the speed system, which allows improved glide in headwinds and greater penetration in strong winds. -

Release the brake promptly as soon as normal pressure is resumed. If you miss the above timing and get a collapse, be sure to first raise your hands and release the brakes before considering any other corrective actions. -
Page 19: Rapid Descent Techniques
Boomerang 12 user manual _____________________________________________________________________________________________________________________________________ Rapid descent techniques Many flying situations call for a very rapid descent to avoid a dangerous situation, e.g. the up current from a cumulus cloud, an approaching cold front or a storm front. Rapid descent methods should all be practised in calm conditions and at sufficient altitude so that a pilot is then able to employ them effectively if extreme conditions arise. -

Page 22: Dangerous Situations
Boomerang 12 user manual _____________________________________________________________________________________________________________________________________ Dangerous situations and extreme flying Dangerous situations Pilot error, extreme wind conditions or turbulence which goes unnoticed by the pilot for too long may leave the wing in an unusual flying position, requiring special reaction and skills on the part of the pilot. -
Page 23: Canopy Collapses
Boomerang 12 user manual _____________________________________________________________________________________________________________________________________ Canopy Collapses Asymmetric collapses are caused by the stagnation point moving to the trailing edge of the glider. A negative angle of attack makes part of the canopy collapse and tuck under, and the glider may plunge down, turn away or spin. -
Page 24: Symmetric Collapses (Front Stall)
Boomerang 12 user manual _____________________________________________________________________________________________________________________________________ A negative angle of attack can also cause part or all of the leading edge of the glider to collapse. Symmetric (frontal) collapses will normally re-open without pilot input. The paraglider will pitch forward and then regain speed. Assist this process if necessary with a symmetric application of the brakes. -
Page 25: Full Stall (Dynamic Stall)
Boomerang 12 user manual _____________________________________________________________________________________________________________________________________ If you have a speed system, you can also use it to accelerate, so that the glider goes into a normal flying position from the deep stall. After you have landed, the glider and the length of the lines must be checked. -

Page 29: Care
Boomerang 12 user manual _____________________________________________________________________________________________________________________________________ The Boomerang 12 should not be exposed to extreme heat (e.g. in the boot of the car during summer). The heat may cause any moisture present to be pressed through the fabric, thereby damaging the coating. High temperatures accelerate the process of hydrolysis, particularly when combined with moisture, which damages fibres and coating. -
Page 30: Rigid Construction
The plastic rods on the Boomerang 12 can all be replaced through small pockets. If you notice that a plastic rod has been damaged or misshapen because of incorrect use, this can be replaced by Gin Gliders or a Gin Gliders authorised workshop. -
Page 31: Maintenance
_____________________________________________________________________________________________________________________________________ Maintenance GIN gliders have an exact identification on the underside of the wingtip or on the centre rib, which is obligatory for all paragliders. The information required is set out in the airworthiness requirements. It is helpful to provide the type designation of the paraglider if you are contacting your Gin Gliders dealer with any queries or ordering replacement parts or accessories, to ensure accurate identification. -
Page 32: Validity Of Inspection
If the lines are more than 2 cm out of tolerance they should be replaced. If the lines are less than 2 cm out of tolerance they can be re-trimmed either by taking (or releasing) loops on the Maillons or by adding an extended Maillon. Contact your dealer or Gin Gliders for details of how to retrim your glider. Page 32... -
Page 33: Repairs
Allowed loops on Maillons Repairs All repairs and servicing should be carried out by a Gin Gliders authorised workshop or directly by Gin Gliders. Gin Gliders workshops have trained staff, original Gin Gliders parts and the necessary know-how, all of which will ensure top quality. -
