1. Bi Discovery 3 Thank you for choosing SC Bi Discovery 3 This manual will help you to get maximum information about your glider This 1s information about the design of the Bi Discovery 3 advice how to use it best and how to care for it to ensure it has a long life The manual also includes technical specifications and line plans We hope that the Bi Discovery 3 will give you a lot of wonderful flying hours Bi Discovery 3 is suited for tandem flying Tandem pilot must have at least 50 hours of flying time Bi Discovery 3 is also good for paramotoring N N Warning Paragliding is a high risk activity We strongly recommend to learn paragliding only in certified schools and to choose only the equipment which is correspondent to Your flying skills N Technical data size 38 41 44 scale 1 19 1 233 1 276 wing area sq m 38 15 40 95 43 86 span m 14 23 14 75 15 26 aspect ratio 5 31 area projected sq m 32 98 35 4 37 92 span projected m TL Dal 11 66 12 07 ar projected 3 84 root chord m 3 38 25 3 62 tip chord m 0 6 0 62 0 64 cells 53 Vmin km h 25 Vmax km h 45 flying weight kg 120 180 150 210 190 250 The total weight in flight is equal to the weight of pilots and all the equipment including the wing Materials canopy material Gelvenor LCN 0066 OLKS Skytex 9017 E38A E29A lines Cousin dyneema 130kg Liros aramid 160 220 340 kg rizers 25 mm zero stretch polyester _ connectors 3 5 mm stainless _ Ri
2. apse in turbulent conditions Asymmetric collapses can be controlled by weight shifting away from the collapse and applying a small amount of brake to control the flight direction At the same time you should use the brake to re inflate the canopy Remember that the deflated glider has higher stall speed and smaller brake travel That is why you should be careful not to pull the brake too hard to avoid stall Deflations Frontal collapse Bi Discovery 3 comes out of symmetrical front collapse by itself You can pull the brakes about a 20 cm to speed the re inflation Full stall Full stall happens when you pull both brakes too hard To return to the normal flight you must release both brakes After this usually comes a front dive with a possible front deflation Just because Bi Discovery 3 warns the pilot about stalling by increasing the brake load it is highly unlikely for you to enter it unexpectedly Deep Stall parachuting To get out of this mode you must pull A risers or swing the wing by pulling and releasing the brakes preferably the first one Asymmetrical stall It can take place when you pull one of the brakes too hard or while spiraling at a small speed in turbulence you increase the angle of attack Rotation in the asym metrical stall is called negative spiral This is one of the most dangerous flying situations In order to get out of asymmetrical stall just release the brakes There may follow side thrust for
3. be physically deformed Spiral dive When you hold either brake down for a long time the glider goes into a fast sharp turn and loses a lot of height The rotation axis can be somewhere between the pilot and the wing The sink rate could be more than 15 m sec To get out of the spiral dive you must release the inner brake Mind that Bi Discovery 3 may take one more turn after releasing the brake While spiral diving the pilot experiences considerable overload up to 3 4g so you can lose orientation Landing In small winds when you have 1 2 meters to the ground you should pull the brakes gently to your arms full length so that you put your Bi Discovery 3 in stall at a height of about 0 2 0 5 m and the horizontal speed is zero In strong winds you must land facing the wind If necessary you can fold the ears As you approach the ground you must take B risers while holding the brakes As soon as you hit the ground you must turn towards the glider and pull B risers running towards the wing If the wing is flopping about a meter above the ground release the B risers and pull the brakes hard to your arms length We do not rec ommend you to use the brakes in the strong wind as the wing could catch the wind and pull the pilot Do not let the glider overtake you and hit the ground with its front edge which leads to increased pressure in the wing and may damage it Deflations Asymmetric collapse Every paraglider may coll

5. ieve its best glide ratio When brakes are pulled approximately 30 cm you get its minimum sink rate In order to slow the glider you can use trimmers We recommend to use trimmers only for landing Turn control In order to make Bi Discovery 3 turn with a minimum sink and radius while pulling the internal brake you should pull very slightly the external one too Use weightshift to decrease the spiral radius If the thermal flow is narrow and strong increase the tilt and the rotation speed by releasing the external brake When you need to turn fast you should swing Discovery 3 in the opposite direction and then pull as hard as needed the internal brake Flying in turbulence You can help your glider to avoid different collapses in turbulence you must fly actively for it When the glider pitches forward use the brakes to slow it if it goes back release brakes These movements can be symmetric or asymmetric Let us remind you once again that you should be very careful choosing the weather to fly Descent Techniques Big Ears While holding the brakes you should symmetrically pull the A lines For direction al control of the glider use the weight shift When you do big ears the horizontal speed increases slightly In order to return to normal flight you should release the A lines and pull the brakes a few times Spiraling is not permitted with big ears because of the increased load on the re maining lines so that they can

7. sers Bi Discovery 3 has the risers scheme A3A 1B5C4 The risers are equipped with trimmers that increases the speed range of the glider Warning You are not allowed to change the paraglider construction except adjusting the brake lines because it might lead to unpredictability in flying and make the pa raglider dangerous in certain flying situations Pre flight check Lines are clear and leading edge i is open Karabiners and maillons are tight All harness buckles are closed Helmets on Check reserve parachute a Wind direction is perpendicular to the glid Airspace is clear Launching Your Bi Discovery 3 can take off with both forward and reverse techniques but for tandem gliders forward technique is preferable Use forward technique when the wind is light or there is no wind Move forward and your glider will start to inflate You must maintain a constant pressure on the risers until the wing is overhead Brake it a little and launch Use reverse technique in strong winds Pull the glider by its A risers When it is overhead pull the brakes to stop the glider then turn and launch In Flight Characteristics Bi Discovery 3 has long brake travel light brake pressure as for tandem and turns very well It also has high resistance to deflations in turbulence Speed control You can change speed by simultaneously pulling or releasing the brakes Flying at trim speed hands up your glider will ach
8. u tral temperature and humidity conditions If you do not use the glider then once a month you should unpack it ventilate 1t well and then pack it back in the rucksack Do not wash Bi Discovery 3 Do not use detergents or solvents Clean dirty places with wet soft cloth or sponge In the end of this manual you can find line plan You can use this plan if you want to order the new line instead of damaged Warrantee and Wing Repairs The producer guarantees the correctness of the declared characteristics and the paraglider s normal performance for one year after the purchase date but no more than 200 flying hours The producer conducts special and after warranty repairs and maintenance at the owners request for an extra price We recommend to inspect your paraglider including checking suspension line strength line geometry riser geometry and permeability of the canopy material one time at two years or every 100 hours of flying time whichever comes first Those inspection must be made by manufacturer or dealer If damaged your Bi Discovery 3 must be repaired by manufacturer or dealer Small holes in Gelvenor fabrics you can repair with silicon clue and a peace of Gel venor cloth Small holes in Skytex may be repaired with sticky rip stop tape Attention please The producer bears no responsibility for non compliance with the stated character istics if the user manual is not followed the paraglider structure is
9. ward with a following wing collapse Self rotation Increasing rotation usually takes place when the pilot has not reacted properly to the asymmetric collapse of the accelerated paraglider Try to slow down the rota tion by counter shifting your weight in the harness and pulling the outer brake If the self rotation is increasing drop the rescue parachute quickly in the direction of the rotation This mode can also take place when you make extreme turns of the _ overloaded paraglider Cravat If the collapsed part of the canopy is entangled in the lines you must try to release it by pulling the ear line If you cannot do it and the rotation is increasing you must use the parachute In flight damage Estimate the damage If a brake has untied no problem as Bi Discovery 3 can be steered well by weight shift and pulling the back risers Even if the damage allows for a sustainable controlled flight you should land as soon as possible If normal flight is impossible you must use the parachute Packing Your glider Try to pack your Bi Discovery 3 as loosely as the rucksack allows because every fold weakens the cloth Special care should be taken about the rib reinforcements Follow this scheme Spread the glider on the ground the bottom surface up Put all the lines onto the canopy The risers can be placed both at the leading or at the trailing edge Fold the canopy from the tips to center Let the air come out from the ca
