Introduction BASE 3 OWNER’S MANUAL Solo paraglider | EN / LTF B Introduction Welcome to BGD, a world leader in the design and production of paragliders. For many years Bruce Goldsmith and team have been developing products with world-beating performance for pilots who want the best. We apply our competitive knowledge to design top quality products that combine the highest performance with the safe handling our customers value and respect. -
Page 5: Limitations
Introduction Limitations Suitable for ... Tandem Yes – Both pilot and winch operator should have the necessary training and qualifications for Towing towing, and the tow system should be certified for paraglider use. Paramotor Not yet tested Warning Do not perform spiral dives with big ears or asymmetric collapses. The high G loading on fewer lines could overload and break the lines. -
Page 6: Warranty
Introduction Warranty Information about the BGD warranty can be found on the Warranty page of our website. In order to benefit from it, you warranty registration form on the website. must complete the It is your dealer’s responsibility to test fly the paraglider before you receive it, to check the trim settings are correct. Please check that this has been completed. - Page 7 Introduction Brake line lengths The length of the brake lines is set at the factory so that the trailing edge is not deformed at all when brakes are not applied. There should be around 7cm slack in the brake lines, before they take effect on the canopy. It should not be necessary to shorten the brake lines.

Page 8: Preparation And Pre-Flight Checks
Preparation & Pre-flight checks Preparation and Pre-flight Checks Setting up the speed bar The BASE 3 has accelerator risers, with Brummel hooks to attach a speed bar. The glider can be flown with or without a speed bar attached. The speed bar should be connected and adjusted following the instructions in your harness manual to ensure correct routing of the lines. -
Page 9: Pre-Flight Checks
Preparation & Pre-flight checks Pre-flight checks Your paraglider is designed to be simple to inspect and maintain but a thorough pre-flight procedure is mandatory on all aircraft. The following pre-flight inspection procedure should be carried out before each flight. 1. Whilst opening the paraglider check the outside of the canopy for any tears where it could have been caught on a sharp object or even have been damaged whilst in its bag. -
Page 10: Flight Characteristics
Flight Characteristics Flight Characteristics This manual is not intended as an instruction book on how to fly your paraglider – you should be a qualified pilot. The following describes how to get the best from your wing. Take-off The glider is easy to inflate in light or stronger winds and will quickly rise overhead to the flying position. It will launch easily using either the forward launch technique (best for light winds) or reverse launch (best for stronger winds). -
Page 11: Active Piloting
Flight Characteristics Turning Your wing does not require a strong-handed approach to manoeuvring. For a fast turn smoothly apply the brake on the side to which the turn is intended. The speed with which the brake is applied is very important. If a brake is applied fairly quickly the canopy will do a faster banking turn, but care must be taken not to bank too severely. -
Page 12: Speed System
Flight Characteristics Care must be taken not to apply so much brake as to stall. This is easy to avoid as the brake pressure increases greatly as you approach the stall point. Only fly near the stall point if you have enough height to recover (at least 100m). -
Page 13: C-Steering
Flight Characteristics The dyneema line that connects the speed system in the risers is designed to have a small amount of slack in it, in order to obtain the correct riser lengths when accelerated. The amount of slack in this line varies with wing size and determines the B riser length when fully accelerated. - Page 14 Flight Characteristics C-steering C-steering handle speed riser FIG. 1: Keeping the brake in your hand, grasp the C-steering handle with your fingers to apply pressure to the C’s. Base 3-manual-EN-v1.0 October 2024...
- Page 15 Flight Characteristics Rapid descent procedures Big Ears The wingtips of your paraglider can be folded in to increase its sink rate. Big Ears allow you to descend quickly without substantially reducing the forward speed of your glider. To engage Big Ears, lean forward in the harness and grasp the outer A-lines, or the maillons of the ‘Baby-A’ risers, keeping hold of both brake handles if possible.
-
Page 16: Landing
Flight Characteristics B-line stalls are useful if you need to lose a lot of height quickly, perhaps to escape from a thunderstorm. They should not be performed with less than 100m of ground clearance. Spiral Dive A normal turn can be converted into a spiral dive by continuing to apply one brake. The bank angle and speed of the turn will increase as the spiral is entered. - Page 17 Flight Characteristics Strong-wind landings require a different technique. If you use the brakes to flare in a strong wind the wing tends to convert this energy to height, which can be a problem. The best method in strong winds, is to take hold of the rear- risers at the maillons just before landing, and collapse the canopy using these when you have landed.

Page 18: Recovery Techniques
Recovery Techniques Recovery Techniques Test pilots have tested the glider well beyond the normal flight envelope. Such tests are carried out in a very precise manner by trained test pilots with a back-up parachute, and over water. Stalls and spins on any paraglider are dangerous manoeuvres and are not recommended. -
Page 19: Spins
Recovery Techniques Recovery from deep stall is quite simple: The normal method is to simply initiate a mild turn. As the canopy starts to turn it will automatically revert to normal flight, but it is very important not to turn too fast as this could induce a spin. The second method is to pull gently on the A-risers. -
Page 20: Asymmetric Front Collapse
Recovery Techniques Asymmetric Front Collapse Your paraglider is very resistant to deflations; however if the canopy collapses on one side due to turbulence, you should first of all control the direction of flight by countering on the opposite brake. Most normal collapses will immediately reinflate on their own and you will hardly have time to react before the wing reinflates automatically. -
Page 21: Maintenance
Maintenance Maintenance Packing We recommend concertina-packing the wing as it helps to extend its life. Always start with a bunched glider. Do not lay it out, as this would mean pulling it across the ground when you gather the leading edge, risking damage from abrasion. -
Page 22: Small Repairs
Maintenance Your paraglider is made from high quality nylon which is treated against weakening from ultraviolet radiation However, UV exposure will still weaken the fabric and prolonged exposure to harsh sunlight can severely compromise the safety of your canopy. Therefore once you have finished flying, put your wing away. Do not leave it laying in strong sunshine unnecessarily. -
Page 23: Lines
Maintenance Lines Releasing loops on the rear lines All BGD gliders are rigged from new with loops on the maillons of the C lines (and D lines if any) plus the stabi line. The loops are there so that they can be released to compensate for any shrinkage of the back lines as the glider gets older. - Page 24 Maintenance received the new ones or you may end up not being able to fly! Sometimes only a part lineset is needed (eg excluding top lines or brakes) so take care not to cut any lines that need to be retained. Correct alignment of lines It is important that the lines are mounted the correct way up.
- Page 25 Maintenance Not Reinforced Reinforced Reinforced Not Reinforced Attaching the lines All the lines are connected to other lines or to tabs with lark’s foot junctions. Make sure that they are joined correctly with interlocked junction and not looped junctions. Base 3-manual-EN-v1.0 October 2024...
- Page 26 Maintenance Interlocked junction – correct Looped junction – incorrect Interlocked junction – correct Looped junction – incorrect have black to prevent them from accidentally coming undone and the lines from falling maillons plastic inserts out. Always ensure that they are correctly installed after rigging the glider. If they are lost, use a line lock insert to hold the link closed.

Page 27: Servicing / Inspection
Maintenance Servicing / Inspection It is important to have your glider regularly serviced. Your wing should have a thorough check / inspection every 24 months or every 150 flight hours, whichever occurs first. This check must be made by the manufacturer, importer, distributor or other authorised persons. -
