13turbulent conditions. If necessary you will have to constantly adjust themovements and pressure on the accelerator whilst constantly adjustingthe pressure applied to the brake lines. This balance is considered to be“active piloting.” If we choose to fly with the trimmers opened while usingthe accelerator caution should be heightened in turbulent air conditions.4.4 FLYING WITHOUT BRAKE LINESIf, for any reason at all, you cannot use the brake lines of yourDOBERMANN you will have to pilot the wing using the d-risers and yourbody weight to fly towards the nearest landing. The D-lines steer easilybecause they are not under pressure; you have to be careful not to overhandle them causing a stall or negative turn.The trimmers must first be rolled-up before landing, and let the wingfly at full speed and before reaching the ground you will have to pullsymmetrically on both the D-risers.This braking method is not as effective as using the brake lines so youwill land at a higher speed.4.5 KNOTS IN FLIGHTThe best way to avoid these knots and tangles is to inspect the linesbefore you inflate the wing for take-off. If you notice a knot beforetakeoff, immediately stop running and do not takeoff.If you have taken-off with a knot you will have to correct the drift byleaning on the opposite side of the knot and apply the brake line on thatside too. You can gently try to pull on the brake line to see if the knotbecomes unfastened or try to identify the line with the knot in it. Try topull the identified line to see if the knot undoes. Be very careful whentrying to remove a knot. When there are knots in the lines or when theyare tangled, do not pull too hard on the brake lines because there is anincreased risk of the wing to stalling or negative turn being initiated.Before trying to remove a knot, make sure there are no pilots flyingnearby and never try these manoeuvres near the mountainside. If theknot is too tight and you cannot remove it, carefully and safely fly to thenearest landing place.5. LOSING HEIGHTThe knowledge of the different descent techniques is an importantresource to use in certain situations. The most adequate descent methodwill depend on the particular situation.The following indications should be viewed as purely informative, solelyrelevant to normal flying settings, and can not to be considered norviewed as a paragliding teaching manual. Only professional paraglidingschools can teach and prepare pilots to do all these maneuvers.5.1 EARSBig ears is a moderate descent technique, achieving about –3 or –4 m/sand a reduction in ground speed of between 3 and 5 km/h. Effectivepiloting then becomes limited.To apply ears select the outermost A-line from each stabilizer as highup as possible and pull them outward and downward in a smooth andsymmetrical motion. The wingtips will then fold inwards.Releasing the lines will see the wingtips re-inflate automatically. If theydo not re-inflate, gently pull on one of the brake lines and then on theopposite side. We recommend that you re-inflate asymmetrically, thiswill reduce the risk of altering the angle of incidence which should beavoided, more so if you are flying near the ground or flying in turbulence.5.2 B-LINE STALLWhen you carry out this manoeuvre, the wing stops flying, it loses all
