Hello there! My name is Owen and I have been a paragliding coach in England for many years. Nonetheless, all information provided herein is purely a reference, not a consultation, and any action you take is your responsibility. Paragliding is a dangerous sport and you should consult a fully qualified coach before attempting any of the following operations. If you are not eligible for a fully approved and licensed school, you do not have air operations other than as a paid passenger.
This article is about fast falling technology. As a paraglider pilot, we spend most of our time trying to get up and spend very little time trying to take off. Unfortunately, the era in which we really want to collapse is usually the most serious. There is no benefit in all the prayers in the world; good training and advance planning. If you are in trouble from

Using the fast descent technique then you are already full, but we are dealing with an invisible element here, so this is not difficult to do.
big ear
The most common fast descent technology is Big Ears. Since this is usually taught at school, it is usually considered a safe technique, it is mainly, but I have seen it very much wrong more than once. Changing the shape of the wing from the best form of flight is a dangerous process, but if conditions change, it may be better than an alternative. Most accidents using large ear techniques occur due to poor training or a lack of understanding of the forces involved. Here are a few things to keep in mind [although these from

Constantly updated, so be sure to verify with the current coach]:
- Every "ear" should be discarded one at a time, not together. This is debatable, but since the main danger of pulling into the ear is an increase in the angle of attack [due to the steep speed of the glider], the glider is closer to the stall point. Therefore, it is a priority to gradually reduce the sudden change in the angle of attack by staged [one ear at a time]. You will often see the pilots close together, but this can be a catastrophic mistake, as I have witnessed.
- A good way to reduce the angle of attack is to use a speed bar. Before pulling your ears, you should make sure your feet are on the speed bar, and once your ears enter and your wings are stable to push the bar, you don't have to stretch completely. Be careful not to use your bar from

Pull your ears, or you can get the front folds. - In this case, the wind gradient is your enemy. As the wind speed increases, you are likely to use large ears, but lowering the wind speed by lowering the wind gradient will result in deep stalls, which can be considered by increasing the angle of attack. A low level of deep stall is very dangerous because you don't have time to recover. Similarly, the speed bar can help prevent deep stalls, but keep in mind that the danger is the closest to safety.
- Don't pull out your ears. In the past, this technique was taught at school [with brakes to withdraw from the big ears], but now it has lost its credibility. Pulling the brakes will further increase your angle of attack and bring you closer to a gear. To quit, simply release the a line and let the ears unfold. On some higher performance gliders, the ear may stay inside, so if you are flying on a DHV 1/2 glider before flying, please read the manual.
This operation is only for good heights [at least over 500 feet] and should not be used close to the ground. The danger is that the glider will not recover and enter deep stall. To restore deep stalls, you should use some speed bars, which will lower your angle of attack to the normal range of flight, but at low levels, this may not be an option. The B-line gear is used to escape the cloud, not to land.
Spiral diving
Spiral diving is also a rising method of descent, not a low landing. The spiral is very disoriented and may turn black due to the g force involved. Another danger is locking, the wing does not appear without the pilot input [or it may actually tighten when the brake is released], which combined with the directional obstacle and the descent speed may mean a big one. The hole in your shape is on the ground. In theory, entry-level gliders should get out of the spiral quickly and automatically, but recent evidence suggests that this is not always the case, in part because of variables such as pilot height, weight, center of gravity, and whether you are using cross-supported seat belts.
Another problem with spirals is that unless you know what you are doing, exiting may be more troublesome than when you started. The spiral needs to exit slowly because otherwise all the energy [and those energy] from

Emergency turn [wingovers]
An emergency turn will disappoint you, but your wing is essentially unstable during this process, plus the wind gradient and any low-level turbulence you may encounter, you just ask for a crash. not suggested.
Asymmetrical folds caused by pilots
Similar to the big ear, this technique involves only one side of the wing. This means you don't have a real choice to reduce your angle of attack and still have a higher angle of attack on the side of the wing you are flying. In addition, if you fall too many wings at the wrong time, you may get a complete spiral of the front or collapse. Big ears are a safer choice, which is why it is taught at school.
All in all, Big Ears is the safest low-speed flying fast drop technology, and the B-line gear is the most useful for advanced flight. None of the above techniques should be tried for the first time when you need it, but there is a rehabilitation boat in the SIV course at school or on the water.
The main danger of any of these technologies is ignorance, especially for large ears, where the pilot often fails to keep abreast of the latest developments in the sport and often does not perform correctly. Remember: you may be a qualified pilot, but the sport is still very young and the air is ruthless. keep status quo.
