The first step in the development
I hope that my comments above will to understand what is happening during the turn. In short, both types of turns lead to an increase in vertical and horizontal speed, but for a planned maneuver, turning with front free ends is generally preferable as leaving a larger “gap” in case of calculation errors or a sudden change in the situation. Unfortunately, the majority of unplanned, “panic” turns are made by just the brake calipers, which led to a considerable number of accidents. Regardless of whether a turn is made at the free ends or brake lines, whether it is planned or not – if the withdrawal is not completed before the meeting with the land, the consequences may be dire.
The main circumstance to be remembered is that the force of an impact increases geometrically with increasing speed. Calculated kinetic energy = 1/2 body mass x squared velocity. If a collision is unavoidable, it is better to have a low speed. Consider, as an example, two collisions with the ground after a low turn, one at a speed of 15 km / h and the other – 45 km / h. In both cases, the subject of the experiment is a stuffed parachutist weighing 80 kg. 1/2 x 80 x 152 = 9000 “pain points” – the consequences, for example, in the form of abrasions and sprains. 1/2 x 80 x 452 = 81000 points – nine times more painful. It is the square of speed in combination with modern loaded domes that causes such a significant number of fractures of bones, spines, and so on.
Another point associated with the proliferation of fast domes – their management requires such a significant concentration of attention that it does not remain on other, equally important factors. If all your attention is spent only on calculating and performing a landing, you do not have it left to follow the rest of the people in the air. And attention on the crowded landing area, with different speed domes requires quite a lot. If you only have time to fly your own parachute, you will not be able to land safely alongside others.
The only possible way to make beautiful landings is a slow, gradual improvement in the technique of their execution. One must be always ready to sacrifice a beautiful approach for the sake of a safe one. It should also be remembered that high flying qualities are the result of not only the appropriate equipment, but also piloting techniques. Instead of changing to a higher speed dome to maximize the “buzz” of a flight, skydivers should strive to get the best results from their existing domes. Only as much as possible having mastered all aspects of piloting on a familiar dome, one can move on.
The first step in the development of the landing technique is traffic management, control over the air situation, without which a safe approach and landing is impossible. It is necessary to learn to recognize the flight characteristics of various domes in order to maintain a safe distance between parachutists not only horizontally but also vertically based on this knowledge. In other words, it is necessary to develop the ability to “hang” (slow turns on pinned toggles) in order to skip forward faster domes, and the ability to quickly lose height using turns to outrun the domes slower. Little by little, even when jumping with a large number of people on board, you learn to do without competition for the landing site.
