Safety

Despite the perception of danger, fatalities are rare. But each year the number of people are injured or killed in the world jumps. About 21 skydivers are killed each year in the U.S. with one death every 150.000 strokes (about 0.0007%).

In the U.S. and most western world skydivers are required to have two spadochrony. Spadochron reserve must be regularly checked and re-packed (whether used or not) by a certified parachute rigger (in the United States, the FAA certified parachute rigger). Many skydivers use an automatic activation device (AAD) that opens the reserve parachute at a safe height should not activate the main canopy themselves. Most skydivers wear a visual altimeter and the number increases the use of acoustic altimeters installed on the helmet.

Changing wind conditions is another risk factor. In conditions of strong wind and turbulence during the hot days the parachutist can be caught in downdrafts near the ground. Wandering winds can cause the wind crosswind landing, or have high growth potential injuries due to the addition to the wind speed at the speed of the landing.Another risk factor is a "canopy", collisions, or collisions between two or more paratroopers Parachute fully inflated. Canopy can cause collisions inflated parachute jumpers to get entangled with each other, which often leads to sudden collapse deflation paragraph) from one or more involved parachute. When this occurs, bridges often must quickly carry out emergency procedures (if enough height to do it) to "cut-away" (RID) of its main halls and reserve parachute to deploy. Canopy collisions are especially dangerous when they occur at an altitude too low to allow enough time to get rid of the bridges of their main parachute safely and fully deploy the reserve parachute.

Equipment failure rarely causes fatalities and injuries. About one in 750 deployments of the main results of a faulty parachute. Ram-Air parachutes typically spin uncontrollably, when damaged, and should be discarded before deploying reserve parachute. Reserve parachutes are packed and deployed differently, but there are also more conservatively designed and built and tested to more demanding standards and are therefore more reliable than main parachutes, but the real benefit due to the probable safety of failure multiplied by the unlikely probability of failure up yet less likely. This gives even lower probability of a double fault, although the possibility of a major accident may not be cut, causing damage to the reserve is a very real threat.Parachuting disciplines such as BASE jumping or those involving equipment such as wing suit flying and sky surfing have a higher risk factor due to the reduced mobility of the bridge and an increased risk of entanglement. For this reason, these disciplines are generally practiced by experienced jumpers.Images from popular movies, including action movies - usually exaggerates the danger of the sport. Often the heroes of these films are shown feats that are physically impossible without the help of special effects. In other cases, their practices would cause them to be grounded or rejected in any security conscious drop zone or club. Member of the USPA drop zone in the U.S. and Canada must have an experienced jumper act as a "safety officer" (in Canada DSO - Drop Zone Safety Officer in the U.S. S & TA - Safety and Training Advisor) who is responsible for dealing with bridges that violate the rules laws, regulations or act in a manner deemed unsafe by a designated person.In many countries, if local laws or Prudence aware of the responsibility Dropzone owners require that parachutists must have reached legal age before participating in sports.

Parachuting

Parachuting, also known as skydiving, is the act of leaving the plane and return to Earth with the help of gravity when using a parachute to slow during the end of the meeting. You may or may not involve a certain amount of free fall, the time during which the parachute failed to deploy and body gradually accelerates to terminal velocity.

The story starts jumping Andre-Jacques Garnerin who managed to jump from the hot air balloon in 1797. The military developed parachuting technology as a form of rescue teams to disaster aboard balloons and aircraft in flight, and later as a way to deliver troops into battle. Early competitions date back to 1930, and became an international sport in 1952.Parachuting is performed as a recreational activity and competitive sport as well as the deployment of military airborne and occasionally forest firefighters.Skydiving Center, surgery may be commercial or club, usually works at the airport and offers one or more aircraft, which takes groups of skydivers for office. Puente individual can go in a light aircraft as Cessna C-172 or C-182. In the crowded drop zones (DZ) larger aircraft can be used as the Cessna Caravan 208, De Havilland Canada DHC-6 Twin Otter or Skyvan Short.A typical jump involves people who come on board (usually by air, but sometimes a helicopter or even a balloon), anywhere between 1,000 and 4,000 meters (3,000 to 13,000 feet) high. If you jump from low altitude, the parachute is deployed immediately, but at higher altitudes, the bridge can easily fall for a short period of time (minutes) [1] Before activating a parachute to slow the landing speed (5 7 minutes).

When the parachute opens (usually the parachute will be fully inflated by 800 meters or feet 2600) bridge can control the direction and speed of the switches at the end of the control lines connected to the trailing edge of the parachute and may seek the landing and stopped by a relatively soft. All modern sport parachutes self-inflating "ram-air" wings that provide control of speed and direction similar to the related paragliders. Purists of any sport that takes into account that the paragliders have a much wider range of elevation, but that parachutes are designed to absorb the stresses of terminal speed enforcement.

By manipulating the shape of the body in freefall, skydiver can generate turns, forward movement, backward movement, and even pick up.After exiting the plane, for a few seconds bridge continues to travel forwards and downwards, due to the momentum created by the speed of the aircraft (known as "forward pull"). Perception of changes from horizontal to vertical flight is known as the "relative wind", or informally as "being on the hill." In freefall, skydivers generally do not experience the "fall" sensation, because wind resistance in the body at speeds above 50 mph (80 kmh) provides some sense of balance and direction. A normal output speed of the aircraft (about 90 mph (140 kmh)), there is little feeling of falling just after exit, but jumping from a balloon or helicopter can create this feeling. Skydivers reach terminal velocity (about 120 mph (190 kmh) in the belly to Earth orientations, 150-200 mph (240-320 km / h) in the orientation of the head down) and no longer accelerated towards the ground. At this point, the feeling is like a strong wind.12-way formation with Videographer can be seen in the upper right cornerJump of the Russian flag

Many people make their first jump with an experienced instructor and trained - this type of jump can be in a tandem jump. During the tandem jump instructor is responsible for the procedures to combat the crisis in the unlikely event that they need to release the student to concentrate on learning skydiving. Other training methods include static line, IAD (Instructor Assisted Deployment) and AFF (Accelerated Free Fall) aka Progressive Free Fall (PFF) in Canada.

Skydiving

Skydiving, downhill sport, similar to part with a parachute from an airplane or ship. He participated in both recreational and competitive sports activities in the three phases of activity Skydiving: Free fall, with an open parachute descent and landing. In the autumn contest participants are judged according to their style in free fall and precision landing at some point. During the descent, divers are able to check the accuracy of their landing by manipulating the open parachute as a candle kind of qualified parachutists with good equipment, to travel in a horizontal position to 10 miles at 16 miles) per hour at a normal fall. For security reasons, the paratroopers will be forced to open the parachutes at about 2,200 feet (670 m). Skydiving is a competitive sport after World War II. In 1951, the International Federation of Airline promoted (founded 1905), most of the organizing body for air sports, the world's first skydiving. In the United States Parachute Association USPA U.S., founded 1957) sponsors the annual championship. At the beginning of the 21st century. Interest in traditional skydiving waned as a member of the USPA fell. At the same time interest in piloting the canopy, or chopped, grew. Launched in 1990, is the only kind of skydiving jumps, see where the bulk of their moves from the ground. Chopped and offers greater speed and danger that traditional skydiving is maneuvered near the ground or water, sometimes only inches and is activated at lower jump heights and the use of parachutes more smaller, more agile.
