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.
