parachute

Historians suggest that the idea of skydiving came the legendary Leonardo da Vinci. And the first mention of a safe opportunity to "descend from heaven is in his manuscripts (1495/year):" If a person has a tent of starched cloth, each side of which has twelve cubits in width and height the same, he can jump from any height without putting yourself in any danger ".

Today we no longer need to rush from the sky with a tent, and, after weighing all pros and cons, decide to jump under the guidance of trusted instructors. What do you need for the types of jumps and jump impossible-to whom all these questions concern everyone who wish to get their portion of heavenly adrenaline. So, two variants of jump with a parachute for the first time.

Independent jump with a parachute landing

In this case, you can make the jump from military parachute landing on a round dome with forced opening or three-second delay before opening the parachute. It is believed that such an option choose the truly courageous and determined people.
Especially the jump:
Before you leap, you need to be trained: paperwork, medical board, detailed instruction of duration 3-4 hours (sometimes more).
Jump takes place from a height of 800 meters above the ground, the aircraft speed jump-160 km/h. freefall last for 3 seconds, a speed of 50 m/s.
The falling speed when landing 5 m/s, that is why special attention is paid to the landing phase during the briefing. Inattention to the instruction may entail quite unpleasant consequences!
After the briefing by issuing the command "instructor aboard!" you'll go to the plane (usually, an-2, known as the "crop duster") build (first jump the heaviest).
When forgotten ring of the parachute will open the insurance system.
Restrictions for the weather: wind of no more than 6 m/s, it is desirable to avoid the storm, but in the rain, you can jump, but drag after landing parachute namokšij quite difficult.

Jump in tandem with an instructor

Zatyazhnoj pryzhok parachuting "wing" paired with tandem master. Very reliable version of the first parachute jump. Here you may not need to demonstrate independence and heroic courage, however, you will be able to much longer and in another as enjoy the flight.

  • On board instructor will connect your suspension system. You detach yourself from the helicopter (aircraft) at an altitude of 3500-4000 meters (!). Freefall lasts 50 seconds.
  • All the work to stabilize falling and disclosure of doslidniy performs parachute instructor. You will enjoy the sensations and views almost a minute!
  • The falling speed when landing 1 m/s. landing force can be compared to leap off the couch, so restrictions in health in tandem jumps are less strict.
  • Restrictions for the weather: wind up to 10-12 m/c, cloudy almost does not play a role, because import and emit the GPS Navigator.
  • During jump allowed taking pictures and videos.
Beware of health

Of course, you will pass a medical examination before the jump. But the local doctor can diagnose many diseases about which you know. So be conscious and watch your health.
If you wear contact lenses, there are no problems. And here's the glasses must be replaced with glasses with plastic lenses and an elastic band around the head. If you have severe myopia, from jump better abstain.
Having a musculoskeletal injury in the past, you need to get medical advice. Perhaps, in this case for you suitable only jump in tandem. And fracture feet cannot be parachuting during the year after the complete fusion of the bones.
