Skydiving

Skydiving is a sport in which a person jumps from an aircraft, then free falls for some distance before deploying a parachute to slow their descent back to the ground. Skydiving is also used as a military tactic. It can be a means of quietly getting troops zones.

Can you use a parachute more than once?

Yes and no. Yes because you can fold it back up into its sack. But some kinds of parachutes can not be folded back into its sack. For example a normal nylon parachute can. But a space parachute cant.

How many women have survived skydiving accidents?

Thousands. A skydiving accident can be life threatening, or a sprained thumb. Accidents are usually minor- a less than perfect landing might give a twisted ankle or knock the wind out of you. A bad exit might bang a knee or shoulder. All of these things have happened, but they are all fairly rare.

What are the tandem skydiving age requirements?

You must be at least 18 years old to tandem skydive. Try visiting http://www.skydiveorange.com/faq.htm , they have tons of information regarding skydiving restrictions and requirements.

How long does the average tandem skydive last from door to floor?

There is a formula that works quite well. The first 1000ft takes 10seconds. This is because the initial velocity with respect to the ground is zero so therefore the average velocity to this point is half terminal. Thereafter, it takes 5 seconds for every 1000ft.

Therefore a jump from 12000ft will give you 7000ft of free fall with a deployment at 5000ft. That is 10 sec to 11000ft, then 6 times 5 seconds to 5000ft, a free fall period of 40 seconds.

Keep in mind a heavier Tandem passenger will have a bit less time, and a small Asian woman or a child will have a bit more.

More bang for your buck, call Jenny Craig. Check out the Tandem Instructors and go for the smallest. That will give you a bit more FF.

Because of the lower air pressure at higher altitude, this formula is not quite so good for 16000ft or 20000ft Tandems.

How heavy can you be and still skydive?

You need to be a generally healthy human being with an average fitness level. 100kg - 110kg need to be assessed on the day.

Where did skydiving originate from?

This is debated with some saying it happened in the 17th century or even earlier in the 12th century by the Chinese.

However, the first documented case of a parachute jump (not a freefall skydive) was by Jacques Garnerin in 1797.

The first freefall with a packed parachute was by Georgia Broadwick in 1914. She opened her parachute herself instead of using a static line.

What size of parachute makes a free fall slower?

Depends what you mean by "better". A bigger parachute provides more wind resistant so if you were to jump out of a plane, you would want to go big. If your talking speed (like a running parachute) you would want a small parachute to accommodate how much harder you want to make your run

How does a parachute fly?

A parachute floats by "catching" the air to slow descent.

Will the weight of the skydiver affect the fall time?

The weight of the sky diver has minimal effect on freefall time. Body position and amount of surface area exposed for wind resistance to affect are the two largest factors, and are interrelated to one another.

What force is increased after the skydiver open parachute?

To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.

What are all of the parts of a parachute and what are all their roles Physics?

there are three main parts that come with a parachute. there's the chute, the draglines, and the weight or mass (could be a human). then there's also the hole in the top of the chute.

Is a parachute kept in a bag?

No a bag is not a good parachute especially a paper bag

Do certain people go parachuting?

the way i see it is that if parachuting is an extreme sport that they would announce it on the radio or tv so your answer is no it is not i've went before though its fun

What are the stages of parachute jumping?

I wouldn't say there are any actual "stages." The general outline of a jump; plan the jump and practice on the ground, climb to altitude, exit, do whatever was planned, breakoff (get separated), open, land.

There are a lot of different things to do in skydiving, so that outline can change plenty.

How does friction relate to skydiving?

  • The more friction you have the more grip your parachute has in the air. This is most apparent in the type of fabric used in the construction of parachutes. There are 2 basic types - F111 (which is porous) and Zero Porosity (which is a lacquered material). Zero Porosity or ZP type parachutes tend to fly faster through the air.
  • In swooping competition parachutes, the thinner the suspension lines, the faster you can fly also. This has is directly related to friction, drag and overall weight.
  • Parachuting discusses an open parachute. Skydiving is the element where you are free falling with a packed parachute on your back. Most skydivers wear a full-body jumpsuit. The rougher the material, the slower you fall. Often in the case of larger heavier skydivers, their suits are made of cordura to slow them down. Ripstop nylon is used for lighter weight skydivers.

Can you sky dive with dentures?

Skydiving with dentures will not affect the skydive in any way. However, it is possible to lose your dentures on a skydive. There are multiple videos on youtube depicting people losing their dentures on a skydive. So while it will not affect your skydive, you may want to leave them on the ground so you do not lose them.
Put simply, the answer is yes. They must be well fitted however so as not to come loose during freefall. Tell your dropzone when you are booking so that they know.

How much money does a professional skydiver make after 40 years?

PROskydiving reimburses DZs via ACH transaction every Monday at a rate of 85% their normal rate assuming they link back to PROskydiving. Without a link, they get 80%.

What was the highest altitude of parachuting that has been used?

usually drop zones highest drop height is 14000ft but some go up to 16500ft like one in New Zealand named Skydive Abel Tasman

How many skydivers in the US?

This question is the one most frequently asked of dive-training agency PADI (the Professional Association of Diving Instructors). The truth is, nobody knows for sure. There are several diver certification agencies in the US, and more in other countries. Until recently these agencies didn't share certification data. Then there's the question of how one defines "diver". Does this refer to "certified" divers or "active" divers. It's true that nearly all divers are certified divers, but only a small percentage of people with a diving certification make more than five divers per year.

The topic was explored at some length by Ben Davison in the May 2007 issue of his dive-industry magazine "Undercurrent". While PADI and other agencies often suggest the number is "2.5 to 3 million", Davison believes that this number is significantly inflated. Most of us who have spent some time in the diving industry agree. Davison's best guess is there are probably about 1.2 million "active" divers in the United States, where "active" is defined as making at least 5 divers per year.

What state can you skydive at 11 years old?

Generally at any drop zone in your state. Although if you want to go tandem, ( attached to a pro, definatley reccomended for a first time) then you have to wait until your 18. 16 You have to do a static line ( look it up) or go to Canada or Russia you can do it any age over there!

Is sky diving one word?

Of course. for example, "I went skydiving on saturday" or "I take skydiving lessons"

What forces act on a skydiver as they are diving?

when a skydiver jumps out of a plane, the dominant force is gravity, pulling him/her towards the ground, although some air resistance is also acting on him/her, allowing him/her to fall at a steady speed (not dropping like a stone), so the forces acting on the skydiver are almost balanced. of course, all that changes when the parachute opens. then the air resistance greatly increases, drastically slowing the descent down to earth.


What is the best country to sky dive?

Skydiving is popular in many countries. I will list some countries that have skydiving and make some comment about the type of skydiving offered.

I think it is a fair bet to say that if a country has a military, it probably has at least military skydiving.

New Zealand has military and sport jumping. The views are spectacular with the beautiful Bay of Islands in the North with ocean and island scenery, to the lakes and mountains of Queenstown and Glenorchy in the South.

Australia has military and sports skydiving with spectacular views of coral reefs from the air to barren desert.

Fiji has sports jumping to my knowledge with the emphasis on tandem. Skydiving is very big in the US and probably has the most jumping. Not so big in the United Kingdom with the weather issues but still is on offer. France Germany Spain, (very popular) Italy Hungary Russia, there is probably not many countries in Europe that don't have some skydiving.

The United Arab Emirates are mad on skydiving and with the financial backing available have been able to finance world record formation jumps successfully.

To be frank, perhaps it would be easier to list countries that don't have skydiving. People have even jumped at the North Pole and above Everest.

I would welcome comment on this. Perhaps your country hasn't been mentioned and you are a jumper.

How changing the weight on a parachute makes it go slower?

A parachute must have suspended weight in order to open. If you have no weight loading the parachute will fail.
