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.

When a skydiver jumps from a plane he is in a condition known as what?
Panic?
Terror?
Exhilaration?
No, "FREE-FALL". Although one or more of the first three are likely, as well.
By the way; a skydiver is only in freefall for about a second after the jump. After that, the air resistance of his body begins to slow him down until he reaches "terminal velocity".
Can you sky dive with only one leg?
[left leg through the knee amputee]
Yes. I recently started. Done 10 jumps so far and happy to continue.
How does skydiving affect heart?
When free falling, you will experience high speed winds pushing against your body and it will feel like you are floating and not falling. You will feel a rush of air past your ears. There is some speculation that in the long term you may have some hearing loss. When the chute opens, you will experience 3-4 g's. This has no bad effect, but if you have back problems it can be a major problem. Another effect is just the pure excitement.
How far do most skydivers fall?
The altitude of which a skydiver jumps from depends on different variables such as the type of plane and also the style of fall. Plus, beginner skydivers are usually falling tandem as most instructors will not allow them to jump alone. The typical altitudes are between 12,500 feet above ground level and 18,000 feet above ground level.
The motion of the parachutist after he pulled his rip cord made him appear to be moving upward?
Skydivers do NOT move upwards at all when we open our parachutes. We don't even bounce a little. That is an illusion caused by the camera operator still falling at full speed while the first jumper opens their parachute and slows.
Now, it is possible to move upwards in some limited circumstances. When exiting a fast-moving aircraft while wearing a wingsuit, you can rise above the plane for a (very) short time. Also, once your parachute is open, you can flare your canopy enough to slightly (by a few feet) gain altitude.
Why does the downward velocity of the parachutist decrease after the chute is opened?
There are 2 types of parachute - the round parachute and the more modern wing parachute. The round parachute is a decelerator and works on drag only through the atmosphere. However, with the wing shaped 'square' parachute, they act with an additional force of lift. Another name for this type of parachute is the Ram Air Parachute.
Whilst few of them ever generate enough lift to gain altitude, they do create masses of forward motion which gives them better range to land back on the dropzone. You also get better, safer landings which are easier on the knees! Most dropzones these days only use squares.
I would recommend a tandem jump for your first one which uses this more modern type of parachute.
A parachute is deployed using a smaller drogue pilot chute which drags the main parachute off the container. The container is a combined harness which holds the packed parachute on your back. As the parachute inflates, it will slow you down from 120mph to around 10mph average. The final stage is landing, where the skydiver pulls down on both steering toggles to further slow down the decent rate for a tip-toe soft landing.
What doesn't affect rate of descent for a parachute?
Parachutes are interesting aircraft. The major retarding force of classical round parachutes is drag. Weight and drag determine their rate-of-descent. But air spills out of them because they oscillate, too. Since the 1960's parachutes have been designed that acheive lift from their forward motion.
How fast does a human travel in freefall in skydiving?
Terminal velocity is not a predetermined speed. Terminal velocity is the condition in which the forces of gravity and drag are equalized, and no further change in speed is possible if these conditions remain the same. However, terminal velocity can vary greatly depending upon altitude, wind resistance of an object, atmospheric conditions, and other factors.
Do you have to jump tandem for your first skydive?
NO, the Accelerated Free Fall program allows the student to jump for the first time with two instructors holding onto their parachute harness. The program begins with a 4-6 hour ground-school course and then a minimum of 7-8 jumps that require the student to progressively demonstrate new skills they have learned on the ground. From the first jump, the student is fully responsible for the proper timely deployment of their parachute, fixing any unlikely malfunctions of the parachute, and safely landing.
What is the parachute made of?
Parachutes are not rated by their speed.
A parachute works by increasing the air resistance of a suspended falling body or object. The greater the mass of the object the larger the area of the parachute must be to reduce the speed to an acceptable level.
What is the minimum skydiving height?
Thee is not exactly a set height limit unless you are a tandem student. Solo skydiving is not a problem but tandems have height and weight restrictions. By this i mean your body weight and height must be in proportion to each other.IE Someone who is 5 ft 3 and 15 stone, no chance!
Is there any indoor skydiving places in pa?
These are;
Canton Air Sports
SkyDive Columbus
Cleveland Parachute Center
Start Skydiving
Skydive Rick's
Aerohio Skydiving Center

Did anybody go sky diving and get killed?
In 2005 there were 27 deaths, and 2.1 million reported skydives.
(This is not "lots" of deaths in comparison to any other "extreme" sport.)

- Click on the link to your right for more information.
- Of Course, But! The experience is awesome! An expensive sport. But worth the experience! Try it sometimes!
- There are lots of deths in Skydiving because you never know what is going to happen after you jumped off from the plane
Almost all skydiving deaths are down to incompetence. The training is safey, safety safety, so just do what they tell you and you should be fine!
How much would going skydiving cost?
The price varies quite a bit depending on the location (also known as a dropzone) and altitude you choose to jump from. Pricing for a tandem jump in the US varies from $100 to $350. The former will usually get you up to 10,000ft and the latter will usually get you a jump from 18,000ft. For $36,500 you can do a tandem jump at Mt. Everest (29,035ft - 8848m).
What do you call a person who jumps from a plane with a parachute?
A paratrooper?
Either that or SkyDiver
Is it possible to engage in skydiving on the moon?
This depends on the gun and type of explosive charge. If it contains its own oxidizer, it might fire.
Wind primairly affects a parachute at landing causing turbulance, and where ground speed becomes a factor. If flying a ram air parachute with the wind, your ground speed will be wind speed + canopy speed, so not a good configuration to land. Also, wind causes turbulance, which can collapse a canopy.
What are the lowest and highest terminal velocity while skydiving?
In a belly to earth body position, the average terminal velocity of a skydiver is around 120mph. This takes approximately 10 seconds to reach this speed. The most common discipline in the sport is formation skydiving and that takes place in this orientation.
However, the terminal velocity of a skydiver can have variables which can greatly affect this speed:
- The clothing / jumpsuits they wear. Skin-tight nylon is more aerodynamic than rough cordura material. Heavier jumpers tend to wear cordura in their jumpsuits.
- The size and weight of the skydiver. A tall thin person will need to near skin-tight clothing to increase their speed. Otherwise they may fall around 10mph slower. Visa verca a small heavy person may need a baggy cordura jumpsuit to help them reduce their fall rate.
- The orientation of the skydiver. In addition to the belly-to-earth body position, there is also a headup/headdown body position which is used for the discipline of freefly. This is around 150 to 160mph. In fact, in the discipline of speed skydiving, the jumper has no official terminal velocity as they accelerate for the duration of the freefall, often reaching speeds in excess of 300mph.
Whit is the cause of most skydiving accidents?
Over confidence and unfamiliarity with advanced equipment.
What is e advantages of skydiving?
For me skydiving is one of the most amazing sports in the world. There isn't just one reason why I do this extreme sport. But in short:
- The sport is a great leveller of people. You get to meet with and become friends of people from all walks of life, educated, uneducated, bricklayers, layers, posh, not-so-posh. When we skydive, there is no class divide.
- The human body was never designed to fall. So in freefall it gives you a small glimpse into what it must be like to be a bird. Flight put simply, is a beautiful thing.
- You get the opportunity to combine many skills - the ability to think fast, to work in a team, to compete, to communicate in freefall, to navigate and to bend air forcing you to change direction or orientation quickly.
- There are many dropzones, competitions and events which are held around the world. So you get the chance to travel and experience the world from a different perspective.
I jump at a dropzone called Skydive Hibaldstow located near to York, UK. There, they jump from 15000ft. From that height you can see all the way to the coast some 20 miles away. It makes for a beautiful view which in turns makes the sky diving experience even better.
How do you dive wile sky diving?
You breathe underwater using a a open circuit breathing apparatus which is commonly known as "S.C.U.B.A." : self contained underwater breathing apparatus.
The diver carries on his back a aluminum or steel tank, which holds compressed air.
The compressed air is reduced to a safe level to breathe using a demand regulator which is connected to the top of the tank.
This regulator is comprised of 2 stages, the 1st stage brings down the pressure from the tank which is around 2000 to 3000 psi. The pressure reduced air which is around 140 psi then travels down a hose to the 2nd stage which works on a demand system! This is the unit you see next to the divers mouth, the diver creates a seal around the mouth piece much like you would with a snorkel. A piston or a diaphragm holds back the air and only releases it when the diver breathes in. The used air that the diver breathes out is released through two exhaust ports. A scuba diver can spend just under a hour underwater depending on how deep he dives or conditions like water temperature and comfort level.
