Parachuting, also known as skydiving, is where a person jumps from enough height so that he can deploy a fabric
parachuteand land safely.
The history of parachuting appears to start with
Andre-Jacques Garnerinwho made successful parachute jumps from a hot-air balloon in 1797. The military... developed parachuting technology first as a way to save aircrews from emergencies aboard balloons and aircraft in flight, later as a way of... delivering soldiers to the battlefield. Early competitions date back to the 1930s, and it became an international sport in 1951.
Sport Parachuting is performed as a
recreational activity and a competitive sport, as well as for the deployment of military personnel Airborne forcesand occasionally forest firefighters.
In the early days, a trained skydiver (or
jumper) and a group of associates met at an isolated airport, sometimes referred to as a "drop zone." (DZ) A fixed base operatorat that airport usually operates one or more aircraft, and takes groups of skydivers up for a fee. It was common for an individual jumper to go up in a Cessnalight aircraft such as C-172or C-182. These days, it is common for busier DZs near populated areas to use multiple, larger aircraft such as the Cessna Caravan C208 or De Havilland Twin Otter DHC6.
A typical jump involves individuals jumping out of an
aircraft(usually an airplane, but sometimes a helicopteror even the gondola of a balloon), at approximately 4,000 meters (around 13,000 feet) altitude, and free-falling for a period of time before activating a parachute to slow the landingdown to safe speeds.
Once the parachute is opened, (usually the parachute will be fully inflated by 2,500 ft). the jumper can control his or her direction and speed with toggles on the end of steering lines attached to the trailing edge of the parachute, and so he or she can aim for the landing site and come to a relatively gentle stop in a safe landing environment. All modern sport parachutes are self-inflating "ram-air" wings that provide control of speed and direction similar to the related
paragliders. Purists in either sport would note that paragliders have much greater lift and range, but that parachutes are designed to absorb the stresses of deployment at terminal velocity.
By manipulating the shape of the body—as a pilot manipulates the shape of his aircraft's wings—a skydiver can generate turns, forward motion, backwards motion, and even lift (relative to other skydivers, not to the ground). Experienced skydivers say that in freefall one can do anything a bird can do, except go back up.
When leaving an aircraft, for a few seconds a skydiver continues to travel forwards as well as down, due to the momentum created by the plane's speed (known as throw-forward). The perception of a change 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 a "falling" sensation because the resistance of the air to their body at speeds above about 50 MPH provides some feeling of weight and direction. At normal exit speeds for aircraft (approx 90 MPH) there is little feeling of falling just after exit, but jumping from a balloon or helicopter can create this sensation. Skydivers reach terminal velocity (around convert|120|mi/h|km/h|-1|abbr=on for belly to Earth orientations, 150-200 mph (240-320 km/h) for head down orientations) and are no longer accelerating towards the ground. At this point the sensation is as of a hard wind.
Many skydivers make their first jump with an experienced and trained instructor (this type of skydive may be in the form of a tandem skydive). During the tandem jump the jumpmaster is responsible for the stable exit, maintaining a proper stable freefall position, and activating and controlling the parachute. With training and experience, the fear of the first few jumps is supplanted by the tact of controlling fear so that one may come to experience the satisfaction of mastering aerial skills and performing increasingly complicated maneuvers in the sky with friends. Other training methods include static line, IAD (Instructor Assisted Deployment), and AFF (Accelerated Free fall) aka Progressive Free-Fall (PFF) in Canada.
At larger dropzones, training in the sport is often conducted by full-time instructors and coaches at commercial establishments. Commercial centers often provide year-round availability, larger aircraft, and staff who are current in both their sport and their instructional skills.
In areas where winter (or
monsoons) gets in the way of year-round operation, commercial skydiving centers are less prevalent and much of the parachuting activity is carried on by clubs. These clubs tend to use smaller aircraft. Training may be offered (by instructors who are tested and certified in exactly the same way as their commercial counterparts) in occasional classes or as demand warrants. These clubs tend to be weekend only operations as the majority of the staff have full-time jobs during the week. Club members will often visit larger centers for holidays, events, and for some concentrated exposure to the latest techniques.
Parachuting has complex skills that can take thousands of jumps to master, but the basics are often fully understood and useful during the first few jumps. There are four basic areas of skill: basic safety, free fall maneuvers, parachute operation, and landing.
In freefall most skydivers start by learning to maintain a stable belly to earth "arch" position [http://www.uspa.org/publications/SIM/2008SIM/Section4CatA.htm#1b Freefall stable body position] . In this position the average fall rate is around convert|190|km/h|mi/h|-1|abbr=on. Learning a stable arch position is a basic skill essential for a reliable parachute deployment. Next, jumpers learn to move or turn in any direction while remaining belly to earth. Using these skills a group of jumpers can create sequences of formations on a single jump, a discipline formerly known as relative work (RW) and now as formation skydiving (FS). In the late 1980s more experienced jumpers started experimenting with freeflying, falling in any orientation other than belly to earth. Today many jumpers start freeflying soon after they earn their license, bypassing the traditional flat-flying stepping stone.
Parachute operation and landing
The decision of when to deploy the parachute is a matter of safety. A parachute should be deployed sufficiently high to give the parachutist time to handle a malfunction, should one occur. convert|600|m|ft|-1 is the practical minimum for advanced skydivers. [ [http://www.uspa.org/publications/SIM/2007SIM/section2.htm#21g 2007 SIM ] ] Skydivers monitor their altimeters during freefall to decide when to break off from the formation (if applicable) and when to open their parachutes. Many skydivers open higher to practice their parachute flying skills. During a "hop-and-pop," a jump in which the parachute is deployed immediately upon exiting the aircraft, it is not uncommon to be under canopy as high as 1200 to 1500 meters (4000 to 5000 ft).
Parachute flying involves two basic challenges. Firstly to avoid injury and secondly to land where planned, often on a designated target. Some experienced skydivers enjoy performing aerobatic maneuvers with parachutes, the most notable being the "Swoop". This is a thrilling, but dangerous maneuver entailing a steep, high speed landing approach, before leveling off a couple of feet above the ground to maintain a fast glide parallel to the surface. Swoops as far as convert|180|m|ft|-1 have been achieved.
A modern parachute or canopy "wing" can glide substantial distances. Elliptical canopies go faster and farther, and some small, highly loaded canopies glide faster than it is possible to run, which can make them very challenging to land. A highly experienced skydiver using a very small canopy can achieve over convert|100|km/h|mi/h|-1|abbr=on horizontal speeds in landing.
Today, the majority of skydiving related injuries and deaths happen under a fully opened and functioning parachute. The most common cause being poorly-executed, radical maneuvers near to the ground, such as hook turns, or landing flares performed either too high or too low.
Despite the perception of danger, fatalities are rare. However, each year a number of people are hurt or killed parachuting world-wide. [cite web|url=http://www.skydivingfatalities.info/|title=Fatality statistics] [cite web|url=http://www.dropzone.com/fatalities/|title=dropzone.com statistics] About 30 skydivers are killed each year in the US; roughly one death for every 100,000 jumps. [cite web|url=http://stuffo.howstuffworks.com/skydiving8.htm|title=How skydiving works]
In the US and in most of the western world skydivers are required to carry two parachutes. The reserve parachute must be periodically inspected and re-packed (whether used or not) by a certificated parachute rigger (in the US, an FAA certificated parachute rigger). Many skydivers use an
automatic activation device(AAD) that opens the reserve parachute at a safe altitude in the event of failing to activate the main canopy themselves. Most skydivers wear a visual altimeter, but increasingly many also use audible altimeters fitted to their helmet.
Injuries and fatalities occuring under a fully functional parachute usually happen because the skydiver performed unsafe maneuvers or made an error in judgement while flying their canopy, typically resulting in a high speed impact with the ground or other hazards on the ground.Fact|date=July 2008 In recent years, one of the most common sources of injury is a low turn under a high-performance canopy and while swooping. Swooping is the advanced discipline of gliding parallel to the ground during landing. Changing wind conditions are another risk factor. In conditions of strong winds, and turbulence during hot days the parachutist can be caught in downdrafts close to the ground. Shifting winds can cause a crosswind or downwind landing which have a higher potential for injury due to the wind speed adding to the landing speed.
Equipment failure rarely causes fatalities and injuries. Exact numbers are difficult to estimate but approximately one in a thousand deployments of a main parachute results in a malfunction, although some skydivers have many thousands of jumps and never experience a malfunction (either they pack their mains more carefully than average or they are just lucky). Ram-air parachutes typically spin uncontrollably when malfunctioned, and must be jettisoned before deploying the reserve parachute. Reserve parachutes are packed and deployed differently, they are also designed more conservatively and built & tested to more exacting standards so they are more reliable than main parachutes, but the real safety advantage comes from the probability of an unlikely main malfunction multiplied by the even less likely probability of a reserve malfunction. This yields an even smaller probability of a double malfunction although the possibility of a main malfunction that cannot be cutaway causing a reserve malfunction is avery real risk.
Parachuting disciplines such as
BASE jumpingor those that involve equipment such as wing suit flying and sky surfing have a higher risk factor due to the lower mobility of the jumper and the greater risk of entanglement. For this reason these disciplines are generally practiced by experienced jumpers.
It is worth noting that depictions in commercial films — notably
Hollywoodaction movies — usually overstate the dangers of the sport. Often, the characters in such films are shown performing feats that are physically impossible without special effectsassistance. In other cases, their practices would cause them to be grounded or shunned at any safety-conscious drop zoneor club. USPA member drop zones in the US and Canada are required to 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 the jumpers who violate rules, regulations, or otherwise act in a fashion deemed unsafe by the appointed individual.
In many countries, either the local regulations or the liability-conscious prudence of the dropzone owners require that parachutists must have attained the
age of majoritybefore engaging in the sport.
Parachuting and weather
Parachuting in poor weather, especially with thunderstorms, high winds, and dust devils can be a dangerous activity.
There are several different disciplines to embrace within parachuting. Each of these is enjoyed by both the recreational (weekend) and the competitive participants. There is even a small group of
professionals who earn their living with parachuting. They win competitions having cash prizes or are employed or sponsored by skydiving related manufacturers.
Parachutists can participate both in competitive and in purely recreational skydiving events. World championships are held regularly in locations offering flat terrain and clear skies. An exception is Paraski, where winter weather and ski-hill terrain are required.
Types of parachuting include:
Accuracy landing- Landing as close as possible to a target.
BASE jumping- From buildings, antennas, bridges (spans) and cliffs (earth).
Blade running- A kind of slalom with a parachute.
Big-ways- Formation skydiving with many people all falling belly to earth.
Canopy formation- Making formations with other parachutists while under canopies. (Known also as canopy relative work or simply CRW (CRew))
Canopy piloting- Also known as 'swooping'.
Formation skydiving- Making formations during freefall. (Known also as relative work or simply deployment-position RW)
Freeflying- Flying in multiple orientations (i.e. head down, flocking, and sitflying). A more advanced approach to skydiving.
* Military Parachuting
Skysurfing- Skydiving with a board strapped to one's feet.
Vertical Formation Skydiving- a subset of Formation skydivingthat uses high-speed freeflyingbody positions instead of bellyflying. (Known also as VRW)
Wingsuit flying- Skydiving with a suit which provides extra lift, and powered skydivingwhere the wingsuit flyer adds propulsion.
There are ways to practice different aspects of skydiving, without actually jumping.
Vertical wind tunnels can be used to practice skills for free fall ("indoor skydiving" or "bodyflight"), while virtual realityparachute simulators can be used to practice parachutecontrol.
Beginning skydivers seeking training have a few different options available to them:
Instructor Assisted Deployment
A unique program where students accomplish their very first jump as a solo freefall is offered at the
United States Air Force Academy. The program is called AM490, one in a series of airmanship courses at the school. While typically open only to cadets, Winfield W. Scott Jr., the school's superintendent, went through this program when he was nearly 60 years old.
At a skydiver's designated deployment altitude, the individual manually deploys a small pilot-chute which acts as a drogue, catching air and pulling out the main parachute. There are two principal systems in use : the "throwaway", where the skydiver pulls a toggle attached to the top of the pilot-chute stowed in a small pocket outside the main container : and the "pull-out", where the skydiver pulls a small pad attached to the pilot-chute which is stowed inside the container. Throwaway pilot-chute pouches are nowadays usually positioned at the bottom of the container - the B.O.C. deployment system - but older harnesses often have leg-mounted pouches. The latter are safe for flat-flying, but unsuitable for freestyle or head-down flying.
The pilot-chute is connected to a line known as the "bridle", in turn attached to a small deployment bag which has the folded parachute inside and the lines stowed in rubber bands across the top. At the bottom of the container which holds the main parachute is a fabric loop which, during packing, is fed through grommets on each of four flaps that close the container.
Attached to the bridle is a curved pin which is inserted through the closing loop after it has been fed through each of these grommets. When the pilotchute is thrown out, it catches the wind and pulls the pin out of the closing loop, allowing the pilot-chute to pull the deployment bag from the container. The parachute lines are pulled loose from rubber bands, through which they were stowed during packing, and extend as the canopy starts to open. A rectangular piece of fabric called the "slider" (which separates the parachute lines into four main groups fed through grommets in the four respective corners of the slider) slows the opening of the parachute and works its way down until the canopy is fully open and the slider is just above the head of the skydiver. The slider slows and controls the deployment of the parachute. Without a slider the parachute would inflate violently fast and the parachute would be destroyed by the wind drag/rapid deceleration. During a normal deployment, a skydiver will generallyexperience a few seconds of intense deceleration, in the realm of 3 to 4 G's, while the parachute slows the descent from convert|120|mi/h|km/h|-1|abbr=on to approximately convert|12|mi/h|km/h|0|abbr=on.
If a skydiver experiences a malfunction of their main parachute which they cannot correct, they pull a "cut-away" handle on the front right-hand side of their harness (on the chest) which will release the main canopy from the harness/container. Once free from the malfunctioning main canopy, the reserve canopy can be activated manually by pulling a second handle on the front left harness. Some containers are fitted with a connecting line from the main to reserve parachutes - known as a Reserve Static Line (RSL) - which pulls opens the reserve container faster than a manual release could. Whichever method is used, a spring loaded pilotchute then extracts the reserve parachute from the upper half of the container.
In addition to the various disciplines, for which people actually train, purchase specialized equipment and get coaching, the recreational skydiver finds ways to just have fun.
Hit and rock
One example of this is "Hit and Rock", which is a variant of
Accuracy landingdevised to let people of varying skill levels "compete" for fun, while spoofing the age and abilities of some participants. "Hit and Rock" is originally from POPS (Parachutists Over Phorty Society). See the [http://www.thepops.org POPS main site]
The object now becomes: to land as close as possible to the chair, remove the parachute harness, sprint to the chair, sit fully in the chair and rock back and forth at least one time. The contestant is timed from the moment that feet touch the ground until that first rock is completed. This event is considered a race.
Pond swooping is a form of competitive parachuting wherein canopy pilots attempt to touch down at a glide across a small body of water, and onto the shore. Events provide lighthearted competition, rating accuracy, speed, distance and style. Points and peer approval are reduced when a participant "chows", or fails to reach shore and sinks into the water.
woop and Chug the Beer
Very similar to Hit and Rock, except the target is replaced by a case of beer. Each jumper is timed from the moment his feet touch the ground until he "chugs", or rapidly drinks the can of beer and places the empty can upside-down on his head.
Of course, it must be mentioned that dropzones enforce strict rules prohibiting anyone from jumping any more that day once alcohol has been consumed. Therefore, the Swoop & Chug (aka Hit & Chug) is usually reserved for the last load of the day.
cross-country jumprefers to a skydive where the participants open their parachutes immediately after jumping, with the intention of covering as much ground under canopy as possible. Usual distance from Jump Run to the dropzone is convert|10|mi|km|-1.
In camera flying, a cameraman or camerawoman jumps with other skydivers and films them. The camera flyer often wears specialized equipment, such as a winged jumpsuit to provide a greater range of fallrates, helmet-mounted video and still cameras, mouth operated camera switches, and special optical sights. Some skydivers specialize in camera flying and a few earn significant fees for filming students on coached jumps or tandem-jumpers, or producing professional footage and photographs for the media.
There is always a demand for good camera flyers in the skydiving community, as many of the competitive skydiving disciplines are judged from a video record.
Skydiving is not always restricted to daytime hours. Experienced skydivers sometimes perform night jumps. For obvious safety reasons, this requires more equipment than a usual daytime jump and in most jurisdictions requires both an advanced skydiving license (at least a B-License in the U.S.) and specialized training (night rating). A lighted altimeter (preferably accompanied with an audible altimeter) is a must. Skydivers performing night jumps often take flashlights up with them so that they can check their canopies once they deploy, so they can be assured that the canopy has opened correctly and is safe to fly and land. Visibility to other skydivers and other aircraft is also a consideration; FAA regulations require skydivers jumping at night to be wearing a light visible for three miles (5 km) in every direction, and to turn it on once they are under canopy. A chemlight(glowstick) is a good idea on a night jump.Night jumpers should be made aware of the Dark Zone, when landing at night. Above 100 feet jumpers flying their canopy have a good view of the landing zone normally because of reflected ambient light/moon light. Once they get close to the ground, this ambient light source is lost, because of the low angle of reflection. The lower they get, the darker the ground looks. At about 100 feet and below it may seem that they are landing in a black hole. All the sudden it gets real dark and the next thing they know, there is the ground. This ground rush should be explained and anticipated for the first time night jumper.
Skydivers are always looking for something new to do in the air. With the availability of a rear door aircraft and a large, unpopulated space to jump over, 'stuff' jumps become possible. In these jumps the skydivers jump out with some object. Rubber raft jumps are popular, where the jumpers sit in a rubber raft. Cars, bikes, motorcycles, hoovers, water tanks and inflatable companions have also been thrown out the back of an aircraft. At a certain height the jumpers break off from the object and deploy their parachutes, leaving it to smash into the ground at a very high speed.
National parachuting associations exist in many countries (many affiliated with the
Fédération Aéronautique Internationale(FAI)), to promote their sport. In most cases, national representative bodies, as well as prudent local dropzone operators, require that participants carry certification, attesting to their training, their level of experience in the sport, and their proven competence. Anyone who cannot produce such bona-fides is treated as a student, requiring close supervision.
The primary organization in the United States is the
United States Parachute Association(USPA) [http://www.uspa.org] . This organization hands out licenses and ratings for all American skydiving activities based on safety qualifications. The USPA governs safety in the sport of skydiving as this is the organizations sole responsibility and also publishes the Skydivers Information Manual (SIM) and many other resources. In Canada, the Canadian Sport Parachuting Associationis the lead organization. In South Africathe sport is managed by the Parachute Association of South Africa, and in the United Kingdomby the British Parachute Association.
First Sports Parachute club in Ohio was established at Green County Airport near Xenia.Vintage sky diving video 1950s http://video.google.com/videoplay?docid=5280144247276925002&hl=en
Within the sport, associations promote safety, technical advances, training-and-certification, competition and other interests of their members. Outside their respective communities, they promote their sport to the public, and often intercede with government regulators.
Competitions are organized at regional, national and international levels in most these disciplines. Some of them offer amateur competition. Many of the more photogenic/videogenic variants also enjoy sponsored events with prize money for the winners.
The majority of jumpers tend to be non-competitive, enjoying the opportunity to "get some air" with their friends on weekends and holidays. The atmosphere of their gatherings is relaxed, sociable and welcoming to newcomers. Party events, called "boogies" are arranged at local, national and international scale, each year, attracting both the enthusiastic young jumpers and many of their elders - Parachutists Over Phorty (POPs), Skydivers Over Sixty (SOS) and even older groups who have yet to choose a catchy name for themselves.Famous people associated with this sport include Valery Rozov, a gold medalist from the 1998 X Games, who has had more than 1,500 jumps. Georgia Thompson ("Tiny") Broadwick is one of the first American skydivers, and she made the first freefall.
In parachuting, a drop zone or DZ is the area above and around a location where a parachutist freefalls and expects to land. It is usually situated beside a small airport, often sharing the facility with other
There is generally a landing area designated specifically for parachute landings. Drop zone staff include the DZO (drop zone operator or owner), manifestors, pilots, instructors, coaches, cameramen, packers, riggers and other general staff.
Costs in the sport are not trivial. As new technological advances or performance enhancements are introduced, they tend to nudge equipment prices higher. Similarly, the average skydiver carries more equipment than in earlier years, with safety devices (such as an Reserve static line) contributing a significant portion of the cost. A full set of brand-new equipment can easily cost as much as a new motorcycle or half a small car. The market is not large enough to permit the commoditization and price-erosion that is seen in other technologically intensive industries (like the computer industry).
In many countries, the sport supports a substantial used-equipment market. For many beginners, especially those with limited funds, that is the preferred way to acquire "gear", and has two advantages:
* First, they can try different types of parachutes (there are many) to learn which style they prefer, before paying the price for new equipment.
* Second, they can acquire a complete system and all the peripheral items in a short time and at reduced cost.
Novices generally start with parachutes that are large and docile relative to the jumper's body-weight. As they improve in skill and confidence, it is customary to graduate to smaller, faster, more responsive parachutes. An active jumper might change parachute canopies several times in the space of a few years, while retaining his or her first harness/container and peripheral equipment.
Older jumpers, especially those who jump only on weekends in summer, sometimes tend in the other direction, selecting slightly larger, more gentle parachutes that do not demand youthful intensity and reflexes on each jump. They may be adhering to the maxim that: "There are old jumpers and there are bold jumpers, but there are no old, bold jumpers."
Most parachuting equipment is ruggedly designed and is enjoyed by several owners before being retired. Purchasers are always advised to have any potential purchases examined by a qualified parachute rigger. A rigger is trained to spot signs of damage or misuse. Riggers also keep track of industry product and safety bulletins, and can therefore determine if a piece of equipment is up-to-date and serviceable.
