The ‘risers’ are the webbing that connects your parachute container to the lines. There are four risers – two at the front and two at the back – and your toggles and steering lines are connected to the back ones.
What are the lines of a parachute?
There are the lines, which run from the parachute to the container through a pair of thick straps called the risers. Most modern parachutes have five sets of lines called the A-lines, B-lines, C-lines, D-lines and brake lines. There is the AAD, also known as the automatic activation device.
How do you steer parachutes?
The same applies to the left steering toggle. If you pull down on the left steering toggle only, the back side of the left parachute cups to create drag and induces a left turn. Additionally, risers, webbing that connect a parachute container to the lines, are another way to steer parachutes.
What does the bridle do in a parachute?
The bridle pulls the main canopy out of the container so that it can inflate. There is a second parachute, known as the reserve, that is available in case the main canopy fails for some reason. The main canopy might not come out of its container, it might not inflate properly, it might get tangled in its lines, and so on.
How do you use the rear risers to make turns?
Your toggles and steering lines are attached to the rear risers. This means you can use the rear risers to make turns as well, and in exactly the same manner as the toggles. You pull down on the right rear riser to turn right and on the left rear riser to turn left.
What are the parts of a parachute?

What is the lowest height you can pull your parachute?
When Do Skydivers Open Their Parachute?Tandem Skydivers must open parachutes by 4,500AGL (Though, most open around 5,000-5,500 to allow you to enjoy the view)Students and A License holders must open their parachutes by 3,000 feet AGL.B-License jumpers must open their parachutes by 2,500 feet AGL.More items...
How high up do you deploy a parachute?
For most licensed skydivers, the deployment altitude is 3,000 feet. Tandem skydivers usually deploy between 5,000 and 5,500 feet. There is a discipline in skydiving known as Canopy Relative Work (CReW) and this group of skydivers deploy their parachutes as soon as they exit the plane!
How do you land with rear risers?

What happens if you open a parachute too early?
While opening the parachute too early will not prevent the parachute from opening, it can be still dangerous due to the following problems: The wind drifts the skydiver away from the drop zone. There is a higher risk of collision with other skydivers or aircrafts.
How often do parachutes fail?
one in every 1,000 parachutesParachutes Properly Deploy 99.9% of the Time. Even when skydiving equipment is frequently assessed and replaced, the unexpected can happen. Even seemingly properly packed parachutes can fail, with one in every 1,000 parachutes not always operating at 100% efficiency.
How long does it take for a parachute to fully deploy?
The most important thing to do is pull the ripcord immediately. It takes approximately 2-3 seconds for the parachute to fully deploy. Altitude used for complete deployment at terminal velocity is approximately 300-500 ft.
How fast do you hit the ground when parachuting?
Terminal velocity is the fastest you'll fall during your jump; typically around 200 kph (120 mph). Your first few seconds in freefall will be a wee bit slower, so you'll cover a little less distance at first, but then you'll accelerate to full speed.
How long do you fall before opening parachute?
Based on a typical skydiving freefall descent rate (which we'll tell you about in a moment), it takes around 10 seconds to fall the first thousand feet then five seconds thereafter. So from 14,000 feet, opening your parachute around 5,000 feet, you'll fall for about fifty seconds.
What effect does pulling on the front risers have on the canopy?
Pulling down the front risers too much will not help your canopy go any more quickly; you'll only deform the canopy and make it less aerodynamic.
What is a high performance canopy maneuver?
A high performance landing is when the canopy's air speed is deliberately increased for landing. This increased speed, when achieved at the correct height above the ground, can be converted into a high speed “surf” across the ground with the canopy flying level for several metres, commonly known as a swoop.
How does wind affect the glide path of your canopy?
Look ahead to find the point on the ground that appears not to rise or sink. How does wind affect the glide path? The glide path will become steeper as the wind decreases when flying with the wind.
At what height do paratroopers jump?
between 15,000 and 35,000 feetIn typical HALO/HAHO insertions the troops jump from altitudes between 15,000 and 35,000 feet (4,600 and 10,700 m). Military parachutists will often reach a terminal velocity of 126 mph (203 km/h), allowing for a jump time under two minutes.
Is there a minimum weight for skydiving?
While there is no minimum weight requirement, the maximum weight for tandem skydiving is 230lbs. Additionally, you need to be at least eighteen years old and therefore adult-sized.
How fast do you fall with a parachute open?
120mphThe most common number associated with skydiving speed is 120mph (200kph).
What's the highest someone has skydived?
135,889 feetAlan Eustace's jump was recorded from the height of 135,889 feet (41.41 kilometers), making his the highest jump ever, topping even the Red Bull highest skydive.
Who was the first person to use a frameless parachute?
Illustration from the late 19th century. The first use of a frameless parachute, by André Garnerin in 1797. Schematic depiction of Garnerin's parachute, from an early nineteenth-century illustration.
What is a parachute in Coldplay?
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag (or in the case of ram-air parachutes, aerodynamic lift ).
How much did the Broadwick parachute weigh?
In 1911 a successful test took place with a dummy at the Eiffel tower in Paris. The puppet's weight was 75 kg (165 lb); the parachute's weight was 21 kg (46 lb).
Why are parachute numbers so difficult to estimate?
Exact numbers are difficult to estimate because parachute design, maintenance, loading, packing technique and operator experience has a significant impact on malfunction rates. Approximately one in a thousand sport main parachute openings malfunctions, requiring the use of the reserve parachute, although some skydivers have many thousands of jumps and never needed to use their reserve parachute.
How high did Kittinger jump?
He jumped from a balloon at an altitude of 102,800 feet (31,333 m) (which was also a piloted balloon altitude record at the time). A small stabilizer chute deployed successfully, and Kittinger fell for 4 minutes and 36 seconds, also setting a still-standing world record for the longest parachute free-fall, if falling with a stabilizer chute is counted as free-fall. At an altitude of 17,500 feet (5,300 m), Kittinger opened his main chute and landed safely in the New Mexico desert. The whole descent took 13 minutes and 45 seconds. During the descent, Kittinger experienced temperatures as low as −94 °F (−70 °C). In the free-fall stage, he reached a top speed of 614 mph (988 km/h or 274 m/s), or Mach 0.8.
Why is a parachutist packed?
A parachute is carefully folded, or "packed" to ensure that it will open reliably. If a parachute is not packed properly it can result in a malfunction where the main parachute fails to deploy correctly or fully. In the United States and many developed countries, emergency and reserve parachutes are packed by " riggers " who must be trained and certified according to legal standards. Sport skydivers are always trained to pack their own primary "main" parachutes.
Why was the German parachute stowed in the fuselage?
Airplane cockpits at that time also were not large enough to accommodate a pilot and a parachute, since a seat that would fit a pilot wearing a parachute would be too large for a pilot not wearing one. This is why the German type was stowed in the fuselage, rather than being of the "backpack" type. Weight was – at the very beginning – also a consideration since planes had limited load capacity. Carrying a parachute impeded performance and reduced the useful offensive and fuel load.
What is a main riser?
Main risers are considered a “weak link” between the forces your main canopy can generate and your harness. Experience has proven that main risers can break at the riser grommet if subjected to a high G-load.
Can a main riser break?
Experience has proven that main risers can break at the riser grommet if subjected to a high G-load. If the RSL connecting ring is installed above the riser grommet and that riser was to break, the reserve parachute could be deployed while the malfunctioning main parachute is still attached by the opposite riser.
Can you use a main riser on a Mirage RSL?
For this reason, main risers made by another manufacturer may not be compatible with your Mirage RSL. Only install main risers with the RSL connecting ring mounted below the 3-ring release grommet passing through the riser. If the risers were not manufactured by Mirage Systems, Inc., check to make sure that the RSL is long enough to reach ...
How many risers are there in a parachutist?
There are four risers, two front risers and two rear risers. Your toggles and steering lines are attached to the rear risers. This means you can use the rear risers to make turns as well, and in exactly the same manner as the toggles. You pull down on the right rear riser to turn right and on the left rear riser to turn left.
How does a parachute work?
The cells are open at the front of the parachute and are sealed at the back. As the parachute moves forward, air is forced into the cells, which then stiffens the “wing” and gives it shape. Much like an airplane wing, the air moves faster under the parachute than over it, which generates lift.
How do you steer a parachute?
A series of lines descend from the parachute down to the pilot. Along the back edge of the parachute, you will find the steering lines. These lines cascade down about half of the length of the line, four converging to become one on each side and ending where your hands can reach into a reinforced loop — what we call a steering toggle.
What makes skydiving so enchanting?
The ability to maneuver a man-made wing, increasing speed for a zippy ride or casually soaring about like a bird on a breeze, is what makes modern skydiving so enchanting. But this wasn’t always the case. Parachute steering has come a long way.
What was the purpose of the parachutes used in skydiving?
The parachutes used at civilian skydiving’s inception were generally surplus equipment from the military. They were dome-shaped and solely a means for increasing drag to safely deliver men and cargo to designated places.
What is the function of a parachute toggle?
In addition to steering the parachute, the toggles have another important function: flaring (slowing or stopping the forward and downward momentum of the parachute). If you want to flare a parachute, pull down evenly on both toggles at the same time.
How fast is a skydiving flight?
In skydiving, two parts make a whole. The sport’s not just composed of a swift freefall reaching speeds of 120 miles per hour. Part of the fun of any skydive is the canopy flight. With modern day parachutes, the options for your flight are downright customizable. The ability to maneuver a man-made wing, ...
How does an air parachute work?
Air enters, or rams, into the front of the canopy to inflate the cells and give the parachute an airfoil shape. This shape makes the parachute act like a wing (see How Airplanes Work for a description of wings).
What is a parachute made of?
This type of parachute is square or rectangular and is made completely out of lightweight nylon. There is a top and bottom sheet of nylon, and then a set of fabric ribs between them. The ribs divide the parachute into a set of individual cells. Air enters, or rams, into the front of the canopy to inflate the cells and give ...
Why does the bridle pull the canopy out of the container?
The bridle pulls the main canopy out of the container so that it can inflate. There is a second parachute, known as the reserve, that is available in case the main canopy fails for some reason. The main canopy might not come out of its container, it might not inflate properly, it might get tangled in its lines, and so on.
How far does the AAD release the reserve parachute?
If something goes wrong -- for example, the skydiver passes out or gets distracted -- the AAD will automatically release the reserve parachute at about 750 feet (230 meters). Just about everyone today uses ram-air canopies.
How many lines are there in a parachutist?
There are the lines, which run from the parachute to the container through a pair of thick straps called the risers. Most modern parachutes have five sets of lines called the A-lines, B-lines, C-lines, D-lines and brake lines. There is the AAD, also known as the automatic activation device.
What is the size of a pilotchute?
There is the parachute itself, also known as the main canopy. There is the pilotchute -- a small (12 to 18-inch / 30 to 45-centimeter diameter) parachute that the skydiver uses to pull out and open the main canopy. The skydiver throws out the pilot.
Can you turn a parachute to the left?
This causes the left side of the parachute to slow down, so you turn to the left. You can turn to the right in the same way. If you pull both the left and right toggles together, it slows the whole wing down and acts like a brake. This allows you to flare to a stop during landing.
Overview
Types
Today's modern parachutes are classified into two categories – ascending and descending canopies. All ascending canopies refer to paragliders, built specifically to ascend and stay aloft as long as possible. Other parachutes, including ram-air non-elliptical, are classified as descending canopies by manufacturers.
History
In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground."
The earliest evidence for the true parachute dates back to the Renaissance peri…
Deployment
Reserve parachutes usually have a ripcord deployment system, which was first designed by Theodore Moscicki, but most modern main parachutes used by sports parachutists use a form of hand-deployed pilot chute. A ripcord system pulls a closing pin (sometimes multiple pins), which releases a spring-loaded pilot chute, and opens the container; the pilot chute is then propelled into the air stream by its spring, then uses the force generated by passing air to extract a deploymen…

Records
On August 16, 1960, Joseph Kittinger, in the Excelsior III test jump, set the previous world record for the highest parachute jump. He jumped from a balloon at an altitude of 102,800 feet (31,333 m) (which was also a piloted balloon altitude record at the time). A small stabilizer chute deployed successfully, and Kittinger fell for 4 minutes and 36 seconds, also setting a still-standing world r…
Uses
In addition to the use of a parachute to slow the descent of a person or object, a drogue parachute is used to aid horizontal deceleration of a land or air vehicle, including fixed-wing aircraft and drag racers, provide stability, as to assist certain types of light aircraft in distress, tandem free-fall; and as a pilot triggering deployment of a larger parachute.
