WARNING!
Each time you use this parachute you risk serious bodily injury or death.
You can substantially reduce this risk by:
1) assuring that every component of the parachute system has been assembled and packed in
strict compliance with the manufacturer’s instructions
2) by obtaining proper instruction in the use of this canopy and the rest of your equipment
3) and by operating each component of the system in strict compliance with the owner’s
manual and safe parachuting practices.
However, parachute systems sometimes fail to operate properly - even when properly
assembled, packed and operated - so you risk serious injury or death each time you use the
system.
About This Manual
It is beyond the scope of this manual to teach you how to deploy, fly, land or maintain
parachute.
The Czech Aeroclub publishes recommended procedures on learning to jump and using
skydiving equipment. We urge you to learn and follow these procedures. We also recommend
you obtain instruction from a competent rated instructor before using this parachute for the first
time.
Other countries have similar organizations for instruction. If you are not in the Czech republic
get instruction from a competent instructor that is rated by your country’s organization.
Jumping this parachute without first receiving thorough and personal instruction increases the
serious injury or death.
Sport parachuting technology and procedures continue to advance rapidly. Although
reasonable care has been made in the preparation of this manual, Jojowings cautions that it may
contain information that may be incorrect or behind the current state-of-the-art parachute use.
For these reasons, we urge you to work closely with qualified experts - riggers and instructors - to
help you inspect, assemble, pack, use and maintain this parachute.
We also welcome your comments, good or bad, about our products.

Read Before Assembly or Use
Since parachutes are manufactured and inspected by people, there is always a possibly this
parachute contains defects as a result of human error. Therefore, the entire parachute system -
main and reserve canopies, harness, container, and other components - must be thoroughly
inspected before their first use and before each subsequent use.
Parachutes get weaker through time for a number of reasons. They receive wear during
packing, deployment and landing. Exposure to many agents, including sunlight, heat and
household chemicals, significantly weakens parachutes. The damage may or may not be obvious.
To help minimize the risk of parachute failure and possible serious injury or death, the entire
parachute system should be thoroughly inspected at least every 120 days or 50 jumps, whichever
comes first. It should be immediately inspected if at any time it is exposed to a degrading
element, unusually hard opening, or any time damage may be suspected.
Remember that some chemicals will continue to degrade the parachute long after initial
exposure. Regular and thorough inspections are necessary to insure the structural integrity,
reliability, and flight characteristics of the system are maintained.
Always know the entire life history of every part of your parachute system. That way you’ll
know no part has been exposed to an element that may seriously weaken or damage it.

Picking The Right Canopy
It is important for your safety and enjoyment that you match your canopy with your ability and
weight. Jojowings canopies are built in several models that span a wide range of canopy surface
area. Any canopy’s descent rate and forward speed increases as the weight it is carrying - the so-
called suspended weight - increases. The canopy also becomes more responsive as forward speed
increases. It also reacts more radically when it is stalled or tuned.
Because of these aerodynamic facts, it is unsafe to put too much weight under any particular
canopy. Safe and comfortable landings will be difficult to obtain, even for experienced jumpers
under ideal conditions. Less experienced jumpers will have even a harder time and be at greater
risk.
Determining the wing loading of the parachute you intent to jump or buy is a good guide to
matching your weight to a particular canopy.
Wing loading is easily calculated by dividing the total suspended weight in pounds by the surface
area of the canopy in square feet. Total suspended weight is the weight of the jumper plus all his
clothing and gear- including the main parachute itself.
The surface area of Jojowings canopies is printed on the data panel, on the center cell rib, or
on the center cell top surface near the tail. (Be sure to actually check the data panel - canopies of
different sizes may look the same.) A typical ready-to-jump sport piggyback (rig and both
canopies) weighs 20 to 30 lb. Add this, plus the weight of your jumpsuit, clothing and accessories
to your bodyweight to get the total suspended weight. For example, a jumper who weighs 165 lb.
with his jumpsuit on and who jumps a packed rig that weighs 25 lb. Would have a suspended
weight of 190 lb.
Here’s an example of how to calculate wing loading of a 210 sq. ft. canopy and the jumper
used in the example above: 190 lb./210 sq.ft ‘ 0.9 lb./sq.ft.
Calculate the wing loading now for the canopy you intend to jump.
If this figure is below 0.7 and 1.0 it will turn fast and go fast. It will require skill to land well in
many weather conditions or at high altitudes. Be sure your skill level is up to the demands of this
situation. If the wing loading is greater than 1.0 lb./sq.ft. you are exposing your self to a
dangerous situation. Turn rates, forward speed and rate of descent will all be very high. Control
range may be short with stalls happening very abruptly with little warning. Normal landing
techniques may not work. Extra speed on approach to landing may be required to get enough
flare to stop your rate of descent. Therefore, a front riser approach to hook turn may be required,
either of which are very dangerous.
Jojowings does not recommend that anyone jump a canopy that will result in the wing loading
exceeding 1.0 lb./sq.ft.
It also is useful to compare the wing loading of a canopy you intent to jump with the wing
loading values of parachutes you’ve been jumping. If the different is great, you should expect the
new canopy to perform very differently than the ones you’ve jumped before.

A Note About Slope Soaring
Parachutes were frequently used for slope soaring or paragliding in the past. While this is an
acceptable use, it can be very dangerous. The following guidelines will reduce the danger:
1) Obtain competent instructor before atempting any slope soaring. Many countries have
organization that certify instructors.
2) Know the site. Never be the first one to launch at a site. Talk to several people who have
used the site before under similar weather conditions. Make sure the site is free of
turbulence. Turbulence may collapse your canopy and you may fall all the way to the
ground, causing severe injury or death.
3) Know the limitations of your canopy. Glide ratios, minimum sink rate, launch speed, flight
speed, tolerance to turbulence and recovery characteristics are just some of the things
you need to know. These all vary according to wing loading, jumper weight, and canopy
type. You must be very familiar with this canopy before attempting any paragliding.
Canopies designed specifically for paragliding may perform much better than this
canopy. Therefore, do not judge the suitability of a site based on the performance of a
paraglider.
4) Make sure that you can make the landing area before you launch. Check the flight path or
obstacles. Don’t launch if there are any dangerous obstacles along your flight path.
5) Inspect your parachute frequently and thoroughly. In skydiving the jumper structurally tests
his parachute every time he deploys it. If there is any structural deficiency the opening
shock will normally cause failure at an altitude where he can safely deploy his reserve. A
slope soaring pilot is not so fortunate. Turbulence can collapse a canopy and the
subsequent opening shock can be hard enough to cause a failure. This could happen at an
altitude that is too low for the reserve to work.
6) We recommend you use a reserve designed specifically for paragliding. Because
paragliding reserves are frequently required to work at very low altitudes, a skydiving
reserve is not adequate.

Assembly
Your canopy should be assembled by a properly certified rigger. Before you begin, be sure the
risers, toggles, bridle, deployment bag, pilot chute, harness, container and
other items are compatible with your SONIC canopy and each other.
Some toggles, for example will not work properly on certain type of risers.
Assemble your system in accordance with the owner´s manual for your rig.
The instructions below are for attaching toggles that have a grommet in the center to canopies
with Vectran lines. If another type of toggle is used consult the container manufacturer for
proper installation.
Two common problems that may happen if the toggles are installed improperly are
a) the toggle knot getting caught on the guide ring and,
b) the knot slipping
Be sure that your installation is safe. The container manufacturers instructions may not be
compatible with this canopy.
Periodic Inspection Procedure
(Performed at assembly and after every 50 jumps or 120 days, whichever comes first.)
As mentioned above, your Sonic canopy must be inspected thoroughly before it is jumped the
first time and periodically thereafter. This procedure is more thorough than the inspection which
should be completed each time the parachute is packed.
You or your rigger should inspect your parachute system in a clean, well-lighted area that will
allow you to spread the main canopy out.
