Section 2: Introducin Atair
www.AtairCanopies.com or www.BaseTroll.com
Atair was foun e in 1992 by Stane Krajnc an his wife Mag alena in Slovenia. With a strong
backgroun in paragli ing esign, Atair was forme to supply the paragli ing in ustry with
reserve canopies. With a strong passion for both paragli ing an sky iving, Atair naturally
e icate their resources to eveloping new technological a vances in Sky iving an BASE
canopies. To ate Atair has manufacture over 12,000 roun s an over 10,000 sky iving an
BASE canopies.
Stane Krajnc, the owner of Atair, has been involve in air sports for the past 50 years. In 1973
Stane esigne , constructe an flew his own hang gli er. He has now accumulate
thousan s of hours on hang gli ers & paragli ers an is an expert sky iver & BASE jumper.
In 2012 An rej Krajnc, Stane's son, has taken over the reigns at Atair, allowing his father to
enjoy his retirement. An rej is a gra uate in aeronautic engineering an like his father is an
expert in all mo ern air sports.
Atair has also been involve in many special projects over the years, examples inclu e:
Specialise large canopies for cargo applications,
Drag chute for spee ski worl recor ,
Special low gli e ratio canopy for a cave BASE jump.

A Decade of feedback
The original OSP release in 2007 re efine the BASE canopy market with numerous
revolutionary features to improve the opening an flight characteristics - known for its reliable
fast openings, precise control, unparallele eep brake han ling an powerful flare. Now it is
time for an up ate incorporating the latest esign innovations, the OSP2.
The OSP2 is an all-roun BASE canopy that brings joy to sli er up an excels for sli er own.
(slow sli er recommen e for terminal jumps).
In detail:
For BASE jumping it is esirable to minimize the forwar spee upon eployment, allowing
more time for object avoi ance.
A steeper escent on the or er of one to one is esirable as for sli er own jumps the lan ing
area is generally un erneath or close to the object. Thus not only is a low forwar spee
beneficial, but a low escent rate also.
The canopy profile of the OSP2 has been specially selecte to enable steep lan ing
approaches, generating high lift even when the flow is partially separate .

Improved lide:
We have refreshe the esign retaining all the great features of the original OSP whilst
improving the performance envelope.
The OSP2 has a similar horizontal spee as the original OSP an improve gli e.
As stan ar the OSP2 retains the MDV5 , ZP lea ing e ge with SLATS an mini stabilizers
from the OSP1.
Better performance:
The ZP leadin ed e desi n has been improve using the same split panel technique as
seen on the Vision, re ucing the sink rate an increasing performance.
The bridle attachment point is move further back, so that the tension from the PC is applie
to all the lines uring opening, instea of just the AB lines, this improves the behavior of the
eploying canopy an helps re uce the chance of tension knots.
Fine tunin :
Th e tail pocket desi n has been improve to re uce weight. The brake lines are now
continuous without loops at the casca es an this also helps re uce the risk of tension knots.
The brake settings are now ma e from Spectra insert loops to improve urability, helping the
lower brake lines to last longer.
MDV technolo y:
Atair has always been at the cutting e ge of parachute esign an technology, as
emonstrate with the intro uction of numerous innovations such as the Mono Directional
Valve (MDV) technology. MDV is a unique esign that allows the air to flow into the canopy via
bottom skin vents uring the eployment stage an also uring eep brake escent. In normal
flight, the vents stay close an o not isturb the internal airflow insi e the canopy.
A canopy with MDV offers a itional performance by increasing the canopy flight envelope in
eep brakes, before reaching the stall. The canopy still has a great flare when equippe with
MDV. When making a jump with the sli er up, the canopy will inflate a bit faster than normal,
but the true benefits of MDV technology are fully exploite on sli er own jumps. The Atair
MDV system also has a very low packing volume. During eployment, MDV technology
provi es superior canopy pressurization, re ucing the amount of altitu e require for canopy
inflation an allowing the jumper almost imme iate control of the canopy.

Slat:
The SLAT system is use to increase the maximum lift coefficient an re uce stall spee .
Slats are small lea ing e ge airfoil extensions that are forming a slot at the first 10% of the
lea ing e ge. Part of the air that is entering the cell is irecte through the slot back to the
upper si e of the canopy, spee ing up the airflow an resulting in elaye separation of the
airflow, allowing the canopy to maintain lift at lower spee s an a higher angle of attack before
reaching the stall, an also re ucing vertical spee . The SLATs are applie to the lea ing
e ge of cells #3, #4 an #5, because on rectangular platform wings, the stall occurs first at the
mi le of the span, i.e. on the center cells.
The SLAT system provi es:
Re uction of canopy forwar spee uring the opening stage, allowing more time to
correct your hea ing with the risers uring low altitu e jumps in close proximity to the
objects.
Improve eep brakes flight, with crisp toggle response an re uce canopy inertia
uring steep approaches, enabling easy an accurate, on the spot lan ings in
constricte areas.
Atair was the first manufacturer to intro uce this technology on BASE canopies in 2007.

Built on the OSP:
The Vision is the ultimate all-roun canopy for experience BASE jumpers, whether it be
urban sli er own or alpine sli er up, tracking or wingsuit flying.
The Vision is built on the foun ations lai by its ol er brother, the famous OSP, which became
the stan ar upon which all other BASE canopies are measure .
A level up:
The Vision retains many characteristics of the OSP, like excellent openings an superb flight
characteristics in eep brakes, but in the area of forwar spee , gli e an flare the VISION is
taking things to a new level.
The Vision canopy is equippe with the MDV5 system stan ar , provi ing reliable, efficient
an comfortable on hea ing openings, sli er up or sli er own. For sli er up, tracking an
wingsuit jumps we recommen the use of a slow sli er

A new airfoil:
T h e Vision has expan e the performance envelope at both en s of the curve. It is
unbelievably stable in calm or turbulent win con itions in all flight regimes, thanks to a new
airfoil, improve split ZP lea ing e ge, optimize line trim an mini stabilizers in the center of
the canopy.
The bri le attachment point is move further back, so that the tension from the PC is applie to
all the lines uring opening, instea of just the AB lines, this improves the behavior of the
eploying canopy an helps re uce the chance of tension knots.
Predictable, Safe, Reliable:
The Vision has the ability to maintain a very steep an stable trajectory in eep
brakes into tight lan ing areas with plenty of lift available for a soft lan ing. This is achieve by
the use of SLAT Technology on the canopy lea ing e ge. Atair was the first parachute
manufacturer to use slats with the intro uction of the OSP canopy back in 2007.
Overall the han ling is similar to a sports sky iving canopy, but still retaining the pre ictability,
safety an reliability of a BASE canopy. Increase forwar spee an improve gli e allow you
to reach istant lan ing areas. Toggle turns are fast, responsive an efficient. Recovery from
stall to full rive is quick with minimal altitu e loss. The canopy is responsive an powerful in
front riser turns, a pleasure to swoop, with plenty of power for a great flare at the en .

List of Components
Canopy an lines
Tail Gate (BR) an rubber ban s 1 1/4“ by 1 3/16“ (3.2 cm by 0.5cm)
#5 Stainless Steel Links OR Soft links (Slinks)

Line & Riser Continuity
Left Rear Left Front Right Front Right Rear
Remember that each connector link has to show continuity from the lines to the canopy. Check
each one for proper assembly.
Each of the links will have four casca ing lines. The two control lines each casca e into four
upper brake lines.
Once you have orientate the lines properly on the #5 links, inspect them. Finger-tighten all 4
connector links. Then apply a 1/8 turn with a 9mm wrench. Do not over tighten as this can strip
or crack the link an cause it to fail. Sli e the sli er bumpers (covers) over the links.

OSP2 / Vision / VisionWS Canopy User Manual
Section 6: Recommended Drills for first fli ht
Atair stron ly recommends you perform some sky ives with your new canopy before using it
in the BASE environment.
To o this we recommen installing a slow sli er or similar size 'sail' sky iving sli er an
packing the canopy into a large sky iving container (as use for stu ent sky ivers).
Perform a hop ‘n pop from a suitable legal altitu e (with clearance from the ropzone). A short
delay to clear the aircraft and stabilise is sufficient.
During the flight, try the following rills:
Gra ual flare to locate stall point
Full flare to simulate lan ing
Full stall an recovery by slowing an equally releasing brakes
Flare from half brakes
Flare from eep brakes
Full toggle turns
Elevation turns (in brake flight release one toggle slightly to turn)
Half brake turns
Deep brake turns
Rear riser turns
Front riser turns
Check length of brake line between cats eye an toggle, are you getting a full flare
when you bring your han s to waist level?
Sharp 180º turn using alternate rear risers (simulating 180º off hea ing rill)
Remember to pay attention to your altitude and position relative to the landin area.
Atair also a vises you to tune your brake settings by making subsequent sky ives on the
canopy.
To make a justments to the brake settings, mark the stall point on the brake lines at the level
of the gui e ring using a marker pen. Consult an experience rigger when a justing the
position of the eep brake an normal brake setting position.
If the length of brake line between the brake setting an toggle is too long take a wrap of line
aroun your han an estimate how much the toggle attachment point shoul be shortene ;
again consult an experience rigger when a justing the position of the toggle attachment.

Section 7: Packin your Canopy
Before you begin this section, please rea the entire manual. If there is any element that you
on’t un erstan , please contact us or a qualifie rigger to help you with the assembly.
Ensure that you have correctly assemble the canopy onto the risers (see section 5) an that
you have proper line continuity. Be certain to secure the container so that it oes not move
uring the packing process. Make sure that the risers are even an remain even at all times.
The first packing metho to be escribe is without sli er or sli er own. Make certain that the
control lines go irectly from the toggle to the outsi e of the canopy without passing through
anything. Make sure the toggles are attache to the control lines correctly (see section 8).
If the container you are using oes not have a sli er retainer you must use a suitable material
to fix the sli er in place, consult your local rigger if you have any oubts. The other alternative
is to completely remove the sli er by releasing each connector link in turn using a spanner: this
is time consuming an there is a risk of re-connecting the lines in the incorrect manner.
Fi ure 1a Fi ure 1b
Figure1a: To start of the pack job you shoul perform a PRO (Proper Ram-Air Orientation)
pack job. Flake the canopy in a tra itional pro pack manner. Before you bring the tail aroun ,
count the three nose cells on one si e an bring the tail aroun behin them. In other wor s
o not cocoon the tail aroun the nose. Leave the nose cells expose .
Do the same on the other si e, leaving the center cell to hang own in the mi le. Gently place
the canopy on the groun , keeping tension on the lines. The neater you place the canopy, the
easier it will be to re ress it once it’s on the groun . Fin the three nose cells on each si e an
tease them out gently. They shoul be resting neatly on top of one another, resembling figure
1b above.

Figure 2: Pick a si e to start re ressing. From the bottom stabiliser, reach in between the A
an B lines an flake all of the fabric to the outsi e, keeping the lines or erly in the center.
From the next stabilizer, reach between the B an C lines, flaking all of the fabric to the
outsi e, keeping the lines or erly in the center. Now reach in between the C an D lines,
flaking all of the fabric to the outsi e, keeping the lines or erly in the center.
Be certain to maintain tension on the lines by gently pulling the appropriate fabric from the top
of the canopy uring this process. Next, be sure to clear the fabric between the D lines an the
control lines. This is one by placing your han between the D lines an the control lines an
pulling away from the container. This will remove the slack in the fabric between these two
points. Repeat all of this on the other si e an re ress by lifting the tail up so that the lines are
expose . From either si e, you can ensure that the fabric is all pulle away from the container
an that the stabilizers are clear of the lines as well. During this process, be sure to keep
tension on the lines. Ensure that the pack job is symmetrical by looking at the line attachment
points on each si e an making certain they are even.
To flake the tail, grasp the small portion of stabilizer between the D an tail on one si e an
pull the fabric outwar keeping the seam in the center an going straight up an own. This
shoul place the outer upper control line to the center. Continue by stacking all of the seam to
the tail in the center, pulling the fabric out an away from the center. Use the seams as a
gui e. These will be half-cell fol s. Continue all the way across an inclu e the center cell tail
pocket. Remember, not every fol will incorporate a control line. Do this on both si es until all
seams are on top of one another an in the center. Make certain that the canopy is completely
symmetrical at this time.

Fi ure 3: Dia ram showin lines included in Tail Gate
The Tale Gate (BR) reefing evice is use to help re uce brake line malfunctions uring sli er
own (or off) jumps. The Tail Gate helps keep the lines in the center of the canopy uring
eployment, re ucing the risk of a line over; the lines inclu e in the Tail Gate are shown in
the iagram above.
Refer to figures 3a an 3b. The slot for the Tail Gate is on one of the center C lines
approximately 4” own from line attachment tab. Fin this slot an place the Tail Gate into it.
When utilizing the Tail Gate, you shoul use a rubber ban 1 1/4 inches by 1 3/16 inch (3.2 cm by
0.5cm). Some people like to lark’s hea the rubber ban to the Tail Gate. Using the lark’s hea
is not recommen e for extreme low-spee eployments as it coul cause a hang up in
release of the Tail Gate.
