Introduction
Advice Caution ! Danger !!
Welcome to tandem flying : a world of shared passion in comfort and security.
Your SORA tandem is a glider which meets all the requirements of a modern tandem
wing. It is designed for intensive professional use and will give both the pilot and his
passengers a high level of in-flight comfort over the seasons. The construction tech-
niques and materials were selected with longevity very much in mind.
Your SORA is certified EN / LTF B. It may be used with most models of harnesses avai-
lable on the market but for better comfort and optimal feeling we recommend that
you use a pilot and passenger harness from the SUP’AIR range.
After reading this manual we advise you to inflate & check your wing on a training hill
first.

Connecting the glider
Connecting to spreaders
The bottom loop on the risers must be connected to the attachment points on the
spreaders, using karabiners with appropriate resistance for a tandem load. You must
ensure that the A risers are on top, without any twists or obstruction.
NEVER connect the glider to any other point.
The pilot then connects his harness to the rear loops on the spreaders and connects his
passenger’s harness to the forward loops.
For the connection between the glider and spreaders, we recommend SUP'AIR 45mm
steel karabiners.

Brake line length
Brake line lengths are set in the factory to allow optimal glider
control. However, if the setting does not suit you, it is possible to
modify brake line length.
We advise you to use a fisherman’s knot and to keep your length
changes to a minimum (approx 5cm at a time).
The height of the brake retaining strap is adjusted as follows :
- Undo the knot on the brake line and pull it out through the ring.
- Move the brake retaining strap to the desired position using the
straps on the riser and fix it with a loop.
- Feed the brake line through the ring.
- Connect the brake line with the handle on the mark with a fisher-
man's knot.

Be careful not to suppress the “bow” in the brake
line when flying hands up so that the canopy does not deform
or the trims cannot function correctly (if the trailing edge is pulled
tight).
The bow in the brake lines must be checked with trimmers fully
released. The trailing edge must not be affected in this position.

Installing the reserve parachute
and the automatic collapse system on the risers
1. Connect the risers on top of each spreader bar (at the main loop), with the
rectangular stainless steel maillons and the flexible elastic rings. 2. On both sides, push the small collapsing bridle through the main
paraglider carabiner, and connect it to the top of the
« C » riser using a triangular maillon.

PRE-FLIGHT PREPARATION
Unfold the glider then place it on its upper surface in an arc.
Separate A,B,C and D risers and brake line ; make sure that the risers and lines do not have any knots or twists and are not catching anything (stones,
twigs, etc).
Check that both trims are in a symmetrical position.
Caution !
It is crucial to carry out a thorough pre-flight check and in particular to ensure that the passenger and pilot are correctly fastened in their
harnesses and that the harnesses are correctly connected to the spreaders.
Before every take-off, check the following :
- that harnesses and karabiners are in good working order
- that the reserve parachute container is correctly closed and that the handle is in the correct position
- that your personal settings have not been changed
- that the glider is correctly connected to the karabiners and that they are safely locked

Take-off
The design team has strived to produce optimum characteristics for easy inflation in all conditions, whether in light or high winds you will enjoy the
progressive behaviour while launching. However before the first flight, practice ground-handling in order to become familiar with your new glider. It is
possible to inflate with the front- or reverse-launch methods.
Forward launch
In order to inflate the glider, take the A risers in your hands at the maillons and move forward slowly and progressively. Once the glider is above your
head, apply brakes as necessary and perform a visual check before you accelerate for take-off.
Reverse launch
In moderate to high wind speeds, we recommend that you use the reverse launch method in order to facilitate visual control. The pilot should turn
around to face the glider, leaving the passenger facing forward, pull gently on the A risers. After a slight pull to inflate the canopy, move towards
the glider at the appropriate speed in order to prevent any overshooting or dragging. Once the glider has stabilised, the pilot turns around to face
forward and both persons move forward together to take off. Note : it is not necessary to use the A' riser.
Caution !
Before take-off, always ensure that airspace is clear and conditions are suitable for your level of skill and experience.
Trim position
We recommend to set the trims to « neutral » for take-off, which is identified by the red mark on the strap. However you may adapt the trim position
according to wind strength, the take-off slope or the weight of your passenger.
Note : do not alter the trim position by more than one increment at a time.

FLIGHT CARACTERISTICS
The BIPLACE is designed for experienced pilots qualified to fly tandem and fully capable to adapt to various conditions. We recommend that the first
flights should take place in gentle conditions in order to get familiar with the glider.
The following tips will help you to get optimum performance from your SORA tandem :
Flying « hands up » will achieve the best glide ratio in nil wind.
If you require more speed, releasing the trimmers will allow you to accelerate. The glide ratio will not deteriotate much until the half-way point. If you
wish to slow down the glider or to improve your sink rate, pull down the trimmers to bring them to the minimum speed position.
We advise you to use maximum speed (trimmers fully released) prudently and not to fly close to terrain in turbulent conditions in this configu-
ration.

Flight characteristics
Turning
To produce a turn, once you have checked that the airspace is clear, lean into the harness inside the turn – you may also ask the passenger to do
likewise – and progressively pull down the brake on the side where you wish to turn until you have achieved the desired angle of bank. You can then
modulate the speed and radius of the turn by using the external brake. If you are flying at low speed, initiate the turn by releasing the outside brake
first. This will avoid the risk of spinning.
Landing
Always make sure that you have sufficient height to prepare your approach according to the conditions and the particularties of the landing field.
During the approach, do not use sharp turns or radical manœuvres. Always land facing into wind, with the pilot and passenger standing upright and
ready to run if necessary. During the final glide, fly as fast as possible according to the conditions then brake the glider gradually using the full range
of brake travel to completely slow it down as you touch the ground. Be careful not to brake too early or too late. An excessive surge or dive would
cause a hard landing.
If you land in high winds, as soon as you make contact with the ground you will have to turn around with the passenger to face the glider and move
towards it while braking symmetrically. You may also use the C risers to collapse the canopy.

SUP’AIR _SORA Page 14
Tandem glider user’s manual SORA
FAST DESCENTS
The following techniques should only be used in emergencies and require prior training. Appropriate analysis and anticipation of the conditions will
often prevent the need to use fast descent techniques. We advise you to practice in still air and preferably above water.
Big Ears
Pulling big ears increases the glider's sink rate. We do not recommend the use of big ears close to the ground. In order to pull in big ears, grab the
specific riser (outer A riser) while keeping the brakes in hand and lower it until the wintip collapses. It is preferable to collapse one side after the other
and not simultaneously in order to prevent a frontal collapse.
To reopen big ears, release both risers symmetrically. You may apply brake on one side and then the other to facilitate reopening.
IIt is possible to combine big ears with the use of trimmers in order to further increase the sink rate and speed. Once you have induced big ears as
described above, release trimmers fully. Reopen big ears first before pulling the trimmers down to return to normal flight.
Ear blocker
Ear blocker
A system for blocking big ears is
positioned on the rear riser. It will
allow you to lock big ears in and
continue to pilot the wing with the
brakes.
To produce big ears, use the dedi-
cated line (A') and insert it directly
into the blocker at the desired
length.
You will need to adjust your flying,
as the wing has more inertia
when turning in this configuration.
Make sure you anticipate the
reopening by liberating the line
early, in particular before landing.

SUP’AIR _SORA Page 15
Tandem glider user’s manual SORA
Fast descents
360° spiral dives
To begin a spiral dive, make sure airspace is clear then lean into the turn and gradually apply brake on the same side. The glider will perform a full
turn and then accelerate and enter into a spiral. You may use the outside brake to manage your sink rate
In order to exit the rotation, return to a neutral (centered) position in the harness – including the passenger - and gradually release the inside brake.
You need to keep the glider in a turn as it decelerates in order to limit the surge as you exit the spiral. If your exit is too radical the glider will surge
aggressively then perform a big dive, which you will need to keep under control. Gradually slowing down the rotation with the outside brake will allow
you to exit in a controlled manner.
DANGER This manœuvre places a lot of stress on the glider. The high speed and G force might be disorientating for you and
your passenger and, in extreme cases, cause you to “blackout” and lose consciousness. Practice gradually with altitude and a
large safety margin and be conscious of your passenger’s comfort.
This technique is generally very hard to use on a tandem wing due to the high force needed to pull in the B lines. The design of the SORA does not
allow to perform a B-line stall and this technique has not been tested during certification.
B-line stall
As per EN Standards, the SORA shows no tendency to stay in a spiral and will return to normal flight in less than 2 turns.
So as to avoid stressing the paraglider, we do not reccomend combining spiral dives and big ears.

Flight incidents
Parachutal stall
Spin / asymetric stall
Towing
Even though this configuration only occurs very rarely, you might at some point be in a situation where the glider descends vertically with no forward
speed, which is a parachutal stall. If this happens, release the brakes fully and release the trims symmetrically, if necessary you might also need to
push the A risers forward. Make sure that you have regained normal flight before using the brakes.
Stall
This technique is not recommended as it requires very high forces. It is not a safe technique for fast descents.
A spin will only occur because of a piloting error. If so, release the brake fully on the stalled side and make sure you keep the glider in check during
the ensuing dive.
The SORA tandem may be used for towing. Make sure you only use certified towing equipment and with a qualified tow operator. You must also go
through appropriate training. The traction force must be appropriate to the in-flight weight and the towing action must only start once the glider is fully
inflated and stable above the pilot.
Asymmetric collapses
Any paraglider might occasionally collapse due to turbulence or a piloting error. In the event of an asymmetric collapse, you priority must be to stay
clear of terrain and regain level flight. To achieve this, apply weight shift on the open side and, if necessary, help the action by applying an appro-
priate amount of brake on the same side.
If the collapsed side does not automatically open, apply deep brake on the collapsed side and release immediately. Repeat this action as many
times as necessary until the wingtip reopens. In the event of a “cravat” (where the wingtip gets caught up in the lines), you may use the big-ears tech-
nique described above by pulling on the tangled line in order to release the wingtip.
Front collapses
During a front collapse, according to the certification standard the glider is designed to reopen on its own. Make sure you do not apply brake, in order
to facilitate the return to normal flight.
