slope, an adequate use of brakes can help you to take-off more
quickly.
Towing
AYA may be tow-launched. It is the pilot's responsibility to use
suitable harness, attachments and release mechanism. Both
towed pilot and tow machine operator should be qualified to
tow.
When towing pilot must be certain that the paraglider is
completely over your head before you start. In each case the
maximum tow force needs to correspond to the body weight
of the pilot.
4.3. Landing
Because of the exceptional glide, high caution is recommended
in the stages of approach and landing. AYA is an agile glider;
any action on the brakes may cause significant reactions. It is
therefore recommended to execute the first flights in a familiar
environment and under easy conditions. With negative steering
there is more time for the manoeuvres to be performed stead-
ily, which results in reducing the pendulum movements of the
paraglider.
Reminder: Negative steering involves applying the brakes sym-
metrically by about 30% of the maximum range to slow the
paraglider and a simultaneous turning by means of releasing
the outside brake. Speeding up just prior to landing allows a
more effective flare and therefore a gentler landing.
4.4. Turning
AYA was designed to perform well in turns and will core the
thermals even without active piloting. Negative steering (see
above), on the one hand slows the paraglider in certain phases
of the flight and on the other hand reduces excessive rolling
during turn reversals. It is not only designed to turn (with ap-
prox. 30% brake) but also to fly slowly in order to help identify
the areas of lift and to keep the paraglider flatter to minimize
the sink rate in a turn (with 15% brake).
Symmetrical brake-input at 20-30 % enables you to keep your
wing under control – to brake further when pitching and to re-
lease when the canopy
banks up.

4.5. Rapid Descent Techniques

In order to descend, the paraglider must be moved away from
the areas of lift. In case any difficulties occur, the following tech-
niques can be used to increase the sink rate.
Big Ears
Pull at the outside A lines until the wingtips fold back on them-
selves. It is recommended to fold the wingtips separately and
not at the same time.
Keep the lines taut to stop the wingtips from reopening.
Depending on the size of big ears, the sink rate can increase
up to 3–4 m/s.
As soon as the lines are released, the paraglider should spon-
taneously reopen. However, you can speed up the reopening
by „pumping" the brakes. When pumping the brakes it is rec-
ommended that one side of the paraglider be opened after the
other. Pulling both brakes simultaneously can result in a stall.
Spiral Dive
AYA is a manoeuvrable wing that responds to any input easily.
To initiate the spiral apply one brake progressively to about
35% and hold it in its position. The speed of rotation will in-
crease progressively as well as the pressure on the brake and
the centrifugal force that is experienced.
The angle or the speed of rotation can be decreased or in-
creased by releasing or pulling the brake by several centimetres.
Once mastered, the spiral allows you to descend by more
than 10 m/s.
Movements which are extremely abrupt or badly synchro-
nized, or a very quick initiation of the spiral can result in an
asymmetrical collapse or a spin.
Caution: A deep spiral is a demanding manoeuvre. The kinetic
energy obtained must be reduced by slowly releasing the inside

brake and using at least one whole 360 degrees turn to bleed
off this energy.

B-line Stall

Grasp the B risers at the quick links and gently pull them down
symmetrically. The paraglider will drop backwards before enter-
ing in a parachutal stall stabilizing overhead. The descent rate
increases to 6 - 8 m/s.
In order to release the B-line stall, raise both hands togeth-
er in a single quick movement. Once you have released the
B-risers, AYA shall, in principle, resume flight immediately. An
error of control (slow release) or special meteorological condi-
tions may lead to a prolonged phase of parachuting.
The recovery of the paraglider could be then initiated by us-
ing the speed bar. In case there is no speed bar, a short pull
(squeeze) on the A risers (4 – 5 cm) will achieve the same result.
Caution: unlike the big ears and the spiral (see above), in a
B-line stall the glider is in a stalled state. Therefore, a B-line stall
should never be performed close to the ground and in stronger
head winds, a negative ground speed may be experienced.
4.6. Performance & Use of Brakes
AYA's best glide is at trim speed (no brakes) – about 37 km/h.
The minimum sink rate is achieved by applying approx. 15%
of the brakes.
When using more than 30% of the brakes the aerodynamics
and the performance of the glider are likely to deteriorate and
the effort to manoeuvre will increase quickly.
In case of extremely high brake pressure there is a great risk
of an impending stall, which occurs at a full brake travel (100%
of the brakes). In normal flying conditions the optimal position
for the brakes, in terms of performance and safety is within the
first 30% of the braking range.
