B-line Stall

: B-line Stall Grasp the B risers at the quick links and pull them down symmetrically. The paraglider will enter a B-line stall and
drop backwards before stabilizing overhead. The descent rate increases to 6 - 8 m/s. To exit the B-line stall raise both hands together in a
single, positive movement so that the risers are at full extension. On releasing the B-risers, your Cosmos should return immediately to
normal flight.

• Big Ears

: Big ears is a moderate descent method, reaching -3 or -4 m/s, speed reduces slightly between 3 and 5 km/h and piloting
becomes limited. The angle of attack and the wing loading also increases.
Push on the accelerator to restore the wing's horizontal speed and the angle of attack. To activate ears, take the line amain3 and
simultaneously, smoothly pull them outward and downward. The wingtips will fold in. Let go of the lines and the ears will re-inflate
automatically. If they do not re-inflate, gently pull on one of the brake lines first and then on the opposite side. For directional control
while using the Big Ears, use weight shift.
We recommend the pilot to re-inflate asymmetrically, to avoid unnecessary change on the angle of attack, more so if you are flying near the
ground or flying in turbulence.
PERFORMANCE & USE OF BRAKES

Use of Brakes

Flow Cosmos's best glide is at a trim speed (no brakes) – about 38 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 a stall. Which occurs at a full brake travel (100%
of the brakes) 65cm. In normal flying conditions the optimal position for the brakes, in terms of performance and safety, is within the top third
level of the braking range.

Use of Speed Bar

Flow Cosmos is equipped with a speed system. The profile of Cosmos has been designed to fly stable through its entire speed range. It is useful
to accelerate when flying in strong winds or in extreme descending air. For fitting and positioning the speed bar consult the instructions of the
