KEA 2
of porosity in the glider‘s cloth. Whatever the cause, a full
stall can be either symmetrical or a spin.
In both cases the pilot has two possible courses of action:
• If the full stall happens above 100 m it is strongly recom-
mended to execute the stall recovery supposing the pilot is
familiar with the process of such an action (e.i. a complete
execution of the full stall, stabilization of the wing and lift-
ing hands progressively to come back to a normal flight).
• If the full stall happens below 100 m or if the pilot is
unfamiliar with the stall recovery, the reserve should be
deployed immediately.
4.10. Flying Without Brakes
If a brake line or pulley breaks it is possible to fly the KEA2
using the D risers (rear risers). The movements must be well
controlled as the deformation of the wing when pulling on the D
risers is greater than that produced by using the brakes.
Tip: Practice this way of steering to be prepared in case of a
brake failure!
4.11. Comments on the Testing
Procedures
All maneuvers were carried out over water in a stable air mass
with standard temperature, humidity and pressure. They were
carried out by professional pilots trained to react to any prob-
lem in the most appropriate manner.
Test reports are available on the website: www.sky-cz.com.
mum speed of the paraglider by up to 30% of the trim speed.
However, it does reduce the angle of attack and therefore there
is an increased risk of a frontal (or asymmetric) collapse. We
therefore do not advise to use the speed bar near the ground
or in turbulent air.
4.8. Asymmetric or Frontal
(Symmetric) Collapses
Despite that tests proved the KEA 2 recovers on its own after
collapses, active piloting is recommended in case of an asym-
metric or frontal collapse. Active piloting will reduce the loss of
altitude and a change of direction.
In case of a frontal (symmetric) collapse:
• Bring both brakes down symmetrically to speed up the re-
opening of the paraglider, and then raise your hands back
up immediately.
In case of an asymmetric collapse:
• Keep the paraglider flying straight by leaning in the oppo-
site direction of the collapse and simultaneously applying
the brake on the opposite side of the collapse.
• Speed up the reopening of the closed side by a single,
positive input on the collapsed side.
4.9. Full Stall
Certain behaviour or weather conditions can bring about a full
stall. This is a serious incident that can be difficult to manage.
In the case where the stall occurs at less than 100 m above
the ground, it is recommended to use your reserve parachute.
Main Causes of a Full Stall:
• A poorly timed or an extensive use of brakes when the air
speed of the wing is reduced (e. g. when coming out of a
spiral or speeding up after a B-line stall).
• Soaked or heavily drenched leading edge (from rain or a
cloud) can result in a stall due to an uneven airflow over the
leading edge. This process has been related to high levels
4.12. Harness Adjustment
For test flights the pilots used ABS harnesses with the following
set-up:
Size
Distance from
seat board
Distance between
hanging points
KEA 2 XS
39-41 cm
38-42 cm
KEA 2 S
40-42 cm
39-43 cm
KEA 2 M
41-43 cm
40-44 cm
KEA 2 L
42-44 cm
42-46 cm
KEA 2 XL
43-45 cm
43-47 cm
We recommend adjusting the harness in a very similar way to
the test adjustment. Excessive cross-bracing increases the risk
of twisting the risers. A looser setting will result in a tendency to
lean towards the collapsed side. Lower hang points reduce the
roll-stability of your harness and can slow down the reopening
of asymmetric collapses. Higher hang points (+ 2–4 cm) have
no influence on inflight safety and can therefore be tolerated.
