Full Stall - SKY PARAGLIDERS FIDES 5 S Mode D'emploi

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 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 recommended to
execute the stall recovery supposing the pilot is familiar with the process
of such an action (i.e. a complete execution of the full stall, stabilization of
the wing and lifting 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.
10) Flying Without brakes
If a brake line or pulley breaks it is possible to fly the FIDES 5 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!
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 problem in the most appropriate manner.
Test reports are available on the website: www.sky-cz.com.
12) adjustment of the harness
For test flights the pilots used ABS harnesses with the following set-up:
Distance from
Size
seat board
FIDES 5 S 40-42 cm
FIDES 5 M 41-43 cm
FIDES 5 L 42-44 cm
FIDES 5 XL 43-45 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.
