conditions the Avax XC5 will recover normal flight automatically as soon as the front risers
are released. Applying (pumping?)the brakes on both sides simultaneously can help re-open
the paraglider.
Caution
:
XC5 has been certified with folding lines.
Without using folding lines SIV
manoeuvres like Asymmetric collapse and Full Frontal Collapse might be very hard to
perform to a desired parameters specified by certification rules.
5.3.3. Deep Stall
Initiation:
Pull both brakes smoothly until the sink rate increases markedly and the forward
speed reaches almost zero. The pull on the brakes should be controlled so that the canopy
stays inflated and doesn’t fall back into a full stall.
Recovery:
The Avax XC5 cannot stay in deep stall flight, so after the brakes are released the
glider automatically returns to a normal flight. If you need to, you can accelerate recovery by
pulling hard on both brakes, followed by a fast release. Or you can pull lightly on the A-risers.
Caution:
If you pull too hard on the A-risers you may experience a full frontal collapse.
5.3.4 Full Stall
Initiation:
Wind the control lines once around your hands and pull both of them down
smoothly. Hold them down until the canopy falls behind the pilot and deforms into a
characteristic crescent shape. Hold your hands firmly (press them underneath the seat) and
be careful that you do not release the brakes prematurely or asymmetrically.
Recovery:
The Avax XC5 recovers from a full stall automatically once the brakes are smoothly
released. During correct recovery from a full stall the Avax XC5 shows no extreme tendencies
such as diving in front of the pilot. If the brakes are released prematurely or too quickly
there is a possible tendency for the glider to dive ahead of the pilot. This can be corrected by
adequate simultaneous braking on both-sides.
Caution:
When exiting a Full Stall, if the brakes are released asymmetrically the glider may
suffer a massive asymmetrical collapse followed by a tendency to enter a spin.
5.3.5 Negative Spin
Initiation:
Slow down by braking to nearly minimum speed. Then pull a brake on one side
all the way down while simultaneously releasing the brake on the other side. Because the
stalled side falls back, the canopy suffers airflow disruption over one half of the wing which
results in a spin and a rapid loss of altitude.
Recovery:
Under normal circumstances the Avax XC5 is capable of recovering from a negative
spin automatically when the brakes are released.
Caution:
In general, when there is a very fast or a long-lasting rotation and when the brakes
are released too quickly, the canopy may shoot in front of the pilot followed by a massive
asymmetrical collapse.
Warning:
Whenever a paraglider is not in a normal flight and the airflow is disrupted there is
always a rapid increase in sink rate and therefore a substantial loss of altitude.
Remember:
When practising SIV the wrong manoeuvre at the wrong time may change a
fairly easy situation into a dangerous problem. You are also exposing your glider to forces
that may damage it. Practise SIV manoeuvres only under the supervision of an instructor and
with a reserve parachute.
