Flight Incidents
Warning: simulation of flight incidents (SFI) should only take place at professional
safety training seminars. They should be held using the highest level of professio-
nal trainer and only while flying over water. For your safety, SFI training should
only be conducted in a very carefully controlled environment: recue boat in posi-
tion, life jacket, well adjusted radio and reserve parachute. Always listen to your
trainers instructions.
Deep/Parachutal Stall
Your CYBER2 has been carefully designed to resist entering deep stall. To prac-
tice a deep stall during SFI training involves flying very slowly, near ¾ of full brake
extension and then modulating the brakes, not quite fully stalling the glider so that
it does not fall back, but stays overhead. Because it is very difficult to achieve on
modern gliders, and can lead to severe complications, it is often omitted from
modern safety training. A deep or parachutal stall occurs when a paraglider has
its usual shape, but is descending vertically without moving forward. In most situ-
ations the CYBER2 will exit deep stall and resume normal flight almost instantly.
In the unusual circumstance that deep stall should occur, reach up and push for-
ward with open palms on both A-risers until normal flight returns. Once in normal
forward flight, it is safe to use brakes again.
Asymmetric Collapse
While flying in turbulent conditions it may occur that a portion of your glider defla-
tes. It also occurs when pilots allow their glider to pitch ahead or behind them or
roll side to side without actively staying with the glider. This may happen to all
paragliders and may happen with your CYBER2 too. An asymmetric collapse
may be simulated during SFI training by reaching up and grasping the A-riser
steel karabiner on one side, and aggressively pulling it down. The leading edge
will tuck on that side and then the pilot releases the A-riser.
It is usually not a dangerous situation, if the pilot takes proper corrective action.
Always look at the good side of the glider, put maximum weight shift on the good
side and maintain flight path by adding the minimum brake necessary. In a small
collapse involving less than 25% of the gliders area, usually the glider re-inflates
after a brief moment, with minimal pilot input, and you can resume your flight.
Larger collapses require aggressive weight shifting away from the collapse and
applying a small amount of brake to control direction.

Asymmetric release of B-Risers: may result in spin.
Releasing risers without releasing brakes as well: may result in deep
stall.
Using brakes directly after exiting: may result in deep or full stall.
Spiral dive
This manoeuvre can result in extreme descent rates and very high vertical and
rotational speeds. Spiral dives with sink rates over 8 m/s are possible but not
recommended. They are dangerous and put unnecessary strain on the glider. If a
pilot looses control while spiral diving, speeds can quickly build up to -20 m/s.
This results in high G-forces on the pilot that can be overwhelming and disorien-
ting. Pilots conducting spiral dives should have collected enough experience to
be mentally and physically prepared for the extreme forces of this manoeuvre.
Spiral dives need time and height to recover. Do not perform this manoeuvre near
the ground.
If you turn your CYBER2 in a series of tight 360s it will enter a spiral dive. This
will result in rapid height loss.
To initiate a spiral, look in the direction you want to go, roll your body weight in
that direction, and then smoothly pull down on the inside brake. Your CYBER2
will first turn almost 360 degrees before it drops in to the spiral. Once in the spi-
ral you must apply a little outside brake to keep the outer wing tip pressurized and
inflated.
Safe descent rates of 8 m/s (500 ft/m) are possible in a spiral dive, but the high
speeds and G-force can be disorientating, so pay particular attention on altitude
and surrounding airspace. While performing a spiral dive you can adjust sink rate
with your outer brake.
If you do not use outside brake and continue to add inside brake while allowing
your body weight to roll inside, the spiral will rapidly accelerate and become more
difficult to regain control and exit.
To exit the spiral dive: slowly release the inside brake; bring your body weight to
the outside of the spiral; and apply a small amount of outside brake. As the
CYBER2
decelerates allow it to continue to turn until enough energy is lost for it
to return to a level flight without an excessive climb and surge.
