PHI FANTASIA, Руководство пользователя, Страница: 10 / 19

Due to the increased drag of the folded wing, the FANTASIA will start to turn to the side of the collapse. At the
same time, the glider pitches forward as a result of the smaller loaded wing surface and therefore higher
wing load and needed airspeed.
The pilot can prevent the glider from pitching and turning, by applying the brake on the non collapsed side
of the wing.
If a collapse occurs close to the ground it is essential to react properly. The proper reaction should be taught
at high altitude, ideally under professional guidance (safety training).
If the brake input on the open side is clearly too strong, it can lead to an asymmetric stall (see spin).
b)Frontal collapse
The front collapse, o en misunderstood as a "front stall", is also a consequence of turbulence. In contrast to
the asymmetric side collapse, the entire leading edge folds down.
The FANTASIA opens automatically from the frontal collapse, as well as the side collapse independently.
To speed up the reopening, we recommend a slight double-sided braking.
7.Stall manoeuvres
a)Spin
A wing rotates negatively when the airflow detaches from one half of the wing. The canopy turns around the
vertical axis with the center of rotation within the span. The inner wing flies backwards.
There are two causes for spinning:
- a brake line is pulled too far and too fast (for example, when introducing the spiral dive too quickly)
- one side is slowed down too much in slow flight (for example during thermal flying)
If an accidentally initiated negative turn is corrected immediately, the FANTASIA goes into normal flight
without any major loss of altitude. The brake that has been pulled too far should be released until the airflow
on the inner wing attaches again.
Attention!
A er a longer negative turn, the paraglider may shoot on one side. This can result in an impulsive collapse or
a cravate.
b)Fullstall
The Fullstall is a complex maneuver whose correct technique can not be fully explained in this manual.
Those who want to learn this maneuver should do so under the supervision of a pilot who masters this
maneuver perfectly - the best way is during a safety training.
The available brake travel down to the stall point depends on the wing size! In turbulent air, the stall can
occur much earlier or significantly later. Those who want to use the full brake travel, must train many full
stalls and get a feeling for the partially or fully developed stall.
c)Parachute Stall
The parachutal stall is a flight condition without forward speed and with a significantly higher sink rate. The
parachutal stall can be initiated by the pilot by strong symmetrical braking and is effectively the precursor to
a full stall.
The FANTASIA automatically exits the parachutal stall by fully releasing the brakes.
