PHI FANTASIA, Руководство пользователя, Страница: 9 / 19

If you pull too far, the glider starts to rotate slowly around its vertical axis. In this case, the hands should be
raised again until the rotation stops. (A rotation can also be caused by asymmetric pull).
The B-stall is recovered again by quickly moving the hands upwards.
The brake is held throughout the maneuver (without additional wrapping around the hand). During the
recovery, make sure that the brake is fully released.
c)Deep spiral
The deep spiral is the most demanding fast descent and should only be learned at high altitudes, ideally as
part of a safety training course.
The initiation can be divided into two phases:
First, you fly a turn by applying one brake and by shi ing your weight to the same side, the glider will bank
up and increase its turning speed. Then the g-forces increase rapidly and the leading edge will lean towards
the ground. In a fully developed deep spiral, the leading edge is almost parallel to the ground. The maximum
sink rate with the FANTASIA can get up to 25m/s and more.
The first attempts to fly a deep spiral should be stopped clearly before reaching a fully developed deep spiral
to get used to the quick rotation and to practice the exit without pendulum swinging. The exit should be
performed by simply releasing the inner brake with a neutral weight-shi . The FANTASIA will then decrease
its bank angle and go back to normal flight. To avoid a pendulum movement, the inner brake has to be
pulled in the moment the wing wants to reduce its bank rapidly.
The actual spiral movement begins with the leading edge nearly parallel to the horizon. At this moment the
harness banks and the pilot is pushed to the outside of the rotation movement. The pilot should allow this
movement to avoid a stable spiral situation. (see below). Now the sink values can be varied by inner and
outer brake.
If the pilot weight shi s to the outer side, the spiral movement will get slower as soon as the pilot releases
the inner brake. The rest of the exit works as explained above.
If the pilot shi s his weight significantly inwards, the FANTASIA can continue to spiral when releasing both
brakes. In this case apply both brakes simultaneously or brake the outside of the turn and of course shi
your weight to the outside.
The sink values in the spiral can be between 10m/s and 20m/s. The load on the body is over 4g and can lead
to unconsciousness depending on the physical constitution of the pilot.
So it is important that you slowly approach this maneuver in order to master the maneuver actively and
confidently, and to know the reaction of the body in this demanding situation of high g-forces.
Attention!
Actively exiting a stable deep spiral requires an unusually large amount of body force due to the high g-load!
Attention!
Due to the high performance and dynamics of the wing you have to expect that the glider climbs up some
altitude a er the release of the deep spiral and can hit its own vortex turbulence!
6.Collapse
a)Asymmetric collapse
When entering strong turbulence, one side of the paraglider may collapse. Specifically, this happens when
one side of the wing is losing li by decreased or negative angle of attack. As a result the lines are getting
unloaded and the wing is collapsing.
When such a collapse only affects a small part of the span the FANTASIA will show no significant reaction. For
larger collapses with more than 50% of the span affected, the glider shows a more dynamic reaction:
