B-line stall

This technique is usually physically demanding and will provoke a parachutal wing configuration and hence wing control will be diminished.
Loosing altitude using the "B" risers is done by grabbing the risers at the metal links level and applying a symmetrical downward vertical pull until
the wing's profile is deformed. This maneuver can be maintained to increase the wing's sink rate.
To regain a normal flying configuration, bring your hands up progressively to the "A" risers red markers, then let go the "B" risers altogether. The
wing will experience a moderate surge forward which will need to be instantly neutralized and controlled.
360° spiral dives
To begin a spiral dive make sure the air space is clear around and below you, then lean toward the chosen side while gradually applying brake/toggle
pressure on that side. The wing will gradually accelerate before entering a full spiral dive. You may use the outer/upper toggle to manage your sink
rate.
In order to exit the rotation, get back to a neutral (centered) position in the harness and gradually release the inside brake. You need to keep the
glider in a turn as it decelerates in order to limit the surge while exiting the spiral. If your exit is too radical the glider will surge aggressively and
experience a substantial dive to be immediately controlled.. Gradually slowing down the rotation with the outside and upper brake will allow you to
exit the spiral in a controlled manner.
To prevent stressing we do not recommend combining spiral dives with "Ears".
Conforming to the EN A, the EIKO 2 glider does not show any tendency to stay in a locked spiral configuration and will return by
itself to a normal flying angle in less than two full rotations when the toggles/brakes are brought back up.
DANGER : This manœuvre places a lot of stress on the glider. The high speed and "G" force might be disorientating and, in extreme
cases, cause you a temporary loss of consciousness. Practice this maneuver gradually with ample space around and below you.
