- Behavior in extreme maneuvers and collapses
Warning
Extreme maneuvers must be executed under the supervision of a qualified instructor,
on safe courses and with the entire infrastructure available for above ground and
water flying!
Lateral Asymmetric Closing
Like any other canopy, a negative angle of attack will result in a closing. In order to
maintain directional control upon a lateral asymmetric closing, the brakes must be
applied on the open side. In case of a major closing, the amount of braking must be
well graduated, in such way to avoid the airflow displacement (stall) on the open
section of the canopy.
To facilitate the canopy re-inflation during a collapse, the steps above must be
followed in conjunction with a long and slow brake pumping action (2 seconds) with
the toggle on the closed side. The shifting of weight on the opposite side riser of the
closing will also assist with the re-inflation and increase safety, requiring less brake
action and keeping away from the stall point.
In case the pilot does not compensate with the brakes, the

can make a complete turn and in the event it does not open on its own.
Without action, the paraglider will begin a positive spiral. The pilot must lightly apply
the brake on the external side to stop a spiral and at the same time shift his/her weight
on the same side until the canopy is stabilized. Exactly at this stage of pendulum effect
under the canopy, it is important that the pilot controls carefully the amount of force
applied on the brakes, and often it is needed to decrease the force. Once a straight
flight is achieved, the closed side can be re-inflated by the pumping action.
Warning
If the pilot does not actively terminate the spiral, it will continue all the
way to the ground!
