To accomplish this maneuver, take the most external slings of A-risers (which go to the
outer edges of the wing) and tighten them until the wing ends are folded.
To simplify the tightening of these lines they are put on separate straps on the risers.
To increase the horizontal and vertical speeds in this mode, you can release the trim tabs,
but only AFTER folding the ears.
During this maneuver, it is strictly recommended not to make deep spirals, as this negative-
ly affects the strength and geometry of the sling system.
To exit, simply release the held lines and fill the wing yourself. It is possible to accelerate
the opening with the help of a not very intensive pumping of the wing by the brakes.
Before performing a deep spiral, make sure that there is sufficient margin of elevation
above the terrain.
To enter the spiral, transfer the weight in the suspension system to one side and gently
tighten the brake on the same side until the wing starts to rotate.
When the wing increases the angle of heel and accelerates to a certain reduction, hold the
brake in this position.
The rate of decrease can be controlled by weight transfer in the suspension system and
small impacts of the external (from the rotation) brake.
To exit from a deep spiral simply smoothly release the internal (working) brake and the
paraglider will start its own exit.
For a smoother exit, it may sometimes be necessary to apply a slight brake to the wing
to compensate for small wing movements in the pitch before final exit into a normal
straight flight.
AERO MASTER under normal flight conditions has no tendency to remain in the spiral
on its own.
It should always be remembered that the greater the rate of decline in the spiral, the
more time it can take to exit into a normal flight.
Never attempt an abrupt escape from a deep spiral - this can lead to very dangerous
11
abnormal flight situations.
