Pilot’s manual BiGolden2 Version no. 1, from 27.4.2009
5.3.1. Collapse of one side of the canopy
- initiation: Take hold of the outer A-lines on one side and pull them down
smoothly. The wing tip will collapse downward forming a characteristic "big ear".
The size of the ear depends on the depth to which the lines are pulled as well as
the number of lines pulled down. You can stop any tendencies to turn by
applying the opposite brake and by weight shifting onto the inflated side of the
canopy.
- recovery: Under normal conditions BiGolden2 will re-inflate spontaneously
when the pulled lines are released. The inflation time and loss of altitude can be
reduced by suitable action of the pilot. To stop any tendencies to turn off course
pull brake on the inflated side (be careful not to overreact and stall the inflated
side) and weight shift to that side. If the collapse remains then reinflate the
collapsed side by "pumping" the brake on the collapsed side to quicken the
inflation.
5.3.2. Frontal collapse of canopy
- initiation: Take hold at the top of both A-risers and pull them down until the
leading edge collapses.
- recovery: In normal conditions BiGolden2 recovers normal flight automatically
as soon as the front risers are released. Opening may be assisted by applying
the brakes on both sides simultaneously.
5.3.3. Deep stall ("sackflug")
- initiation: Pull both brakes smoothly until the sink rate increase markedly and
the forward speed reaches almost zero. The pull on the brakes should be
controlled so that the canopy stays inflated and doesn't fall back into a full stall.
- recovery: BiGolden2 cannot stay in this regime of deep stall flight, so after the
brakes are released the glider automatically and returns into normal flight. If you
need to, you may accelerate the recovery of the glider by one of two methods:
Either you can pull both brakes intensely followed by a fast release of brakes or
you can pull on the A-risers lightly.
Caution: If you pull on the A-risers too intensely you may experience a frontal
collapse of the leading edge.
5.3.4 Negative spin
- initiation: Slow down by braking to nearly minimum speed. Then pull a brake
on one side all the way down while simultaneously releasing the brake on the
other side. Because the stalled side falls back, the canopy suffers air flow
