A negative angle of attack can also cause part or all of the leading edge of the glider to collapse.
Symmetric (frontal) collapses will normally re-open without pilot input. The paraglider will pitch
forward and then regain speed. Assist this process if necessary with a symmetric application of the
brakes. Take care not to apply too much brake for too long as this may stall the wing.
In the case of extreme front stalls across the entire wing chord, the wing tips may move forward
making the glider form a U-shape. Again, recovery is by light symmetrical braking on both sides. Take
care that both wingtips return to normal
fl ight evenly.
Types of stall
When a paraglider fl ies through the air, a laminar and turbulent boundary layer is created. Extremely
dangerous fl ight con fi gurations can result if the laminar boundary layer is interrupted, with practically
the entire air fl ow along the top surface breaking away. This happens in particular when the angle of
attack is too great.
There are three different types of stall in paragliding.
Paragliders can go into a deep stall for a variety of reasons: brake lines too short (no slack), old or
damaged glider material which therefore has increased level of permeability, altered trim/line length
and changes to pro
fi le characteristics caused by moisture (e.g. fl ying in rain). Paragliders have a
particular tendency to stall if the wing-loading is too low. An out-of-trim glider, caused by changes in
line lengths due to prolonged use, may also have a higher deep stall tendency.
In a deep stall, the air fl ow from the front reduces and the glider goes into a stable fl ight attitude
without forward momentum. The paraglider sinks almost vertically at 4-5m/s and there is noticeably
less
fl ight noise.
The Bolero 7 has no tendency to get into a deep stall. Should this nevertheless occur, make sure
your brakes are fully released, the glider will then normally recover on its own immediately. If the
glider still doesn’t recover either put your hands on the A risers and push forward or use the speed
bar to accelerate the wing.
