_____________________________________________________________________________________________________________________________________
WARNING: Counter-steering too strongly on the inated side of the glider can result in a
stall and to further uncontrolled flight manoeuvres (cascade of events).
Always remain aware of other aircraft and terrain when dealing with a problem on your
wing. Do not hesitate to throw your reserve parachute if the rotation in a cravatte is
increasing uncontrollably, especially if you are at low altitude.
Symmetric collapses (Front stall)
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 ight evenly.
WARNING: If you get a collapse while in accelerated ight, release the speed bar
immediately. Then apply the normal procedure for unaccelerated asymmetric collapses.
Types of stall
When a paraglider ies through the air, a laminar and turbulent boundary layer is created. Extremely
dangerous ight congurations can result if the laminar boundary layer is interrupted, with practically
the entire airow along the top surface breaking away. This happens in particular when the angle of
attack is too great.
WARNING: Full stall and spin are manoeuvres which can be fatal if recovery is not correct.
These manoeuvres should therefore be avoided. However, it is important to learn how to
recognise the indications that a glider is about to stall so that you can take immediate action
to prevent it.
There are three di
erent types of stall in paragliding.
Deep stall (parachuting, stable stall)
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 prole characteristics caused by moisture (e.g. 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 airow from the front reduces and the glider goes into a stable ight attitude
without forward momentum. The paraglider sinks almost vertically at 4-5m/s and there is noticeably
less ight noise.
The Evora 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
doesnt recover either put your hands on the A risers and push forward or use the speed bar to
accelerate the wing.
