With the correct technique & qualified instruction the pilot can learn to help stop collap-
ses by flying “actively” & recover the wing more quickly, by the giving the correct input,
when collapses occur. Remember, the glider is tested to recover and so it is always better
to under-react than to over-react. Over reacting to a situation can prevent the glider from
self-recovering, and recovering air speed, and cause it to enter further unstable situations.
> asymmetrical tuck/collaps
An asymmetric tuck / collapse is when part (one side) of the wing ( say 20% or even any-
thing up to 90% of the span) tucks or collapses, usually induced by turbulence but some-
times also though poor pilot control in turns and wing-overs.
The SYNCRO is tested and certified to automatically recover without correction by the
pilot, but with the correct input the pilot can minimise any turning, and height lose, and
help the glider recover more quickly.
There are 3 basic steps to follow immediately if you have a collapse:
1: Weight shift to the flying side of your glider (away from the collapsed side). This helps
stop the rotation & increases pressure in the wing in the inflated side.
2: If needed apply the correct amount of brake to the open (flying) side to slow any rota-
tion (spiral) induced by the collapse. Be very careful not to use too much brake as its pos-
sible to stall the flying side of the glider, and enter further unstable situations which may
be harder to recover from than the collapse itself.
3: Once the glider has straightened out, or the spiral has slowed, smoothly pull down the
brake on the collapsed side, with a long stroke/pump, & the deflated side of the glider
should re-inflate. As the glider re-opens release the brake immediately but progressively.
With instruction & experience the above will become a reflex action, and the correct
input to give will become second nature to the experienced pilot.
> front/symmetrical tuck collapse
A front tuck /collapse is a symmetric tuck of the leading edge of the wing, starting from
the centre of the canopy to the wing tip. This can be either a tucking of just the central
part of the leading edge of the glider, which can sometimes cause a front 'horseshoe' or
'rosette-ing' of the glider, or even a complete 'blow-out' of the whole canopy in extreme
situations.
When flying, a front tuck may occur while leaving a strong thermal, or more often while
using the speed system in turbulent air, or sometimes whilst flying down-wind of another
paraglider & being 'waked' by the wing tip vortices of the glider and turbulence wake tur-
bulence of the pilot.
Remember, the pilot can learn to help stop collapses by flying 'actively', but if a front tuck
does occur it will easily clear itself. Re-inflating the wing can be helped by correct pilot
