Canopy Collapses
a
}
Asymmetric collapses are caused by the stagnation point moving to the trailing edge of the
glider. A negative angle of attack makes part of the canopy collapse and tuck under, and the
glider may plunge down, turn away or spin.
Use active
fl
ying techniques to virtually eliminate collapses in normal
fl
ying conditions.
Nevertheless, if you do get a collapse, stabilize your weight in your harness and do not allow
yourself to fall to the collapsed side. Control your course with weight shift and a little outside
brake. The de
fl
ation should re-in
fl
ate spontaneously.
If the de
fl
ation does not re-in
fl
ate spontaneously, apply brake on the closed side in a smooth,
progressive pumping action. Be sure not to apply too much brake too slowly as this may risk a
stall. Remember that a partly collapsed wing has a reduced surface area and thus a higher stall
speed.
If you get a collapse while in accelerated
fl
ight, release the speed bar immediately. Then apply
the normal procedure for unaccelerated asymmetric collapses.

A cravatte occurs when a wing tip becomes stuck between the glider lines, for example,
following a bad take-off preparation. On the Yeti Tandem 3, a cravatte is unlikely to occur. If you
do get a cravatte,
fi
rst control your direction. Do this by using weight shift and enough
counter-brake to stop the turn, but not too much to risk a stall of the opposite side.
A cravat can generally be opened by a short, fast pull on the brake line of the cravatted side. If
not, on the Yeti Tandem 3, there is a separate stabilizer/winglet main line that goes down to the
A2 riser. This line usually becomes slack in the event of a cravat. Pull this line down completely
until it becomes tight and the cravat normally comes out.
