CAUTION: Never apply the brakes,
including any wraps taken, in a deep
stall.
WARNING: During any incident in flight,
always monitor your altitude. If you
have any doubt that you have sufficient
height for recovery, deploy your
reserve without hesitation. “If low, then
throw”.
Incidents in flight
Asymmetric collapses
Use active flying techniques to virtually eliminate collapses in normal flying 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 weightshift and a little outside
brake. The deflation should re-inflate spontaneously.
If the deflation does not re-inflate 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.
Symmetric collapses
Symmetric (frontal) collapses will normally re-open without pilot input. 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.
Cravattes
A cravatte occurs when a wing tip becomes stuck between the glider lines, for example,
following a bad take-off preparation. On the Yeti 4 a cravatte is unlikely to occur. If you do get a
cravatte, first control your direction. Do this by using weightshift and enough counter-brake to
stop the turn, but not too much to risk a stall of the opposite side. Then pull down the stabilo line
(STB-see line plan) until it becomes tight. This normally frees the cravatte. If not, the last resort
to attempt recovery is to make a full stall (symmetric or asymmetric). Do not attempt this unless
