MAC PARA Eden 5 Series User Manual - Asymmetric Collapse:

active piloting is keeping the glider above your head at all times. We recommend in
principle that you hold the brake handle in your hand whenever possible, or fly with your
hands through the brake handles, to allow you to react immediately to any possible
disturbances.
WARNING!! If you fly with your hands through the brake handles, you may lose valuable
time in activating the rescue system.
Asymmetric collapse:
A negative angle of attack can cause all or part of the leading-edge of the Eden 5 to
collapse (e.g. in turbulent air). Basically the Eden 5 will re-open spontaneously from
closures of up to 70% with a change of direction of up to 360°. The time this takes, and
the associated height loss, can however be noticeably reduced by appropriate action by
the pilot. Apply opposite brake on the inflated side, the outside of the curve, to stop the
turning movement of the canopy. This should be accompanied by appropriate weight-
shift. If you react immediately, 30% brake on the open side should suffice to hold the
canopy on a straight course. In the event of a big collapse, this braking should be applied
very carefully to avoid stalling the remaining inflated wing. The pilot’s correction for
direction can be aided by a pumping out the deflation; a slow, long pumping action of the
brake of the deflated side of the wing helps the canopy to re-inflate. If the glider does not
self recover and the pilot does not correct the canopy can enter a stable spiral dive!
“Cravat” / Line-over:
In the event of some lines becoming tangled during flight (caused by whatever), the
following action is recommended: The pilot stabilizes the glider by gently applying the
brakes. Please be aware that in this condition the brake pressure can be higher and the
brake travel shorter.
Without pilot input a line-over will result in a stable spiral dive.
Here are the various options to untangle a line-over:
pumping the collapsed side.
pulling the stabilizer line or lines causing the problem.
should both measures fail, it may be possible to untangle the line-over by inducing a
full stall. This manoeuvre, however, should only be carried out by advanced pilots
with experience in extreme flight situations and with sufficient altitude available.
Attention! If these manoeuvres fail or if in any doubt, the pilot should instantly use their
emergency parachute system!
Front Tuck:
A front tuck can be induced by strongly pulling the A-risers or by sudden, heavy
turbulence. The entire leading edge spontaneously collapses. Gentle braking on both
sides will reduce the lateral pendulum motions and simultaneously accelerate re-inflation.
