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 a part of the leading-edge of the Muse 4 to
collapse (e.g. in turbulent air). Basically the Muse 4 will re-open spontaneously from
closures of up to 70% with a change of direction of up to 90°. 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!
WARNING!! The Muse 4 is a paraglider with special airfoils and with more backwards
positioned A suspension points. These airfoils and position of A suspension points give
more inherent stability and offers more resistance against collapses. It wasn’t necessary
to feature the Muse 4 with special folding lines to perform the maneuver.
But nevertheless
the accelerated asymmetric collapse
must be performed correctly in
a proper way and this preferably by safety trainings.
It is important to take the outermost A1-riser together with A-main riser firmly in one
hand. At the beginning of pulling the move (in the direction of pilot’s body) must be slow
and after the move of cca 5 cm, it can only be strongly pulled down. In case the A1-riser
is not properly held along with the main A-riser, it may happen that the wing tip opens
faster. The opening is then distinctive with the risk of a cravat.
“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 the
deep stall or full stall. This maneuver, however, should only be carried out by
advanced pilots with experience in extreme flight situations and with sufficient altitude
available.
Attention! If these maneuvers fail or if in any doubt, the pilot should instantly use their
emergency parachute system!
