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.
The Muse 5 generally self recovers from an initiated front tuck. When having a very large
front tuck, a frontal rosette can happen (the wingtips move forwards: shaping a horseshoe).
Gentle braking can avoid this deformation.
A quick recognition of the situation and a quick reaction by braking on both sides as long as
the collapsed wing is behind the pilot helps the recovery and limits the altitude loss.
WARNING!! As already described the Muse 5 is a paraglider with shark nose airfoils and
with more backwards positioned A suspension points. These airfoils and postion of A
suspension points give more inherent stability and offers more resistance against collapses.
It wasn`t necessary to feature the Muse 5 with special folding lines to perform the
manoeuver. But nevertheless the accelerated symetric collapse must be performed correctly
in a propper way and this preferably by safety trainings.
It is important to take the two outermost A-lines together (approx 10 cm above the quick
links) firmly in your hands. Do not use the cetnral A-lines! 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. By this way the leading edge collapses properly over its span.
In case you use all A risers for this manoeuvre and you do it without initial pulling it may
happen that the leading edge collapses over all depth in the center of the wing. The result
may be an asymetric opening and the risk of a big cravat increases!
Parachutal stall (deep stall):
In a parachutal stall the paraglider has no forward momentum combined with a high descent
rate. A parachutal stall can be caused by, among other reasons, a too slow exit from a B-line
stall or severe turbulence. Porous canopies (UV influence) or canopies out of trim (stretched
or shrunken lines) are much more susceptible to a parachutal stall and therefore should not
be flown. These are some of the reasons regular checks should be carried out on your
glider. A wet canopy or temperatures below zero centigrade (0°C) may also cause a stable
parachutal stall. The Muse 5 will usually spontaneously recover from a parachutal stall within
2-3 seconds. If the canopy remains in a parachutal stall, it is sufficient to gently push both A
risers forward or to push the accelerator.
Attention! If brakes are applied while in a parachutal stall, the glider may suddenly enter a
full stall!
If a parachutal stall occurs on landing approach, the pilot should prepare for a hard landing
and make a parachute roll landing. In close proximity to the ground, due to the forward
surging pendulum effect, a recovery may be more dangerous than a hard landing in
parachutal stall.
