ATTENTION: In a stable spiral the G-forces are very high. Be aware that it may therefore
require considerable more input and effort to recover from this state.
ATTENTION: The RISE is a high performance agile glider. When exiting a spiral too fast the
conversion of energy may result in the glider climbing quickly and entering its own turbulence.
This may cause the glider to collapse. We advise that you allow the RISE to exit from the spiral
dive in a controlled manner.
You should take care to use only moderate spirals so as not to put unnecessary load on you
and your lines.
IMPORTANT SATEFY NOTICE! A pilot who is dehydrated and/or not accustomed to spiralling
can lose consciousness during a steep spiral dive!
ii.
B-line stall
This is an effective way of making a moderate to rapid descent but doesn’t allow any forward
speed.
Initiation: Take hold of the B-risers (both sides at same time) just above the maillons and slowly
but smoothly pull them down, twisting your hands until the canopy shows a span-wise crease
at the B-line attachment points and stops flying forward. It is difficult to pull at first but
becomes easier as the aerofoil creases. Your sink rate will increase while your forward speed
will reduce to practically zero. Don’t release the lines immediately - the glider should be left to
settle before releasing.
Recovery: Let go of the risers smoothly but determinedly and symmetrically, the glider will
speed up and gain forward movement. The brakes are kept in the pilots hands at all time
during this manoeuvre. When exiting take care not to pull the brakes. If the risers are released
slowly and very unevenly the glider could start to spin.
iii.
“Big-ears“
This is the easiest and safest technique for descent while maintaining forward speed.
Depending on how much of the wing-tip you deflate, 3m/s to 5m/s sink rate can be achieved.
While in big-ears your forward speed can be increased by using the speed system.
The tendency for the wing to collapse is reduced while flying with big-ears.
The RISE can be steered with big ears in by weight-shift alone.
Initiation: Reach up high and take hold of the metal maillon (quick-link) of the “baby” A-riser
(separate, outside A-riser) on each side of the glider. Pull one in first, maintain direction, and
then pull in the second. Hold them in firmly. The tips will fold in. Make sure the lines are pulled
down equally on each side and your big ears are even.
Recovery: Under normal circumstances the ears will come out on their own slowly when the
“baby” A-risers are released. Occasionally the ears might stay slightly tucked under but a gentle
pump on the brakes will accelerate the opening.
