brakes at a level between your eyes and your shoulders. Use this speed for thermalling and ridge
soaring.
Stall speed is approached by bringing your hands towards your hips. Notice the decreased wind
noise and a signi
fi
cant increase in brake pressure.
Once you have become accustomed to
fl
ying the Boomerang 12, you can practice using the speed
system, which allows improved glide in headwinds and greater penetration in strong winds. During
your
fi
rst few
fl
ights, familiarize yourself with your glider’s speed range and corresponding brake
positions and pressures.
It is important to remember to release any wraps on the brakes when using the speed system. The
brake length on the Boomerang 12 has been
fi
nely tuned to avoid any de
fl
ection on the trailing edge
through the brake during accelerated
fl
ight. Applying brake while using the speed system degrades
performance and increases the chance of collapse.
When
fl
ying accelerated the glider reacts much faster to a collapse. Also the glider reacts more
radically when a collapse happens during accelerated
fl
ight compared to
fl
ying at trim speed.
Apply the speed system by pushing the speed bar progressively with your feet. Avoid
fl
ying
accelerated near the ground, and be careful using the accelerator in turbulence. If you do encounter a
collapse while using the accelerator, immediately step off the bar completely before taking any other
corrective actions.
The Boomerang 12 performs best in turns when it is
fl
own with su
ffi
cient speed and weight-shifting.
Enter a turn with good airspeed, weight-shift and then apply the brake. Once established in the turn,
regulate your speed and turn radius with weight-shift and the outer brake. Too much braking
increases the sink rate.
Make your
fi
rst turns gradual and progressive. Also remember that your harness and its set-up has
an in
fl
uence on the turning behaviour of the wing. The Boomerang 12 has extremely low negative
tendency, so it can also be turned in a tight area by carefully pulling the inside brake line.
If the brakes are applied more, the bank attitude increases and the glider will
fl
y a fast turn
increasing in steepness, which will eventually become a spiral dive (further information on this is in the
section “Spiral Dive”).
Practice active
fl
ying to eliminate collapses in all but the most turbulent conditions.
Keep tension on the brakes approximately equal to the weight of your arms. This allows you to stay
relaxed and sensitively feel the internal pressure in the wing through the brakes. If you feel a loss of
