pressure in one or both sides of the wing, quickly apply the appropriate brake(s) to regain pressure.
Release the brake promptly as soon as normal pressure is resumed.
If you miss the above timing and get a collapse, be sure to fi rst raise your hands and release the
brakes before considering any other corrective actions.
The Boomerang 12 has excellent pitch stability. Nonetheless, in turbulence or during manoeuvres,
the glider may pitch. If the glider pitches in front of you, apply brake to slow it down. If the glider drops
behind you, ease off the brakes to allow it to speed up. The objective is to reduce the pendulum
effect by adjusting the speed of your glider so that glider and pilot are travelling at the same speed.
The same general principles also apply when gliding on bar.
Summary: "Active fl ying"
● The pilot sits upright in his harness, his view goes in the direction of the fl ight.
● He constantly responds to increasing and decreasing brake pressures with the aim of
maintaining a constant pressure on the brake lines.
● The further in front of you the glider pitches, the larger the brake input required, but for a
shorter duration.
● When brake pressures decrease, brake fi rmly; when brake pressures increase, ease off the
brakes.
The Boomerang 12 responds very nicely to B-riser control to fl uidly pilot the wing through turbulence.
The aim is to control pitch so that the wing stays directly above you. B-riser control can also be used
for steering.
Following lifting lines using the B-risers can make a huge difference to fl ight performance and gives
the Boomerang 12 pilot a very satisfying feeling of being connected to the air movements. A pilot fully
in tune with the Boomerang 12 can use these B-riser inputs to follow the lifty lines that lead to the
cores of thermals.
With the speed system applied, the B risers can be pulled downwards to directly control the angle of
attack of the glider. Pulling downwards pitches the nose up, which increases the angle of attack and
reduces the chordwise compression in the sail from the lines. This makes the wing more
tuck-resistant.
If you use B-riser control keep the brake handles in your hand and loosen any wraps of the brake
line. The control movement is subtle and fl uid – only small movements are required. It is important to
recognize how much B-riser movement is needed to return the glider to trim speed. It is good practice
to glide with gentle tension applied to the B-risers (pulling them downwards about 3 to 5 cm) so that
you can feel the inputs from the wing. Those inputs warn you when turbulence is coming, but also
allow you to feel the lifty side of the wing – when the tension on the B-riser on one side increases, pull
down on that side to turn slightly towards the lifting air.
