Boomerang 12 user manual
_____________________________________________________________________________________________________________________________________
The “G-chute” safety device is a small “Anti-G”-type drag parachute that reduces the high
G forces which may occur during the descent in a spiral dive. This enables the pilot to achieve a
higher rate of descent with fewer turns and allows safer spiral descents by reducing
G forces in a spiral dive.
The G-chute is simple and easy to use and usually connected to a carabiner on the harness. It is
deployed before the spiral and pulled back after the manoeuvre is fi nished and stowed away in the
harness.
The Genie Race harness, specially developed for XC and competition fl ights, has an additional
pocket and bridle connecting for the use of the G-chute.
To increase your sink rate, fi rst apply a little speed bar (about 25%) and then pull in the (outer) B3 lines
simultaneously, fi rmly and progressively. To exit the manoeuvre, release the tips simultaneously and
progressively and then release the speedbar.
It is not recommended to do big ears on the Boomerang 12. The manoeuvre is technically possible,
but it takes great arm strength to hold in the ears and the glider loses structure when the ears are in.
Furthermore, the thin Aramid lines can damage the fabric.
!
This manoeuvre is not possible with the Boomerang 12. For fast descent use a steep spiral or
B3-Descent as described above.
Landing
Land on a large and obstacle-free landing site. Fly a straight fi nal approach at trim speed into the
wind. About one meter above the ground, pull both brakes smartly about half the control distance (30
to 40 centimeters), which allows the wing to pass into a short, almost ground-parallel glide (level
fl ight
path). Immediately before touching the ground, both brakes are then pulled completely.
The weaker the headwind, the more energetic and deeper the fi nal braking must be. In the case of
stronger headwinds, the fi nal braking must not be too abrupt. In very strong winds, the brakes are not
pulled down completely to avoid the glider climbing rapidly upwards and backwards. Instead, turn to
face your wing as soon as your feet touch the ground without pulling the brake.
Stall the glider as rapidly as possible with the rear risers. Be prepared to run towards your wing.
Never perform spirals or steep turns near the ground. This may cause the pilot to pendulum
dangerously.
Before landing, you should slip out of the seat board of the harness and assume an upright position.
Never land without fi rst getting up; landings on the backside are dangerous and can lead to injuries
even if you use a good back protector.
