weightshift actively to the outside of the turn and pull the outer brake until you feel the
deceleration of the wing and your body moving towards a more upright position. Then, release
the outer brake and let the glider decelerate for one or two more turns. Apply a short brake
action on the inside brake just before the glider exits the spiral dive completely. This will burn
off the remaining energy and avoid a big pendulum moment after exiting the spiral.
We advise you to limit the sink rate of the spiral to a maximum of 14 m/s and always maintain
ground clearance of 150 – 200m. It is possible to reach a much higher sink rate but the following
risks of increases with higher sink rates:
 cause a loss of consciousness
 lose control over the flight manoeuvre and sink rate, the glider will go into a stable
spiral. If this happens, immediately deploy your reserve!
 stress loading and/or loss of consciousness can occur during the spiral which make
subsequent recovery impossible
Landing
The Boomerang 10 has good handling and completely normal landing characteristics, so no
special techniques are required. Select a familiar landing area free of obstacles and carefully
note the wind speed and direction in the landing area. The minimum flying speed and big flaring
reserve of the Boomerang 10 will help you to make a soft landing in all conditions. Approach the
landing with sufficient airspeed and don't leave your last turn too late or too steep.
Do not pump the brakes to degrade the glide angle, you risk entering a deep stall. Always fly
with sufficient speed when you are near the ground (well above stall speed) to avoid an
unintentional stall.
Before landing, slide your legs forward in the harness so that you adopt the standing position.
Never land in the seated position; it is very dangerous for your back even if you have back
protection, which is only a passive safety system. Standing up before landing is an active
safety system, and is much more effective.
Types of use
The Boomerang 10 was developed and tested for use solely as a paraglider for foot launch. Any
use other than as intended is prohibited.
Tow launch
The Boomerang 10 is suitable for towing by suitably qualified pilots. The Boomerang 10 has no
tendencies towards deep stall/parachuting. There is sufficient margin to counter steer the
glider in a normal towing situation. Make sure you use proper equipment, experienced personnel,
the recommended techniques and all relevant safety precautions for towing.
Motorized flight
The Boomerang 10 has not been developed for motorized flight.
