push the speed bar. Never try to steer out of a deep stall and make sure your brakes are 

released completely. 
You can recognise a deep stall by the glider getting "mushy" and the airflow around your ears 

decreasing. Flying in strong turbulence or exiting a deflation with too much brake applied can 

cause this situation. A wet glider also has a higher deep stall tendency. If you pass some rain, 

accelerate a little and never induce big ears in this situation. 

Steering without brakes  

If a brake is not operational for some reason, you can steer the Boomerang 4 with the D-risers. 

Add steering input by weight-shifting in your harness. Be careful not to steer too much with the 

riser to avoid any possibility of a spin. 

Aerobatics 

The Boomerang 4 is not designed for aerobatics and in most countries acro flying is forbidden. 

Besides the inherent risks, extreme manoeuvres of any kind place unnecessary stress on the 

glider and effectively shorten its lifespan. We strongly recommend no acro flying or 

unnecessary manoeuvres on the Boomerang 4 to avoid weakening your glider and especially it’s 

lines! 

Landing with the Boomerang 4 

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 4 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. 
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. 

Tow launch  

The Boomerang 4 is suitable for towing by pilots who have the relevant towing rating. The 

Boomerang 4 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 

Motorized flying with the Boomerang 4 is not recommended.
